These past couple days my iPhone has been overheating and the battery seems to last about 2 hours. I've had to charge it 3 times today. I don't use it that much. I close all my apps and disable all unnecessary settings that I don't use and it still drains. My phone was at 90 percent no apps were opened in the background I look at it 5 minutes later it's at 83 and it's hot. Should I go to Apple and replace my battery?
