MacBook Air Battery Health
I started using my new MacBook Air M1 around August 20, 2021 and today after four months, my battery health has fallen 1%. In these four months, I have not let my MacBook get completely discharged even once (I think it went lowest to 21-22%). Also my average screen time usage is 8-12 hours a day. What charging routine or practices should I follow to prevent my Mac battery health from degrading any further?
Also, I generally don't keep my MacBook plugged in when in use.
MacBook Air 13″, macOS 12.0
