First off let me say that I've looked around and can't find specifically the same thing that's happening to my phone. Maybe I'm not looking specifically enough... So I changed some settings recently to help with my battery life though tips I found on here, such as setting my syncs to up to the following: Facebook: Update once a day Sync live feed is OFF Sync contacts is ON Google: Sync Calendar is ON Contacts is OFF Gmail in ON News: Sync is set to MANUAL Stocks is OFF Weather is EVERY 3 HOURS Tried a little experiment last night. Charged my phone through USB to 100%, then disconnected and let it sit overnight so I could see how much juice it used while idle. I used my Power Control widget to turn everything (WiFi, Sync, etc.) off before going to bed. Woke up 6 hours later and my battery was surprisingly down to 39%. I used ShootMe to take some screen shots of what the Spare Parts app showed me: I don't know what that "0" is in the above picture (or that UID 10006 for that matter), in fact, I don't even know what blue vs red bars mean. I tried clicking on the "0" bar, and I get a this FC message: "com.android.settings" doesn't yield any search results on Android Forums. I'm going to do some more research. I didn't see anything about this in the official battery thread either, but I'ma keep looking. Any insight would be helpful. Oh, and FWIW I haven't updated my software yet. Waiting for the phone to prompt me to do so rather than looking for the update myself. Not totally convinced I'm not going to end up with a shiny new brick.
