Why my iPhone 4 does not charge at all?
PLEASE HELP....My phone wont charge.
When it was connected to both the USB and wall charger, the battery icon on the top right did not change. Like it was not detecting any cable connection at all. I found out that the only way it can be charged, is by connecting it to the charger (any types) while the phone is on, switch on the charger and then turn off the phone.
So.. basically, I cant leave my phone's battery to be totally drained out or I'll risk having to buy new batteries each time. Also I am not able to use iTunes anymore since the phone does'nt seem to respond to any cable connections.
I've tried all of these but without any success.
1) changing the battery
2) used different charging cables
3) connecting it to iTunes
4) changing the dock connector
The repair guy did mentioned something about a PMU issue which they don't dare to touch because it may cause the phone to be totally dead.
Is this a good question?
