I currently reside in a non 4G area, and after last weekend I started to get a lot better battery life, where with my moderate use and saving tips I can get 11-14 hours a day. By the middle of this year I will move to LA, and will definitely have 4G. For those living in 4G areas, how has battery life been once you made adjustments such as WiFi on, low display, gps off and change sync settings? Any possibility that my average hours now remain close to such once I move-or is the 4G very draining? Thanks
