I don't know what is going on with my phone. I had my galaxy s4 for about a year and it was working fine. I noticed the battery was draining faster than usual, so I brought a new one (not stock). The new one was charged up to 100 percent, I left it in the phone overnight and turned it off. I turned it back on the next morning the battery was at 38 percent. I sent that one back. I brought two new batteries, different brand again. One of the batteries did the same thing as the last one. Tonight I'm trying the next battery in my phone overnight, phone off again. I went to Radioshack and they don't have the stock battery, the guy said it could be the phone or the battery.
