MacBook Air (2019) battery health

Hello,


I have had my MBA since November 2019.


I use the Battery Health 2 app. I noticed quite quickly my battery health decreased from 100% to 97% (after 7 charges) and now 96% (after 13 charges)

I always charge to 100% and let it run down to around 10%


Is the normal behaviour to lose 3% after only 7 charges? Or have I potentially got battery issue?




MacBook Air 13", macOS 10.15

I wouldn't worry about it.

For first few months these readings will be all over the place.

After few months if you find battery health deteriorate considerably, contact Apple.
