Motorola RAZR V3

Cingulair advertises a 7hr battery life and i find it hard to believe such a slim battery could produce such a long life. In your response please state whether you are using a bluetooth headset...i realize that drains your battery much faster and im sure battery testing didn't use this option. And if you are using it on the Cingulair network or using an unlocked phone...they always say network conditions affect the battery as well.

Thanks guys!
