How To: Stop Force Closing Apps on your iOS Devices – Here's Why
For years, iOS has given users the ability to force close a running app by double-clicking on the Home Button, selecting the app, and then swiping up.

But many iOS users (yes, including me) think that by doing so, that it is freeing up RAM or other resources to make the device run faster. The truth is – IT ISN’T.
However, the iOS app switcher shows all apps that have been opened on an iPhone or iPad, regardless of whether or not they are actually running in the background.
Misconceptions about the iOS app switcher have led many users to adopt the habit of double pressing the home button and swiping up on all apps, constantly, in a futile effort to improve their handset’s battery life or performance.
The truth is, that habit is a waste of time.
For proof, restart your phone, then double-press the home button without launching anything. You’ll see all of the same recent apps in the app switcher, despite the fact that iOS has been completely rebooted and nothing has been opened.
The only time you should force an app to close is if it becomes unresponsive. For example, if you’re using Facebook and the app has crashed, return to the home screen, then double press the home button, then swipe up on the Facebook window to force it to close. Reopening Facebook should return the app to its normal state.
If you’re truly worried about battery life and performance, actual effective ways of improving it include lowering your screen brightness, manually turning on the iOS 9 Low Power Mode, or digging into settings to disable Background App Refresh (under Settings, then General).
