MacBook Air m1 battery reduced to 98%

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.

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.

For the number of cycle that I have the degradation is much much faster. My old Mac had some 800+ cycles and the battery health was still 85% . with this new Mac its just 88% in a year. not looking good apple. maybe we are gone have to replace it in next 2 years.

Where did you get that information? Here is a link to the warranty terms:

And here is a link to the costs for out of warranty battery replacements:

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%

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 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'm having the same problem. And very dissatisfied...

My Air M1 bought in April/21, today with 57 cycles, the battery health has dropped to 87%, it's unacceptable. And Apple says it's normal. We all know that the battery is consumable, it will wear out at one time or another, but at this speed it's not normal, and the company doesn't want to assume this design error or batch failure. This week I will take it to an authorized one and demand the replacement of this battery, before the warranty expires.

*** I follow exactly the procedure for using and recharging the battery, according to the company's official article

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!!

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
