How to increase Samsung Galaxy S3 battery life?

Turn on all Power saving settings
Samsung Galaxy S3 has several power saving settings like CPU power saving, screen power saving, background colour and turn off haptic feedback. Turn on those that acceptable to you only because performance will be decreased and user experience will be affected too.

Reduce display brightness
By default, Samsung Galaxy S3 has lower auto brightness value. This help to improve battery life as HD Super AMOLED eats lot of battery. However, you can further improve by set brightness to the lowest level that acceptable to you.

Remove unused widget
Widgets are nice on Android. But they are battery eaters especially those widgets that use data connection and auto sync based on schedule. Therefore, only keep those widgets that you really need.

Poor signal decrease battery life
Phone will use more power when signal is weak because it uses more power to increase signal strength. Always make sure that your phone has a good signal reception. Switch to 2G if 3G connection signal is poor at your area.

Use Wi-Fi when available
Always gets connected with Wi-Fi when available and turn off 3G data connection. 3G data connection eats more battery compare to Wi-Fi connection. Turn off both of them when not needed.

Disable / reduce auto-sync
Data connection eats battery life. Disable or reduce background scheduled auto-sync applications like Gmail, Twitter. And reduce the frequency of auto-sync will also help to improve battery life too.

Turn off Bluetooth, GPS
If you don’t use Bluetooth or GPS, turn them off. Turn them on when needed only.

Turn off motion sensor
Samsung Galaxy S3 has lot of Motion features like Direct call, Smart alert, Tap to top, Tilt to zoom, Pan to move icon, Pan to browse images, Shake to update and Turn over to mute/pause. Only activate those you need.

Use solid black static wallpaper
Samsung Galaxy S3 HD Super AMOLED uses less power on solid black wallpaper because less backlight is output. And try not to use beautiful live wallpaper. Why? Lovely animated live wallpaper costs you more CPU power usage == lower battery life.

Fully close application that not use
SGS3 is a great multitasking machine. But by letting lot of applications running at background actually increase battery usage because they still require CPU processing. So fully close those applications that not needed. Example, GPS navigation application.

Disable unused built-in system applications
You can disable Samsung bundle software like ChatON, S Voice, Game Hub if you don’t need them with Android 4.0 Ice Cream Sandwich disable application feature. Why? Some of them are running as service even you are not using them at all.

Undervolt and underclock CPU
Besides display, SGS3 CPU is the second biggest battery eater. If you don’t need 1.4 GHz processing power, underclock it. And undervolt Samsung Galaxy S3 with SetCPU.
