How do I maintain a healthy battery health on my MacBook Air 2022 (M2).
My Mac is around 1.5 years old and my battery health is at 90%. Is this normal, if not, how do I improve my charging patterns?
MacBook Air, macOS 14.5
What you are seeing is not unusual and may not even be any indication of an issue.
Rechargeable batteries can lose some initial charge quickly and the last for a long time at that level before losing capacity, some will hold initial capacity for a long time and then start to lose capacity, some will start slowly losing capacity from day one, and any other possible combinations. It is just the nature of rechargeable batteries.
I have an M1 MacBook Air that I purchased when they first came out. After the first year its battery capacity dropped to 90%. Now here in 2024, four years later it is still at 90%.
So, don't worry about micromanaging your battery other than some common sense things like leave it in a car all day in the hot sun in the summer or in the freezing cold in winter (all of which is not good for the computer in general). The only other thing I would suggest is not to continually drain it down to 10% or less before charging.
