Over the past couple of days my iPhone's battery has been draining really fast. For instance the other day I went to class with my phone almost completely charged and by the time I left the class an hour and 15mins later, i got the 20% remaining popup, I was a little confused but didnt think too much of it, so i put music on and within a couple of mins (2-3) the 10% remaining popup came up, so I immediately turned the phone off and when I got back to my dorm I plugged it in and charged it fully. I thought that I knew the reason for this, my school was experience a problem with the wireless with it connecting and disconnecting throughout the day, so I thought that could of have been the reason. But then it happened the next day as well and there was no problems with wireless. So this time I turned the wireless off and it was good for a day. Today it was charged all day and I did not use it much at all, about 10 mins ago I go and pick it up and the battery is down to 20% again, and the wireless is off, and I do not have push notification on for my mail so I do not know what is draining the battery so quickly. If this has happened to anyone else or if anyone knows what might be causing it, I would appreciate hearing from you! Thanks!
