There is no single button to clear all cache on an iPhone 13. Instead you clear the browser’s history and website data, offload or reinstall apps that hog space, and restart the phone. That frees storage and fixes most slow or misbehaving apps.
Quick Answer
Open Settings, Apps, Safari and tap Clear History and Website Data. For other apps, go to Settings, General, iPhone Storage, pick an app and tap Offload App or Delete App.
How to Clear Cache on an iPhone 13
- Open Settings, then Apps, then Safari (Settings, Safari on older iOS).
- Tap Clear History and Website Data and confirm.
- Open Settings, General, iPhone Storage to see which apps use the most space.
- Tap a large app and choose Offload App to remove it but keep its documents, then Reinstall App.
- For apps that store a lot of cached data, choose Delete App and reinstall it from the App Store.
- Restart the iPhone to clear temporary system memory.
Cache-Clearing Options
| Method | What it clears |
|---|---|
| Clear History and Website Data | Safari cache, cookies and history |
| Offload App | App binary; keeps documents |
| Delete and reinstall | App and all its cached data |
| In-app clear cache option | Some apps offer their own |
| Restart | Temporary memory |
Troubleshooting
- Clear History is greyed out: Screen Time content limits may block it. Check Settings, Screen Time.
- System Data still large: it shrinks on its own over time and after restarts.
- Signed out of websites: that is expected after clearing cookies.

Frequently Asked Questions

How often should I clear cache?
Only when storage is low or an app misbehaves.
Is there a cache cleaner app?
Third-party cleaners cannot clear other apps’ caches on iPhone and are not needed.
