M1 MacBook Pro Battery Health Issue

Is it normal for a MacBook to decrease in health even while continuously plugged in? I realized my battery health decreasing even when its plugged in. My MacBook 8 months old was at 97% before I decided to keep it plugged in, and now it's 96%. Can someone please let me know if this normal? Also, is it normal for my battery health to decrease that much in the span of 8 months? I am a new mac user. I would appreciate it if anyone could guide me on this issue.

MacBook Pro 13″, macOS 11.4

That is normal.


Battery Management.

How battery health management helps

The battery health management feature in macOS 10.15.5 is designed to improve your battery's lifespan by reducing the rate at which it chemically ages. The feature does this by monitoring your battery's temperature history and its charging patterns.


Based on the measurements that it collects, battery health management may reduce your battery's maximum charge when in this mode. This happens as needed to ensure that your battery charges to a level that's optimized for your usage—reducing wear on the battery, and slowing its chemical aging. Battery health management also uses the measurements to calculate when your battery needs service.
