User level: Level 1 (4 points)I bought a brand-new MacBook Air M4 about two months ago. The battery cycle count is currently only 10, but the maximum battery capacity has already dropped to 96%.
I have had the charge limit set to 80% since day 1, and most of the time the MacBook is connected to power through a dock.
Is it normal for the battery capacity to drop to 96% with only 10 charge cycles and around two months of use? Should I be concerned about the battery health?

It's not unusual.
Should I be concerned about the battery health?
Would it help?
At your option you can contact Apple, but they won't be interested unless the battery is defective, and that one is not. They'll tell you what I just did.
