I can't believe the 5W block is very hot; it could've started a fire if kept plugged in. If I used that for my iPad Pro, that power block would blow up and start a fire. It's not worth using a 5W block charger. Newer iPhones, both regular and the pro models, even the iPad and the pro models, need to be higher in watts of power thanks to how powerful the components are.
For the rest of us 🇬🇧 🇪🇺 viewers in the world 🌍 who are not living in the U.S. and use the metric system for measurement, the temperature conversions (which should've been included in the video but weren't) for the phone Vs block charts are as follows: Phone Block 114*F = 45.6*C 96*F = 35.6*C 107*F = 41.7*C 99*F = 37.2*C 96*F = 35.6*C 125*F = 51.7*C 94*F = 34.4*C 160*F = 71.1*C
As a electrical engineer i know Lithium Ion/Polymer batteries dont like more than 1C charging speed. My iPhone 12 Mini had about 8-9Wh battery, the 5W brick, giving about 4,8-5,2W needed about 2 hours for 100%, charging speed of about 0,5-0,6C, perfect for longevity and this battery has after 600 cycles and 3 years still 89% health. With the iPhone 15 5W became too slow, nearly 2x the battery capacity means instead of 2 hours charging 4 hours which is bad. Just for fun i started the 20 Minute 3DMark stress test with even low brightness and tried if the 5W charger can still charge... NOPE, battery drains on the iPhone 15 with 5W under heavy load. 5W or "super slow charging" is really not recommended anymore, and you should realise this as end user when your phone charges for 4+ hours for a full charge. Just when it comes to wireless charging... i avoid it as good as possible except in the car where Magsafe is not only the "clamp mechanism" but also a nice way to get some power for navigation or so. When i refer to "fast charging"... its 10, maximum 15W on a iPhone, 30W on the iPad and 65-140W on my 16" MacBook Pro. Regular charging speeds are for me: iPhone 12 Mini 5W, iPhone 15 9 - 12W. iPad Air 5 (M1): 20W (perfect speed, yet a barely warm device!) 16" MacBook Pro: 20W (iPad/iPhone brick), mobile 45W brick or a 65W, 100Wh Powerbank, powerbank mostly just to avoid using the MacBook battery under heavy, sustained load on the go which is like 3-4 hours heavy processing performance just out of the powerbank
I have a 5W and 20W iPad Pro charger at home. My charging blocks don’t seem to heat up that much - so I’m not sure why your 5W brick did. However, my phone stays stone cold on 5W charging while it how generate some heat with 20W or wireless charging. That’s why still plug in my phone with a 5W brick overnight and at the office for topping up. But I use only my MacBook/iPad Pro charger to charge my iPhone when I travel.
Whenever I search things in regards to Apple on RUclips I'm always so relieved to see that Brandon's covered said things. It save me having to sift through a sea of mediocre content creators, each of whom tell me different things, makes it difficult to know what's true or not. With Brandon you get top quality information that you can trust. 10/10
Using percentages to describe differences in percentages is a big no no. That’s what basis points are for. Saying 32% is 28% higher than 4% is completely wrong.
MagSafe Duo as previously noted. Might be interesting to see how MagSafe chargers compare ( including non-Apple-branded MagSafe chargers like the new nightstand models. Thanks Brandon.
It would have been better to have a higher wattage charger in the mix since your data shows that none of the chargers are the max advertised speeds. At the very least have a 45w charger to be able to showcase the actual max wattage pulled by the iPhone in a situation where it will have the headroom to do so.
@@BrandonButch If you care to extend the experiments I have a few suggestions: Measure the total energy consumption for the chargers. Running a block for 5:44 at up to 160° sounds pretty wasteful. Also add a MagSafe charger to the list.
Hi Brandon, very interesting video. I just wanted to say that it would be awesome to include temperatures in C° as well for your non American viewers. Keep up the great work
@@kofidrng One is based off of how water feels, one is based off of how people feel. So considering that we are people, which system should we use? Maybe the one designed for humans?
@@heinzketchup3323 Why don't you use binary? It is the best numbering system based on science. But it doesn't work for humans so we use base ten instead. Fahrenheit is better because it is designed to work with humans in humans daily lives, just like base ten. If you think metric is better you should stop using base ten and use binary instead, binary as based in science, base ten is not.
It would be great to see a video showing the comparison of popular 3rd party chargers compared the same way to the Apple charger. And also a video comparing the Apple cable to 3rd party cables in charging.
Every new iPhone I have used with the 20W Apple Charger, it makes my battery health go to 90% within 6 months after buying the iPhone brand new. Switched back to the 12W iPad charger, and my 14 Pro Max is at 98% battery health after 8 months.
I've been using an Apple 5W charger for years for overnight charging, but seeing this I think I'll switch it out for a 12W Apple charger that I still have but don't use for anything. Thanks for the info!
I've been a big fan of trickle (5W) charging overnight for my phones, it's not scientific but my 2 and 3 year battery health percentages have never dropped below 97% and 94% respectfully using this method. Same company phones (2 year old 13 Pro Maxs) using MagSafe and 30W chargers are 89% and 88%.
Yes, 5 and 12 watts will run cooler temps on the phone, but the phone will hot during charging for 5 hours, where as using 20 or 30 watt will reduce the charging time which means your phone will be hot less amount time even though the temp will be higher
@@Danik.iceman entonces que es mejor? cargar a 5w durante mas horas y menos calor pero mas tiempo o cargar con el de 20w con el cable trenzado menos tiempo y mas calor? nadie deja nada en conclusion
Interesting to see the difference between phone temp versus block temp. I’d be curious to see a comparison of total power draw from the wall (like with a kill-a-watt) for each charger type.
I have a 20W charger, I wish there was a way to set the charger on lower wattage... sounds stupid I know. I have had androids before with fast charging capabilities and honestly I never used them, because I had no need for it. Even with 20watts, that iPhone 15 I have charges up pretty quickly.
I have been using an Anker Nano II 30W for my 14 Pro for one year now. I never use magsafe and never charge it overnight but only at breakfast or in the evening. I start charging at 30-35% till it's at 80-90%, sometimes 100%, and still got 100% battery health. My charging behaviour was the same with my P30 Pro (45W charger) and I couldn't notice any significant difference in battery life after 3,5 years. I don't play games on my phone though, might be a factor for faster degrading batteries, don't know.
Playing games makes your phone slightly hotter and drains your battery faster, thus makes you charge your phone more than once a day and will consume the battery health.
Interesting Video. Thank you for this. Do you have any plans to redo the test using the charging optimization? I'm curious to see if the slight difference between the 20w and 30w is negated from the apple optimization.
turning off the charging optimization wont do anything if the iphone is new and also if you take care of the battery( taking your phone off the charger immediately after it gets to 100 percent everytime).
Could it be you had defective 5w charger? I have used 5w with iPhone 11 Pro Max for several years and it really helped to prolong battery health. Or is really 15 pro max taking so much more power? It’s always funny when testers make those long faces about long time charging cause I don’t really care because I always charge at night and I usually sleep at least 7-8 hours. How it is so hard to understand? I only need fast charge during day but that hardly happens. The longer the battery health lasts the better. Anything else is not important.
Get 20w, less heat, charges fast enough... Just charge it when you go to bed and you will wake it with it fully charged, or even get a 10w charger tbh if you wanna do that
For the health of the battery is better to have a slightly minor charging temperature but for more time (12w) or higher temperature but for half of the time (20w)?
It would be interesting if you found a way to keep the phones cool during the fast charging to see if it would make the 30W pull ahead. I wonder if the increased temperature caused Apple to throttle how many watts it was pulling.
Wow ok, so anything above 30C / 86F is too hot according to some researchers, to avoid battery degradation. So to me, I want to ensure I'm using the lowest charging wattage possible, at all times, and the phone has a way to cool off, I'm hoping for the 16 series this is improved with the new battery casing
20W charging plug either with direct cable or Apple MagSafe both of which superheated my 15 Pro. So for overnight I switched back to Apple 5w charging plug and it is naturally cooler.
I loved how he has shown all the graphs of temperature, wattage & more. I try to use 5W to keep my phone cool at night but this video showed me how hot the block gets. I’m going to move to the 12W now. Thanks!
@@LouieSwagGWUORplenty fast enough from me, went from a normal Qi wireless charger with 7.5w which was fine to a Apple official MagSafe with 15w and I was pleasantly surprised how much faster it is. It’ll be a very rare occurrence that I need anything faster than that and for that moment I have a 29w usb c for my iPad Pro I can use.
I’ve been using an Apple five block for my daily charging with every iPhone every single year since 2010 love using it with my 15 pro max I hand down my iPhone to a family member each and every year and they hand it down to another family member. I have people using my Apple devices that I pre-ordered way back in 2014 and they’re on their original battery.
Very interesting test ! 👌 I use also 20 W for my iPhone 13 Pro Max and I was looking for the best option for my new iphone 15 Pro Max. I think I will continue charging with the 20W Apple block charger.
just what i felt through my hands the results are as i expected. The best slow charger is the 12w ipad charger for new iphones. I love these. Literally in summer still keeps my phone cool, but the 20w is the one that gets it too hot in summer.
I would like to see a test where the phone is being used while charging. I’ve seen the phone pull as much as 27 W when being used. That’s where using the 30 W charger makes the most difference.
Good video Brandon. But I don’t believe a 5 watt charger will ever put you at risk of fire as long as it isn’t damaged and the wall outlet or surge protector isn’t damaged. 160 degrees is hot but not hot enough to set fire to a carpet/wood floor/ blankets/paper etc. Those 5 watt chargers have been around for over decade and a half. Never heard of widespread fires. Just my 2 cents
Great comparison and analysis… clear and really like it. Just to share my experience: i did mine for iphone 15 promax, from 0% - 100% (using 20w) only took 101 minutes.
Very interesting test. It would be also interesting to check how much energy is actually used overall as it is liikely that the 5W charger is using as many Wh as the 12W, just that a lot of it is wasted in the 5W charger, which would explain the heat.
Try sticking a black, matte electric tape to the screen or back of the phone. These kind of thermal cameras will pick up heat from the reflections, @4:40 you can clearly see the heatspots are the reflections from your hands and the phone which captures the image.Ű Sticking a non reflective tape will prevent this anomaly.
I used to work in a company that designed a charger control chip that basically speaks to the battery charge control unit in the phone and let me tell you that it much more complicated than just plugging it in and pumping current into the massive capacitor (battery). Interesting to see the 5W supply heating the socket to 160F - Wonder what current the charger itself was taking in from the mains. Perhaps you could have had them plugged into smart sockets to illustrate how much power the charger was actually consuming to deliver the output to the battery.
Power supplies normally have a TDP matching highest rated power delivery but run more efficiently when not maxed out. A 45 watt PD brick would run much cooler than a 30 watt one if both were supplying 27 watts to the iPhone. When the 5 watt brick first came out devices probably didn’t pull 5 watts the entire charge time but a current phone probably pulls that the whole time since battery technology has evolved to stay cooler.
Perhaps his 5W charger was already aged/damaged too heavy. So if, he could show at best that you better replace your chargers here and then when the components aged too much and they get inefficient and hot. My 5W iPhone charging brick from like iPhone 5/6 times barely gets warm, as it has to be, considering they have about 80-90% efficiency (so MAXIMUM 1W heat output) Its also sad, but i dont have any use for the 5W brick anymore since i changed from iPhone 12 Mini (8Wh) to 15 (13Wh), the longer charging time on the iPhone 15 is horrendous with 5W (about 2 vs 4 Hours for 0-100%). But newer iPhones i exclusively (if possible) i charge with something slower than 15W. A Samsung fast charging brick charges my iPhone 15 with about 5V and 2.1A for 10W, 10W is at least for the iPhone 15 (no Plus or Pro Max) a sweet spot of usable "fast" charging speed AND barely noticeable warming up.
I've used 5W charger for 13PM, 14PM before and now using it for 15PM too. I got the 20W charger too, which I use only when I'm in a hurry. The point is, I don't see my 5W charger getting that hot like you've shown here, never. And I can confirm from my experience, using a 5W other than the 20W makes a difference for the battery health in the long run, pretty big one actually.
After having a iPhone 8+ with 87% battery health after 5.5 years, I only use the 5W charger now for my 14. The battery level remains higher through the day compared to when I was using the 20W charger.
temperatures higher than 35 degrees are bad for battery (apple info). So it's a good idea to use 12w brick at least during overnight charging which provide better battery health along with 80% limit option turned on. Good thing if you don't wanna 88% of battery health after one year usage as in 14 iphone lineup. On a mac I use AlDente app and it stops charging as temp hits 35. I'm stiil at 100% battery health after one year
I use 5W charger, typically top up 30ish-80% every morning at my desk while I work. I have used 12W USB-A charger when I'm in a bigger hurry and when plugged into my trick. I have only used 20W USB-C charging a handful of times when time was of the essence. Currently at 98% battery health on a 14PM bought two weeks after launch. I want Apple to bring the 80% charge limit feature to at least the iPhone 14!
I also noticed that I got slower charging with the 12w charger with my iPhone 15 Pro compared to my old iPhone 14 Pro. The iPhone 15 treats the 12w charger as if it were a 7.5w charger, but on my iPhone 14 I got 10-12w as you would expect.
no that is not the reason. the usb C power delivery Protocoll doest not understand the 12w anymore.@@GamingWithTravis3 If you meassure the Dataline Voltages. 12W would be 2,7V on D+ and D- But somehow the iphone itself pushed those voltages up to 3.3V So no 12W charging with usb C iphones.
@@jonathonlove9597the shorter the battery stays at 100 % the better. It’s not only the temp. That’s what optimized charging is for. However this works not so optimal. For me it charges phone to 100 % about 2 hours before wake up.
I don't change my mind, I only slow charge my iPhone overnight. I have no need, nor I feel any pressure for fast charging. EDIT: 5W is clearly my favorite! It happens frequently that I leave home in the morning and only charge the phone at the end of the second day. (Exceptions is when I connect it to my car where I can't avoid more charging power) That probably explains why my 14 Pro Max is one year old and it still indicates 98% battery health. I also do this, because I only replace the iPhone every 4 years ... and not because it feels old and slow, it doesn't, I do it because I also want a new toy. To be honest, I suspect this subject of fast charging is a trend out of necessity from many Android users. Even if the battery is weak, any iPhone goes through the day without any problem (with maybe the exception of the SE models).
I commented above that I think I hurt my 14 pro battery by using the 20 watt fast charger for the whole year. My battery got to 87% after one year and I should have used the 5 watt charger. I am not going to do that with my 15 pro max. I upgrade yearly because my plan allows it. (Jump on demand by T-Mobile)
I stopped charging at 5W years ago. I have all 20W chargers in my apartment. My car charger is 18W, and my power bank is 20W as well. I always need to charge my phone quickly when I'm on the go.
Battery heat when charging is not the only thing that reduces the lifespan of your battery. It is actually the 80-100% trickle charge that really hurts your battery health. Using a slower charger will keep you out of that zone longer. The real reason slow charging is becoming less relevant ist the new "Stop charging at 80%" feature, which keep your phone out of the bad levels completely.
I was wondering why my 15 pro max charged to 80 then basically stopped and only charged 1% every 10 minutes. I thought something was wrong. Went into battery settings and turned off that optimization crap. I need the extra battery life throughout the day. If it goes bad I’ll warranty it out with asurion in a couple years.
This is a myth. Keeping your phone between a certain percentage is beyond redundant. The amount of benefits you get I only charging your phone to 80% is beyond minuscule. You’ll see significantly more long-term battery health benefits by not using it in extreme temperatures, not using it when it gets overly warm, and not excessively using it while it is charging.
Apple has also confirmed that these phones will ignore the 80% cap on occasion in order to fully charge for the purposes of battery conditioning. No idea how often that happens, but it has charged past 80% twice with me so far (maybe 4-5 charges between each occasion).
apple 29w charger (used to come with 12 inch macbook and maybe some macbook air) trigger special 14.5v charging protocol, which will actually charge slightly faster than the 9V3A profile from the 30w. on my 15PM with the 29w adapter, i’ve seen around 28W charging speed on my usbc multimeter readings, compared to around 24-25watts from my 30w adapter (agrees with brandon’s results from the video). very unique power adapter, i bought two on ebay just for testing this protocol. i haven’t measured phone temp (i don’t have the fancy thermal cam) but higher voltage means less current to get the same wattage, so it may even keep the phone cooler (or same temp with faster charge?) might be worth looking into. very informative video!
Your comment actually made me order one to try it out! They're quite cheap to come by, and it's always good to have an extra charger lying around! Thanks!
@@ahmadrtube this is most interesting. i was wondering how the stepdown from higher voltage was handled. i’ll have to do my own timed test to see if there is any appreciable difference. thanks for the insight
It may be purely in my head, but quicker charging seems to also discharge faster for me. Would love to know if the discharge rate was the same on these.
Been charging my 13 with 20w between 20-85% since day one, and still got 100% battery health after 2 years. My takeaway is that MagSafe and 0-100 is what kills the battery faster. It’s more convenient though, i get that…
Charge slow, top off the battery and under-charge the capacity. 221 cycles with my iPhone 15 Plus and it's 98% health because I use a 12 watt wireless charger and keep the charge between 75-80% and charge no lower than 25%. By comparison with the same phone for my spouse charging to 100% using a 20 watt charger at 234 cycle and his is at 93% battery health. Doesn't sound like a lot but 5% capacity loss in 7 months isn't good.
Interesting video. However, Im going to stick with my 5w charger for everyday charging aka when I go to bed. The 5W charger could charge my 15 Pro Max in 7 or 8 hours and I would not care a single bit since I am sleeping anyway. Ill keep a higher wattage charger on the side for those moments when I want to fast charge but thats maybe once in every couple of months. Thanks for the video anyway!
I still use my 5w charger, charges it to 100% every morning and I've had my iPhone 14 Pro Max for a year and a bit and battery health is still at 100% and I've charged it SO many times, 100% to 46% every day
former Apple employee here, fun fact, ever since the iPhone 12 you can actually charge at greater than what Apple advertised at 20W. The actual maximum theoretical charging speed spec, per Genius Bar documentation is 27.5W
Whoa. It’s important to remember not everyone charges in ideal circumstances. Ambient temperature and device usage play a huge role in how hot the device gets. You might not care about the 5W in this test, but it will make a world of difference when you try to charge while using the hotspot, gaming, gps, etc. USB-A is still far more durable that C. It’s also plenty(or perhaps more) ubiquitous. It is always a good idea to use a 5W for overnight charging. Use a fast chargers as needed through the day, but people need to stop acting like anyone actually has or should have only one charger. You can easily look up a tear down of that 5W. You’ll quickly see how safe it really is. That design, especially for the time, but even now is very compact and versatile. It will fit in any outlet and is tremendously compact. Again, people should just appreciate the 5W adapter. Modern phones(especially iPhones) have excellent battery life anyway.
Thanks for the video, but you measured temperatures at the end of the charging cycle. Battery health wise, you ought to have measured temperatures at like 50~60%. That’s when it would have been at its highest. I will continue to use the 5W charger overnight so I don’t even need to take my case out to keep temperatures down. Although flawed, still thanks for the video. Cheers from Brazil.
Your test showed clearly that 5w is the only one that wont degrade your battery due to overheating. 20w (41 celsius) and 30w (46 celsius) will damage your battery. Most likely the 12w at 35,5 celcius. Just 0,5 celsius too much. (35 celsius is the upper limit). I strongly disagree with your conclusion.
Yes they designed this specifically so that if you were to use any other charging blocks other than apples 20w block you have to pay extra for, you will get suboptimal results.
@@kalvin126 because I called Apple about it this week and they confirmed that fastest charging is only capable on their OEM 20 watt blocks with the original cord
The batteries charge more quickly from a low state of charge, then taper off as the charge increases to preserve battery longevity. Rerun the experiment, noting the percent of charge after each 5 minute interval to get a better idea of the different charge rates of each of the 4 chargers. On a practical level, for those who need a quick charge from near zero to 50 or 60 percent, it may be advantageous to get the 30 watt charger.
Max temp is not the only consideration. The time spent at any elevated temp has a deleterious effect as well. And with as hot as the 5W charger got, it would be interesting to see how inefficient that charging is. Consider using a device ( P3 P4400 Kill A Watt Electricity Usage Monitor ) between the charger and the outlet to see how many Watts are consumed relative to those that actually make it into the battery.
I know it's not, that's just a simple metric to track and compare in this test. It would be interesting to check the inefficient charging levels of the 5W, good suggestion
Apple’s own protocol is outright trash. Now because the iPhone 15 Pro Max has usb c they locked the charging speed to either 5W or 20W and above. Same with the usb c iPad Air and Pro. The iPhone 14 Pro Max with the 12w adapter took 1h 55min but the 15 pro max took 4hrs wtf. Literally apple forcing everyone to go USB C to C
It’s understandable why they did this. Allowing the iPhones to charge too fast will degrade the batteries quickly. They know they’ll be talked about when it comes to anything. And they don’t want people knocking on their door for new battery replacements
@@MrSamPhoenix I agree but apple locking the charging speed to only 5W when using USB A charger is just outright shit. Because to get anything faster than 5w you have to use a 18w and above pd adapter. It just makes it very inconvenient. The previous few generations of iPhone don't have this problem. Samsung never implemented this too
Thank you very much indeed for this video. I have bought a 15 pro max, although I have no clue when I will receive it. I ordered it from Estonia where the phone still appears to be available for pre-order, with the website for one of Apple's authorised service providers, Ideal, stating that it's "coming soon." But I will definitely bear in mind what this video says regarding charging. I think I was a bit too excited in terms of fast charging, I did not do enough reading when I switched to all USB C chargers at the beginning of the year and ended up spending £40 on a 120W multi USB C plug. It does charge all of my devices nice and quickly, but considering the iPhone only takes up to 30... I think my mac is the only device that fully benefits for now, charging from 30 to 100 in just over an hour and a half which I feel is not too bad for a 2023 macbook pro.
That is true, your Mac can take advantage of much faster charging but not the iPhone. It is still nice to be able to charge multiple devices at once with that 120W block though!
@@BrandonButch It is definitely useful, I can charge up to 3 USB C devices at once and one USB A. One thing I miss out on though, unless I'm just doing it wrong, is standby. You tend to speak quite highly of it in iOS 17 feature videos, but I can't get my phone on its side, it just falls down. I thought you didn't have to have a mag safe stand?
Hi! I live in Estonia, yes, we still don't have iphone for sale in stores here, since yesterday only some iphone 15 and 15 plus 128 GB have arrived for sale, the Pro line is not on sale yet, yes, a person can only pre-order, but when will a person receive this phone, that the seller didn't know or didn't want to tell me. And it's weird why they couldn't tell me when people will get their pre-ordered phones because the pre-order started on September 22nd. And prices are expensive in Estonia.
@@KriTaKriTaKriTa Aren't they? It doesn't help that I am studying there for a year, so all of my accounts and such are based in the UK, so as a result I keep firing up the apple store app to find something that I might need only to remember they will not deliver here... I just hope that they can get the phones on sail soon. I believe they do already have demo models in, so surely it couldn't be that long?
Whoa…. Crazy that the 5W gets that hot. Scary, actually-thanks for that tidbit. I’ve seen an off brand 20W spark too, and ever since I use only Apple 30W or 20W blocks w a cable when I travel, and a MagSafe stand charger when at home to get the full nightstand experience. As always, thanks for all the great Apple info!
Same I always stick with Apple chargers too. It’s just not worth burning your house down obviously so I don’t cheap out on cables and just go with the recommended
I use the Apple 5W charger quite often and have not experienced this kind of heat. The charger is a little warm but no where near what would be classified as hot.
Which charging block do you currently use? 🔋
Lighting, not upgrading this year, but hopefully next year. My ipad pro however I'm using USB-C (Thunderbolt)
@@rexjarvis117 nice! What block are you using?
@@BrandonButch usually for my iPhone 14 Pro Max and iPad Pro is 30W block, I don't use a 5w due to fire hazard
I can't believe the 5W block is very hot; it could've started a fire if kept plugged in. If I used that for my iPad Pro, that power block would blow up and start a fire. It's not worth using a 5W block charger. Newer iPhones, both regular and the pro models, even the iPad and the pro models, need to be higher in watts of power thanks to how powerful the components are.

For 2024, anything above 30 min full charge time is just, absurb. Or maybe because Im so used to 20 min charge time on my Xiaomi 12 Pro 😅

When i refer to "fast charging"... its 10, maximum 15W on a iPhone, 30W on the iPad and 65-140W on my 16" MacBook Pro. Regular charging speeds are for me:
iPhone 12 Mini 5W, iPhone 15 9 - 12W.
iPad Air 5 (M1): 20W (perfect speed, yet a barely warm device!)
16" MacBook Pro: 20W (iPad/iPhone brick), mobile 45W brick or a 65W, 100Wh Powerbank, powerbank mostly just to avoid using the MacBook battery under heavy, sustained load on the go which is like 3-4 hours heavy processing performance just out of the powerbank
I have a 5W and 20W iPad Pro charger at home. My charging blocks don’t seem to heat up that much - so I’m not sure why your 5W brick did. However, my phone stays stone cold on 5W charging while it how generate some heat with 20W or wireless charging. That’s why still plug in my phone with a 5W brick overnight and at the office for topping up. But I use only my MacBook/iPad Pro charger to charge my iPhone when I travel.
You should check your charger more because the 5w definitely heats up a lot
Yee man we in germany got a standard 230V net. Our 5W original Apple Charger was always hot !
5W is ridiculous for anything but a tooth brush
same, im charging my 15 Pro with a 5W brick and id doesn't heat that much, it heats, but normal, and the phone, yes, stone cold.

It would have been better to have a higher wattage charger in the mix since your data shows that none of the chargers are the max advertised speeds. At the very least have a 45w charger to be able to showcase the actual max wattage pulled by the iPhone in a situation where it will have the headroom to do so.
I can do that in another video!
@@BrandonButchplease do!
Agreed
@@BrandonButch If you care to extend the experiments I have a few suggestions: Measure the total energy consumption for the chargers. Running a block for 5:44 at up to 160° sounds pretty wasteful. Also add a MagSafe charger to the list.

Great video bro
Appreciate it bro!
Every new iPhone I have used with the 20W Apple Charger, it makes my battery health go to 90% within 6 months after buying the iPhone brand new. Switched back to the 12W iPad charger, and my 14 Pro Max is at 98% battery health after 8 months.
I've been using an Apple 5W charger for years for overnight charging, but seeing this I think I'll switch it out for a 12W Apple charger that I still have but don't use for anything. Thanks for the info!
I've been a big fan of trickle (5W) charging overnight for my phones, it's not scientific but my 2 and 3 year battery health percentages have never dropped below 97% and 94% respectfully using this method. Same company phones (2 year old 13 Pro Maxs) using MagSafe and 30W chargers are 89% and 88%.
Yes, 5 and 12 watts will run cooler temps on the phone, but the phone will hot during charging for 5 hours, where as using 20 or 30 watt will reduce the charging time which means your phone will be hot less amount time even though the temp will be higher
@@Danik.iceman entonces que es mejor? cargar a 5w durante mas horas y menos calor pero mas tiempo o cargar con el de 20w con el cable trenzado menos tiempo y mas calor? nadie deja nada en conclusion
Interesting to see the difference between phone temp versus block temp. I’d be curious to see a comparison of total power draw from the wall (like with a kill-a-watt) for each charger type.
It’s called kilowatt, not “kill-a-watt”. Besides, what did Watt do to you to deserve to be killed? /s
kill-a-watt lmao
Kill a watt is a brand of outlet power rate measuring device
@@orlandosaenz1553 oh, in that case I'm sorry. I though you were thinking that kW is kill-a-watt instead of kilowatt.
why do less potent chargers heat more than the most potent ones?
I have a 20W charger, I wish there was a way to set the charger on lower wattage... sounds stupid I know.
I have had androids before with fast charging capabilities and honestly I never used them, because I had no need for it.
Even with 20watts, that iPhone 15 I have charges up pretty quickly.
I have been using an Anker Nano II 30W for my 14 Pro for one year now. I never use magsafe and never charge it overnight but only at breakfast or in the evening. I start charging at 30-35% till it's at 80-90%, sometimes 100%, and still got 100% battery health. My charging behaviour was the same with my P30 Pro (45W charger) and I couldn't notice any significant difference in battery life after 3,5 years. I don't play games on my phone though, might be a factor for faster degrading batteries, don't know.
Playing games makes your phone slightly hotter and drains your battery faster, thus makes you charge your phone more than once a day and will consume the battery health.
Intersestingly my 15 Pro Max takes max. 27 watts from a 45 watts charger and achieved 0-50% in 25 min
0-60% in 30 min
Interesting Video. Thank you for this. Do you have any plans to redo the test using the charging optimization? I'm curious to see if the slight difference between the 20w and 30w is negated from the apple optimization.
turning off the charging optimization wont do anything if the iphone is new and also if you take care of the battery( taking your phone off the charger immediately after it gets to 100 percent everytime).
Could it be you had defective 5w charger? I have used 5w with iPhone 11 Pro Max for several years and it really helped to prolong battery health. Or is really 15 pro max taking so much more power?
It’s always funny when testers make those long faces about long time charging cause I don’t really care because I always charge at night and I usually sleep at least 7-8 hours. How it is so hard to understand? I only need fast charge during day but that hardly happens. The longer the battery health lasts the better. Anything else is not important.
Whats better for iphone 15 pro max? 20 w or 30 w? I can’t really decide
Get 20w, less heat, charges fast enough... Just charge it when you go to bed and you will wake it with it fully charged, or even get a 10w charger tbh if you wanna do that
That mean is ,if you rental your iphone need return after 2 years, use 30W. If you bought your iPhone 12W is better for protect your battery life
For the health of the battery is better to have a slightly minor charging temperature but for more time (12w) or higher temperature but for half of the time (20w)?
muy muy buena pregunta. a ver si alguien es capaz de decir algo
this is one of the best video about apple charger because it shows temperature of phone and this is important for battery health,tnx
It would be interesting if you found a way to keep the phones cool during the fast charging to see if it would make the 30W pull ahead. I wonder if the increased temperature caused Apple to throttle how many watts it was pulling.
Its also about how battery work , it slows down not only because of temperature. So you can't know for sure anyway
Wow ok, so anything above 30C / 86F is too hot according to some researchers, to avoid battery degradation. So to me, I want to ensure I'm using the lowest charging wattage possible, at all times, and the phone has a way to cool off, I'm hoping for the 16 series this is improved with the new battery casing
20W charging plug either with direct cable or Apple MagSafe both of which superheated my 15 Pro. So for overnight I switched back to Apple 5w charging plug and it is naturally cooler.
Question on the 5 watt charger
Is it 5 volt @ 1 amp ? Or 2 amp
Having the temperature + the power meter is what makes your video stands out.
I loved how he has shown all the graphs of temperature, wattage & more. I try to use 5W to keep my phone cool at night but this video showed me how hot the block gets. I’m going to move to the 12W now. Thanks!

Very interesting test ! 👌 I use also 20 W for my iPhone 13 Pro Max and I was looking for the best option for my new iphone 15 Pro Max. I think I will continue charging with the 20W Apple block charger.
Does the 5W charger has been discontinued? I can´t find it anywhere.
just what i felt through my hands the results are as i expected. The best slow charger is the 12w ipad charger for new iphones. I love these. Literally in summer still keeps my phone cool, but the 20w is the one that gets it too hot in summer.
Es más recomendable usar 12w entonces afecta menos la degradacion de bateria no?
I would like to see a test where the phone is being used while charging. I’ve seen the phone pull as much as 27 W when being used. That’s where using the 30 W charger makes the most difference.
Good video Brandon. But I don’t believe a 5 watt charger will ever put you at risk of fire as long as it isn’t damaged and the wall outlet or surge protector isn’t damaged. 160 degrees is hot but not hot enough to set fire to a carpet/wood floor/ blankets/paper etc. Those 5 watt chargers have been around for over decade and a half. Never heard of widespread fires. Just my 2 cents
It was sarcasm lol
@@BrandonButchthat was definitely not sarcasm in the video 😂
@@NickNow guess I should get a career in acting then because I fooled you 🤣
Hard to tell whether the charger or phone is slow. Thanks, every bit of information helps.
Great comparison and analysis… clear and really like it. Just to share my experience: i did mine for iphone 15 promax, from 0% - 100% (using 20w) only took 101 minutes.
Very interesting test. It would be also interesting to check how much energy is actually used overall as it is liikely that the 5W charger is using as many Wh as the 12W, just that a lot of it is wasted in the 5W charger, which would explain the heat.
I guess you can use the 12W during night and 30W during daytime cuz of in daytime you need your phone while it can take time during nights
that seems like the optimal setup

Try sticking a black, matte electric tape to the screen or back of the phone. These kind of thermal cameras will pick up heat from the reflections, @4:40 you can clearly see the heatspots are the reflections from your hands and the phone which captures the image.Ű
Sticking a non reflective tape will prevent this anomaly.

“Trickle charging” has been implemented on most Apple devices at 80% to protect the battery
I used to work in a company that designed a charger control chip that basically speaks to the battery charge control unit in the phone and let me tell you that it much more complicated than just plugging it in and pumping current into the massive capacitor (battery).
Interesting to see the 5W supply heating the socket to 160F - Wonder what current the charger itself was taking in from the mains. Perhaps you could have had them plugged into smart sockets to illustrate how much power the charger was actually consuming to deliver the output to the battery.
Power supplies normally have a TDP matching highest rated power delivery but run more efficiently when not maxed out. A 45 watt PD brick would run much cooler than a 30 watt one if both were supplying 27 watts to the iPhone. When the 5 watt brick first came out devices probably didn’t pull 5 watts the entire charge time but a current phone probably pulls that the whole time since battery technology has evolved to stay cooler.
Perhaps his 5W charger was already aged/damaged too heavy. So if, he could show at best that you better replace your chargers here and then when the components aged too much and they get inefficient and hot.
My 5W iPhone charging brick from like iPhone 5/6 times barely gets warm, as it has to be, considering they have about 80-90% efficiency (so MAXIMUM 1W heat output)
Its also sad, but i dont have any use for the 5W brick anymore since i changed from iPhone 12 Mini (8Wh) to 15 (13Wh), the longer charging time on the iPhone 15 is horrendous with 5W (about 2 vs 4 Hours for 0-100%).
But newer iPhones i exclusively (if possible) i charge with something slower than 15W. A Samsung fast charging brick charges my iPhone 15 with about 5V and 2.1A for 10W, 10W is at least for the iPhone 15 (no Plus or Pro Max) a sweet spot of usable "fast" charging speed AND barely noticeable warming up.
I've used 5W charger for 13PM, 14PM before and now using it for 15PM too. I got the 20W charger too, which I use only when I'm in a hurry. The point is, I don't see my 5W charger getting that hot like you've shown here, never. And I can confirm from my experience, using a 5W other than the 20W makes a difference for the battery health in the long run, pretty big one actually.
After having a iPhone 8+ with 87% battery health after 5.5 years, I only use the 5W charger now for my 14. The battery level remains higher through the day compared to when I was using the 20W charger.

Hmm what’s going on with the phone on the right at 3:24? Looks like a bug with the status icons.
temperatures higher than 35 degrees are bad for battery (apple info). So it's a good idea to use 12w brick at least during overnight charging which provide better battery health along with 80% limit option turned on. Good thing if you don't wanna 88% of battery health after one year usage as in 14 iphone lineup. On a mac I use AlDente app and it stops charging as temp hits 35. I'm stiil at 100% battery health after one year

maybe over 3 hours 🤣🤣🤣
2:48 that's not throttling. That's the charging voltage threshold at 80% dropping from 9v to 5v.
How I want to shout at the top of my lungs to make iphones charge faster. It's a myth anyway that fast-charging ruins your battery.
2:52 when he swipes up the animation lags
its been like that for a year and apple still didnt fix that
I use 5W charger, typically top up 30ish-80% every morning at my desk while I work. I have used 12W USB-A charger when I'm in a bigger hurry and when plugged into my trick. I have only used 20W USB-C charging a handful of times when time was of the essence. Currently at 98% battery health on a 14PM bought two weeks after launch. I want Apple to bring the 80% charge limit feature to at least the iPhone 14!
98% after a year, quite good
4:50 No thats wrong, it can not start a fire. I use it every night for the past 2 years and I don´t have any heating issues.
I also noticed that I got slower charging with the 12w charger with my iPhone 15 Pro compared to my old iPhone 14 Pro. The iPhone 15 treats the 12w charger as if it were a 7.5w charger, but on my iPhone 14 I got 10-12w as you would expect.

It is crazy how few people have basic electrical education, let alone know how and why a battery works how it does
I don't change my mind, I only slow charge my iPhone overnight. I have no need, nor I feel any pressure for fast charging. EDIT: 5W is clearly my favorite!
It happens frequently that I leave home in the morning and only charge the phone at the end of the second day.
(Exceptions is when I connect it to my car where I can't avoid more charging power)
That probably explains why my 14 Pro Max is one year old and it still indicates 98% battery health.
I also do this, because I only replace the iPhone every 4 years ... and not because it feels old and slow, it doesn't, I do it because I also want a new toy.
To be honest, I suspect this subject of fast charging is a trend out of necessity from many Android users.
Even if the battery is weak, any iPhone goes through the day without any problem (with maybe the exception of the SE models).
I've had iPhone 12 and after 11 months the battery dropped to 99%
I commented above that I think I hurt my 14 pro battery by using the 20 watt fast charger for the whole year. My battery got to 87% after one year and I should have used the 5 watt charger. I am not going to do that with my 15 pro max. I upgrade yearly because my plan allows it. (Jump on demand by T-Mobile)
I stopped charging at 5W years ago. I have all 20W chargers in my apartment. My car charger is 18W, and my power bank is 20W as well. I always need to charge my phone quickly when I'm on the go.
Battery heat when charging is not the only thing that reduces the lifespan of your battery. It is actually the 80-100% trickle charge that really hurts your battery health. Using a slower charger will keep you out of that zone longer. The real reason slow charging is becoming less relevant ist the new "Stop charging at 80%" feature, which keep your phone out of the bad levels completely.
I was wondering why my 15 pro max charged to 80 then basically stopped and only charged 1% every 10 minutes. I thought something was wrong. Went into battery settings and turned off that optimization crap. I need the extra battery life throughout the day. If it goes bad I’ll warranty it out with asurion in a couple years.
Have it on, on the weekends in workdays I change i back
This is a myth. Keeping your phone between a certain percentage is beyond redundant. The amount of benefits you get I only charging your phone to 80% is beyond minuscule. You’ll see significantly more long-term battery health benefits by not using it in extreme temperatures, not using it when it gets overly warm, and not excessively using it while it is charging.
@@GlubySnotGlubbiest it's not a myth, Engineers are the one who implement these features. They've A/B tested all these features and it works.
If you charge over night it’s totally ok to have this function, you’ll have it full when you wake up. I can mostly go 2 days with one charge.
Apple has also confirmed that these phones will ignore the 80% cap on occasion in order to fully charge for the purposes of battery conditioning. No idea how often that happens, but it has charged past 80% twice with me so far (maybe 4-5 charges between each occasion).
same mine did that too
can you do this test with apple watches and different blocks?
apple 29w charger (used to come with 12 inch macbook and maybe some macbook air) trigger special 14.5v charging protocol, which will actually charge slightly faster than the 9V3A profile from the 30w. on my 15PM with the 29w adapter, i’ve seen around 28W charging speed on my usbc multimeter readings, compared to around 24-25watts from my 30w adapter (agrees with brandon’s results from the video). very unique power adapter, i bought two on ebay just for testing this protocol. i haven’t measured phone temp (i don’t have the fancy thermal cam) but higher voltage means less current to get the same wattage, so it may even keep the phone cooler (or same temp with faster charge?) might be worth looking into. very informative video!
Your comment actually made me order one to try it out! They're quite cheap to come by, and it's always good to have an extra charger lying around! Thanks!

Been charging my 13 with 20w between 20-85% since day one, and still got 100% battery health after 2 years.
My takeaway is that MagSafe and 0-100 is what kills the battery faster. It’s more convenient though, i get that…
No way that’s true, 100% after 2 years!!!
Charge slow, top off the battery and under-charge the capacity. 221 cycles with my iPhone 15 Plus and it's 98% health because I use a 12 watt wireless charger and keep the charge between 75-80% and charge no lower than 25%. By comparison with the same phone for my spouse charging to 100% using a 20 watt charger at 234 cycle and his is at 93% battery health. Doesn't sound like a lot but 5% capacity loss in 7 months isn't good.
Interesting video. However, Im going to stick with my 5w charger for everyday charging aka when I go to bed. The 5W charger could charge my 15 Pro Max in 7 or 8 hours and I would not care a single bit since I am sleeping anyway.

former Apple employee here, fun fact, ever since the iPhone 12 you can actually charge at greater than what Apple advertised at 20W. The actual maximum theoretical charging speed spec, per Genius Bar documentation is 27.5W
One of the best videos on YT. Great job.
Slightly off topic but what Note app is that you’re using?
Whoa. It’s important to remember not everyone charges in ideal circumstances. Ambient temperature and device usage play a huge role in how hot the device gets. You might not care about the 5W in this test, but it will make a world of difference when you try to charge while using the hotspot, gaming, gps, etc.
USB-A is still far more durable that C. It’s also plenty(or perhaps more) ubiquitous.
It is always a good idea to use a 5W for overnight charging. Use a fast chargers as needed through the day, but people need to stop acting like anyone actually has or should have only one charger. You can easily look up a tear down of that 5W. You’ll quickly see how safe it really is. That design, especially for the time, but even now is very compact and versatile. It will fit in any outlet and is tremendously compact. Again, people should just appreciate the 5W adapter. Modern phones(especially iPhones) have excellent battery life anyway.
Could you tell hat’s the wallpapers please?
Thanks for the video, but you measured temperatures at the end of the charging cycle. Battery health wise, you ought to have measured temperatures at like 50~60%. That’s when it would have been at its highest. I will continue to use the 5W charger overnight so I don’t even need to take my case out to keep temperatures down. Although flawed, still thanks for the video. Cheers from Brazil.
Your test showed clearly that 5w is the only one that wont degrade your battery due to overheating. 20w (41 celsius) and 30w (46 celsius) will damage your battery. Most likely the 12w at 35,5 celcius. Just 0,5 celsius too much. (35 celsius is the upper limit). I strongly disagree with your conclusion.
More than 2 hours of charging is crazy

@@EBMJ any other 20w+ Power Delivery charger can charge the phones just the same. Ankers for example.
@@kalvin126 Apple has compatibility readers fyi. But to the case of specific 20w I don’t know anything about other brands so…
Cool watch band, where'd you get it?
The batteries charge more quickly from a low state of charge, then taper off as the charge increases to preserve battery longevity. Rerun the experiment, noting the percent of charge after each 5 minute interval to get a better idea of the different charge rates of each of the 4 chargers. On a practical level, for those who need a quick charge from near zero to 50 or 60 percent, it may be advantageous to get the 30 watt charger.
does apple still sell the 12W brick ?
Max temp is not the only consideration. The time spent at any elevated temp has a deleterious effect as well.
And with as hot as the 5W charger got, it would be interesting to see how inefficient that charging is. Consider using a device ( P3 P4400 Kill A Watt Electricity Usage Monitor ) between the charger and the outlet to see how many Watts are consumed relative to those that actually make it into the battery.
I know it's not, that's just a simple metric to track and compare in this test. It would be interesting to check the inefficient charging levels of the 5W, good suggestion
is there a link to the wallpapers on the phones in the video? :D
Apple’s own protocol is outright trash. Now because the iPhone 15 Pro Max has usb c they locked the charging speed to either 5W or 20W and above. Same with the usb c iPad Air and Pro. The iPhone 14 Pro Max with the 12w adapter took 1h 55min but the 15 pro max took 4hrs wtf. Literally apple forcing everyone to go USB C to C
It’s understandable why they did this. Allowing the iPhones to charge too fast will degrade the batteries quickly.
They know they’ll be talked about when it comes to anything. And they don’t want people knocking on their door for new battery replacements
@@MrSamPhoenix I agree but apple locking the charging speed to only 5W when using USB A charger is just outright shit. Because to get anything faster than 5w you have to use a 18w and above pd adapter. It just makes it very inconvenient. The previous few generations of iPhone don't have this problem. Samsung never implemented this too
Which cable did you use for the 5W brick?
Thank you very much indeed for this video. I have bought a 15 pro max, although I have no clue when I will receive it. I ordered it from Estonia where the phone still appears to be available for pre-order, with the website for one of Apple's authorised service providers, Ideal, stating that it's "coming soon." But I will definitely bear in mind what this video says regarding charging. I think I was a bit too excited in terms of fast charging, I did not do enough reading when I switched to all USB C chargers at the beginning of the year and ended up spending £40 on a 120W multi USB C plug. It does charge all of my devices nice and quickly, but considering the iPhone only takes up to 30... I think my mac is the only device that fully benefits for now, charging from 30 to 100 in just over an hour and a half which I feel is not too bad for a 2023 macbook pro.
That is true, your Mac can take advantage of much faster charging but not the iPhone. It is still nice to be able to charge multiple devices at once with that 120W block though!
@@BrandonButch It is definitely useful, I can charge up to 3 USB C devices at once and one USB A. One thing I miss out on though, unless I'm just doing it wrong, is standby. You tend to speak quite highly of it in iOS 17 feature videos, but I can't get my phone on its side, it just falls down. I thought you didn't have to have a mag safe stand?
Hi! I live in Estonia, yes, we still don't have iphone for sale in stores here, since yesterday only some iphone 15 and 15 plus 128 GB have arrived for sale, the Pro line is not on sale yet, yes, a person can only pre-order, but when will a person receive this phone, that the seller didn't know or didn't want to tell me. And it's weird why they couldn't tell me when people will get their pre-ordered phones because the pre-order started on September 22nd. And prices are expensive in Estonia.
@@KriTaKriTaKriTa Aren't they? It doesn't help that I am studying there for a year, so all of my accounts and such are based in the UK, so as a result I keep firing up the apple store app to find something that I might need only to remember they will not deliver here... I just hope that they can get the phones on sail soon. I believe they do already have demo models in, so surely it couldn't be that long?
Watch my unboxing of the iPhone 15 Pro Max! 📦🫶
Is there flir working for iPhone 15?
Whoa…. Crazy that the 5W gets that hot. Scary, actually-thanks for that tidbit. I’ve seen an off brand 20W spark too, and ever since I use only Apple 30W or 20W blocks w a cable when I travel, and a MagSafe stand charger when at home to get the full nightstand experience. As always, thanks for all the great Apple info!
Same I always stick with Apple chargers too. It’s just not worth burning your house down obviously so I don’t cheap out on cables and just go with the recommended
I use the Apple 5W charger quite often and have not experienced this kind of heat. The charger is a little warm but no where near what would be classified as hot.
