So just came back after a 15 hour shift at a place where there is NO voice/data signal (well maybe get 1/2 bar or so if I stand near a window which there aren't many). I still have 1/2 the battery left. Couple of things I did:

** Kept 4g AND 3g data off while in the buildling. Connected to the local wifi in the building to use data and groove ip for voice (and ?text). Worked well. Usage was about medium (i.e. wasn't on the phone the entire time, but did get on and off for various apps, web surfing, etc.
