@Ken Maltby: that's how I vaguely remembered it, too, thanks. [And how I remember the refresh behavior being implemented].
@roger64: So, basically, you were expecting an always-on battery status *somewhere*, is that right? Or at the very least *something* always visible when the battery is charging? Because as Ken just confirmed, KOReader handles battery status refreshes the exact same way whether it's charging or not, so I'm a tiny bit confused, and not quite 'getting' what behavior you were expecting
