This, that and the other
My wife and myself each have an iPhone 4S, which we have synchronised with our Mac Pro using iTunes. When I view the storage used, the ‘other’ category show as approximately 7-9GB of the 32GB available. What is this? Barry Kendal
Other is usually storage claimed by apps that can’t be neatly categorised into photos, video, music and so on. Cached WhatsApp chats, for example, or saved games. Check usage in Settings > General > Storage & iCloud Usage > Manage Storage. Some apps have an option to discard this, but mostly they need to be deleted and reinstalled.
Sometimes apps can have bugs whereby they fail to free up temporary space they’ve been allocated. If the size of ‘other’ seems to creep up inexorably, even though you’re not saving anything, this may be the cause. Until fixed, you may need to reinstall that app periodically.
The final source of ‘other’ storage is when an iTunes sync gets corrupted and creates dupes of an app’s storage. Then, a backup and restore is needed to get rid of it.
If your iOS device shows too much storage in the ‘Other’ category, check your video collection.
