MacBook Air m1 battery reduced to 98%

My Air M1 has 39 loading cycles and and battery health at 91% after 9 month usage.

send it in on monday, repair is finished but i dont know what they have done.

ill get it back soon.

hope they changed the battery

I am really worried. Mine is 3 weeks old, 8 cycles and battery health at 95,1 %. This is outrageous if you ask me. It drops almost one percent every time i charge it. I never leave it plugged in and never go beyond 30%

Got mine in early April. Only at 19 cycles, but down to 94%. That's pretty crazy. I use it for work and need to have it powered up so it can run my monitor. I'd go nuts if I had to work on a 13 inch screen all the time. I know I should take it off power more often and just work for a day or 2 until it runs down all the way, so maybe I'll suck it up an do that every couple of weeks. But losing 6% in just a few months is crazy, especially when they tout it for it's amazing battery life...

I have just watched a video on re calibration for battery they say take the battery down to zero then leave for a couple of hrs then re charge to 100% without using and it should set it to zero and full don’t know if anyone has seen this before

same problem faced by me also

and now my battery percentage further reduced to 95 and now only 3 months are left for my warranty end and when i contacted apple support they told me that its ok till it reduces to 80% (claim that after it reached 80% it would take 1000 charging cycle to reduce further )

i wasn’t happy with answer but has no option !!

But if it drops below 80% at under 1000 charges even it it’s 18 months old there shouldn’t be a problem getting it changed should be ok under uk law especially with the guarantee that at 1000 it should be not lower than 80%

Sometimes we can only trust big companies doing the right thing like Google cloud charges me $0.01 without me knowing until Bank notified me and i contacted them, then there support says related person used the card is contacted but i received no message/email lol.

it costs around $300 (20% of M1 air price lol) to replace the battery for my i5 this year, not sure about M1 but Try to avoid using battery when you heavy applications or using lots of Cpu

Give them a bit of time to optimise stuff and trust to optimise stuff soon :))

I am at 94% battery health with only 56 charge cycles. Contacted Apple customer support 2 times already and they both told me the same thing "The battery seems to be working just fine ". That is absurd !! Can someone help me..?

For the record, mine is still at 100% after 34 cycles. I would like to point out that although it's normal for battery health to deplete over time, the key variable of interest here is the rate at which it depletes relative to the number of cycles. If I understand correctly, these batteries are supposed to take ~1000 cycles to deplete to 80% health. That works out to a 1% drop per ~50 cycles. So you should expect your first drop to 99% after ~50 cycles; 98% after ~100 cycles; 96% after ~200 cycles; 90% after ~500 cycles; etc. So if anyone's battery health is dropping at a significantly higher rate than that, it is not normal and should probably be serviced or at least checked out.

Guys, I came here because mine is at 95.2% and only has 20 charge cycles. I purchased my M1 MBA in June, so it's only 4 months old and the manufacture date is May 2021. I sold my older Certified Refurbished Mid 2014 MacBook Pro Retina (bought in 2015) with more than 90% after 6 years of use and 280-ish charging cycles. I can't believe this is normal behavior.

it's hard for them to test whether popular applications like VSCode or Chrome works well with the new cpu architecture which may cause lots of cpu consumption and kill the battery pretty quickly.

It used less than 2G of memory for Chrome when i removed all enabled but unused plugins like Google Docs ... or Video related plugins!

If you buy a $2k machine just to read news & email, it should not be a problem :))

FYI: with similar # of Chrome tabs for my 2015 intel cpu, the memory is not as high so i think they'll need time to optimise apps for the new architecture to work efficiently when you open multiple of them.

I have the same problem. I bought my MacBook Air M1 less than 6 months ago. Didn't use it on battery much because I almost always needed to use external SSD. And when I use external devices the battery drains 2-3 times faster. So I used it mostly plugged-in. Also, 99% of the time I used M1 optimised apps (Safari and the latest version of DaVinci Resolve).

Now, I have only 18 charging cycles and it shows the Maximum Battery Capacity of only 98%. This is outrageous, Apple.

Also, it quickly loses charge when in Sleep. 10-15% overnight, easy.

And once, I noticed that it lost charge when it was turned off. I didn't use it for a week or so. Before that I turned it off (I clicked Shut Down not Sleep in the menu). When I turned it on again I saw that it lost almost all the charge. I was shocked. Even my old laptop doesn't lose charge when it's turned off. Its battery degraded a bit but it still holds the charge when you don't use it. So why my new Mac can't do that?

The Diagnostic tool shows no issues, so all I can here from Apple Support is "Batteries are consumable products. They degrade overtime. Yada yada yada..."

I agree batteries degrade but not at the rate of 2% every 20 charging cycles. If this was the case, we would change our phones batteries few times a year.

Shame on you, Apple. Shame on you.

Actually, relative to Apple's claim of "1000 cycles to reach 80%" you're doing pretty well. That would entail a 1% drop every ~50 cycles, so the fact that you got to 62 cycles before it dropped to 99% means you're on a good track so far. The fact that it happened after you upgraded to Monterey could just be a coincidence, because you were otherwise 'due'. Still worth keeping an eye on it though to ensure it doesn't now start dropping faster than it should. Cheers.

You cannot - ever - expect a battery to stay at 100%. That is not how they work. They lose a little all the time and, depending on how you use it/need a little or a lot of power for your tasks - that will happen over time.

The battery in your little alarm clock, portable CD player, or whatever, also loses power and needs to be replaced at some point.

Mine has kept dropping I contacted apple last night and got a case number in the time I was on to them it dropped from 95% to 94% with 81 cycles my advice is contact apple on chat the more of us that do the better
