I just got my 3G. Funny but in the days preceding my older iPhone wouldn't make it through the day on one battery charge! Damn it to hell. Seemed also to be highly variable. When I got my 3G I brought my charger into work and braced for a recharge midway through the day. To my surprise my 3G easily makes it through a day with, I mean from my wake up to sleep, with no recharge.
There was only one significant difference in my settings. I know this because when I set up my 3G I restored from a full backup of my original iPhone and only changed the settings for my two email accounts to 'Fetch' every 15 minutes. Before that they had always been set to 'Push'. (Click here for an earlier post on this topic from Jeff Mason.)
So my 1G had much poorer battery life, usually fizzling out by afternoon, when my gmail and Exchange email accounts were both set to 'Push'. But my 3G with all other settings equal, except the two email accounts set to 'Fetch' every 15 minutes lasts an entire waking day.

Congrats on the new 3G!

I found that I can keep Push on and still get great battery performance if I leave 3G off - and only turn it on if I need it
