Apple did a test on mine and found it to be within the operating range they say. They did however discover my farmville app was always running. they said they were goning to contact the dev and see what they could do. They also mentioned my exchange email. Long story short, deleted farmville, and set my emails to fetch and my battery life is great. I can go all day without charging. Last night it was at 49% with 15 hour stand by and almost 5 hours of use. Give it a try you never know. I think the phones are so smart their like people and there isnt just one fix for all phones.
