man...on my razor and 8600 i set them just o 1x and dam i have saved alot of battery life..........where i work it constantly switches 1x - ev then no service and i would walk into work with full bars of life at the end of work like 1 bar left. now i still have full bars......its amazing how much evdo drains ur battery life if u work or live in low signal areas.
I have also experienced better battery life with EV-DO turned off on my phones, along with a few other members in this thread. http://forums.wirelessadvisor.com/lg-electronics/62874-how-to-turn-off-evdo-lgvx8500.html
Yep, and disabling EVDO allows you to use your Razr as a wireless modem with no data charges, only MOU (some seem editing may be needed)! CM
