Why does Apple always think the OS needs to be smarter than the user and then fails at doing so?
I currently want to keep my Macbook Air M1 at 80%, but when plugging it in, it keeps charging beyond 80% to 100% and there is no way to manually tell MacOS to not do this.
You do not have to micro-manage the battery charging.
BHM (battery health management) is dynamic not static.
It would be detrimental to lock your Mac at one specific charging % as you suggest.

Let the software work for you.
The rule of thumb—if you are near the mains leave it plugged in, if you need the portability then run on battery only.
That's it, full stop.
