This sounds like U2 IC damage, this happens when you use cheap third party cables and chargers etc. It can also happen when charging the phone in the car. This damages the U2 IC which controls charging, syncing etc. When this is damaged, it can have a few symptoms: - over heating - fast battery drain (even in airplane mode) - Charging when device is on, but not when powered off or dead - giving the "this cable or accessory is not certified" message, even when using an original cable Only fix for this is replacing the U2 IC chip, which requires microsoldering.
