(2025 Updated Guide)

Learn how to clear cache on iPhone in 2025 to boost speed, free up storage, and improve performance. Simple steps for Safari, apps, and system cache.

If your iPhone has started feeling slow or storage seems mysteriously full, learning how to clear cache on iPhone can make a big difference. Clearing cached files removes temporary data that apps and websites store to load faster — but over time, it can take up valuable space and slow performance.

In this 2025 guide, you’ll learn step-by-step how to clear the cache on Safari, apps, and system memory safely without losing important data.

Why You Should Clear Cache on iPhone

Your iPhone stores small data fragments — called cache — every time you browse the web, use social media, or open apps. While this improves speed, too much cached data can cause:

Lag or freezing issues.
Low available storage.
Outdated app behavior.
Browser errors or loading glitches.

Regularly clearing your cache helps your iPhone run smoother, frees up space, and improves privacy by removing stored browsing data.

How to Clear Safari Cache on iPhone

Safari is the default browser for iPhones and one of the biggest cache collectors. Here’s how to clear it:

Open Settings on your iPhone.
Scroll down and tap Safari.
Tap Clear History and Website Data.
Confirm by selecting Clear History and Data.

This action deletes browsing history, cookies, and cached website data. For a more selective cleanup, go to Settings > Safari > Advanced > Website Data and remove individual site caches.

How to Clear App Cache on iPhone (Without Deleting Apps)

Unlike Android, iOS doesn’t have a universal “clear cache” button. However, you can manage storage and app data manually:

Open Settings > General > iPhone Storage.
Wait for the storage data to load — you’ll see which apps use the most space.
Tap an app and check if it offers a “Clear Cache” or “Offload App” option.

Offloading an app removes its app data but keeps personal files like documents or messages. After offloading, tap the app icon again to reinstall it instantly.

Clearing Cache for Specific Apps

Some apps, such as Instagram, TikTok, or YouTube, can build large caches over time. While iOS doesn’t let you clear these caches directly, there are alternatives:

Reinstall the app: Delete and reinstall it from the App Store.
Use in-app tools: Some apps, like Snapchat or Telegram, include built-in cache-clearing features in their settings.
Restart your iPhone: This can clear minor temporary files system-wide.

How to Clear System Cache on iPhone

If your iPhone still feels sluggish after clearing app caches, try resetting system settings (this won’t delete your data):

Go to Settings > General > Transfer or Reset iPhone.
Tap Reset > Reset All Settings.
Enter your passcode if prompted.

This action clears system cache and temporary data but keeps your apps, photos, and files intact.

Extra Tips to Keep Your iPhone Running Smoothly

Restart your iPhone at least once a week.
Keep iOS updated to the latest version.
Use iCloud or Google Drive for backup and free up storage space.
Avoid third-party “cleaner” apps — most are unnecessary and can risk your privacy.

Keep Your iPhone Fast and Organized

Now that you know how to clear cache on iPhone, take a few minutes to perform these steps regularly. It’s the easiest way to improve performance, extend battery life, and ensure apps run efficiently.
