MacBook Air m1 battery reduced to 98%

Again, a 1% drop every 3 months will last you 5 years until it reaches 80%, and getting to 62 cycles before it dropped to 99% is actually better than what the batteries are rated for. So at this point you're overreacting, and out of all the people who have posted their battery health statistics in this thread, yours are the least concerning. But again, by all means do keep an eye on it in case the deterioration starts accelerating, as seems to be the case with Geordiedude.

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.

looks like my m1 MacBook is making a liar out of me I said it had stopped at 94% well its now 82 cycles and 93% first ever Mac beginning to wonder about the help they give you because I have just been told its normal

as far as I'm aware when my battery hits 80% and at the rate its going I won't have done 200 charges ill get it replaced or ill be going through the consumer rights as an inherent problem been monitoring since it started dropping

My battery was 97% after I downloaded the CoconutBattery app and there it showed me that my battery is 93%. After a short time in System Preferences it showed me 93% as well. Could CoconutBattery be linked to rapidly declining battery health? I have only 43  Cycle Counts and my battery health is 93%. Battery Health drops from 97% to 93 too quichly. I have been using the laptop for only 8 months. I am totally dissatisfied, because I was always careful how I would use the battery.

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.

Hi because it is used mainly on power it will use that and not the battery but the power will fluctuate as the battery discharges and charges to keep it in good condition there fore you still use cycles but you are lucky that the battery is still 100%

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.

Jack

It lost 2% in 28 cycles.

At this pace I have 252 more cycles/ 927 more days before it reaches the 80% mark (after which even Apple says it needs replacement)

If I'm not wrong Apple claims that count to be around 1000 cycles.

My M1 has just finished 27 cycles and battery health is 96% despite of being careful regarding charge cycle. As by Apple, that after 1000 cycle battery health will be reduced to 80%. But now the speed with which health is deteriorating i think its gonna reduce to 80% just after 120 cycles.

I’m at 87 cycles and 91% not happy

Rechargeable batteries can lose some initial charge quickly and the last for a long time at that level before losing capacity, some will hold initial capacity for a long time and then start to lose capacity, some will start slowly losing capacity from day one, and any other possible combinations.  It is just the nature of rechargeable batteries and no one can predict how any one battery will age.

FWIW, don't try to micromanage your battery and just use the Mac.  If you reach a point in time where the working time on battery is not long enough to meet your needs, then start to worry or just get the battery replaced.

I think this is probably correct. My MacBook Air M1 is currently at 44 cycles / 100% health, so nothing to report yet. But I have an >5-year-old iPhone SE whose battery definitely didn't deplete at a linear rate. It seemed like it took a long time to lose the first ~5% (i.e. a few years), and then it seemed to more quickly drop from the mid-90's to high-80's. But now it seems like it's been at 87% for ages, possibly a year +.

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.

I’m having the same problem with my MacBook bro 2021 M1 pro, and I only have completed 32 cycles with battery health at 98%. I wonder what’s the percentage is going to be when I reach my first 100 cycles!!
