Just to check if others have this issue. I have MacBook Pro (15-inch, 2018) and occasionally when I plug in Power Adaptor, I get Power Source Power Adaptor. Battery not charging. Switching to another USB C port, or rebooting the mac sorts it.
The Battery Health is good.
It occurred with Catalina and also with Big Sur. Feedback welcome. Phil
This is the new normal— unless you have some wild extreme circumstance which you do not spell out.
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
