I searched, but found no official instructions on how to do this. I went to bed with a fairly full battery and woke up to a dead phone. My up time is identical to my powered on time. Obviously, I've got a rogue app and my phone isn't sleeping. Can someone give me some step by step instructions to hunting it down? I see SystemPanel referenced here, but is there anything else? I went into the battery properties. The top two listed were cell standby and other system resources so it doesn't appear to be showing up there. Are there apps for rooted or non-rooted users that will show battery usage by app?
