I think sometimes when we are in places where signals are not strong, the battery uses up more quickly because it's searching for signal. I used up almost 50% of the battery for a one and half hour meeting in the basement of my building. The battery drain could also relate to the data transmission on your phone, as I discover. If you have set up sync with your company's server, and depending how you set it, the phone might uses more power than usual. Currently, I have tried to shut down all unnecessary connections, such as bluetooth, wifi where not used.

That said, I am not quite impressed by the battery either. They should do a better job!
