How To Get Rid Of Other Storage On iPhone 15: Easy Guide

To clear Other storage on your iPhone 15, check what is using space, clear caches and downloads, delete old messages and large attachments, offload or reinstall apps, and if needed back up and restore the phone. These actions reduce the System Data category that builds up over time. Follow the step-by-step guide below to find and remove the files that make Other storage balloon, and use the tips to prevent it from returning.

Tutorial – How To Get Rid Of Other Storage On iPhone 15

This section will walk you through concrete steps to identify and reduce Other storage, also labeled System Data, so you can free up space and keep your iPhone 15 running smoothly.

Step 1: Check iPhone storage to see how much Other or System Data you have.

Open Settings, tap General, then iPhone Storage to view a breakdown showing how much space Other or System Data is using.

This screen shows a colored bar with categories and a list of apps sorted by size. Look for System Data or Other to gauge the problem and note which apps use the most space so you can target them.

Step 2: Restart your iPhone to clear temporary files.

Power off the iPhone 15, wait a minute, and then turn it back on to let the system clear some temporary caches automatically.

A restart often removes temporary logs and cached files that iOS stores. It is the fastest first step and costs nothing but a minute of time.

Step 3: Clear Safari cache and website data to remove stored browsing files.

Go to Settings, Safari, then Clear History and Website Data to free cache that often sits in Other storage.

Clearing Safari removes cookies, cached images, and site data that accumulate over time. If you use other browsers, open their settings and clear cache there too.

Step 4: Delete old messages and large attachments to free message storage.

Open Messages, swipe left on conversations to delete or tap a contact, go to Info, and remove large photos and videos from the Attachments list.

Messages can hide huge attachments that count toward Other storage. Deleting the full conversation or removing select attachments frees space without touching apps or settings.

Step 5: Offload unused apps to remove app data while keeping the app icon.

In Settings, iPhone Storage, tap an app and choose Offload App to delete the app but keep its documents and data listing for reinstallation.

Offloading reduces app size without losing settings. This is useful for apps you rarely use but still want to keep.

Step 6: Reinstall large apps to clear hidden caches and app data.

Delete and reinstall apps like Spotify, Instagram, or TikTok to remove built-up caches that do not clear with the app alone.

Reinstalling removes the app’s cached files that live in System Data. Back up any app-specific files first if needed, like saved game progress.

Step 7: Remove downloaded media from Music, Podcasts, and Videos to reclaim storage.

Open each media app, find downloaded albums, podcasts, or movies, and remove offline downloads you no longer need.

Streaming content often downloads files for offline access, and these can hide in Other. Removing downloads frees space quickly.

Step 8: Update iOS to the latest version to get system fixes that reduce System Data.

Go to Settings, General, Software Update, and install any available updates to ensure iOS manages storage efficiently.

Apple occasionally improves how the system stores logs and caches. Updating can shrink System Data without any manual cleaning.

Step 9: Back up and restore the iPhone to clear deep System Data buildup.

Use iCloud or a computer to back up your device, then erase all content and settings, and restore from the backup to rebuild storage more cleanly.

A full backup and restore is the most effective way to remove stubborn files in Other, because it forces iOS to reconstruct your data without old cached debris. This process takes time but often yields the largest reduction.

Your iPhone 15 will show less System Data, and you will have more usable storage for apps, photos, and updates. In many cases the biggest wins come from clearing caches, deleting attachments, and reinstalling apps, while a backup and restore handles the toughest cases.

Over the next few days iOS may re-create new temporary files as you use apps. Repeat light maintenance like clearing Safari and removing downloads periodically to keep Other storage in check.

Tips for Getting Rid Of Other Storage On iPhone 15

• Use Settings > General > iPhone Storage to monitor System Data regularly and spot spikes early.
• Enable Messages auto deletion in Settings to remove messages after 30 days or 1 year to avoid attachment buildup.
• Turn on Optimize Photos in Settings > Photos to store smaller versions on the device and full originals in iCloud.
• Offload apps automatically by enabling Offload Unused Apps in the App Store settings to save space without losing app data.
• Before reinstalling or erasing, make a fresh backup, and check that critical app data is safe in iCloud or another service.
• Delete downloaded maps, offline languages, and voice memos that you no longer need, since they can hide in Other.
• Use a computer backup via Finder or iTunes for the most reliable restore when cleaning System Data deeply.

Frequently Asked Questions

What is Other or System Data on iPhone 15?

Other, now often labeled System Data, is a collection of caches, logs, settings, and miscellaneous files that do not fall under apps, photos, or media categories.

These files can include browser caches, system logs, message attachments, and temporary files. iOS manages much of this automatically, but it can still grow over time.

Will deleting messages remove my backups?

Deleting messages reduces local storage and will also change what is stored in new backups, but previous backups remain unless you delete them manually in iCloud or your computer.

If you want to reduce backup size, trim message history before making a fresh backup. Also check iCloud settings to see what gets backed up.

Is it safe to clear Safari data or reinstall apps?

Yes, clearing Safari data removes browsing history and website files, and reinstalling apps removes caches that can be rebuilt when needed.

Make sure you know login credentials for apps you delete, and back up any app-specific files that do not sync to the cloud.

How long does a backup and restore take for iPhone 15?

Time varies based on how much data you have and whether you use iCloud or a computer; small backups may take minutes, large ones can take hours.

Using a wired connection to a computer is usually faster for backup and restore than iCloud, and it avoids network interruptions.

Will updating iOS remove Other storage?

Updating iOS can reduce System Data by changing how caches and logs are stored, but it may not remove large app caches or old attachments on its own.

Updates are a good step, but for stubborn storage you may still need to manually clear caches, delete downloads, or perform a backup and restore.

Conclusion

Clearing Other storage on your iPhone 15 is like cleaning out a junk drawer. Over time, bits and pieces of cache, downloads, message attachments, and system logs pile up and take space you want for photos, apps, and updates. The good news is that most of this clutter is removable with simple steps. Start by checking your storage so you know how big the problem is. Then try quick wins like restarting the phone, clearing Safari, and deleting old messages. If those steps do not shrink System Data enough, offload or reinstall large apps and remove downloaded media. If space is still tight, a full backup and restore rebuilds your iPhone without the old junk.

Treat the process as routine maintenance. Small habits, like setting messages to auto-delete after a month, using Optimize Photos, or turning on automatic offloading, keep Other storage from growing back quickly. And remember to back up before doing anything major. Backups protect your photos and documents and make a restore safe and predictable. If you follow these steps and tips, you will free up space, improve performance, and delay the need to buy more storage or a new device. For readers who want deeper fixes, Apple’s support pages and forums often have device-specific steps, and using a computer backup is the most reliable way to reset System Data. Try these methods today and reclaim the storage on your iPhone 15.
