I had some time today, so I turned on my Droid at 12:15 pm and the battery indicator said I had 80% left. I turned on the phone's GPS, and then started up GPS Status, and went outside with it for maybe 10 minutes. Left the GPS on and GPS Status running. Checked it several times, and at 1:52 I hit 70%. I kept repeating this every once in a while. I hit 60% at 3:50 pm. Right now (right at 5:00 pm), I still am showing 60% battery left.Originally Posted by jackrob
I noted a couple of things. First, I have my screen brightness set about 20% up from minimum on the slider (main screen, menu, settings, sound & display, brightness). I've found in the past that screen brightness rapidly drains the battery, and you don't really lose much usability by turning it down. I don't have a lot of other running services - Astrid, Weather Channel, Battery Status, CallLogService, Assistant (paid app that monitors financial accounts), Shapewriter keyboard, and live wallpaper.
The Home screen for me uses the most battery, probably because of the "live wallpaper" I have installed (maybe I'll take that off...!).
I know when I am actively caching, the battery drains faster than this, but I am sure because I also use the phone as a turn-by-turn GPS in the car with Google Maps, and because I have the screen on for longer periods of time.
