- Calculation: (Your Battery Cycle Count x 20) / 500 = How much capacity you lost
Do you know the Maximum Capacity on your iPhone Battery Health is generally incorrect?? In this video I show you how to check the real number, the real percentage, with the Battery Cycle Count! Hope U Enjoy!
Technical Information (Apple Support):support.apple....
This is a way over-simplified "calculation" of battery health. Cycle count is not the only determining factor. You could buy a brand now MacBook (Air, Pro), leave it plugged in all the time, have a very low cycle count and the actual battery health will still be less than 100%.
thats what I have been facing with my m1 air. I had always used it in clamshell mode and due to that the battery health is at 87% with only over 101 cycle count. I am doing a battery recalibration to see whether I notice any different results.
@@pranshusingh2000 sooo what are the results after recalibration
@@pranshusingh2000 have the same, did it helped?
if you can clear my doubt, it would be greatfull . my mac book m1 air was purchased 274 days ago . now its showing 76 cycles and 94 %. i feel the charge is draining much faster compared to the beginning stages. i had contacted the support team and had done an offline diagonisation and showed that this mac is perfectly alright but i am confused , i still feel the battery is draining fast.
Check your startup apps. You might have battery-suckers loaded by default.
The most important factor is the ratio between the original maximum capacity in mAh and the current maximum capacity in mAh.
Try formula "(current maximum capacity in mAh x 100) / original maximum capacity in mAh".
There are enough apps to read this data.
Which apps what’s the name
This information is incorrect. There are other factors besides charge cycles to determining battery health (age, heat, depth of charge/discharge). Plenty of battery apps that will give you current max capacity mAh, which would be most accurate way to calculate battery health (current max capacity/original max capacity)x100.
My 2020 M1 macbook pro battery reads 94% battery health but I've lost 11% of my max battery capacity.
which apps do you recommend to check?
It's not linear calculation, may be 94% is correct. I have one 224 cycles and battery below 78% and replacement required.
When it's get older cycles count 1000 for 80% never achievable.
This is an April Fool's joke, right? 🤣
The number you get from this calculation is fake. There are many things that can change battery health. Not all devices ship at 100% battery health, some have more than 100%, some have less. Temperature, charging habits, and improper storage also have a say in degrading the battery.
It is not correct to try and calculate maximum capacity by trying to calculate it from the battery cycles, but rather to check the current maximum capacity it can hold in mAh, and then compare it to the original advertised maximum capacity in mAh. While cycles do have some say in the battery health, it is far from the only determining factor here
Hey can you explain more about the formula you used to calculate REAL battery on macbook? Why multiply by 20,...
Nevermind I figured it out. 1000 cycles leave the battery remains 80% so => it’s 20% of the real capacity
Yep, is just a linearization for a phenomena that is not linear 😂
This is half true, but half wrong i think.. because in my case, my battery cycle counts were only about 350 out of 1000 (macbook pro 16); however, the apple genius told me that my battery health level is below 80% so that i could repair my battery to new one for free with apple care. He said battery cycle is one of the important factors of battery health, but the charging and using style is also a big factor for battery health. ( for instance, even if we have 500 cycles, making your laptop to all the way down to 0 percent and recharging it for 500 times, and keeping your laptop over 20 percents every time without having a battery drained is a huge big difference. (English is my second language. Sorry for the poor grammers :) )
My 2015 13" Retina MacBook Pro has 473 cycles and the calculator says it should have 90% battery health. However, the coconutBattery application shows 85%... And your MacBook could have only 100 cycles but a health of 80% when it was only used plugged in to the charger the whole time or 500 cycles with 92% for example when the battery was used frequently but it didn't drain to zero for an extended amount of time or was left at 100% for days.
This video is a bit oversimplified as charging cycles are just one factor in a whole host of metrics that affect battery performance over time. The percentage displayed is a comparison between the available capacity of the battery and the design capacity. Charging habits play a part in overall battery health also. If your battery spends a significant amount of time fully charged or nearly dead you can degrade the battery more than is typical without registering additional cycles. Storing a battery fully charged or depleted for an extended period of time also negatively impacts battery health and will not register cycles. The battery management software built into MacOS is great but good user practices will take you much further than software alone.
THEY DONT FOLLOW A LINEAR RELATION THEY MAY GO UP AND DOWN SO 94% IS THE CLOSEST TO YOUR REAL BATTERY HEALTH
Hey Daniel, is there any way to trick the battery cycle count ? I mean is it possible to change it by any bypass or hack method ?
I bought M1 Macbook Air 2020 and it has only 7 cycle count. As I checked it has been bought in 2021. The thing is battery is Never replaced.
So I wonder if there any bypass to change the cycle count. What do you think about it ?
Is it possible ? just 7 cycle counts for almost 2 years ?
Waiting for your reply 😊
It can happen if the macbook are always charged when used. Macbook bypass battery if its plugged in while fully charged.
@@bluocn Hii can you give me an advice? Mine has 96% and 39 cycle count. How can i prevent from dropping?
@@jiennash2134 keep ur macbook plugged in while used. that way it will use power from the outlet instead of from the battery.
@@jiennash2134 my mac too has 30 cycle count with 96% smh
The description on the site you're on shows a faster way to get to the System Information window . Select the apple icon in top-left, then hold down the 'option' button. That turns the top link to 'System Information'.
battery capacity can be affected by several factors, temperature is a big one.
as an embedded systems engineer, I can assure you that that formula is not even close to accurate.
the only way to measure the maximum capacity of a batter is by charging it to 100% and then discharging it to 0% and measuring the total energy outputted, which is what your Mac is doing
My cycle count is 892. Is it due for a change? The fully charged battery runs down overnight to 1% when it's on sleep mode.
Battery cycle and health is a not a linear graph. Battery health falls faster for the initial 5-10% and slowly later on
Thank you for the video. I think that cycle count is not the only factor that affects the battery health/capacity. Indeed, it is one of the major factors, but there are other aspects such as temperature, whether you kept updating the OS and using an original charger or not, among others. The 80% capacity mentioned on the Apple website is actually considering ideal conditions/usage; hence it may not be applicable to each and every case. If you use your MacBook within it's comfort zone, then your maths are right, otherwise you might find close numbers like just what you found. Best regards!
hope you see this and you answer i need help what kind of adapter should I use for my iPhone XR in terms of watts?
Hey bro can you help me? I bought a MacBook air m1 just 1 month ago now my Macbook showing the wrong battery percentage like last time when I switched it off at 82% and after restarting, it showed me 84 % this happened to me so many times. Are you facing this issue too? During use it drains normally but after restart it jumps 1 to 2 percent up
Did you get any way to fix it
Same thing brother😢, even I have noticed it in mine
Hi!! I have the MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports). My battery health when calculated came down to be 91.06% but under the Health Condition section, condition says service recommended but I dont understand why?
Please help :(
mine is brought around same time， and I checked，it 2700+ circles and I changed battery once already。。
My MacBook is 2017 max, it is having issues with charging and count number is 147. Not that high?
Very helpful! Thank you. 🤗
My cycle count is 50 after 9 months. Good?
Hi, if a Macbook gets refurbished, that is, formatted and a new OS installed, will the battery cycle count be set to zero or will it still show the actual cycle count? Thank you!
it will show actual count only
Long story my short, you are wrong. You assume that cycle count is the only thing that is affecting battery health, and yet, that assumption is not correct at all
Pretty funny. This is like an April Fool's video.
Thank you for the invaluable info.
It DOESN'T work like that... Things other than cycle count also affect battery capacity.
Exactly. This is kind of comical.
This is kind of like thinking you'll actually get the gas milage listed on the sticker of a new car.
Thanks :)
Should i change my battery on my 2012 macbook pro? it has 1527 cycles on it already
"already" ? It's been 11 years since 2012. Which software update are you running your 2k12 Mac on?
no, it is OK
Nice video! right now I have the “Service recommended“ message. It’s working okay but when I check my cycle count it’s about 1431 knowing the maximum cycle that falls under my 2019 MacBook Pro is 1000. What happens if you keep the cycle count building up more?
Woah! How long's the battery lasting?
@@ahmadnouman3784 it last me around 1hr n 10 mins with no brakes. Did you exceed the max cycle counts and do you have the same message ?
the battery just degrades further. Maximum cycle count is just the number of cycles it is designed to withstand while being at least over 80% health. If you continue the battery health will just go under 80% health and then go lower and lower. This is not dangerous but it will just get worse and worse at holding a charge. If battery life is important to you you can change the battery, but if you do not need long battery life it does not matter to have poor battery health
@@oh-noe Hi there is MacBook Pro 13 inch 2017 with around 86.92 as per this calculation is ok ?around 5 hrs run time currently? how long will the battery likely to lost before dying out?
@@flyhigh5066 I’d say it would last many many years more before dying out.
Unless something unexpected happens and the battery starts bloating or suddenly stops functioning, you can continue to use it for years to come.
Battery life will of course go lower and lower during this time but if it doesn’t bother you to have a few hours less than you are supposed to, you can just keep that battery until you change out the laptop for a newer one in the future
idk how to keep the battery healthy there's so much wrong info
There is one big thing that even companies use. Try and make sure that your battery is not at 100% all the time, and try and make sure it does not go to 0% a lot.
When you buy a new device it often has 40%-60% already charged out of the box. This is because at around these levels the battery degrades much slower so they can be stored before purchased. Smart batteries for example in some drones do this as well. If you charge a dji battery to 100% and leave it for a couple of days, it will lose about 40% charge on its own to try and minimise damage over time.
It is fine to charge it fully and use it, just don't let it stay 100% for weeks without use, and definitely try and avoid reaching 0% often.
my macbook air m1 has 300 cycle and says 83% already, with formula its at 93% but i think this formula is just hypothetical, i use my mac for nearly 5 hours a day for 2 years so i think that, although system shows whatever battery health, it is more correct than the hypothtical one of yours.
My cycle count is 48 and Battery capacity is 93%
Hey Daniel, do you check your emails? I sent one a couple days ago to your business one. If you have a sec, you mind checking?
Hi! My Macbook Air 2020 with Cycle Count 87 but the maximum capacity reach 96%, is it normal?
yes every MacBook has a slightly different battery health. If it goes under 80% before 1000 cycles that is not normal, but as long as it is over 80% it is fine
@@oh-noe At what percentage is it best to charge? previously I charged it at before 20% but now I do it every 50%.
@@bembenkwibisono9278 as long as it doesn’t go under 20% it is fine. A good rule of thumb is to try and keep the battery between 20% and 80%.
is 676 cycles after 4 and a half years good?
that does not sound like you use your Mac a lot. Yes that is pretty good.
I just got my gf a used MacBook Pro mid 2012 and they said it’s a new battery it says the battery cycle count is 4, condition normal, full charge 6160 (mAh) is that good
No, you need to replace the battery

thank you✅👍

i bough macbook pro m1 pro 14 inches my capacity is 86% and my cycle is 98 is it legit ?
thanks Daniel, my cycle count on my air m1 mac only 27 and my capacity 99%. then i checked the way u did, its true. my mac capacity is 99% with calculation 99.946. im a little bit worried about that
Mine is at 96% and only has 28 cycle count. So what you see in the computer is not really accurate? 🥲
yea dude i dont think so

You can't I think. Mine has now dropped tto 95 at 31 cycle count. It's crazy. I stopped caring about it. Lol@@jiennash2134
@@jiennash2134 mine got to 93 at 48 cycles 😥
I got a mac m1 like 1 and a half year ago and didn't understand anything. The battery capacity is 87% and cycle count is 332. im really worried cuz this all happened in just a short period of time, anyone got tips?
where did you get that formula from ?
the only thing left from your daddy ?
I'm confused.
My M1 mac is near 2 years old, but I've used it very little.
About 80% of time, it has been plugged via usb-c to the monitor or sleeping.
According to system info, it has completed 41 cycles and its battery health says is 97%.
If I do your formula, the result is a whooping 99,18% of battery health.
And in the other hand, I've just installed "Stats" app and it provides a battery health checker and it gives me a 90%.
- So, which one should I trust?
- Is it bad to have it connected via USB-C to the monitor instead of using the official charger and a HDMI?
Can you or anyone reading, throw some light?
Thanks.
My battery health increased from 90 t0 94.5 (i use coconut battery to check the health)
can someone help me? I have a 2019 MacBook Pro 16 inch, and when I go to battery on settings, it doesn't show my battery health's percentage. does anyone know why?
i have the same.. :(
MacBook Air 2021, cycle count 750? It's OK?
same mine is 808
Oh shit mine is like 85.58% it’s been like 3 years since I have bought my MacBook Air I’m not sure if it’s good
Everithung like you... but the exception is you 94% an I have 86%...... mine is from January of 2021...!
my cycles for MacBook Pro 2018 are 193...
Can someone tell me what my actual health is.
it showed 61 😳
that's crazy low right!!!
can we do this for iphone?
this method is flawed, it is not the real battery health because there is a lot of other things that affect battery health like temperature or charging habits. Charge cycle is not the only thing affecting battery health
my cycle count is 1960, lol. "Service Recommended" oops!
well my cycle count is 71 and my battery HEALTH is 70%!!!!!!
my cycle count is 1439 💀. i just bought my mac 2 years ago 😭
😹😹😹💔
Install Cocnut Battery
interesting
My cycle count is at 591
688 & 88%
i have m2, 134count but on 89% bh...wft apple? haha
i hv m1 air ,mine is in 95% after 27count
how mach number of cycle when by a new mackbook 2023?
great video. This makes sense.
