So I tried putting the phone on airplane mode overnight to preserve the battery but it still shrunk at least 40% overnight. I had wifi, gps, brightness, all of those were off. I tried the idea where you turn the phone on airplane mode than shut the phone off, turn the phone on and shut off airplane mode but that doesn't seem to be helping. Obviously I didn't touch the phone overnight, so what is draining the battery? The battery use page said 54% phone idle and 46% cell standby. I'm just getting tired of having this thing in the charger so much. I rarely even used any apps or the browser yesterday. Why is it draining!?
