Closing the Apps on Your iPhone
The iPhone is a power-packed intelligent device which has amazing applications which have the capacity
to run simultaneously (without compromising on the processing speed). However, the trick comes when you have to close one or more of the currently running tasks (like applications) on your iPhone. In this case, the Multi-tasking status bar comes to your rescue, as you can manage the ongoing applications on your iPhone. This is similar to managing the simultaneously running programs on your desktop computer.
Double clicking (or tapping) on the ‘Home’ button will pull up the Multi tasking status bar at the bottom of the screen on your iPhone. In case there are many apps open at a time, you might have to swipe left or right to locate the app you want to deal with. Bring up the application and click on the ‘-’ button at the top left corner. This will close the application.
