MacBook Air m1 battery reduced to 98%

Batteries are considered Consumable Products. Over time it will degrade to a point where it needs to be replaced. In you case - the usage is normal as the capacity will go up and down all the time and never stay always at 100%. Apple Batteries are rated for 1000 Full Battery Cycles and / or 80% Capacity before needing Evaluation or replacement.

For additional reading on Battery and Apple Computers this link may help. About battery health management in Mac notebooks and especially for the M1 and Big Sur If battery charging is paused or on hold on your Mac

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

Simple math:

27 full charge cycles/1000 lifetime estimate x 100% = 2.7% used or conversely 97.3.

So, is the software counting every charge cycle as a full cycle? Only Apple engineers

know what actually counts as a "charge cycle".

If one believes there is a Real Issue >> Find an Apple Authorized Service Provider << nearest your location and have it Evaluated. Just fill in the Country and City information.

IMHO - the explanations provided will prove battery is fine.

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

Same thing happened to me also but i only have 31 cycles Apple should have to listen our concerns

If you truly believe that this is an issue, contact Apple Directly (Contact Apple for support and service - Apple Support) or set up a Genius Bar appointment at the nearest Apple Store or at the nearest Apple Authorized Service Provider and have the Mac evaluated.

BTW, "Apple" is not here. We are just user like yourself trying to help other users.

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...

it's around 50 cycles, and it's only 89% capacity now! It's not sustainable if i run ios simulator + xcode + android simulator , vscode (backend) + chrome with a few tabs opened + 1 youtube video -> which would drain battery significantly! So It's better if you keep it's charging when building sth i guess

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

It's 51 cycle & the battery is already reduced to 90% capacity!

You can try to avoid combo that kills the battery by using some software to monitor your cpu/memory usage

example

• a plugin can cause significant jump in cpu usage
• photoshop + chrome (youtube - a few tabs) + vscode + xcode + ios simulator + android simulator + sidecar -> will kill your battery very fast (100-150% faster than using mac without them)
