I started having an odd issue with battery saver on my ATT 1520 today. My phone was unused on my desk most of the day and when I got home my battery had dropped to 50%, so I opened battery saver to see if something had been running in the background.... I've never seen this before. It doesn't make sense to me, anyone have any ideas? So far I have soft reset twice. The device has been hard reset twice since I received it two weeks ago (warranty replacement).
