An unusual hack which can dramatically increase the available storage space on your iPhone has been discovered.
The trick is capable of freeing up lots of space on your phone, which would be great if you’re using a lower-capacity device.
Here’s the trick. Go to Settings>General>About, and scroll down to ‘Available’.
Check how much storage you have left, and then head to the iTunes Store.
Search for a movie which is bigger than the space available on your phone. Something like The Lord of the Rings: The Two Towers (which is about 6.84GB) should do the trick.
Now click ‘Rent’ at the top of the page. Don’t worry — if you don’t have room, you won’t be charged, and an error box saying you don’t have enough available storage will appear.
After you’ve clicked ‘OK’, head back to settings and check your available storage again. It should have increased, potentially quite significantly.
This trick appears to force the phone to have a cache cleanout, freeing up a lot of space in one go.
The trick was discussed on Reddit’s iPhone forum, where some users with higher-capacity phones said they had gained up to 4GB of space in just a few tries.
