Ive noticed that ever since the 2.1 update, my phone has been using more power during idle than it used to. I have my phone in airplane everday while Im at work from 7:45 until 4, and before it used to stay at 100% battery through that entire time. But now since the 2.1 update, I have been leaving work with only 80% battery left, and nothing else has changed, it is simply in my pocket all day with the radio off. Ive also noticed that phone idle battery usuage in the breakdown of whats using the most battery is now consistently like the 3rd or 4th biggest usage of the battery. Has anybody else had this issue?
