Battery health drop from 98% to 97% within a week on MacBook Air M3

I purchased my MacBook Air M3 on October 30, 2024. Currently, after 76 charge cycles, the battery health shows a maximum capacity of 97%. Last week, it was at 98%, but it dropped to 97% within a week. Is this normal, or should I be concerned?

That’s normal. Battery health decline is not linear. I’ve had Macs stay at 100% for months, but typically they drop to 88-92% health over the first 100-200 cycles then stay there for several hundred more cycles before beginning to decline. Apple’s threshold for concern is 80% health.
