Apple took this out of Mac OS somewhat recently. You can try to rely on their power management, but given battery decay is a common reason to buy a new machine I don’t trust them really.

If you have an Apple Silicon Mac I can recommend Battery [1]. It can keep your Mac at 80%, and even force discharge while plugged in to get there. It’s a CLI and status bar utility, I love it.

Thanks, that's exactly what I was missing. I don't know what heuristic Apple's magical 80% charging setting uses but it does absolutely nothing for me, all I wanted is a checkbox for a limit but that's not "smart" and unpredictable enough I guess.

Ooh, thanks for this. There's a similar plugin for Decky on Steam Deck too, in case any SD users are reading this.

...took what out of macOS? It definitely still does "smart charging", keeping it at 80% until just before when it has learned you are likely to unplug it.

If you have a highly irregular schedule, then sure, this may not be helpful. But I find that my and my wife's Apple Silicon laptops are usually kept at 80% unless we explicitly tell them to "charge to full now".

You can’t explicitly tell it to hold at 80% using system settings, when once you could. Glad it works for you and your wife.
