I'd like to explain my problem. I've got an iPhone 4S that was originally from Telus. It broke, the original owner got a refurb unit, and sold it to me. It is currently running iOS 6.0GM, and for what it's worth, it was unlocked properly via the carrier.
The phone has worked perfectly for two months now, no issues. All of a sudden it has developed issues charging. It won't register that it has been plugged in to charge on most cables. I have two separate Apple wall units
and neither of them will charge it. The weird part is that if I turn the iPhone off, then plug it into the USB, it will start up. So obviously something is getting through. One unit has a frayed cable, the other is in perfect condition and both exhibit the same behaviour.
It will charge off my MacBook no problem.
It will sometimes
charge off my USB wall receptacle
. When it refuses to I have to turn the iPhone off, plug it in while it's off, and the iPhone will boot up and charge. If I remove it then plug it back in within a reasonable amount of time, it will continue to charge.
Other than scheduling an appointment at the Apple Store (unfortunately the device is out of warranty), does anyone have any insight or suggestions?
