If you play games and stream videos regularly, text frequently, or use these applications all at the same time, then you should not be surprised when the battery indicator turns red.
Even if you are not actively using any application, the Samsung Galaxy S3 has its own applications running in the background.
Close unnecessary apps by doing the following steps.
Closing or Killing Idle Apps on Samsung Galaxy
For closing running apps
- Unlock your Samsung Galaxy S3 and press and hold the Home button for about 3 seconds, in order to view what apps your Galaxy S3 is running.
- You should now see a list of apps that you have opened on your S3, now to close these apps put your finger on the desired application window and swipe either to the left or to the right.
Here's a video tutorial:
By following these steps, you can close any app that you are not currently using so you can control your battery life. Of course there are other reasons for closing the applications; in some cases, apps stop working properly and they start to freeze and can’t be closed using the Home button. In this scenario, you can force close the application and restart it instead of having to restart the device.
For closing ‘frozen’ apps (which cannot be closed using the Home button)
- Unlock your device and swipe down so you can see the ‘Notification bar’.
- Find ‘Settings’.
- Go to the ‘Applications Manager’. Once there, you will see three tabs:
- Find the application that you want to close. Click on it and select ‘Force Close’.
These methods can be used when applications are running when you don’t want them to, or when you simply need to close down an app you are not using to save battery life of your phone. Either way, doing these can surely help your Samsung Galaxy S3 last longer than it would have been when you do multi-tasking.
