“Hi, I’ve been using my MacBook for about 9 months and my battery health has already dropped by 6% (now showing 94%). Cycle count is only 72. Is this normal battery aging, or should I be concerned about battery drain?”
MacBook Air 13″, macOS 15.6
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.
FWIW, don't try to micromanage your battery and just use the Mac. If you reach a point in time where the working time on battery is not long enough to meet your needs, then start to worry or just get the battery replaced.

No worries. All is fine, and is common. Unfortunately, there is no way to determine why, nor when, the decrease occurred.
