Hi Everbody, I wonder whether is it possible to charge the unit through its external battery connections (five point pins) at the back side of the device, by a compliant DC adapter? My point in asking this questions is that the usual micro USB port loosens and deforms in time after frequent use and you may probably end up changing the port on the chipset which is a nightmare operation. However, the pins at the back side are more solid. Does anybody have any idea? Please don't tell me to buy an external battery cos it's way expensive.
