my iphone will register its charging when its fully dead. and will charge till it has enough battery life to turn on. but when it turns on it will stay on for about 2-5 min. depends if someone tries to call me or anything.. but i know my chargers are good because i have three different ones, and also tried it in the computer and everything. my phone is not jailbroken or anything. i just dont get why it will charge until it turns on.. help will be very appreciated.
