This is highly variable for people dependant on a number of factors - definitely for anyone out there that wants to try it, you should experiment using and not using push; don't assume turning push off will be an automatic gain. If you receive mail infrequently, push can actually be more efficient. On the flip side, poorly configured networks, firewalls, carriers, or poor wireless coverage, can make push worse than fetch. There's no blanket answer, unfortunately.
You'd get far greater gains in battery life turning your screen brightness down by a 1/4 from whatever your using currently, though
And for iOS5, absolutely minimize the number of apps that are allowed to notify on the lock screen - it turns the screen on every time a notification fires, which is colossally wasteful (and yet another reason why a very discrete notification LED, done super tastefully like the see-through aluminum and pulsing white light on the Macbook Pro, would be ideal ARE YOU LISTENING APPLE STEVE IS GONE YOU CAN PUT THIS IN NOW)
