The iPhone 4 has the best battery life of any smartphone that I have had so far. I'm getting 7 hours of usage in a little under a 2 day period: :)

3G ON
WiFi ON
Bluetooth OFF
Location Services ON
Push Mail OFF, Fetch hourly ON.
Auto-Brightness ON, and set at 75%
My usage: Voice calls, messaging, Safari, iPod player,
Navigation, Weather & News, YouTube, Camera/Video, and email.

Standard usage (some radio streaming, watching some videos, internet over 3G, some games and some calling). Battery of i4 is a huge improvement over the 3GS.
