What you can notice from your phone performance after long time usage, it become slower and delay in responding. It is a common scenario where I believe everyone will experience it but as for today, I may share some tips with you to improve the phone performance. Before we start, let’s have a brief explanation on how the app actually running in your device. After you completed a task with an app, you will definitely “turn off” the app by using the “back” or “home” buttons on your device. This action is actually not killing the app which it is continue running at the background. Some of you may install some App Killer to kill these apps, but the fact is that this App Killer just killing the app from your eyesight, not at the background.
To know how many apps are actually running in your device (SGS3), simply go to Settings –> Application Managers. Navigate to the Running tab and you can see how many apps running in your device. Try to identify the apps that you really want to kill as you may find out some app likes Google services just cannot be killed. These app are some of the system app which keep your device running, the concept is the same as system service in computer. You can refer to the picture below for better understanding.
