Day 2, Full Charge AM, ear buds plugged into Nokia BH-214 & playing music all day on random, running wifi/gps/BT and no auto syc. After a full day of work approx 10hrs, battery was at 40% +/-

Day 3, Full Charge AM, no earbuds or music, running wifi/gps and no auto syc. Doing server admin work and some light gaming. After a full day of work approx 10hrs, battery was at 80% +/-

Day 2, Full Charge AM, ear buds plugged into Nokia BH-214 & playing music all day on random, running wifi/gps/BT and no auto syc. Bunch of calls, and playing Asphalt 6 HD for about 4 hours. After a full day of work approx 10hrs, battery was at OMFG CHARGE ME.
