Starting with macOS 10.15.5 Catalina, Apple introduced a battery health management feature that improves your battery’s lifespan by adjusting charging patterns to reduce the rate at which the battery chemically ages. (Find it in System Preferences > Energy Saver > Battery Health.) One thing to be aware of with battery health management is that it might cause your MacBook to display “Battery Is Not Charging” in the battery status menu even when it’s plugged in. That’s normal, and it’s nothing to worry about. Of course, if you regularly see that message, it’s a hint that you may not be using the proper power adapter and cable or that the power source isn’t delivering enough juice.
