The iPhone having poor battery life is nothing new. There are tons of threads on the iPhone forums and all over the web about it. Apple's suggestion is to turn off all location services, bluetooth, wifi etc. The Droid is definitely better in that regard. With my 3g, I depended on my car charger pretty much every day, and especially on those days that I needed the GPS or did a little web browsing. And the 3gs and 3g battery life is comparable despite what Apple wants you to believe. With my Droid, I hardly use the car charger and it works way harder than my 3g did.
