BlackBerry Curve 9320
Battery life has never been a smartphone strong point. In fact, we often thank the smartphone Gods if we manage to make it home after a day out without a dreaded "shutting down" message interrupting our game of Angry Birds. However, BlackBerrys often hold a little more juice in the tank than rival phones. The Curve 9320 continues this trend, offering up to 7 hours of talk time, or a whopping 30 hours of music playback. Not bad at all.
