Even the powerful iPhones can experience laggy, slow performance sometimes. And Resetting your RAM is one of the ways to fasten up your device. It makes it perform faster and clear out any processing it doesn’t need to currently do. If your phone is feeling sluggish, clearing the RAM should help give it a boost.
Here’s how to do it:
Hold down the power button until you see the slider message “slide to power off”.
Then hold down the home button for about five seconds.
That should do trick 🙂
