1. Always turn off wireless scanning, Bluetooth when not in use
2. For those not using 3G, choose your network mode to “GSM” instead of “Dual mode” which will consume more battery. Settings -> Connectivity -> Network mode -> GSM
3. Less Display Light
a. Setting -> Phone -> Display -> light sensor (move the slider to the left)
b. Setting -> Phone -> Display -> Light Time-Out (lesser time to save battery but annoying if too short while you are playing games)
4. Always terminate the application properly that is not using by using Option ->Exit. It might be running background and consuming battery which you don’t know.
