Speed up iOS (iPad/iPhone)

I just learned a small trick from the interwebz. It speeds up iOS by cleaning up RAM and processes:

  1. Lock your iPhone or iPad.
  2. Hold the power button until you are told to slide to power off.
  3. Press and hold down the Home-button for 5 seconds.
  4. That’s it! Smile

I tried it and it seems to do the trick. Supposedly this has been possible to do for ages, but I have only done this on iOS 9.x.
