Hello, Every night I have to leave my phone turned on and plugged in to charging. When I wake up, it shows that it is 100% charged but it always uses some energy then charges it back fully. I think that harms the battery’s life. My phone is iPhone SE. I would like some function like this - when the phone has 80% of battery charged, I would like it to stop charging then I would like it to continue charging when it’s at 40% and so on all the night. Is it possible in any way, like with some special app or charger or any other way?
