Unknown data stored on IPhone

Why do I have over 27GB of ‘UNKNOWN’ data being stored on my iPhone? To put it in perspective, I have nearly 6000 photos on here and that doesn’t even use half of that storage amount. 

Ive seen some of the responses to older threads on here, basically avoiding the truth of the really matter.

Keep your iPhone updated to the latest iOS. As of now, it is iOS 14.6 for iPhone 6S and above.


  • Other: Non-removable mobile assets, like Siri voices, fonts, dictionaries, non-removable logs and caches, Spotlight index, and system data, such as Keychain and CloudKit Database. Cached files can't be deleted by the system.
  • System: Space taken by the operating system. This can vary based on your device and model.


About cached files in "Other"

Finder and iTunes categorize cached music, videos, and photos as Other instead of actual songs, videos, or photos. Cached files are created when you stream or view content like music, videos, and photos. When you stream music or video, that content is stored as cached files on your device so you can quickly access it again.


Your device automatically removes cached files and temporary files when your device needs more space.


If storage on your device differs from what you see in Finder or iTunes

Since Finder and iTunes categorize cached files as Other, reported usage for Music or Videos might differ. To view usage on your device, go to Settings > General > [Device] Storage.


If you want to delete the cached files from your device

Your device automatically deletes cached files and temporary files when it needs more space. You don't need to delete them yourself.


In short --> IGNORE, if you are not convinced, Restart the device. You will see that Others Storage will reduce but total storage will remain more or less the same.
