Might depend on how you use it. I don't use GPS for navigating, but I have occasionally used a tracking device which records where I've been (I use it much more on the bike actually). That doesn't really sleep and I don't get much more than 6 hours out of an iPhone battery with it on, even in airplane mode. For that reason I don't really bother with it on the hills anymore, and if out on a long bike ride (70 miles +), I need to take a spare battery pack/charger for it.
If you are just using an app to see where you are, it could be quite different.
