"Storage Almost Full" is one of the most common iPhone warnings. It can stop you from taking photos, installing updates, or downloading apps. The good news is you can usually reclaim several gigabytes without losing anything you care about. Here's how to do it, step by step.
Step 1: See what's taking up space
- Open Settings > General > iPhone Storage.
- Wait a moment for the colored bar to load. It shows how much space apps, photos, media, messages, and system data use.
- Scroll down to see apps sorted by size.
Your iPhone may also show Recommendations at the top, such as "Offload Unused Apps" or "Review Large Attachments." These are a great place to start.
Step 2: Offload apps you rarely use
Offloading removes an app but keeps its documents and data. The icon stays on your Home Screen with a small cloud symbol, and tapping it reinstalls the app with your data intact.
- In iPhone Storage, tap an app you rarely use.
- Tap Offload App.
To have your iPhone do this automatically, go to Settings > App Store and turn on Offload Unused Apps.
If you never use an app, tap Delete App instead to remove it and its data completely.
Step 3: Clean up Messages
Years of photos, videos, and GIFs in text threads can quietly take up gigabytes.
- Go to Settings > Messages.
- Under Message History, tap Keep Messages and choose 1 Year or 30 Days. Warning: this permanently deletes older messages and their attachments, so only do it if you're comfortable losing them (or if they're backed up in iCloud Messages).
- To be more selective, go to Settings > General > iPhone Storage > Messages and tap Review Large Attachments. Swipe left on items to delete them.
Step 4: Manage your photos and videos
Photos and videos are usually the biggest space users. You don't have to delete them to save space.
Use iCloud Photos with Optimize Storage
- Go to Settings, tap your name, then iCloud > Photos.
- Turn on Sync this iPhone (called iCloud Photos on some versions).
- Select Optimize iPhone Storage.
Your full-resolution photos are stored in iCloud, and your iPhone keeps smaller versions, downloading the full ones when you need them. Note that you may need to buy more iCloud storage if your library is larger than the free 5 GB.
Empty Recently Deleted
Deleted photos stay in a Recently Deleted album for about 30 days.
- Open Photos and scroll to Utilities > Recently Deleted.
- Unlock with Face ID or your passcode.
- Tap Select > Delete All.
Remove duplicates
- In Photos, scroll to Utilities > Duplicates.
- Tap Merge to combine duplicate photos and keep the best quality version.
Clean up videos
Long videos, especially in 4K, take up a lot of space. Review your Videos media type in Photos and delete the ones you don't need. You can also lower future video quality in Settings > Camera > Record Video.
Step 5: Clear Safari website data
- Go to Settings > Apps > Safari (on older iOS versions, Settings > Safari).
- Tap Clear History and Website Data.
This signs you out of websites and clears history, so do it only if that's okay with you. For a gentler option, go to Advanced > Website Data and remove data for individual sites.
Step 6: Delete downloaded music, podcasts, and videos
Offline downloads add up quickly.
- Music: Go to Settings > General > iPhone Storage > Music, then swipe left on artists or albums to delete downloads.
- Podcasts: In the Podcasts app settings, limit how many episodes are kept downloaded.
- Streaming apps: Apps like Netflix or Prime Video store downloads inside the app. Open each and delete finished shows.
Step 7: Clear app caches
Some apps, like social media and chat apps, store large caches. In iPhone Storage, look at the Documents & Data size for each app. Many apps offer a "Clear Cache" option in their own settings. If not, deleting and reinstalling the app clears its cache (make sure you know your login first).
Step 8: Check "System Data"
System Data (sometimes shown as "Other") includes caches, logs, and temporary files. It changes on its own and you can't delete it directly. Restarting your iPhone and keeping iOS updated can help it shrink over time.
Step 9: Move files off your phone
If you're out of options, move files somewhere else:
- Back up photos to a computer or another cloud service, then delete them from the phone.
- Use the Files app to move documents to iCloud Drive.
- Use a USB-C or Lightning flash drive designed for iPhone to store photos and videos.
How much free space should you keep?
There's no hard rule, but keeping a few gigabytes free helps your iPhone run smoothly and leaves room for iOS updates, which often need extra space to install.
Quick checklist
- Check iPhone Storage and follow recommendations
- Offload or delete unused apps
- Shorten Message history or remove large attachments
- Turn on Optimize iPhone Storage
- Empty Recently Deleted and merge duplicates
- Clear Safari data and offline downloads
Do this every few months and you'll rarely see that "Storage Almost Full" warning again.
