Turn off Bluetooth, GPS, Wi-Fi, and Portable Wi-Fi hotspot when not in use.

All of these features will frequently search for connections in the background while you aren’t using them. To turn these features on and off, go to Menu>Settings>Wireless.

Note: These settings can be accessed quickly by using the Power Control widget. To add this widget, touch and hold an empty space on the Home screen, touch Widget, and touch Power Control.

If Wi-Fi is available, use it: Using Wi-Fi not only saves your mobile data usage, it also can be a more power-efficient way to use data instead of using your mobile network.
