This sounds like the battery and the charger's problem to handle, not mine.
All this tech, all this automation for every damn thing, and people keep coming at me like I'm supposed to do everything manually with my fingers and eyes and maybe an alarm or something to keep me on schedule. No. Stop it.
Make the charger handle it, or shut up. Make the phone, the charger, and the battery handle it together, you know, with digital automation. Do not even mention it to me.
