I've had an iPad Air since Thanksgiving weekend. I love it. It's been perfect, especially with its battery life, getting at least 10 hours of usage, sometimes more, across multiple days. It's been wonderful, compared to my iPhone. However, recently, I've noticed some strange behavior. When I do certain tasks, such as FaceTime or steaming video, my iPad Air gets hot, and the battery drains very fast. Right now, the stats are about 5 hours and 15 minutes of usage with 12 hours and 13 minutes of standby, and it's at 26%. It's almost as bad as my iPhone now. I spent about 40-50 minutes of streaming video and 50 minutes of FaceTime this evening before posting. I have used FaceTime in the past, before this week when I experienced it getting warm, and have not had heat problems nor battery problems. I haven't changed anything in the Settings, I have everything on. Everything was on even when my iPad was getting amazing battery life that I mentioned earlier.
