MacBook Air m1 battery reduced to 98%

I’m on Monterey and wondered if that is why mine was dropping but it seams to be a problem I contacted apple and was told it’s normal and if it gets to 80% get in touch it seams wrong to me

you can disable hardware acceleration mode in Chrome as it may help a bit

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".

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)

...

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%

Interesting. You'll have to see if it now starts dropping precipitously like Georgiedude. If so, you may have a problem.

Overall it's a bit ironic that if it weren't for Apple introducing these battery metrics a few years ago in the first place, none of us would even be able to obsess over this stuff—it used to be that we had no clue what the status of our batteries was beyond being either 'normal' or 'service required'.

Incidentally, I have a nearly 5-year-old iPhone SE with the battery health currently at 87%, and it definitely hasn't been a linear decrease to this point. Seemed like it took 2–3 years to get down to 95%, then it seemed to drop quite a bit faster from the mid-90's to the high-80's, and now it's been at 87% for several months. And my daily usage hasn't really changed throughout all this time; so it seems like it's hard to know what to expect.

At least the macbook m1 air has 2 HUGE design flaws:

1. The screen almost cracks on its own
2. Battery capacity decay at very fast pace

I had these problems and Apple replaced both battery and screen free of charge under normal warranty. I was problably lucky that i'm in UK (european laws) otherwise I would have had to pay for repairs.

So Apple knows it's their fault but they hide the problem and make us pay for their mistake.

THIS IS OUTRAGEOUS!

Now, after this experience I was left with sequelae... the laptop is always plugged in and I close/open the lid with really ridiculous attention.

In 5 months the warranty will end and I will be out of luck so I will sell my macbook air and return to pc after 13 years.

I'm out of patience with Apple, i had problem with 2011 17' mb pro and his AMD gpu problem, been 3 times in service to replaced it. After that with my wife's macbook air sticky keys.

So thanks Apple or not!

CoconutBattery just gives you more detailed insight into your battery. It shouldn't affect it in anyway. It's constantly fluctuating for me. I'm at 92.3% now, was 92.9% earlier today and it'll probably be up to 94% tomorrow. I just like it because it's an easy way to see your cycle count and the remaining charge capacity of the battery.

That said, I'm at 29 cycles and down to around 92-94%. Not great.

I doubt others' answers. My M1 Air is just over 4 months old. Been running almost every day for 9+ hours, of which only 1-2 hours are on battery, and for the rest of the time it's always plugged in. Yet my battery health remains at 100% with 63 cycles.

Bought one on September 29, 2021; staying in the 30-80% range (strictly).

Days I have used it for (counting today)- 103

Cycle count- 28

Maximum Capacity- 98%.

I am worried.

Your Battery Health is fine.

i have a m1 macbook pro for 6 months, with only 20 cycle charge, the battery health drop to 99%. as most of the time i plugged in to adapter. the battery isnt what it claimed to be 20hrs from 100 to zero. in abount 4 hrs it used 45% with only 1 safari tab with youtube running, and it still can do memory swap even on a 16GB with 2TB.

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. "_"
