iPhone 3G and 3GS battery test: iOS 3 vs. iOS 4 | Phones | From the Lab | Macworld
The iPhone 3G with iOS 4 lasted 5 percent longer (10 minutes) than the iOS 3-configured iPhone 3G. That’s not a big difference, but frankly, I thought battery life would decrease, not increase, after updating the OS.
In these tests, there was an even greater increase in battery life with iOS 4, with the updated iPhone 3GS lasting 14 percent longer (35 minutes) than with iOS 3. This time, downloading our rented movie took less time in iOS 4 than in iOS 3.
Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).

Well each OS update is more optimised then the last. And that's understandable. I think it's a bigger difference then 10 mins but multi-tasking brings that difference down to 10 mins. Which in my opinion is rather good.
