I was referring to charging of the battery being automatically stopped at 80% full. I’m probably wrong, and confusing this with one of /e/OS’s stated goals.
I’ve only charged once since flashing Byzantium; when I noticed that the red light had gone off during charging, I observed the charge was at 78% or so (which I interpreted as battery discharging slightly after charging stopped).
I’ll observe more closely at the next charge and see if it definitely behaves that way. I don’t see anything in the Power settings about limiting charging.
EDIT: @irvinewade, Charged again today. Red LED went out at 85% (That’s 85% according to the indicator), but the phone continued charging just fine. PowerStats shows battery capacity at 100%, i.e. healthy.
