I should have posted this up a few days ago, but I was running my settings just to verify. For a while, I had issues where my Droid only lasted about 9-12 hours before dying. I couldn't figure it out - I had GPS, WiFi, and Bluetooth off. I had the screen brightness set to the absolute minimum for the entire day. I even installed Locale to turn off AutoSync automatically for 5 hours a day. Still, I kept getting horrible battery life (at least nothing close to what was boasted in the Droid specs). Then I found Spare Parts in the market place. Before I installed the app, I thought it was Gmail and the Calendar that were draining my battery. I even removed all of my widgets to help the Android. After I installed the app, I found the culprit - Meebo IM (or any instant messaging client for that matter). Anyway, I solved the issue by leaving myself logged off of Meebo or eBuddy, and using Advanced Task Killer to ensure they are "dead." The results? Over 1-2 days of battery life, with extensive phone use, text messaging, internet use, Market use, some music playing, and maybe some Google Maps Navigation. If you need to figure out what's killing your battery, download "Spare Parts" from the Market. Once it is installed: 1.) Open the app 2.) Click on "Battery History" 3.) Click on "Partial wake usage" This should then reveal what app or service is consuming the most resources when your phone is idle. Give it a try. It's not just a battery app, but also a settings app. I hope this helps some of you.
