Reduce battery consumption on iPhone 2.0 phones

I don't have the latest firmware (quietly released only when a restore is performed), but a lot of people have been complaining about abysmal battery life for the 3G iPhone (four to six hours). After a lot of trial and error, disabling push mail and only checking mail hourly has greatly improved battery life.
With wifi, Bluetooth, 3G, and GPS enabled, battery life is is more consistent with the first generation iPhone. A quick check of the Apple support discussion board reveals that others are coming to similar conclusions.
[robg adds: Disabling push email on first generation iPhones running iPhone software 2.0 should have similar benefits.]
