Does anyone know why this keeps happening to me? I literally just leave my phone on my desk, and sometime during the night the battery randomly plummets. This happened once before in the past week. I think it has something to do with Google Plus because, aside from streaming Pandora in the car, I barely used my phone yesterday. This is new, which makes me think it has to do with the 4.4.2 update or some app update. Based on the timing, I think it starts at around 1 in the morning.
