MacBook Air supports such too (at least the M1 model, not sure about

My wife's MBAir M2 with macOS 15.0.1 does not have this feature.

 Optimized Battery charging needs to be active.

Guess what! It is!

If you leave the computer plugged in a lot, then it will charge to 80%
and hold there unless you force it to 100%.  Indeed it will even
discharge from 100 down to 80% according to a website I just looked at.

No it doesn't as long as the Mac recognises you are at home.

"Charging on Hold" will display in the pull down from the status bar.
 If you're more frequently mobile, then it will always charge to 100%.  I
believe (like iPhone) this follows the profile of charging to 80%, then
holding and then topping off on time for the habitual departure time of
the user.

It is exactly vice versa. It does not work at home. Neither with my MBP nor with the MBAir.
That stuff is very poorly implemented.
That also applies to the iPhone.
