So I just went on a 3 day trip where I spent most of my time as a passenger in a vehicle. I also left my car charger at home, and could only get juice every couple hours at service call stops. Knowing this in advance I did everything I possibly could to preserve my battery. I disabled everything. Sync, Wifi, GPS, etc. I underclocked my droid to 400mhz and set the governor to on demand. I downloaded an app to lower my screen brightness lower than the default value (set it to 2 out of a range of 0 to 255). Turned off background data and was in good service areas the whole time. I was lucky if my phone lasted 3 hours with heavy use. I see people post all the time about their phones lasting all day on a single charge with moderate to heavy use. It is simply not true. This is my second droid and my first one's battery life was just as bad so I know I don't have a lemon. When I say heavy use, I mean I was on the phone the entire time. My brightness was so low that under battery use my display was the 3rd highest culprit and only took 23% of a full charge off of my battery life. I think people whose Droids last all day are using it maybe a couple times an hour and have all their settings tweaked down. I like running my Droid overclocked and with sync on, and if I run it this way I'm lucky to get an hour and a half of moderate use. The Droid battery life is just plain bad.
