Streaming your iTunes video purchases on iPhone and iPad should let you save lots of precious storage space on your iPhone or iPad.
However, for a small number of people, iTunes file caching seems to be eating up more space on their devices. This happens when iTunes doesn't properly delete the cached files once you're done streaming a video. This can result in your "Other" storage growing to a tremendous size, and the dreaded "out of storage" message popping up on your iPhone or iPad. This is exactly the issue our reader John is having:
If I stream a movie, it seems to buffer the whole movie, and it never lets it go. I will find that "Videos" is using many, many gigs of storage, even if I have nothing downloaded. How can I fix this?
If you're having the same issue John is, follow along for some tips on how to free up your storage and get Videos working properly again!
Apple has provided fixes for this issue at least twice in the recent past, once with iOS 7.1 and again with iOS 8.1.3. Both those fixes helped some people, and if you haven't updated yet, they could help you as well. If you aren't sure how to check for and install iOS updates on your iPhone or iPad, you can follow our guide:
If you're already on the most current version of iOS and are still having the issue, signing out of iTunes and then signing back in can fix the problem.
Launch the Settings app on your iPhone or iPad.
Tap on iTunes & App Store.
Tap on your Apple ID at the very top.
Tap on Sign Out in the popup menu.
Reboot your iPhone or iPad and sign back in.
Since cached files are associated with your iTunes account, this should flush them. You can verify by going into Settings > General > Usage > About and seeing if your storage has freed up some. If it hasn't, continue on.
Restore your iPhone or iPad
Restoring is always a last result but if none of the steps above have resulted in your video cache being cleared, it may be time to completely restore your device. You can do this with iTunes or iCloud. Just backup and restore, and the cached video files should be gone.
