3: Exchange Active Sync *deliver items as they arrive* This seems to use alot of battery, but I am not sure yet since my own personal battery drain may have had to do with the camera app deal and my hard reset over the weekend.

#3 is a PIG! I have switched my synching to every 30 minutes and I can get 2 days out of my 680. If I set the Active Sync to "Deliver items as they arrive" I can get 6-8 hours before no power. Battery graph shows that under those conditions, the phone never goes to sleep.

I'll look out for TGP.
