Funny i had a similar problem when i was messing around in those menu's i remembered experimenting with the wr battery i believe it is #70 in the menu's it was set for 171 and i put it to 250 and with in 20 minutes i noticed a huge difference but i was playing with everything so i had no idea so i brought the phone to verizon they said my battery was dead so they gave me a new one. I was happy but on the way home my other battery died. So it took some real convincing for my wife to play with her phone and sure enough that setting was changed so i changed it back to 171 no more problems hope that helps you.

after looking around in those 'secret' menus my battery life has died. i will goto sleep with my phone next to me (for alarm) and it will die before i wake up. i went to the debug menu, gps settings, and checked out the LED colors. i couldnt do anything in the GPS menu cause i kept getting "gps locked" message. messed around in the debug menu but i dont think i changed anything. any ideas on why my battery life dropped?
