Switch off screen when not in use
Setting a short LCD light time-out or auto locking time-out will help you to save significant amount of battery power too. Combine this with the lowest screen brightness will gives you the most significant / visible savings of your battery power.

Use 2G instead of 3G
Although the difference is not much in terms of standby time but it is more significant in talk time.

Switch off Bluetooth and WiFi Scanner
If you don't need them, switch them off.
  • Menu > Settings > Connectivity >  Bluetooth
  • Menu > Settings > Connectivity > Wireless LAN
Running Applications
Again, if you don't need them, exit the applications. Don't leave them running in the background.
