The good news is that we 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
