says fully charged buy dies when charger disconnects
I have recently been given an iPhone from my dads collegue to sell for myself. It is a GSM iPhone 4. I plug it into a charger and it boots up to a DFU/slide to SOS mode but the charging image says it is fully charged. when I unplug it, it shuts off immidiatly and dies. I replaced a battery from another phone and the same problem happened. I then plugged it into my PC but then the apple logo turns on and off. I have fixed way over 50 iPhones and I have never seen such a thing.
Anybody know of a soulution?
Is this a good question?
