You can speed up your iPhone by clearing its cache — here's how to do it

Apple iPhone 16 held in the hand.

As someone who relies on their iPhone for quite literally everything, I've learned the importance of keeping it running smoothly. Clearing your cache is a simple yet effective way to free up space, improve performance, and resolve minor bugs or slowdowns.

Whether you're troubleshooting an issue or just giving your phone a quick refresh, clearing cached data is a good habit to form. Our iPhones are packed with useful features that simplify everyday tasks. Users can take a screenshot, scan a QR code, or even force restart their device to address issues.

Similarly, clearing the cache for apps like Safari helps optimize performance and ensure your phone runs as efficiently as possible. The process is straightforward and takes only a minute or two. Let’s walk through how to clear the cache on your iPhone step by step.

1. Open settings

Begin by opening the Settings app on your iPhone. This is where you’ll access all the options for managing your device's apps and data.

2. Tap Apps

Scroll down and tap Apps to view a list of all the applications installed on your phone. This is where you can manage all app-specific settings, including data storage and cache.

3. Tap Safari

Find Safari in the list and tap it. Safari stores a significant amount of cached data, including website files and history, which can be cleared to free up space and improve performance.

4. Clear History and Website Data

Scroll down until you find Clear History and Website Data, then tap this option. This will remove your browsing history, cookies, and other cached website data from Safari.

5. Confirm your action

When prompted, tap Clear History to confirm. Your Safari cache will now be cleared, helping to refresh the app and improve its responsiveness.
