iPhone 4s will not turn on
One of my iPhones turned itself off the other day. We tried turning it back on with no success. I plugged it into my computer and it said it was in recovery mode. I restored it to factory setting and updated it. It was almost done updating, it said waiting for the phone, it continued to wait for the phone for an hour. I unplugged it and the phone lost power and would not turn back on. Battery was at 60%. A day later we tried to turn the phone on and it worked. It is my nephews phone, he used it for a day and then the same thing happened, it shut down and would not come back on. I plug it in my computer and it turned on. When I unplugged it, it stayed on for about 10 mins and the shut down(battery was at 70%). Now there is nothing when I plug it in to my computer or the charger. I tried to turn it on and still nothing. It is plug into the charger now. I don't think it was exposed to any water, but he does drop the phone once and a while. Any suggestion what might be wrong. Thanks Danny
Is this a good question?
