The modern iPhone offers plenty of storage for most use cases, but in the golden age of media, you might find your phone’s storage getting filled up quicker than expected. If you’re looking to free up some space without deleting important files and apps, you’re in luck.

The Other storage section of your iPhone often gets filled up with system files and temporary cache data that can take up unnecessarily large amounts of your precious storage space. Frequently cleaning this seemingly mysterious section of your phone is an excellent way to reclaim storage space and improve your phone’s capacity.


This guide will help you learn the best methods to easily clear Other storage on your iPhone and free up space on your mobile device.

What is Other Storage on iPhone?

The “Other” storage section on an iPhone refers to a category of data that doesn’t fall under definite categories like apps, photos, videos, or messages. It encompasses a variety of files and documents that are essential for the proper functioning of your iOS device but may not have specific labels. As a result, “Other” storage can often appear as an unnecessary and confusing portion of your iPhone’s overall storage capacity. However, some of these miscellaneous files are essential for maintaining proper device functionality.

System Data in iPhone Storage settings


Note: After the iOS 15 update, the Other storage has been renamed to “System data“, but it is essentially the same thing. iOS 13/14 and below use the term “Other storage”, while iOS 15/16 and above have been updated to System data.

Here are some of the contents of the Other Storage category:

  • 📂 System Files: These include essential operating system files and components that enable your iPhone to function properly. Whether you’re using an iPhone 11 or an iPhone 14, these files are crucial for the device’s overall performance and can’t be deleted without causing issues.
  • 🗑️ Cache and Temporary files: Applications on your iPhone often generate temporary files, such as cached data, to enhance performance and load times. Over time, these files can accumulate and contribute to the “Other” storage category.
  • 🌐 Safari Browser Cache: The Safari web browser accumulates cache files to load websites faster. The more you use Safari, the more browser cache files get accumulated. Clearing these files can help reclaim storage from the Other section.
  • 💾 App Data: Some apps on your iPhone store data in the “Other” category that isn’t considered part of documents or media. This could include settings, preferences, and other app-related metadata.
  • 🔧 Diagnostic Data: Apple collects diagnostic and usage data to improve its products and services. While this data is typically anonymized, it could contribute to the “Other” storage usage.
  • 🎵 iTunes and Music Data: Whenever you download music from the iTunes Store, TV app, or Music app, it’s indexed and stored as Media. But music streams have caches used to ensure smooth playback, and those are categorized as Other. Files related to iTunes backups and app data syncing are also stored in Other storage.
  • 🗂️ Downloaded Files: Files downloaded from the internet or attachments received via apps like email or messaging platforms can also contribute to the “Other” category. So, if you text or email extensively, getting rid of Other storage on iPhone regularly is important.

As you can see, the Other storage is a catch-all category that stores all kinds of miscellaneous data and can get quite big. In fact, it’s common for this storage category to be as much as several gigabytes in size. Removing these temp files and documents is necessary to optimize your system’s performance and free up precious space. Keep reading to find out the best ways to delete Other storage on iPhone and free up space on your iOS device.

While they serve a purpose, these miscellaneous files keep accumulating and can eventually get very large. If you text a lot with attachments and videos, stream music regularly, or even use Safari extensively, these cached files can quickly add up and cause your iPhone’s Other storage to become huge.

While it differs for each user and specific iPhone model, it’s common for Other storage to be several GB in size.

Is it possible to clear Other storage by resetting my iPhone?

Yes, it’s possible to clear Other storage on the iPhone by resetting the device, but it’s important to understand that this will cause permanent data loss.

When you reset your iPhone to factory settings, it erases all data and settings on the device, including the “Other” storage. This can be an effective way to reclaim storage space that might have been taken up by cached data and temporary files categorized as “Other”. But resetting your phone is a drastic step that should be approached with caution, as it also permanently removes all your apps, photos, messages, and personal data.

You can instead use the steps mentioned in the guide above to easily clear Other storage on your iPhone without risking data loss. If you still want to perform a factory reset, make sure to backup all your iPhone’s data to iCloud as well as a physical backup on external storage media.

Yes, clearing the cache of apps on your iPhone can help free up some space within the “Other” storage category. Cached data are temporary files that apps store for faster loading. While it won’t completely clear Other storage, clearing the cache can reduce its size and improve app performance.


Efficient storage management on your mobile device can help free up space, so you never have to worry about running out at the wrong time. One of the best ways to do this is to remove Other storage on iPhone to get rid of cached files and miscellaneous data.

The Other storage is a catch-all category that comprises cached files and temp data. These temporary files can be removed by clearing Safari cache, clearing mail attachments, deleting app caches, and managing messages and streaming media.

Regular maintenance and app management and the occasional cleaning of caches will help keep your phone’s Other storage in check and ensure you have a smooth user experience on your iPhone.
