iOS doesn’t provide, at the moment, a specific button that you can tap, to shutdown all open apps, declutter the device and free up Random Access Memory. You can only double tap the home button to open App Switcher and manually slide away the applications that you wish to close. However, with the amount of apps used nowadays, it will take some time to stop all of them.
The good news is that I have a fancy little trick for you, that instantly clears up your iPhone’s RAM. This means that, when applied, all apps running in the background will be force closed. What’s even better is that the previously used applications, remain accessible from the App Switcher view. The only difference is that they restart, whenever you return to them. This means that they re-load and prompt you with their home screen view, so that you can start fresh.
Force Clear iPhone Memory
So, when you wish free up your iOS device’s RAM perform this simple trick:
Step 1: From any screen, press & hold the Sleep/Wake button, until the iPhone’s Shutdown screen comes up. (I’m talking about the Power button available at the top of your device, if you’re owning an iPhone 5S or earlier version. The iPhone 6 and later versions have this button re-positioned on the right side).
Step 2: Now, press & hold the Home Button until the iOS home screen is displayed. This signals that the Random Access Memory flush has been completed!
