MacBook Air m1 battery reduced to 98%

Any update Geordiedude? My battery health finally dropped to 99% after 53 cycles, and now after 54 cycles it dropped to 98%, ha!

I saw in the recent macOS 12.3 update "Battery capacity readings have improved accuracy" and thought to myself maybe this whole issue was just a software glitch that Apple has now fixed; but that was before my battery health dropped to 99% and then promptly to 98%, so I guess not. My 1-year warranty is already expired at this point, so I'll just hope for the best!

My MacBook Air m1 just have 24 Cycles and the battery help is in 98% in worry because my device is always plugged, I’m work in my house and still making cycles and the battery is degrading , this is normal ?

Even I was having this problem with my 2012 13” inch MacBook Pro. Last week it showed me a warning message that the battery to be replaced. When I checked the maximum capacity was 72%.actually it is good for 9 years of heavy usage. I recommend not to replace battery until it comes to 50%, because even it still runs absolutely great

I have same problem with my m1 macbook pro 2020 model, the cycle count is only 59 and the maximum capacity 91% , where else I have seen people with more cycle counts having 100% capacity!

Why is that? Can anyone enlighten us?

I bought my Macbook air M1 almost 2 month ago. Condition: Brand new. Cycle count reached 21 and my battery percent is now 96%. The first battery drop happened after around two weeks since i bought my mac. And since on, battery keeps dropping. But in usual case, at least 20 cycle should have caused a 1% battery drop only! I basically follow the rules regarding right care of battery, but does not help. Is it normal??

Well, what did you send it in for? They won't do the battery automatically unless they need to remove it to get to something they need to repair OR if it's the battery itself that you sent it in for of course. But yes, if they have to remove the battery to get to another component like the trackpad or remove the logic board they'll replace the battery since it's in the way so to speak and is also glued in (adhesively). You'll see an itemized list of what they did when you pick it up.

My 3 month old M1 Pro 14" 10-core has 22 cycles on it and is at 97% capacity which is kind of concerning. I have Applecare and all that so no big deal but it should be at -3% capacity after only 22 cycles either....hmmmmmm

Interesting...

My 3 month old (actually 2.5 month) M1 Pro 14" 10-core 16GB/1TB has 22 cycles on it and is at 97% capacity which is kind of concerning. I have Applecare+ so no big deal but should it be at -3% capacity after only 22 cycles? Seems Seems like it should still be at full capacity at only 22 cycles and 2.5 months...hmmmmmm

Could you please tell how many hours of battery backup your mac is giving now and what was it before.

Because everyone is concerned about the battery health but I have not heard a single person talk about the battery backup and what is the result after they got battery replacement.

its not really a problem, don't worry about it. If you do the math the amount of cycles you used / 1000 is about 98-99%.

I would just be careful with the amount of times you charge your device. I use ALdente to stop my M1 Pro from charging past 55% and to depend on the power supply if I am working on a desk for a long period of time.

I have also the same problem, in two months with a 38-cycle count, the battery was reduced to 98%. Apple support is not satisfactory. Even on this ratio of reducing, the battery needs to change in some time. Even Backup is also reduced to 6-7 hours. I think there is issue with battery of Macbook Air M1.

Even I am experiencing the same problem with just 27 cycles. There is definitely some problem. I guess apple is playing with my customer rights and policies.

i also experienced the same thing i think apple m1 macs has battery issue

I have the issue as well I got my m1 air 5 months ago and now my battery health is at 96%, I think there is some issue with battery health in m1 MacBooks. Hope apple will listen and look into it. "_"

Mine drop to 94% i need replacement

The behaviour you describe is normal. Please review Check the condition of your Mac notebook’s battery - Apple Support.
