3. Use a Black skin with white lettering that permits me to run the brightness at 50% on battery.
4. Poll email instead of push.
5. Set Activesync to run manually so it only runs when connected to USB.

The result is better life than I had on my 6700.

How do you set Activesync to only run when the phone is connected to a USB? It runs at startup for me and I can't find a way to stop it from doing that.
