Unless I don't move the phone at all while connected to the charger (using cable from my previous iPhone 6+) I hear that familiar ding sound that signals the phone isn't charging. I just got the phone a day ago brand new so I can't imagine that there is already dust or something blocking or otherwise inhibiting the lightning port. This sort of thing never happened with my 6+ up to the day before I got the new phone. Is there something wrong with the phone or are the cables not entirely compatible or is there another issue?
