Of course the iPhone has better battery life. It doesn't have a large screen and a 4G radio sucking the life out of it. That's more than likely why the 4S is not 4G capable because Apple knows that without a removable battery the iPhone will become an expensive paper weight.
I have a 2750 mah battery in my Thunderbolt and I only get a day out of it before it needs charged. The iPhone 5 won't be 4G because by next summer I doubt they will have solved the 4G battery sucking problem and Apple will not stick a 2250-3000 mah battery in it because it would be gigantic.
