Huge battery drain by "Android OS" when aeroplane mode is off
I'm getting massive drain on my battery when aeroplane mode is off (I have no sim card so when I'm not using WiFi I just put aeroplane mode on to stop it from searching for a network it'll never find) and when I look in battery it shows "Android OS" using 77%. It sometimes loses 15% within minutes. I'm rooted, stock JWR66Y with TWRP.
