What about power draw when charging?
Has anyone here tried to charge their phone with a car charger while having one of these batteries installed? I've tried two different ones, one from RavPower and one from Seidio, and both of them caused my car charger plug to heat up so badly it started stinking up the car. Touching the plug could cause burns if you held onto it. I was lucky a fire didn't start. It was NOT the phone. I switched back to an OEM battery and it was fine. I also tried a different car charger and the same problem happened with the extended batteries. Charging from my laptop or from a wall outlet didn't seem to be a problem, although I have to wonder if there is still an issue.
