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.
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.
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.
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 :) )
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.

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 😊
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!
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.
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
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
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.
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 :(
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!
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
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
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.
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?
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
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.
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
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
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.

Check your startup apps. You might have battery-suckers loaded by default.

Try formula "(current maximum capacity in mAh x 100) / original maximum capacity in mAh".

Coconut battery shows it also, as well as battery charge status. Pretty cool.
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 😂
THEY DONT FOLLOW A LINEAR RELATION THEY MAY GO UP AND DOWN SO 94% IS THE CLOSEST TO YOUR REAL BATTERY HEALTH
