iPhone Storage Full?
Getting "Storage Almost Full" warnings? Can't take photos or install apps? Here are 10 proven ways to free up space on your iPhone - from quick wins to deep cleaning.
First: See What's Using Space
Go to Settings → General → iPhone Storage

Quick Wins (Do These First)
1 Delete Old Messages & Attachments
Messages with photos/videos can use gigabytes of storage:
- Go to Settings → General → iPhone Storage → Messages
- Review large attachments, photos, videos, GIFs
- Swipe left on conversations to delete
- Or auto-delete: Settings → Messages → Keep Messages → 30 Days or 1 Year
2 Clear Safari Cache & Data
Browser cache grows over time:
- Go to Settings → Safari
- Tap Clear History and Website Data
- This removes browsing history, cookies, and cached files
3 Delete Unused Apps
Apps you haven't used in months are just taking space:
- Go to Settings → General → iPhone Storage
- Scroll down to see apps sorted by size
- Tap an app, then Delete App
Tip: Look at "Last Used" date - if it's months ago, delete it.
4 Offload Unused Apps (Keep Data)
Removes app but keeps its data for later:
- Go to Settings → General → iPhone Storage
- Tap an app → Offload App
- Or enable automatic: Settings → App Store → Offload Unused Apps
The app icon stays on your home screen with a cloud icon. Tap to re-download.
Photo & Video Storage
5 Delete Duplicates & Screenshots
- Open Photos app
- Go to Albums → Utilities
- Check Duplicates - merge them to save space
- Check Screenshots - delete old ones you don't need
- Check Screen Recordings - these are HUGE
6 Empty Recently Deleted Album
Deleted photos stay for 30 days, still using space:
- Open Photos → Albums → Recently Deleted
- Tap Select → Delete All
- Confirm to permanently remove
7 Enable iCloud Photos (Optimize Storage)
Keep full-resolution photos in iCloud, smaller versions on phone:
- Go to Settings → Photos
- Enable iCloud Photos

App-Specific Cleaning
8 Clear App Caches
Many apps store lots of cached data:
- Spotify: Settings → Storage → Delete Cache
- Netflix: Delete downloaded shows you've watched
- Podcasts: Delete downloaded episodes
- YouTube: Settings → History & Privacy → Clear Watch History
Nuclear option: Delete and reinstall the app to clear all cache.
9 Manage Offline Content
Downloaded music, movies, and maps take huge space:
- Apple Music: Settings → Music → Downloaded Music → Edit to remove
- Apple TV: Settings → TV → Downloaded Videos
- Apple Maps: Settings → Maps → Offline Maps → delete old maps
- Google Maps: Delete offline areas you no longer need
10 Review "Other" Storage
"Other" or "System Data" can grow large over time:
- Siri voices, fonts, logs, cache
- Hard to clear directly
- Best fix: Back up to computer, then Erase All Content and Settings, then restore
- This "re-packs" storage and typically recovers several GB
Prevent Future Storage Issues
- Enable iCloud Photos with Optimize Storage
- Enable Offload Unused Apps
- Set Messages to auto-delete after 30 days or 1 year
- Regularly delete screenshots and screen recordings
- Stream music/video instead of downloading
Need More Storage?
If you're constantly running out of space, consider upgrading to an iPhone with more storage, or using iCloud+ for photos and files.
