How to increase Samsung Galaxy S3 Battery Life

The most important thing when buying a smartphone is the battery life.. So, How to increase Samsung Galaxy S3 Battery Life ?

No point buying a great smartphone but the battery will only last for few hours..

Especially when u’re on call during night duty, the last thing u wish is ur phone battery flat & the nurses cant get u..

Now to improve battery life, few tricks as mentioned below:

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.

Adjust screen timeout duration

Reduce the screen timeout duration will increase your battery life but bear in mind if u want to read books with ur S3, u will get frustrated but the screen timeout.. so adjust according to ur own needs

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.

Otherwise, u can buy extra battery to replace it when ur juice run out..

For me, till now its still acceptable.. 100% at 7am & on 3G whole day, back to home at 7pm with 30-40% left.. Used calculator & browser most of the time..

If off 3g, 12 hours only will suck around 10-20%

Anyway, I hate branula bunk!
