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

In you case - the usage is normal as the capacity will go up and down all the time and never stay always at 100%.

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
Mine decreased much faster than yours, it became 99% after two weeks
Cycle count 28, and maximum capacity 98. I bought my Mac in July, and I care it better than my wife. Why ıs that happen? Apple explain, is it normal?!
98% with only 30 cicles
Any updates?
