here is what i know so far
1. Turn your backlight down to the lowest setting
2. Change to 1xev from global
3. Turn backlight time out to 10 sec.
4. reverse or take out sim card
5. turn off vibrate
6. standby or use clip/holster
7. extended batt(i have the seido oem size and it made a big difference for me after about a month it "broke in" and my batt life is pretty good now)
obviously data and voice will drastically reduce batt life
anyone else have anything to contribute that I am missing...??
yeah, mine lasted apprx. 24 hours on a single charge on .230, i was impressed.. im trying again, just discharged at 10 PM, let see how it lasts all day tomorrow
