"Storage Almost Full" is one of the most annoying iPhone notifications. Before you delete your photos or buy more iCloud storage, try these steps — most people recover several gigabytes without losing anything they care about.
Check What's Actually Using Your Space
Go to Settings → General → iPhone Storage. Wait a few seconds for it to load. You'll see a breakdown of exactly what's eating your space. Look for the biggest offenders before doing anything else.
1. Offload Unused Apps
This removes the app but keeps its data. If you reinstall it later, your data comes back.
Settings → General → iPhone Storage → tap any app → Offload App
You can also enable Offload Unused Apps automatically — iOS will offload apps you haven't used in a while.
2. Delete and Re-download Streaming Apps
Apps like Spotify, Netflix, and YouTube cache a huge amount of data. Deleting and reinstalling them clears all that cached content instantly. You won't lose your account or playlists.
3. Clear Your Photo Library the Right Way
Photos are usually the biggest storage hog. A few things to check:
Delete duplicates — iOS 16+ has a built-in Duplicates album in Photos. Open Photos → Albums → scroll down to Duplicates. Merge or delete them.
Check Recently Deleted — Deleted photos sit in a "Recently Deleted" folder for 30 days still taking up space. Go to Photos → Albums → Recently Deleted → Delete All.
Disable iCloud Photo Library syncing and enable Optimize iPhone Storage instead — this keeps full-resolution photos in iCloud and smaller versions on your phone. Settings → Photos → Optimize iPhone Storage.
4. Clear Safari Cache
Safari stores a surprising amount of cached data. Settings → Safari → Clear History and Website Data. This won't log you out of most sites.
5. Check Messages for Large Attachments
Years of photos and videos sent over iMessage add up. Settings → General → iPhone Storage → Messages → Review Large Attachments. You'll see every large file ever sent or received — delete what you don't need.
6. Delete Downloaded Podcasts and Music
If you use Apple Podcasts or Spotify with downloaded episodes, those files pile up fast. In Podcasts, go to Library → Downloaded Episodes and delete old ones. In Spotify, go to Settings → Storage → Delete Cache.
7. Remove Old iMessage Threads
Settings → Messages → Keep Messages → change from Forever to 1 Year or 30 Days. Old conversations and attachments will be automatically deleted.
How Much Space Do You Actually Need?
For most people, 15–20GB of free space is a comfortable buffer. If you're consistently below that, consider:
- iCloud+ storage — $0.99/month for 50GB is genuinely worth it if you have lots of photos
- Upgrading your iPhone — if you have a 64GB model and it's always full, it's a real quality-of-life issue worth solving
Most people recover 3–8GB just by clearing caches and recently deleted photos — start there before spending any money.
