The "Other" category on your iPhone and iPad is basically where all of your caches, settings preferences, saved messages, voice memos, and… well, other data is stored. There is no simple way to identify and remove data in the Other storage category. With a bit of patience, you can reduce the amount of space it takes up on your iPhone or iPad. Follow the steps below to get started.

How to check your iPhone and iPad's storage space using your computer

You can also check your device storage space when your iPhone or iPad is connected to your computer. On Macs running macOS Catalina or later, you'll find this information in Finder. On PCs and Macs running macOS Mojave and older, you'll find it in iTunes.

How to check your iPhone or iPad's storage from your Mac in macOS Catalina

In macOS Catalina, Apple has split up iTunes into three different apps, Podcasts, Music, and TV. That doesn't mean you can't connect your iPhone or iPad to your Mac anymore, though. It just means it's moved.

  1. Connect your iPhone or iPad to your Mac running macOS Catalina.
  2. Open a Finder window.
  3. Click on the device icon in the sidebar under Locations. If you don't see your iPhone listed under Locations, try unplugging your iPhone and plugging it back in.

  1. Open the Settings app.
  2. Tap General.
  3. Tap iPhone [or iPad] Storage.

When you go back to your storage list, you will note that Safari no longer shows any data.

Try deleting old iMessage and Mail data

When you use the Mail app, a cache of all the documents, pictures, and videos you have viewed on your iPhone or iPad are stored on your device. This makes reloading them faster the second time around. But, you don't necessarily want to reopen that kitty GIF that your coworker sent you two years ago. So, you can remove the caches by deleting and reentering your email account information.

Similar to emails, all of the pictures and videos you receive through MMS are stored in the Other category in your storage. You can delete entire conversations, set messages to delete after a certain period of time, or delete individual images and attachments.

As of iOS 11, Apple has made it very easy to clear out these caches automatically. You can enable auto-delete for old iMessages, review large email attachments and remove them from your iPhone or iPad, offload unused apps, and delete music or movies that you've downloaded to your device, but don't actively access anymore.

We've got a detailed guide for freeing up storage by setting your iPhone or iPad to automatically clear caches for emails and iMessages.

How to free up storage space on your iPhone

Try restoring your iPhone or iPad from a backup

One of the biggest culprits of unusually large amounts of Other category taking up space on your iPhone or iPad is a wonky bug in the system. The best way to track down and remove corrupted files is to burn it all down and start over. Don't worry. You can back up your device before you delete everything. That way, you can start fresh without starting over.

Still not fixed?

If you're still getting an Out of Storage error on your iPhone and removing data in the Other category doesn't seem to have done the trick, you can try offloading some additional content from your device.
