Brightness keeps changing on M1 Macbook Pro / Big Sur 11.1

Just got this new Mac Book Pro M1 and I've noticed an issue with the display brightness. I set it to a 90% level and after a while I notice that it has gotten darker. The brightness setting then shows a lower level. I've unchecked the "automatically adjust brightness" setting on the Display panel. Don't know where else to look. Did not have this issue on my older MBP with Catalina.


MacBook Pro 13″, macOS 11.1

I don't know if this is what you are seeing… Open System Preferences > Battery > Battery. Try unchecking "Slightly dim the display…".
