It’s frustrating when your iPhone shows “Storage Almost Full” even after you’ve deleted photos, videos, or apps. This issue prevents you from installing updates, downloading new apps, or even taking photos.
The good news is that in most cases, this is not a hardware problem but a result of hidden files, cached data, or system glitches. In this guide, we’ll explain why storage can remain full and provide step-by-step fixes to reclaim space on your iPhone.
Why iPhone Storage Shows Full After Deleting Files
Understanding the causes helps in troubleshooting:
-
Recently Deleted Files: Photos and videos remain in the “Recently Deleted” album for 30 days.
-
App Caches: Apps like Safari, Instagram, and Messages store temporary data that doesn’t delete automatically.
-
System Storage (Other): iOS caches, logs, and updates occupy space labeled as “System” or “Other.”
-
Messages and Attachments: Large message attachments or old conversations can take up significant space.
-
iCloud and Sync Issues: Sometimes storage updates don’t reflect properly due to syncing delays.
-
Hidden Downloads or Offline Content: Offline music, podcasts, or videos may still occupy space.
Now let’s go through reliable fixes.
1. Empty the Recently Deleted Album
Deleting photos or videos doesn’t free space immediately—they remain in Recently Deleted for 30 days.
Steps:
-
Open Photos → Albums → Recently Deleted
-
Tap Select → Delete All
This immediately frees up storage taken by deleted media.
2. Clear Safari Cache
Safari and other browsers store cached files that can occupy gigabytes over time.
Steps:
-
Settings → Safari → Clear History and Website Data
-
Confirm deletion
This frees up storage and may improve browser performance.
3. Delete App Cache and Data
Some apps accumulate temporary files over time.
Steps:
-
Settings → General → iPhone Storage
-
Tap an app → Check Documents & Data
-
If cache is large, Delete App → Reinstall
Popular offenders include social media apps, messaging apps, and streaming services.
4. Review Large Message Attachments
Messages with photos, videos, or GIFs can take up space silently.
Steps:
-
Settings → General → iPhone Storage → Messages
-
Review Photos, Videos, GIFs & Stickers
-
Delete large attachments or old conversations
This is especially useful if you frequently send media via iMessage.
5. Offload Unused Apps
iOS allows you to remove apps without deleting their data. This frees storage while keeping your settings intact.
Steps:
-
Settings → General → iPhone Storage → Enable Offload Unused Apps
-
Or manually offload large apps
Offloading is ideal for apps you rarely use.
6. Check System Storage (Other)
iOS categorizes caches, logs, updates, and temporary files as System or Other.
Fix:
-
Restart your iPhone to let iOS clear temporary files
-
If “Other” storage remains high, perform Settings → General → Reset → Reset All Settings (does not delete personal data)
This clears system cache while preserving apps and media.
7. Delete Old iOS Updates
iOS downloads updates automatically, which can take up significant space.
Steps:
-
Settings → General → iPhone Storage → iOS Update
-
Delete old downloaded updates if available
-
Reinstall only if needed
This can free several gigabytes instantly.
8. Manage Offline Media
Offline music, podcasts, and videos often consume unexpected space.
Steps:
-
Check apps like Spotify, Apple Music, Netflix, YouTube for offline downloads
-
Delete unnecessary offline content
Streaming content instead of keeping offline copies saves storage.
9. Enable iCloud Photos
Moving photos to iCloud can free local storage without losing images.
Steps:
-
Settings → Photos → iCloud Photos → Optimize iPhone Storage
-
High-resolution images are stored in iCloud; smaller versions remain on the device
This balances storage and accessibility.
10. Restart Your iPhone
Sometimes, storage updates don’t reflect immediately. A simple restart can refresh the system and reclaim space.
Steps:
-
Press and hold the Power button + Volume Up/Down
-
Slide to power off → Turn back on
Storage should update correctly after a restart.
11. Factory Reset (Last Resort)
If your iPhone still shows full storage after all fixes, a factory reset can reclaim space by removing corrupted system files and cache.
Important:
-
Backup all data to iCloud or iTunes
-
Settings → General → Reset → Erase All Content and Settings
-
Restore essential apps only
This provides a clean slate and resolves hidden storage issues.
