• Step 3. Turn off the switch next to Apple Intelligence.
• Step 4. Confirm that you want to turn it off.

• Step 5. Remove only the apps, downloads, or files you no longer need.

• Step 1. Open Settings > General > iPhone Storage.
• Step 2. Scroll through the app list and choose an app you rarely use.
• Step 3. Tap Offload App.
• Step 4. Tap Offload App again to confirm.

• Step 5. To remove several local copies, tap the three-dot menu, choose Select, select the files, and tap Remove Download.

Method 6: Delete Large Apps, Downloads, and Media

If your iPhone is still nearly full, review which apps and downloaded items use the most space. Deleting an app removes both the app and its related data, while removing offline media keeps the content available for downloading again.

• Step 1. Go to Settings > General > iPhone Storage.
• Step 2. Check the app list, which is generally arranged by storage usage.
• Step 3. Tap a large app to review its app size and stored data.
• Step 4. Choose Delete App when you no longer need the app or its data.

Step 5: Open apps such as Music, Podcasts, TV, or streaming services and remove downloaded songs, episodes, and videos you have already finished.

Step 6: Open Files > Browse > On My iPhone > Downloads and delete unnecessary Safari downloads.

After cleaning your storage, return to Settings > General > iPhone Storage to check how much space you have recovered. Apple Intelligence will continue using space while it remains enabled because its required models are stored on the device.
