Port could be damaged. Happened to me. I had a car charger that would only charge when wiggled. After a few times charging it, the port broke inside. I got a replacement phone and tried charging it with another car charger, all was fine. After going back to original charger that would only work when wiggling, i needed to do the same thing with the new phone and ended up trashing the original charger.
