Iphone 3GS - Battery Life

Hi Folks,
Good morning!..I am a new member and joined this forum recently since i have switched my phone from a Nokia 6300 to Iphone 3GS (16GB). I should say that this forum is really impressive, coz i was watching/reading this to get a feel for the place.....I am writing to enquire if anybody can advise me on my new I Phone 3GS. I am on O2 network in Dublin, Ireland.
It’s a month old phone and i can see that i have to charge my phone almost every 30 hours or so.....i am giving the statistics of the phone for your reference....
Settings:
Wi-Fi – Off
3G – Off, Working on Edge
Fetch – Off
Brightness – Auto
Lifetime - 2 Hrs and 33 Minutes
Current time – 2 hrs and 33 minutes
Cellular Data – 1.7 MB send and 2.3 MB received.
Usage – Normally i get about 33 minutes to 35 minutes maximum before next recharge.
I am really puzzled, is this quite normal with Iphone 3GS....please advise....

I have the exact phone. My battery life was really bad in the beginning too. I just let it completely die a few times in a row now I can go maybe 3-4 days on stand by and get around 4-5 hours talk time along with ipod and internet usage thrown in

maybe it will help if you let it die a few times.

Thanks for the advise, i might try to do this....to let the battery drain dead a couple of times before i go for recharge...regards

And of course welcome to the forum, unnisuchi.
