Who’s doing the asking there? Neither my laptop nor my phones asked anything.

According to the settings on my current phone, the automatic setting will decide by itself to limit the maximum charge overnight, then plan to go full charge around the time my alarm should fire.

But, again, that’s the kind of micromanagement that would yield a tiny fraction of “maybe improvement” over the lifetime of the damn thing. I’d rather have a device works all the time for 6 years than have a device that’s sometime undercharged for 6.1 years.
