My S3 from Sprint recently started to charge very slow, overnight it only got to 86% charge. It was fine before the only thing that happened before it got like that was that it got really hot while I was out with family but I figured it was just because I was using it a lot. It had gotten hot before so that's why I didn't pay much attention to it. I took out the battery and I restarted my phone a couple times I also tried using a different charger and a different outlet but it's still the same. Now I'm wondering if I need a new battery or what can I do?
