I think I know the answer to this, but I am assuming auto sync needs to be on in order to receive push email from gmail. Is that correct? I am experimenting with my battery and trying to find ways to extend it (that's what she said), but want to know if I'm wasting battery energy having auto sync on. Also, for those who are getting great battery life, what are your settings. I have GPS off, wifi off, BT off, screen turned all the way down, timeout set to 15 seconds. I have facebook, fox news widget, weather widget with a clock.
