i was about to post the info but it got realy long so i made new post on it so its easier to find
- short version
- turn off 3G
phone screen > ##778 > "000000" > modem settings >
preferred mode- should be on auto as default, switch it to cdma only
menu > commit settings > (auto reboots)
poof 1x only mode!!!
--- also if this is just for battery life, biggest hits are
screen brightness, timeout
gps!,bluetooth,wifi(wifi can help battery in low 3g coverage but dont leave it one when your away)
email pulling ( gmail app with push is much more energy friendly if you can use just it and not the standardized mail program at all
other programs that do constant updating
Edit: oh and vibration uses more energy then audio and can be turned off, also haptic vibrate on selections and notification the have audio and vibrate
