This happened to me, twice in fact. I think has has got to do with the power outlet where you are. Are you using a splitter? It could be causing the problem.
It also only happens when I'm using it, most commonly when playing games or some type of hardcore use.
Try a different power outlet in the building or a power outlet in a completely different building.
I think it's a problem with the power outlet, not the phone or any accessories.
