Cycle count has no bearing on battery health. If you'd left the Mac plugged in for 10 years the cycle count would be very low, possibly even 1, yet the battery would still degrade.


97% is very good. Battery degradation is not linear and may stay at 97% for months. It may not.


The metric to watch is remaining capacity. When it gets to 80% Apple recommends you replace the battery for continued reliable operation.


Your battery performance is completely normal. Batteries are consumables and you're seeing that slowly happen as it should
