Storage

Hi BigFray,

We understand you'd like to remove storage occupied by 'other'.

As stated in this article: How to check the storage on your iPhone, iPad, and iPod touch,

'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.'

In order to remove 'other', we would recommend ensuring you have a backup of your data (How to back up your iPhone, iPad, and iPod touch), then Restore your iPhone. You can learn how to do so here: Restore your iPhone, iPad, or iPod to factory settings.

Once complete, Setup As a New Device (do not restore your backup).

If the issue is resolved, go ahead and restore your backup. You can learn how to do so here: Restore your iPhone, iPad, or iPod touch from a backup.

If the issue recurs once your backup is restored, there may be an issue with your user data, in which case we would recommend you sync your content to a service such as iCloud, then erase your device and Setup As a New Device - all synced data will return, though you will need to re-download your apps and adjust your user settings to your preference.

Hope this helps!

Thank you for using Apple Support Communities.

Cheers!
