Got a sluggish iPhone? Here's a quick tip to fix it.

According to tech expert website Gizmodo, the fastest and quickest way to fix a slow processing iPhone is to empty out the device's RAM.

To do this press and hold the Power button until the 'slide to power off' option appears. On this screen again press and hold down the Home button - the screen will flicker and take you back to your home screen. It's as simple as that.

The good news: It also works on other iOS devices like the iPad and iPod Touch.
