> discharge to 80%, keep it there Where? AFAIK this is a feature you need a third party app like Aldente for. The OS does not offer any way to control battery charging level. Yes, it tries to be smart and guess when you need full charge and sometimes decides to charge to only 80% but that doesnt work for all users except the ones with very regular routines and there is no manual control.

I meant the automatic one. My charge cycles are not very predictable, but periodically my Mac says that It'll hold-off charge, and uses battery until 80%, then uses power adapter. Then charges the battery fully later in the day if I'm connected. Sometimes it flat out refuses the charge. Then I disconnect and use the battery until 30% or so. Then charge when convenient (clarification: It'd possibly charge if I hit a certain percentage, but I always disconnected voluntarily, to give a good use to battery. I lasts a day. Why not?). My MacBook Air M1 has 165 cycles in 3 years, at 90% of design capacity. I think this is a very solid management of the battery for a computer used every day literally. My MacBook Pro is at ~85% after 8 years. I don't remember total cycles now.

    I generally do mundane tasks like SSH sessions or zoom meetings when I'm on battery. Heavier tasks are always offloaded to my desktop system, most of the times, so running on battery here and there doesn't impact many things in my case.

      A video call though isn't that mundane. Google Meet often has my cpu and fans spinning. I do prefer Zoom as it uses fewer resources. But of course, it will work on battery.

        For an M1 powered MacBook Air, none of them creates a significant power spike on the system. I use both regularly, generally one hour at a time, and battery percentage doesn't take a noticeable hit after the call, and the computer doesn't warm up.
