MacBook Air m1 battery reduced to 98%

I purchased my MacBook Air M1 2 months ago, I have completed 57 charge cycles and my battery health is reduced to 98% even though I have been charging it in the perfect battery cycle between 30%-80%

, never over 80 nor below 30, Why is this happening even after such care of battery.


will letting MacBook always on power with 100% affect battery health even 1% ? I doubt !

MacBook Air 13″, macOS 11.4

it's been correct 5 months now, charge cycle is 105 and my battery health is decreased to 94% now from 98%. At this rate the MacBook life seems very small.


I will update you guys time to time about this issue.
