I have a Galaxy SIII that is not holding charge and the battery will over heat at times to the point where you can barely hold the phone. I replaced the battery with my wife's phone battery and the same thing happened. It is able to drain a battery in less than 10 hours w/o using for hardly anything. Can this phone be replaced? I still have 8 months before I can upgrade. It doesn't help that the signal at my home sucks even though the map states we are in a great coverage area.
