i have an iPhone 4 which appears to only work on the charger. as soon as it has been removed from the charger it turns off. and you can’t do a thing with it unless on the charger. i was just wondering what the problem is, how to fix it, and what part/s i need. i hope you can help!
I have the same problem…..apparently is a bad battery or bad dock connector. I haven’t had the time to try and fix it. So what I suggest is take your iPhone apart and reassemble it, to make sure everything is as it should be!
Try replacing the battery. It’s a relatively cheap and easy fix and seemed to help my iphone 4. Good luck and hope it helps!
