Multiple government studies have shown that staying between say, 40-60% can have a standard battery last millions of cycles, literally. Most of those side effects are due to charging/discharging at extremes. But yes, keeping your battery relatively cool is probably the most important for a smartphone.
Rene you are so so missed on MBW. I know your new job is fulfilling but it feels like we’ve lost you in a Apple sphere. There’s no one else that does what you do. You’re missed pal
Rene missed the point in a few ways: 1. There are people who intentionally drain their battery everyday because they think that's better than just topping up. This is worse than topping up throughout the day. You mentioned that it's not bad to let your phone below 20%. Technically, that's false. It's best to top up during the day and not drop below 20% as much as possible. 2. There are a LOT (hundreds of millions) of people who do not have an Apple Store near them, especially in Europe and Asia, (especially hot parts of Asia) where managing the battery means a LOT more to them than the average American. My fiancè had 0 Apple Stores on her entire island. So for people like her, managing the battery is something that matters. Unfortunately this video assumes that everyone has $70 to spend on an extra battery and lives near an Apple Store, when that's just not the case. Sure, I live in the USA and have a lot of disposable income and can easily just buy a new iPhone if my battery health drops, but millions of people do not have that luxury, nor an Apple Store nearby. That's a problem I've noticed with a LOT of Rene's videos. But overall, I do agree most Americans should likely not worry too much about their battery health.
I live in the philippines, its pretty hot here and original iphone batteries here are extremely expensive, more than 100 dollars. They will also ship your phone outside the country , i think in singapore so you will wait for a month just for a single battery. So i agree we need to micromanage our batteries here. I learn it the hard way when i neglect my 12 mini battery.
I kept my iPhone 12 Pro's battery between 40 and 80 and it was still at 100% capacity after 18 months. I charged it "normally" for 6 months and lost 6% of the battery capacity.
I really very much doubt that a battery can be at 100% capacity after 18 months, no matter what someone does beyond just packing up the device and not using it for 18 months. (And even then I still don't think it would be at 100%.)
It could’ve been that the cell in your phone was quite a bit larger than the nominal capacity so you were initially burning through that extra. Also keeping the charge between 40 and 80 suggests that you didn’t use the phone much so you would’ve had less charge/discharge cycles
I'm at ~80% on my XS (after 3years) but it gives me a warning message saying battery is in critical health and needs to be serviced. Battery burns really really fast. But I'm upgrading to the 14 Pro soon anways.
What phones are you using that have easily replaceable batteries? As far as I was aware pretty much all modern phones have their batteries hard-fixed to the motherboards. The battery is the deciding factor of when I'm going to get rid of a phone and I'm sure its that way for a lot of people too. Manufacturers would certainly be aware of this and holding onto the same phone for 6 or 7 years just doesn't cut it from a business standpoint when they know they can get the majority to swap phones every 2 to 3 years at least, so why try to eek more usable life out of the battery? I only charge with the slow charging from my computers USB port or the 12v charger in my car, if I plug it into the wall with the max power charger it gets uncomfortably hot.
users wanted it, and they got it. As convent as thing things have become, i'm not about to introduce problems myself.. And if i live in the 'stone-age'' then so be it *picks up my club and i drag my sister into the cave*
I’ve had my iPhone 13 Pro Max since release day and it is still at 100% battery health, with moderate usage everyday. Compare that to my iPhone 11 Pro Max which lost well over 10% in its first year! Apples focus on improving battery health is showing
‘Battery capacity’ kinda feels like a lie to me. I’ve had an iPhone 11 for over 2 years it’s at 89% capacity but the battery performs really well with minimal use I can get well over 24 hours. Compare that to the phone XR my wife used to have her phone was draining much quicker while at a capacity of 95% or even a little more. That being said I never let my battery go under 40% before charging.
My normal used iphone 12 mini (that really is known for poor battery life) after 1.5 years is still at 100%. I do not know anyone who relies only on battery AI being able to achive this. And it is not that hard to achive this.
The battery percentage health is not accurate, it just calculates the cycle per charge you do then lessen the percent health by the numbers of cycles, so if you are a heavy user like playing heavy demanding games it will wear the battery much quicker and wont be directly proportional to the charge cycle because you drain your battery much faster. I compare same iphone models, one i used for work the other one for gaming and media, always charge both at night with almost same battery percentage. Same battery health right now 89 percent but the gaming iphone drains quicker when comparing just at youtube playback on both devices. The battery health percentage is just a rough estimation per charge cycle not the wear and tear of usage. Hope this helps to clarify :)
I have a iPhone Pro 13. I was leaving it on the with the MagSafe charger day and night. I noticed the phone was getting real hot at night. The first month it got down to 94% Battery Health. I switched back to cable and been charging it to around 80+ % for the past 6 or so months. Battery Health percent stayed at 94 ever since. I don't know if it was a software bug making it heat up or if my phone has a hardware bug or smt but I don't trust Apple's charging logic with this phone. I think iOS 16 has some new check for temperature check with when charging, might give it a go with this phone after I decide to buy a new one.
@@ruialex314 well the usage, cables/bricks, and environmental temps all factor in. Before I upgrade my iPhone 12, I used MagSafe to charge for basically 98% of the time for about 2 years, and it’s now floating at 91% battery health.
@@ReneRitchie However, it's not the same living in Utah than in Florida. Room temperature at night WILL be different, and then inductive charging builds upon that. I guess, at least.
I do have to say though that the primary use of MagSafe to charge my iPhone 12 Pro appeared to shred battery health much faster than I was accustomed to seeing, putting me down to 80-something percent in less than a year.
Same. Mix of magsafe and the 20W fast charger and my 12 PM battery doesn’t even last half a day anymore. I’m going back to the 5W charger for night use on the 14. Will bring faster chargers though for travel
iPhone 13 pro battery at 350 cycles and 97% battery health, a few simple rules that don’t require micromanaging: 1) Try to charge before 20% 2) Enable optimized battery charging 3) Cool down the phone after intense heat. I love being out in the Texas heat, and my phone has felt plenty of it. I just put my phone in front of a fan for 2-3 minutes so that it’s cool to the touch That’s it. I almost never use my phone while charging it either, since it’ll be up to 80% or more so quickly anyways.
I agree, the point of charging it from 20 to 80 is to save the battery health, but you're technically only using 60 percent of it which defeats the purpose of saving the battery as if you only have "60 percent batter health" remaining, seems way more complicated and stressful than to just replace the battery every few years
I went to Apple Store for replace new battery after one year uesd my iPhone 13 Pro,but they suggests me to change my habit or charge behavior instead change battery,but I insisted to changed new battery and now just like new phone 😆
Don't see the problem. The reason is to preserve as much of the 100% for the few days where you can't charge during the day. For normal days 60% should be more than enough as your going to be near the charger all the time anyways
@@KK-up3pq if 60 percent is enough for the day, then why put all the struggle to keep the battery health at '100 percent health' at all times? Doesn't makes sense to me
I agree. I got lots more things to focus 🧘♀️ with life than my phone’s battery health. With my workflow I end up charging my iPhone and iPad Pro 2-3 full cycles every day of the week due to the photo shoots and editing runs I do. I could leave them both plugged in when inside the office, but I just charge them during my 30-60 minute breaks in between work.
@@yabibiin find an Apple Authorized repair center. You won’t have to wait as long and they won’t argue about it with you. I’ve replaced batteries that were between 90-95% capacity as I was noticing the change in how long it would last the day, and never have had any gruff about it. If they don’t want your money a 3rd party store will be glad to have your business.
About 3 years ago my dad bought xs max and two months later I bought 11 pro max, I micomanaged my battery and my dad used to leave his phone plugged overnight and whenever he felt like it. Half a year later my phone seemed to keep 100% battery health and my dads phone dropped to 95%… but now 2 and half years later mine is 83% and his 87%, considering we have same level of use, and the fact i was constantly worried about my battery health causing me to use only 60% of it (20-80%), I now realize it wasn’t worth it.
I have had many iPhones over the years. Even with the faster charging, I still use the 5W charger. Every one of my phones when I either sold or traded them, all had 100% battery. Merely throwing it out there for you.
@@JAMESWUERTELE My years of doing it that way have proven it so. I have many friends that use fast chargers. Within approximately 1 to 1-1/2 years, their batteries are at 90% or below. Hard to argue with facts.
@@robbennett The Chinese OEMs have some excellent battery tech, like OPPO, they can charge 1600 times before they reach 80% capacity, whereas the iPhone and Samsung it is nearer 500 total charges. Also, they split the battery so that 60-watt charging is more like 25 watts per battery half.
How many charge cycles do you have? I’m a power-user, using 120-150% of battery per day. Only charging with 5W charger over night but having 400+ cycles per year makes me lose about 8% of capacity per year. And I don’t do gaming, my phone doesn’t get hot often.
My iPhone 7 is sitting at 86% Battery Health with 825 cycles on a 4 year old battery and I've been using a smart battery case on it the whole time. Most of the day it sits at 100% charge all day and only drops to maybe 80% by the end of the day on the internal battery. I don't worry about the battery and it has been perfectly fine!
I tried micromanaging my battery on my iPhone 13 Pro and that somehow caused the battery health to drop to 99% literally less than a month after I bought the phone. I’ll be taking Rene’s advice with my 14 Pro when it arrives later this month. I guess it really is best to just let the phone take care of itself.
the advertised mAh is what the phone sees as 100% so if your battery happens to come with slightly more at max charge then that is why you would see 100% for longer, it doesnt really mean anything, so yeah dont worry and just enjoy your phone
@@lllhunterlll9644 I have about 380 cycles on my iPhone X (according to CoconutBattery, not sure how accurate it truly is), and its at 98% battery health
My 13 pro max always charged it to 100% and sometimes leave on charger unless I go out. And it’s 98% charging capacity after a year. Rene is right. Let the tech do it’s job for you…
I found out after three years and over 800 charge cycles on my iPhone 11 Pro battery, a quick trip to my local Apple store and about $70 got me a fresh battery installed with 0 charge cycles. Would recommend over getting a new phone based on prior phone's battery life.
The 6 month old 13 Pro I just sold, still had 100% battery health. I didn’t do anything special and didn’t babysit the charging or the battery in the slightest. I fast charged whenever and wherever I wanted, when it was dead and overnight, 95% of the time with MagSafe. I must’ve had a great battery?
This is one of the reason I did not turn on battery percentage on on my 13 pro max. I gotten so used to not seeing a percent that when I turned it on. And watched it go down it started to give me anxiety. So I just switched it off and just enjoy the phone and it’s amazing battery
I’ve had an iPhone 13 Pro since October of last year, and I’m at 91% battery health. The problem that I deal with is that Apple doesn’t really let YOU decide when and where to charge your battery up to 80 and then go up from there, it decides for itself using machine learning. I’m a college student that has late nights (or all nighters) working on assignments, and other nights where I fall asleep at 8:00 PM. My iPhone just can’t decide on what my schedule is because *I* can’t decide what my schedule is. So because of the way they designed it, my battery gets zapped into charging full every night in an hour or two, and then is on the charger all night. I really wish they would base it off of your sleep schedule set in Health rather than the presumed schedule they think you’re on, because I don’t always go to sleep at the same time, but I always wake up at the same time. I hope Apple adds this feature in later that allows you to base charging speed/percentages on when your alarm is set for, rather than just an estimate.
@@pureluck8767 According to Apple's own site, "With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged. When the feature is enabled, your iPhone will delay charging past 80% in certain situations. Your iPhone uses on-device machine learning to learn your daily charging routine so that Optimized Battery Charging activates only when your iPhone predicts it will be connected to a charger for an extended period of time. The algorithm aims to ensure that your iPhone is still fully charged when unplugged." Now I will say, when it does engage, it will indeed schedule charging to finish by the time my alarm is set, however it almost never engages as stated for the reasoning above, since my schedule is never consistent. I really just want them to add a feature that says something like, "Between x time and y time, turn on Optimized Charging whenever connected to a charger." That would benefit me greatly, especially since my battery health is getting lower every day
It might sound dumb but get a 5 watt apple charger. I use two apple chargers one 20 watt and one 5 watt. I use the 5 watt to charge overnight cause I don’t need the faster charging speeds when I’m sleeping and use the 20 watt wherever I have to juice it up quickly throughout the day or before heading out for a hike or sth
Spent last two years of my life struggling to keep my iPhone and iPad at below 80% I’m done with stress. My phone is at 92% health my sisters is around 90% and she didn’t do any of that. New Mac chargers so fast I can’t catch it before it gets to 100. I’m just going enjoy my stuff and replace barriers via apple care when needed
I agree with everything except in part with wireless charging. Wireless does generate quite a bit of heat, and while there are solutions for fast wired charging there is not much can that can be done for wireless. But if it's convenient for the user, it's a worthy trade-off... Another thing that should be pointed out is that this applies to iPhones but not to iPads, which don't have battery optimization. Also Android phones don't always have it either (Samsung does) and worst, most Android OEMs do not offer battery servicing...
You're very much mistaken about modern Android phones not having the same smart Battery Technology. Adaptive battery, adaptive charging was on Android long before iOS
@@michaelcorcoran8768 you are saying I am mistaken about something I didn't say.... I never said that modern Android phones don't have adaptive battery for instance. Also when I said battery optimization I meant more than just adapting charging. Adaptive charging works well when you have regular charge habits, but does not work so well when you don't... Samsung phones for instance offer a battery limit of 85% which allows you to leave the phone plugged it any time for any lenght of time. Regadless I din't say that most brands don't have adaptive charging, just that some don't (most actually do today). Nor did I say it came on iOS before Android...
I'll keep saying it. I've kept my iPhone 13 pro max between 40-80 for the last year, when I sold it, it was still on 100. That definitely increased the value when selling.
Even though iPhone is my primary device, I bought a S22 Plus recently to play around with Samsung just makes battery management easier, they gave you a setting to pause charging at 85%, so you can charge anytime and not have to worry. You can easily toggle this setting on or off from notification quick controls. Of course Apple refuses to give us control over anything like we are idiots or something. It’s not about 70 bucks battery replacement costs, it’s about using this planet’s resources wisely, it’s a lot of resources to make these batteries, let’s make the best of it. This is also how EVs work, you set a daily charging limit and then if you need to go on long road trips, you can change it to 100%.
I had my iPhone 11 Pro Max on 100% for over a year, I use 2 Apple Smart Battery cases, once one case dies I switch to the other case, the case gets swapped at 1 percent, it’s died on me a couple times which made me use the phones battery a couple of times
Just program a battery replacement at two years if you plan to ķeep the phone long term. That works as well as any scheme I've come up with to baby the battery.
I don’t believe this, I would charge my iPhone 12 Pro Max overnight and within a year and a half the battery health was at 80%. The smart charging and artificial charging does not work as well as people think it does, it just doesn’t
The feature that phone learns when to stop at 80% and wait till you use to charge to 100, you have to plug in at the same time for 5-7 days straight for the phone to learn your charging habit. If you switch everyday, your phone can't learn since there is no pattern. if this is the feature you talk about,.
You're wrong because neural networks, algorithms, machine learning, artificial intelligence and other buzzwords!!! Lol no the battery chemistry is still there and no fancy words are going to change that. Micromanaging is just not worth the time in my opinion.
I just sold my iPhone 11 Pro Max and I always charged it whenever and however I wanted, the battery was still at peak performance and this is a four year old iPhone.
2 yrs on iphone 12 pro max and battery still at 100%. Use 6 hrs a day on an average both with & without charging cable. Phone is jailbroken - so have a tweak which stops battery charging once the cell’s battery hits 80%.
I rocked an iPhone SE (2016) all these years until last week (not a money issue). The battery health was still saying 90% but i knew it was f00bared. It rebooted on random occasions (voltage drops), and the % dropped just by if you stared the screen funnily LOL. Sure, i could have still replaced the battery but the phone itself was around 10 dollars worth and no more updates after IOS 15. Bite the bullet and finally upgraded to a iPhone 14 Pro few days ago. Talk about milking the last drop of your tech before upgrading. The leap with this upgrade has been magical 🤓
Great video Rene. Always been impressed by your tech content. I 1000% agree. I don’t know why people obsess over battery health. iPhone batteries are $100 or less to replace through Apple & if you have AppleCare + then it’s free when the battery wears down. It’s going to happen. People spend more time babysitting their battery than actually enjoying the device. There are a few common sense things people can do. Don’t leave your phone in extreme heat or extreme cold, use official chargers and I would say don’t run the phone below 20% often and you should be fine. People think because the battery wears out that’s the end of their iPhone when that’s not the case, just get it replaced when that happens.
The problem is apple only replaces battery at 79% or below. There are so many posts on Reddit saying that they won’t do it. Even if you want to pay for it. Then you are stuck at 81% or 80% battery health.
@The Omniverse apple even won't change the battery for a 4 yrs X's Max, so why people bother buying their trash when newer iOS is all about anti third party repair which will disable the battery health. So what's the use of buying iPhones, that are borderline unfixable and you have to throw it in the trash when the battery will die or the phone is permanently bricked creating more e waste???
LOL You got everyone with that 80% explanation!!! "If you only use it to 80% anyway, why would it matter if battery capacity drops to 80%??" logic, my man. 🧐
So why does Apple MagSafe battery keep you at 100% and previously their Smart Battery Cases also keep you at 100% for ages, case also generating a lot of heat!
Battery health: does it matter for battery health whether you charge with a 20w adapter, 60w adapter, or 10w wireless thing? Also, is it bad to leave it on a wireless charging stand all day (even when fully charged) ? Thanks.
Whats wierd is I never thought "Battery health" worked.. Perhaps on the latest iOS AND iPhones but not when using iOS 15 on older ones. My battery health on my iPhone 6s Plus, still shows *100* optimal, yet i know i keep charging my phone regularly than two times a week.. I'm a light user, so under normal circumstances i could go a week and a half without a charge.. Since the iOS15 update, I' been having to charge much more, even though my habits have not changed, and the phone thinks its still "optimal"
Because my 13 pro max has such long battery life I don’t charge it at night but random times throughout the week. Because of this my phone is never charged to 100%, usually 90-95% is when I will pull it off the charger and I’m still at 97% battery capacity a year later.
Multiple government studies have shown that staying between say, 40-60% can have a standard battery last millions of cycles, literally. Most of those side effects are due to charging/discharging at extremes. But yes, keeping your battery relatively cool is probably the most important for a smartphone.
@@bofty it is, that's why battery systems on long-mission systems such as sats go along these lines. When I go to work next week I'll have access to locked public IEEE papers and such and reply with a few titles
@@monsterous289 long term sats wouldn’t use millions of cycles though. Keen to read some papers when you can let me know the titles, I know you can get thousands of cycles, millions with current tech just doesn’t seem right to me
Whenever I wirelessly charge my phone I have it hooked to a AC vent in my truck which keeps it cool and makes charging faster. Accu battery helps me monitor the temperature and charging status.
Just got my iPhone 14 pro and I’m actually shocked how terrible the battery life is. I don’t know if there is something wrong with it but it’s barely making a full day. And I’m not a heavy user at all. Even over night it loses 15-20%. Even though all the background things are turned off.
that is not normal at all, stock ios or did you update? happened to my 13pro after i first updated[15to15.5]. u.s device using it in turkey. so i just sold it.
My iPhone 12 Pro went to 99% after one week, over the next 11 months it dropped to 89%…it’s been at 89% for 13 months now and lasts exactly as long as it did the day I bought it.
what about heat over time from fast charging? my iphone 13 pro gets uncomfortably warm when charging on the 20 watt adapter and heat is a universal no no for batteries.
Don’t agree completely. Sure, it’s true. I still avoid charging to 100% when I don’t need that much runtime. What was just wrong was the ‘wear leveling’ part. That can’t be done in a battery. Maybe you mixed it up with an SSD. But cycling the battery between 60 and 80% doesn’t hurt it anyway.
He says it at beginning of the video, it's OK to charge to 100% but don't leave it there for long periods of time, because that will put strain on your phone.
The $ over the life of battery being minuscule makes sense but honestly it’s the hassle of having to bring it in to apple and the constant power anxiety at the end of a battery’s life that bothers me more so than the cost.
I’m 9 months in on my 13 PMax and I’m still at 100% health. My battery is typically at 45% when I plug it for the night from being used off and on 12:30am to 7pm. With the great battery I only charge it when I’m asleep. I absolutely love my iPhone 13 Pro Max ❤❤
I remember a while back you made a similar video, maybe about the MacBook Pro and I have kept that advise. Actually my M1 work laptop is charging at home to 80% and once I don't charge it and let it drain for a few days it will send the message to plugin and I do it and it takes it to 100% so it is smart as a whip. My iPhone 11 still goes strong as well. I know that after 80% it is maybe shorter but who cares, there are outlets everywhere, except when you need them of course.
The optimization never works for me. I go days on one charge. So when I charge it is irregular so with no pattern it just always charges to 100%. I usually catch it at 92-95 and at that point why not just let it finish
I have a 12 pro max and at 81% battery health. I use MagSafe and I charge over night. When I charge at work and I put it in front of my fan. I try to keep the phone cool when charging now. I think I’ll stop charging over night unless it’s below 30%
I don't baby my battery, but I am mindful. I don't uselessly charge from 0% to 100%. I usually end my day with 15% and then charge to 85%, then 100% during my morning routine. Any top up charge I do is usually only up to 80% it charges the fastest. After just over 1 year (14 months) my health is at 96%
Same. You don't need to do any of those shenanigans. Use your phone at will. Enjoy it. You can always buy a new battery or pass it on to a family member when you bought a new phone
I’ve constantly charged an iPhone for 5 years straight and the battery life hasn’t changed in any significant way. I can’ believe any of this concerns anyone.
Awesome video. My main question tho is if the 20W charger damages battery health overtime, simply because every single time i charge my iphone with the 20W charger (just went from XS to 14 pro max), my phone gets quite hot, even if i unplug it when it reaches 100%. it’s also weird that the 14 pro max came with the usb c cable, so 14 users that don’t have a charger yet have to buy a 20W adapter if they wanna stick with apple’s first party charging blocks. for now i’m sticking with the safest route i know which is apple’s 5W port and USB-A cable.
My XS Max is 4 years old and the battery health is at 92%. I don’t deep cycle it very often. I usually keep it charged at work and at home. I rarely have it go below 50%.
Thanks! How about iPad 9th Generation charging? Can I leave it in the charger all week as it is used to run an audio mixer at church. Should I unplug it after it’s charged?
why then many used iPhone 13 pro on used market sale are 80-90 % health battery and mine is 100% after nearly one year ? :-) I would not worry too much, but keeping it between 30-80% most of the time worked for me. :-)
I live off grid and use lithium batteries as a reserve of power as a result I know a fair bit about them What this bloke says about batteries getting above 80% is correct it's leaving them there for extended periods of time which causes the damage and as most people will charge overnight to 100% and then use it this causes very little degradation in the battery The big thing is letting them get below 20% If you get home from work and are on 30% for example and only charge to say 50% before going out again this is far far better and what you should do rarther than carrying on with your day and letting it get down below 20%
I was literally wondering about this question just yesterday about whether I should care about my charging approach. On my old iPhone X, I had the same battery for 3.75 years and used the phone for 5-7 hrs/day according to my activity charts, routinely charging to 90-100%. I was surprised it lasted that long but I also charged wirelessly 90% of the time so the phone was rarely hot, so I think that played a role in how long the battery lasted before my iPhone 14 came.
I think micromanaging it is a waste. You're basically enduring the kind of limitations that you're trying to prevent. And it's possible they won't even help
Are you serious? I let my iPhone X run down completely and then charge overnight to 100%. I’ve been doing this for years and guess what? No problem. Who has the time to worry about charging until this or charging until that. Give me a break
iPhone battery replacements are so cheap and quick now, that it just makes no sense thinking about batteries at all, even if you are burning through them every two years. Imagine if we could use our cars heavily for two to three years, and the only maintenance we needed to do was a $50 component swap. Heck, I saw a reddit post yesterday of a guy still rocking an iPhone 3G from 2008 as his daily driver still. Even after the battery is worn, the device will likely still work.
Is it bad for the batteries to keep my iPad Pro 12.9” gen 6 & M1 MacBook Air plugged in 24/7? Or keeping my iPhone 13 Pro Max plugged in all night while I sleep?
If apple just gave us one setting the battery would last years longer. That magical setting? Set the max charge to 80% or 90%. This is what Tesla does and as a result the battery in the car lasts many years. Not just two which is the apple goal. Adding the machine learning on top of this is great, like Tesla does. So why does Apple not give us that simple setting? So the battery will wear out and you will get a new phone.
@01:12 an 80% charge on a 100% healthy battery works better than a 100% charge on an 80% healthy battery. They are NOT equivalent. Unhealthy batteries have higher internal resistance, which means that they get hotter when discharging and charging and are unable to provide as much power when their charge is lower, causing a phone with a weak battery to suddenly go from 15% charged to zero when running high demand apps.
My 13 Pro Max is still at 100% capacity because I don’t charge it overnight and often don’t need to charge it everyday. I just charge my phone when I need to and avoid doing it overnight so it isn’t going from 99 to 100 constantly back and forth while I sleep.
Wireless charging is the only charging that could produce a bit more heat. However with official chargers, I have never experienced excess heat. Also do not care about battery health. It is cost-efficient to simply not care and replace the battery when needed
Theory; I think that users that don't micromanage have fewer cycles registered as a result (as sometimes these use it whist it charges/charged), but could have more damage for real health. I've been micromanaging to a crazy level, keeping it between 65-75% at all times. But unsure if any benefit to it. I agree that heat is half of the culprit of the wear, and charging causes heat. For me the jury is out as to what is best practice.
My 13 pro max which I’ve had since launch is still at 100% Battery health! All I do is wirelessly charge every night when I sleep and that’s it! And I’m now doing the same with my 14 pro max!
If you change the iPhone battery after a year or two . The battery performance will be significantly low than it was first bought. For example my iPhone 13 was bought one year ago and battery now is at 90%. If change the battery now from apple. After a year it will be less than 85%.
Hi! Great info thanks 🙏 very reassuring 😄And how does this apply to MacBooks? Should you work with a MacBook plugged in? Does it damage the battery to have it working at 100% all day, every day? Is it better to have a higher cycle-count with less 100%-mileage, or far more 100%-mileage and a really low cycle-count? And, if you do work with the MacBook plugged in, does Apple itself recommend imposing any kind of discharge routine/schedule?? 🙏
Same question especially because I’ve got the Studio Monitor and because it’s always plugged in to my M1 MBPro. In addition I’m using a hub that’s powered in order to get Ethernet soooo as a result my MBPro is “always charging. Will this hurt my MB? What do you suggest?
Yeah phones have had some form of “smart” charging since lithium ion batteries first showed up. I had a Motorola Startac back in 1998 and one of it’s selling features was smart charging, which at the time just meant the phone managed it for you so it would not over charge. This was required with those batteries to prevent them from overheating and potentially exploding. Now as Rene explains it’s all fancy and uses machine learning for optimal charging, but basically you haven’t really had to worry about it that much for over 20 years now.

🪫 How are you charging your iPhone?
Portland, JAMAICA in the Building!!!!
Multiple government studies have shown that staying between say, 40-60% can have a standard battery last millions of cycles, literally. Most of those side effects are due to charging/discharging at extremes.
But yes, keeping your battery relatively cool is probably the most important for a smartphone.
I upgrade my phone every year so I could care less about battery health. Faster is always better for me.
@@AppleReviews I talk to him all the time, we're on the same page :)
Rene you are so so missed on MBW. I know your new job is fulfilling but it feels like we’ve lost you in a Apple sphere. There’s no one else that does what you do. You’re missed pal
Thank you so much, I miss it as well!
@@ReneRitchie yes. You’re absolutely missed Rene. Please come back. Don’t forget us. ❤❤❤
MBW?
@@rodefshalom MacBreak Weekly
Yes you are so missed
Rene missed the point in a few ways:
1. There are people who intentionally drain their battery everyday because they think that's better than just topping up. This is worse than topping up throughout the day. You mentioned that it's not bad to let your phone below 20%. Technically, that's false. It's best to top up during the day and not drop below 20% as much as possible.
2. There are a LOT (hundreds of millions) of people who do not have an Apple Store near them, especially in Europe and Asia, (especially hot parts of Asia) where managing the battery means a LOT more to them than the average American. My fiancè had 0 Apple Stores on her entire island. So for people like her, managing the battery is something that matters.
Unfortunately this video assumes that everyone has $70 to spend on an extra battery and lives near an Apple Store, when that's just not the case.
Sure, I live in the USA and have a lot of disposable income and can easily just buy a new iPhone if my battery health drops, but millions of people do not have that luxury, nor an Apple Store nearby.
That's a problem I've noticed with a LOT of Rene's videos.
But overall, I do agree most Americans should likely not worry too much about their battery health.
Even then as I live in the USA, the nearest Apple Store or Best Buy is over a mile away
I live in the philippines, its pretty hot here and original iphone batteries here are extremely expensive, more than 100 dollars. They will also ship your phone outside the country , i think in singapore so you will wait for a month just for a single battery. So i agree we need to micromanage our batteries here. I learn it the hard way when i neglect my 12 mini battery.
If only phones had easy to replace battery like the old days 🥲
I kept my iPhone 12 Pro's battery between 40 and 80 and it was still at 100% capacity after 18 months. I charged it "normally" for 6 months and lost 6% of the battery capacity.
I really very much doubt that a battery can be at 100% capacity after 18 months, no matter what someone does beyond just packing up the device and not using it for 18 months. (And even then I still don't think it would be at 100%.)
It could’ve been that the cell in your phone was quite a bit larger than the nominal capacity so you were initially burning through that extra. Also keeping the charge between 40 and 80 suggests that you didn’t use the phone much so you would’ve had less charge/discharge cycles
I have battery health at 83%, almost 4 years.
Not bad I think.
I got 86 percent in less then 1 year and a half
thats fantastic
I'm at ~80% on my XS (after 3years) but it gives me a warning message saying battery is in critical health and needs to be serviced. Battery burns really really fast. But I'm upgrading to the 14 Pro soon anways.
@@kt334 so does 80% health affect your phone performance too? How many hours does your phone last?
Same on a 11 pro max I got at launch so about 3 years
What phones are you using that have easily replaceable batteries? As far as I was aware pretty much all modern phones have their batteries hard-fixed to the motherboards. The battery is the deciding factor of when I'm going to get rid of a phone and I'm sure its that way for a lot of people too. Manufacturers would certainly be aware of this and holding onto the same phone for 6 or 7 years just doesn't cut it from a business standpoint when they know they can get the majority to swap phones every 2 to 3 years at least, so why try to eek more usable life out of the battery? I only charge with the slow charging from my computers USB port or the 12v charger in my car, if I plug it into the wall with the max power charger it gets uncomfortably hot.
7:40 Not to mention that wireless charging allows you not to have to deal with a port becoming loose or breaking over time.
Exactly, and with MagSafe and you can listen to music with wired headphones and charge it
users wanted it, and they got it. As convent as thing things have become, i'm not about to introduce problems myself..
And if i live in the 'stone-age'' then so be it
*picks up my club and i drag my sister into the cave*
I’ve had my iPhone 13 Pro Max since release day and it is still at 100% battery health, with moderate usage everyday. Compare that to my iPhone 11 Pro Max which lost well over 10% in its first year! Apples focus on improving battery health is showing
‘Battery capacity’ kinda feels like a lie to me. I’ve had an iPhone 11 for over 2 years it’s at 89% capacity but the battery performs really well with minimal use I can get well over 24 hours. Compare that to the phone XR my wife used to have her phone was draining much quicker while at a capacity of 95% or even a little more. That being said I never let my battery go under 40% before charging.
just upgraded from my 11 pro max and its battery dropped to 88 percent battery health relatively quickly but then kind of capped there
Don’t count on that % because sooner on later it will drop down to 99%
My normal used iphone 12 mini (that really is known for poor battery life) after 1.5 years is still at 100%. I do not know anyone who relies only on battery AI being able to achive this. And it is not that hard to achive this.
The battery percentage health is not accurate, it just calculates the cycle per charge you do then lessen the percent health by the numbers of cycles, so if you are a heavy user like playing heavy demanding games it will wear the battery much quicker and wont be directly proportional to the charge cycle because you drain your battery much faster. I compare same iphone models, one i used for work the other one for gaming and media, always charge both at night with almost same battery percentage. Same battery health right now 89 percent but the gaming iphone drains quicker when comparing just at youtube playback on both devices. The battery health percentage is just a rough estimation per charge cycle not the wear and tear of usage. Hope this helps to clarify :)
I have a iPhone Pro 13. I was leaving it on the with the MagSafe charger day and night. I noticed the phone was getting real hot at night. The first month it got down to 94% Battery Health. I switched back to cable and been charging it to around 80+ % for the past 6 or so months. Battery Health percent stayed at 94 ever since. I don't know if it was a software bug making it heat up or if my phone has a hardware bug or smt but I don't trust Apple's charging logic with this phone. I think iOS 16 has some new check for temperature check with when charging, might give it a go with this phone after I decide to buy a new one.
I used an inductive charger on the iPhone 13 Pro Max for a year, I was still at 98%. It's usually behavior, not charging, that affects stuff like that
This 1000 times, I gave my MagSafe away because of this my 12 pro max was at 86% after only one year…my fathers 12 pro max is at 98% after one year
@@ruialex314 well the usage, cables/bricks, and environmental temps all factor in. Before I upgrade my iPhone 12, I used MagSafe to charge for basically 98% of the time for about 2 years, and it’s now floating at 91% battery health.
@@CerberusTheWise I never had this problem with any phone and I stopped using the charger the battery didn’t go down anymore maybe 2% in one year
@@ReneRitchie However, it's not the same living in Utah than in Florida. Room temperature at night WILL be different, and then inductive charging builds upon that. I guess, at least.
I do have to say though that the primary use of MagSafe to charge my iPhone 12 Pro appeared to shred battery health much faster than I was accustomed to seeing, putting me down to 80-something percent in less than a year.
Same. Mix of magsafe and the 20W fast charger and my 12 PM battery doesn’t even last half a day anymore. I’m going back to the 5W charger for night use on the 14. Will bring faster chargers though for travel
Agreed. Went to 87% in ten months on my 12 mini, which already had limited battery life out of the gate. Magsafe kills batteries.
iPhone 13 pro battery at 350 cycles and 97% battery health, a few simple rules that don’t require micromanaging:
1) Try to charge before 20%
2) Enable optimized battery charging
3) Cool down the phone after intense heat. I love being out in the Texas heat, and my phone has felt plenty of it. I just put my phone in front of a fan for 2-3 minutes so that it’s cool to the touch
That’s it. I almost never use my phone while charging it either, since it’ll be up to 80% or more so quickly anyways.
Literally what I was looking for to confirm my steps that I’m going to do for my iPhone 14 promax, cheers mate.
@@ShadiFagihi cheers
I agree, the point of charging it from 20 to 80 is to save the battery health, but you're technically only using 60 percent of it which defeats the purpose of saving the battery as if you only have "60 percent batter health" remaining, seems way more complicated and stressful than to just replace the battery every few years
I went to Apple Store for replace new battery after one year uesd my iPhone 13 Pro,but they suggests me to change my habit or charge behavior instead change battery,but I insisted to changed new battery and now just like new phone 😆
Don't see the problem. The reason is to preserve as much of the 100% for the few days where you can't charge during the day. For normal days 60% should be more than enough as your going to be near the charger all the time anyways
@@KK-up3pq if 60 percent is enough for the day, then why put all the struggle to keep the battery health at '100 percent health' at all times? Doesn't makes sense to me
I agree. I got lots more things to focus 🧘♀️ with life than my phone’s battery health. With my workflow I end up charging my iPhone and iPad Pro 2-3 full cycles every day of the week due to the photo shoots and editing runs I do. I could leave them both plugged in when inside the office, but I just charge them during my 30-60 minute breaks in between work.
@@yabibiin find an Apple Authorized repair center. You won’t have to wait as long and they won’t argue about it with you. I’ve replaced batteries that were between 90-95% capacity as I was noticing the change in how long it would last the day, and never have had any gruff about it. If they don’t want your money a 3rd party store will be glad to have your business.
About 3 years ago my dad bought xs max and two months later I bought 11 pro max, I micomanaged my battery and my dad used to leave his phone plugged overnight and whenever he felt like it. Half a year later my phone seemed to keep 100% battery health and my dads phone dropped to 95%… but now 2 and half years later mine is 83% and his 87%, considering we have same level of use, and the fact i was constantly worried about my battery health causing me to use only 60% of it (20-80%), I now realize it wasn’t worth it.
I have a random wake up scheduled. This doesn’t work for me.
I have had many iPhones over the years. Even with the faster charging, I still use the 5W charger. Every one of my phones when I either sold or traded them, all had 100% battery. Merely throwing it out there for you.
I don’t care what anyone says, going slow is always easier on batteries.
@@JAMESWUERTELE My years of doing it that way have proven it so. I have many friends that use fast chargers. Within approximately 1 to 1-1/2 years, their batteries are at 90% or below. Hard to argue with facts.
@@herb601 depends on the phone I guess. I fast charged my one plus 7t every day for three years and it just hit 80% battery health.
@@robbennett The Chinese OEMs have some excellent battery tech, like OPPO, they can charge 1600 times before they reach 80% capacity, whereas the iPhone and Samsung it is nearer 500 total charges. Also, they split the battery so that 60-watt charging is more like 25 watts per battery half.
How many charge cycles do you have? I’m a power-user, using 120-150% of battery per day. Only charging with 5W charger over night but having 400+ cycles per year makes me lose about 8% of capacity per year. And I don’t do gaming, my phone doesn’t get hot often.
My iPhone 7 is sitting at 86% Battery Health with 825 cycles on a 4 year old battery and I've been using a smart battery case on it the whole time. Most of the day it sits at 100% charge all day and only drops to maybe 80% by the end of the day on the internal battery. I don't worry about the battery and it has been perfectly fine!
I tried micromanaging my battery on my iPhone 13 Pro and that somehow caused the battery health to drop to 99% literally less than a month after I bought the phone. I’ll be taking Rene’s advice with my 14 Pro when it arrives later this month. I guess it really is best to just let the phone take care of itself.
the advertised mAh is what the phone sees as 100% so if your battery happens to come with slightly more at max charge then that is why you would see 100% for longer, it doesnt really mean anything, so yeah dont worry and just enjoy your phone
when you feel the need to mention that you're getting a 14 pro
I’m waiting on my 14PM space black. REEEEEEEEEEEEEEEEEEEEE
@@lllhunterlll9644 I have about 380 cycles on my iPhone X (according to CoconutBattery, not sure how accurate it truly is), and its at 98% battery health
Lol. 15 ultra max is almost here.
My 13 pro max always charged it to 100% and sometimes leave on charger unless I go out. And it’s 98% charging capacity after a year. Rene is right. Let the tech do it’s job for you…
I found out after three years and over 800 charge cycles on my iPhone 11 Pro battery, a quick trip to my local Apple store and about $70 got me a fresh battery installed with 0 charge cycles. Would recommend over getting a new phone based on prior phone's battery life.
The 6 month old 13 Pro I just sold, still had 100% battery health. I didn’t do anything special and didn’t babysit the charging or the battery in the slightest. I fast charged whenever and wherever I wanted, when it was dead and overnight, 95% of the time with MagSafe. I must’ve had a great battery?
the only thing ive been doing wrong all these years is leaving my phone plugged in at 100% just so it’s always ready to go
This is one of the reason I did not turn on battery percentage on on my 13 pro max. I gotten so used to not seeing a percent that when I turned it on. And watched it go down it started to give me anxiety. So I just switched it off and just enjoy the phone and it’s amazing battery
Hahahah dude tffff … i did the same tooooo because of same reason 😂😂😂
I’ve had an iPhone 13 Pro since October of last year, and I’m at 91% battery health. The problem that I deal with is that Apple doesn’t really let YOU decide when and where to charge your battery up to 80 and then go up from there, it decides for itself using machine learning.
I’m a college student that has late nights (or all nighters) working on assignments, and other nights where I fall asleep at 8:00 PM. My iPhone just can’t decide on what my schedule is because *I* can’t decide what my schedule is. So because of the way they designed it, my battery gets zapped into charging full every night in an hour or two, and then is on the charger all night. I really wish they would base it off of your sleep schedule set in Health rather than the presumed schedule they think you’re on, because I don’t always go to sleep at the same time, but I always wake up at the same time. I hope Apple adds this feature in later that allows you to base charging speed/percentages on when your alarm is set for, rather than just an estimate.
It is based upon your sleep schedule dude
@@pureluck8767 According to Apple's own site, "With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged. When the feature is enabled, your iPhone will delay charging past 80% in certain situations. Your iPhone uses on-device machine learning to learn your daily charging routine so that Optimized Battery Charging activates only when your iPhone predicts it will be connected to a charger for an extended period of time. The algorithm aims to ensure that your iPhone is still fully charged when unplugged." Now I will say, when it does engage, it will indeed schedule charging to finish by the time my alarm is set, however it almost never engages as stated for the reasoning above, since my schedule is never consistent. I really just want them to add a feature that says something like, "Between x time and y time, turn on Optimized Charging whenever connected to a charger." That would benefit me greatly, especially since my battery health is getting lower every day
It might sound dumb but get a 5 watt apple charger. I use two apple chargers one 20 watt and one 5 watt. I use the 5 watt to charge overnight cause I don’t need the faster charging speeds when I’m sleeping and use the 20 watt wherever I have to juice it up quickly throughout the day or before heading out for a hike or sth
Spent last two years of my life struggling to keep my iPhone and iPad at below 80% I’m done with stress. My phone is at 92% health my sisters is around 90% and she didn’t do any of that. New Mac chargers so fast I can’t catch it before it gets to 100. I’m just going enjoy my stuff and replace barriers via apple care when needed
I agree with everything except in part with wireless charging. Wireless does generate quite a bit of heat, and while there are solutions for fast wired charging there is not much can that can be done for wireless. But if it's convenient for the user, it's a worthy trade-off...
Another thing that should be pointed out is that this applies to iPhones but not to iPads, which don't have battery optimization. Also Android phones don't always have it either (Samsung does) and worst, most Android OEMs do not offer battery servicing...
You're very much mistaken about modern Android phones not having the same smart Battery Technology. Adaptive battery, adaptive charging was on Android long before iOS
What about first charge?
@@michaelcorcoran8768 you are saying I am mistaken about something I didn't say.... I never said that modern Android phones don't have adaptive battery for instance. Also when I said battery optimization I meant more than just adapting charging. Adaptive charging works well when you have regular charge habits, but does not work so well when you don't... Samsung phones for instance offer a battery limit of 85% which allows you to leave the phone plugged it any time for any lenght of time. Regadless I din't say that most brands don't have adaptive charging, just that some don't (most actually do today). Nor did I say it came on iOS before Android...
I'll keep saying it. I've kept my iPhone 13 pro max between 40-80 for the last year, when I sold it, it was still on 100. That definitely increased the value when selling.
But the 13 haven’t even been out long enough for it to degrade below 90-100% anyways so that’s no surprise at all
@@BIG2hats there are people who have shown their battery health status at 95 and below.
my Iphone 12 pro battery went from 99% health to 90% health in 4 months, when should i charge it ? i charge 20-100 or less than 20-100, any tips?
Even though iPhone is my primary device, I bought a S22 Plus recently to play around with Samsung just makes battery management easier, they gave you a setting to pause charging at 85%, so you can charge anytime and not have to worry. You can easily toggle this setting on or off from notification quick controls. Of course Apple refuses to give us control over anything like we are idiots or something. It’s not about 70 bucks battery replacement costs, it’s about using this planet’s resources wisely, it’s a lot of resources to make these batteries, let’s make the best of it.
This is also how EVs work, you set a daily charging limit and then if you need to go on long road trips, you can change it to 100%.
I had my iPhone 11 Pro Max on 100% for over a year, I use 2 Apple Smart Battery cases, once one case dies I switch to the other case, the case gets swapped at 1 percent, it’s died on me a couple times which made me use the phones battery a couple of times
Just program a battery replacement at two years if you plan to ķeep the phone long term. That works as well as any scheme I've come up with to baby the battery.
Or buy any other phone than apple. Problem solved.
@@redsai666 true haha. Why are apples batteries so bad?? 🤔
My phone batteries never last more than 2 years.
Never bothered to replace them. Just get a new phone.
I don’t believe this, I would charge my iPhone 12 Pro Max overnight and within a year and a half the battery health was at 80%. The smart charging and artificial charging does not work as well as people think it does, it just doesn’t
The feature that phone learns when to stop at 80% and wait till you use to charge to 100, you have to plug in at the same time for 5-7 days straight for the phone to learn your charging habit. If you switch everyday, your phone can't learn since there is no pattern. if this is the feature you talk about,.
You're wrong because neural networks, algorithms, machine learning, artificial intelligence and other buzzwords!!! Lol no the battery chemistry is still there and no fancy words are going to change that. Micromanaging is just not worth the time in my opinion.
I just sold my iPhone 11 Pro Max and I always charged it whenever and however I wanted, the battery was still at peak performance and this is a four year old iPhone.
Why can't they charge the phone until 99%, and keep it there, and call that 100%? Like the reverse of 0% not being 0%?
2 yrs on iphone 12 pro max and battery still at 100%.
Use 6 hrs a day on an average both with & without charging cable.
Phone is jailbroken - so have a tweak which stops battery charging once the cell’s battery hits 80%.
double r. please tell us why apple didn't include their vapor cooling system for their i phone 13 14 etc to help with the battery from overheating?
I rocked an iPhone SE (2016) all these years until last week (not a money issue). The battery health was still saying 90% but i knew it was f00bared. It rebooted on random occasions (voltage drops), and the % dropped just by if you stared the screen funnily LOL. Sure, i could have still replaced the battery but the phone itself was around 10 dollars worth and no more updates after IOS 15. Bite the bullet and finally upgraded to a iPhone 14 Pro few days ago. Talk about milking the last drop of your tech before upgrading. The leap with this upgrade has been magical 🤓
For those who know your car stuff, micromanaging iPhone charging is a bit like lifting up the throttle in manual mode of an automatic car
well... that didn't work out.. most people have automatic cars these days... Manual cars are dying like VHS tapes
@@Tech-geeky hence the comparison to an automatic car
Rumor says that using the phone outside when it’s over 35 degree Celsius will ruin the battery, is that true?
Great video Rene. Always been impressed by your tech content. I 1000% agree. I don’t know why people obsess over battery health. iPhone batteries are $100 or less to replace through Apple & if you have AppleCare + then it’s free when the battery wears down. It’s going to happen. People spend more time babysitting their battery than actually enjoying the device. There are a few common sense things people can do. Don’t leave your phone in extreme heat or extreme cold, use official chargers and I would say don’t run the phone below 20% often and you should be fine. People think because the battery wears out that’s the end of their iPhone when that’s not the case, just get it replaced when that happens.
The problem is apple only replaces battery at 79% or below. There are so many posts on Reddit saying that they won’t do it. Even if you want to pay for it. Then you are stuck at 81% or 80% battery health.
@The Omniverse apple even won't change the battery for a 4 yrs X's Max, so why people bother buying their trash when newer iOS is all about anti third party repair which will disable the battery health. So what's the use of buying iPhones, that are borderline unfixable and you have to throw it in the trash when the battery will die or the phone is permanently bricked creating more e waste???
does opening the phone reduce its water-resistance? do they seal it properly?
They don't even sell batteries for most Android phones.
I've learned customizing your lock screen drains the battery like crazy.
Don’t go lower than a quarter tank. The fuel keeps the fuel pump cooler. So they last a lot longer. 😊
Thanks!
Thanks so much!
LOL You got everyone with that 80% explanation!!! "If you only use it to 80% anyway, why would it matter if battery capacity drops to 80%??" logic, my man. 🧐
I got a brandnew Iphone 14 Pro max and i fell asleep last night and leave it charging for almost 5hrs. Will it damage the battery?
So why does Apple MagSafe battery keep you at 100% and previously their Smart Battery Cases also keep you at 100% for ages, case also generating a lot of heat!
Battery health: does it matter for battery health whether you charge with a 20w adapter, 60w adapter, or 10w wireless thing? Also, is it bad to leave it on a wireless charging stand all day (even when fully charged) ? Thanks.
Whats wierd is I never thought "Battery health" worked.. Perhaps on the latest iOS AND iPhones but not when using iOS 15 on older ones.
My battery health on my iPhone 6s Plus, still shows *100* optimal, yet i know i keep charging my phone regularly than two times a week..
I'm a light user, so under normal circumstances i could go a week and a half without a charge.. Since the iOS15 update, I' been having to charge much more, even though my habits have not changed, and the phone thinks its still "optimal"
Because my 13 pro max has such long battery life I don’t charge it at night but random times throughout the week. Because of this my phone is never charged to 100%, usually 90-95% is when I will pull it off the charger and I’m still at 97% battery capacity a year later.
Multiple government studies have shown that staying between say, 40-60% can have a standard battery last millions of cycles, literally. Most of those side effects are due to charging/discharging at extremes.
But yes, keeping your battery relatively cool is probably the most important for a smartphone.
Millions? Highly doubt that, if that were the case it would be more well known and used

@@monsterous289 long term sats wouldn’t use millions of cycles though. Keen to read some papers when you can let me know the titles, I know you can get thousands of cycles, millions with current tech just doesn’t seem right to me
Umm what if electricity goes.. fully charging a battery pack is d best option if you wanna leave phone batt settings on to save it
Whenever I wirelessly charge my phone I have it hooked to a AC vent in my truck which keeps it cool and makes charging faster. Accu battery helps me monitor the temperature and charging status.
Just got my iPhone 14 pro and I’m actually shocked how terrible the battery life is. I don’t know if there is something wrong with it but it’s barely making a full day. And I’m not a heavy user at all. Even over night it loses 15-20%. Even though all the background things are turned off.
that is not normal at all, stock ios or did you update? happened to my 13pro after i first updated[15to15.5]. u.s device using it in turkey. so i just sold it.
I’d def return that. I’ve only been charging mine once the night before and it lasts until the next night.
My iPhone 12 Pro went to 99% after one week, over the next 11 months it dropped to 89%…it’s been at 89% for 13 months now and lasts exactly as long as it did the day I bought it.
Battery capacity is a mystery. Doesn’t seem to translate to performance.
You must be a power user
what about heat over time from fast charging? my iphone 13 pro gets uncomfortably warm when charging on the 20 watt adapter and heat is a universal no no for batteries.
Been wondering this as well
Miss your reviews Rene, hope you’re enjoying your new phone and new job!
This video was the best explains on this topic I’ve seen regarding call phones specifically. A+++
Don’t agree completely. Sure, it’s true. I still avoid charging to 100% when I don’t need that much runtime. What was just wrong was the ‘wear leveling’ part. That can’t be done in a battery. Maybe you mixed it up with an SSD. But cycling the battery between 60 and 80% doesn’t hurt it anyway.
Cold absolutely kills li-ion batteries. Check your facts on that one.
He didn't answer the biggest question of all: Is it ok to leave my phone on the charger, even if its up to 100% for hours?
He says it at beginning of the video, it's OK to charge to 100% but don't leave it there for long periods of time, because that will put strain on your phone.
How exactly is the BMS going to use a different 20% of the battery each time if there is only 1 cell in the typical phone?
The $ over the life of battery being minuscule makes sense but honestly it’s the hassle of having to bring it in to apple and the constant power anxiety at the end of a battery’s life that bothers me more so than the cost.
I only charge to 80% because it charges slower & discharges faster from 80-100%. And because I like to dock my phone when I'm just sitting down.
I’m 9 months in on my 13 PMax and I’m still at 100% health. My battery is typically at 45% when I plug it for the night from being used off and on 12:30am to 7pm. With the great battery I only charge it when I’m asleep. I absolutely love my iPhone 13 Pro Max ❤❤
99% almost made it a year lol
I remember a while back you made a similar video, maybe about the MacBook Pro and I have kept that advise. Actually my M1 work laptop is charging at home to 80% and once I don't charge it and let it drain for a few days it will send the message to plugin and I do it and it takes it to 100% so it is smart as a whip. My iPhone 11 still goes strong as well. I know that after 80% it is maybe shorter but who cares, there are outlets everywhere, except when you need them of course.
The optimization never works for me. I go days on one charge. So when I charge it is irregular so with no pattern it just always charges to 100%. I usually catch it at 92-95 and at that point why not just let it finish
I have a 12 pro max and at 81% battery health. I use MagSafe and I charge over night. When I charge at work and I put it in front of my fan. I try to keep the phone cool when charging now. I think I’ll stop charging over night unless it’s below 30%
I don't baby my battery, but I am mindful. I don't uselessly charge from 0% to 100%. I usually end my day with 15% and then charge to 85%, then 100% during my morning routine. Any top up charge I do is usually only up to 80% it charges the fastest. After just over 1 year (14 months) my health is at 96%
Same. You don't need to do any of those shenanigans. Use your phone at will. Enjoy it. You can always buy a new battery or pass it on to a family member when you bought a new phone
I’ve constantly charged an iPhone for 5 years straight and the battery life hasn’t changed in any significant way.
I can’ believe any of this concerns anyone.
Does wireless charging affect the battery life??????? Please suggest.
Awesome video. My main question tho is if the 20W charger damages battery health overtime, simply because every single time i charge my iphone with the 20W charger (just went from XS to 14 pro max), my phone gets quite hot, even if i unplug it when it reaches 100%. it’s also weird that the 14 pro max came with the usb c cable, so 14 users that don’t have a charger yet have to buy a 20W adapter if they wanna stick with apple’s first party charging blocks. for now i’m sticking with the safest route i know which is apple’s 5W port and USB-A cable.
5w is definitely safest to minimize temps
Very helpful and that was an elegant transition to your sponsor….at the end. Well done.
My XS Max is 4 years old and the battery health is at 92%. I don’t deep cycle it very often. I usually keep it charged at work and at home. I rarely have it go below 50%.
Thanks! How about iPad 9th Generation charging? Can I leave it in the charger all week as it is used to run an audio mixer at church. Should I unplug it after it’s charged?
What about having your iPhone on low power mode all the time compared to not having it on all the time?
You are saving maybe 15% per charge cycle
why then many used iPhone 13 pro on used market sale are 80-90 % health battery and mine is 100% after nearly one year ? :-) I would not worry too much, but keeping it between 30-80% most of the time worked for me. :-)
Replacing battery should be a habit just like changing tyres. If it's worn, just replace it.
I live off grid and use lithium batteries as a reserve of power as a result I know a fair bit about them
What this bloke says about batteries getting above 80% is correct it's leaving them there for extended periods of time which causes the damage and as most people will charge overnight to 100% and then use it this causes very little degradation in the battery
The big thing is letting them get below 20%
If you get home from work and are on 30% for example and only charge to say 50% before going out again this is far far better and what you should do rarther than carrying on with your day and letting it get down below 20%
I was literally wondering about this question just yesterday about whether I should care about my charging approach. On my old iPhone X, I had the same battery for 3.75 years and used the phone for 5-7 hrs/day according to my activity charts, routinely charging to 90-100%. I was surprised it lasted that long but I also charged wirelessly 90% of the time so the phone was rarely hot, so I think that played a role in how long the battery lasted before my iPhone 14 came.
I think micromanaging it is a waste. You're basically enduring the kind of limitations that you're trying to prevent. And it's possible they won't even help
Are you serious? I let my iPhone X run down completely and then charge overnight to 100%. I’ve been doing this for years and guess what? No problem. Who has the time to worry about charging until this or charging until that. Give me a break
iPhone battery replacements are so cheap and quick now, that it just makes no sense thinking about batteries at all, even if you are burning through them every two years. Imagine if we could use our cars heavily for two to three years, and the only maintenance we needed to do was a $50 component swap. Heck, I saw a reddit post yesterday of a guy still rocking an iPhone 3G from 2008 as his daily driver still. Even after the battery is worn, the device will likely still work.
Is it bad for the batteries to keep my iPad Pro 12.9” gen 6 & M1 MacBook Air plugged in 24/7?
Or keeping my iPhone 13 Pro Max plugged in all night while I sleep?
Your stressing your battery way too hard, just top up whenever…
I can get 40 hours between charges on the iPhone 13 Pro Max without low battery mode.
If apple just gave us one setting the battery would last years longer. That magical setting? Set the max charge to 80% or 90%. This is what Tesla does and as a result the battery in the car lasts many years. Not just two which is the apple goal. Adding the machine learning on top of this is great, like Tesla does. So why does Apple not give us that simple setting? So the battery will wear out and you will get a new phone.
@01:12 an 80% charge on a 100% healthy battery works better than a 100% charge on an 80% healthy battery. They are NOT equivalent. Unhealthy batteries have higher internal resistance, which means that they get hotter when discharging and charging and are unable to provide as much power when their charge is lower, causing a phone with a weak battery to suddenly go from 15% charged to zero when running high demand apps.
13 pro max, mine says 92% health. I only charge it nighttime on my magsafe stand with optimized on. I'm not sure what I'm doing wrong.
Same here. 13 pro max I purchased in April of 2022 and I’m at 94%. I’m going to try turning off battery optimization and see what happens.
But I am seeing charge on hold due to iPhone temperature on ios 16 on iPhone 13 pro while I do not see it heating up at all. How do I fix this?
Update: A hard reset fixed my issue. If it doesn't in first attempt, it will in second attempt :P. While connected to charger, I hard reset my iPhone.
My 13 Pro Max is still at 100% capacity because I don’t charge it overnight and often don’t need to charge it everyday. I just charge my phone when I need to and avoid doing it overnight so it isn’t going from 99 to 100 constantly back and forth while I sleep.
20w charger?
The sponsorship plug was smoother than the Dynamic Island's animation 🔥
I try to stay between 40-80 but if I go above or below, I don’t freak out. I just want to keep the battery as healthy as possible
Wireless charging is the only charging that could produce a bit more heat. However with official chargers, I have never experienced excess heat. Also do not care about battery health. It is cost-efficient to simply not care and replace the battery when needed
I agree, I just plug it in and let the phone sort it out.
I really need answer : I like to turn off iphone every night at 100% charged, is it ok or not?
Theory; I think that users that don't micromanage have fewer cycles registered as a result (as sometimes these use it whist it charges/charged), but could have more damage for real health.
I've been micromanaging to a crazy level, keeping it between 65-75% at all times. But unsure if any benefit to it. I agree that heat is half of the culprit of the wear, and charging causes heat. For me the jury is out as to what is best practice.
My 13 pro max which I’ve had since launch is still at 100% Battery health! All I do is wirelessly charge every night when I sleep and that’s it! And I’m now doing the same with my 14 pro max!
What kind of wireless charger do you ise?
@@ShadiFagihi I use apples MagSafe Duo Charger
Same here!
1:00 fair point. I never thought of it like that. Only argument would be for that occasional need to have 81+%… but that is weak.
If you change the iPhone battery after a year or two . The battery performance will be significantly low than it was first bought. For example my iPhone 13 was bought one year ago and battery now is at 90%. If change the battery now from apple. After a year it will be less than 85%.
iPhone 11, fast charge everyday for 3 years, heavy gamer (play game while charging), battery life now 87%.
MagSafe does seem to overheat my phone.
Hi! Great info thanks 🙏 very reassuring 😄And how does this apply to MacBooks? Should you work with a MacBook plugged in? Does it damage the battery to have it working at 100% all day, every day? Is it better to have a higher cycle-count with less 100%-mileage, or far more 100%-mileage and a really low cycle-count? And, if you do work with the MacBook plugged in, does Apple itself recommend imposing any kind of discharge routine/schedule?? 🙏
Same question especially because I’ve got the Studio Monitor and because it’s always plugged in to my M1 MBPro. In addition I’m using a hub that’s powered in order to get Ethernet soooo as a result my MBPro is “always charging. Will this hurt my MB? What do you suggest?
Same question
Thanks…I appreciate your thoughts on battery charging. Blessings on your day!
Yeah phones have had some form of “smart” charging since lithium ion batteries first showed up. I had a Motorola Startac back in 1998 and one of it’s selling features was smart charging, which at the time just meant the phone managed it for you so it would not over charge. This was required with those batteries to prevent them from overheating and potentially exploding. Now as Rene explains it’s all fancy and uses machine learning for optimal charging, but basically you haven’t really had to worry about it that much for over 20 years now.
