One very interesting piece of information that Geeknuz , intentionally?, left out is that the testing from wirelessinfo.com is being redone because they apparently got their hands on a sub-par iPhone and noticed far better battery life in another one. I have been getting pretty decent battery life but it all depends what you are doing and how much you use it.
 
Right now, my battery is fine.

But I only use mine for occasional email, some internet browsing, and looking at picture.

Not much music stuff.

I expect it to last 1-2 days honestly and I will be fine. I charge mine nightly after work
