I found a great way to increase battery life. Get the Juice Defender app. The free version doesn't do too much, but it almost doubled my battery life. It turns off your radios when the screen is off, except for every 20 min (you set) so that apps can update. It also turns off the 2g/3g if you turn on the WiFi.
I now run my phone HEAVY (widgets, live walpapers, etc.) and it still lasts me a day and about a 1/4. Not super long, but with the amount I have running on it shouldn't be lasting 6 hours.
I got it because the first full charge I had I burned through in about 6 hours. I use my phone alot lol.
Cheers
nice............thanks!
