A:AnswerThat’s a great question, if you can use the phone as it’s plugged into an outlet with the cord and it’s usable like that. Then it’s very possible if if you have a full charged case and it’s on the device you use then it would stay on. As long as the case is charged or charging. But if the phone doesn’t turn on at all with it being plugged in to an outlet before hand. Then I wouldn’t risk buying it. But you could also try and see. Then return if results aren’t what you’ve wanted. Hope this helps
