My GS3 is giving me inaccurate battery readings or isn't charging at all. I would charge the phone for three hours and it would say that it has a full charge. 10 minutes later I would check my phone and it is down to 40%. I then remove the battery from the phone for a few minutes, put it back in, and now it would say I have a 90% charge. This keeps happening over and over. I took it to AT&T and they replaced my battery. The problem is still on going so there has to be another problem. Anyone else ever have a similar problem, and if so what was the problem and how did you fix it? Thank you!
