3G phones have super-fast data and super-low battery life. DoCoMo says they figured out how to extend battery life without compromising features. The new phones which are made by Fujitsu and NEC, will run for 200 - 240 hours. That is a big improvement from the the 170 - 180 hours of standby time on DoCoMo’s older 3G phones. We’re still skeptical. When was the last time a mobile device really lasted as long as it is supposed to? It’s almost a game with consumers.
