What has more than tripled battery life on my DX, is unchecking Background data and Data enabled in Data manager>Data delivery settings. You can still get calls, but your phone won't sync, backup or update. I'll turn it on manually once or twice a day for those! Although I engage in other battery saving strategies, like using Juice Defender, dark still wallpaper, Wifi/GPS/Bluetooth off unless needed, those data settings are the most dramatic!
