Hi guys, I am very worried - today my macbook battery started suddenly draining very fast and is now at 23%. It says "battery not charging", although it is connected with the charger. The condition of the battery is normal. I restarted, shut down, left to cool/rest, nothing helped. What can I do? Thank you in advance!

macOS Catalina 10.15.5 introduces battery health management, a feature designed to improve the lifespan of your Mac notebook's battery.
The Battery Health button appears in >SystemPreferences>Energy Saver —this feature is limited to Mac laptops with Thunderbolt 3 ports. That equates to all MacBook Pro models released since late 2016 and the Retina-capable MacBook Air models released since 2018.
With the release of macOS 11.0.1 Big Sur see >System Preferences>Battery
