So I got this iPhone 6 Plus from a friend after my iPhone SE screen crashed. The phone is secondhand and I've had it since June 2017. Recently it's been dying on me quickly, especially if I go on snapchat. On friday night I had it on the charger then woke up, tried to use it, but it showed the red battery icon as if it died. I waited for it to turn on and it never did. I tried charging it from my laptop, in the car, and from other chargers but nothing is working I watched a video that said heating the phone up with a hairdryer would most likely fix it so I tried that but only heated it up for a under a minute because I didn't want to completely fry the phone. Does anyone know of any way for me to bring the phone back? Can't afford a new phone or battery replacement for a while so PLEASE HELP :crying:
