To clear cache on an iPhone, the process depends on whether you want to clear the browser cache (Safari, Chrome, Edge) or app cache.

Clearing Browser Cache

Safari:

1. Open the Settings app.
2. Scroll down and tap Safari.
3. Tap Clear History and Website Data.
4. Confirm by tapping Clear History and Data.

This clears browsing history, cookies, and cached data, and logs you out of websites

. Chrome:

1. Open the Chrome app.
2. Tap the three-dot menu icon (bottom right).
3. Tap History , then Clear browsing data….
4. Select Browsing history , Cookies, site data , and Cached images and files.
5. Tap Clear browsing data and confirm.

This clears Chrome’s cache and cookies but does not close open tabs

. Edge:

1. Open the Edge app.
2. Tap the three-line icon (bottom right).
3. Go to Settings > Privacy and security > Clear browsing data.
4. Select Browsing history , Cookies and other site data , and Cached images and files.
5. Tap Clear now to confirm

Clearing App Cache

iOS does not provide a universal cache clearing feature for apps. To clear app cache:

• Check if the app itself has a cache clearing option in its settings.
• Otherwise, go to Settings > General > iPhone Storage.
• Select the app you want to clear.
• Tap Offload App to remove the app but keep its documents and data, or Delete App to remove the app and all its data including cache.
• Reinstall the app if needed.

Deleting or offloading the app is the most effective way to clear app cache

. In summary, for browser cache, use the Settings app or the browser app itself to clear history and website data. For app cache, either clear it within the app if possible or offload/delete the app via iPhone Storage settings to free up cached data.
