I manage to held the juice up to 24 hours with data packet and wifi not switch at all.
If data packet enabled to synchronise exchange email, gmail and facebook...last until around 7pm maximum.
If surfing with synchronise on, then at 4pm...it will automatically shutdown my application and dim the lcd. Anyway i always unplug it from charger around 7am

i have no idea if rooting the phone can do anything with saving batt. as for me, my phone has not been rooted since i bought it. started playing and testing it for week and battery did drain fast.i did a factory reset as i was just trying to get used to my phone at first. after factory reset i installed juice defender, it did improve the battery life. 2 days average depending on use.
