I have had this iphone for like a month and It has worked perfectly in till 3 days ago. I charged it and went to turn it on but it wouldn't turn on. So i pressed the power and the back button and it reset. Then it would stay on for like a minute and then totally turn off and I would have to reset it again. I plugged it in my computer and it worked perfectly?! I don't know if its a battery shortage or something but I don't get it. It only works on the charger…
