I just thought I'd relay my experiences with battery life. Up until now, I had Windows Live Hotmail set to deliver emails immediately, "As items arrive". I would unplug my phone in the morning at about 7am with 100%, and it would be down to 15% or less by 9pm. (Worse if I actually did some heavy usage). I recently decided that I didn't really need to get emails instantly. I instead set it to once every 15 minutes. Now, at the end of the day, my battery still has about 50-60% of its charge!

So moral of the story- push email is a HUGE drain on battery life.
