It’s a common problem, you’ve been using your iPhone for a while and suddenly it starts running slow. Before you rush to replace it with a newer model, consider clearing your cache. Clearing cache can significantly improve the speed and performance of your device. In this article, we’ll guide you through the process of clearing cache on an iPhone and address some common concerns about the safety and effects of this process.

Clearing Cache on an iPhone

Cache is temporary data that helps your device access information more quickly. Your web browser, for example, stores information about the sites you visit regularly to make loading them faster. However, when the cache becomes too full, it can slow down your device and increase the risk of crashes.

There are several ways to clear cache on an iPhone, depending on the type of cache you want to remove. Clearing cache for third-party apps can be done by either deleting data from each app separately, or by uninstalling and reinstalling the app. To delete data from an app, go to “Settings” and then “General,” then “iPhone Storage.” Here, you will see a list of apps ordered by the amount of space they are using. You can then manually delete data and files from each app or delete them from the “Files” app. Alternatively, you can delete data from iCloud storage.

Here’s how you can clear the cache for Safari and Chrome browsers on an iPhone or iPad:


To clear your history and cookies, go to Settings > Safari, and tap Clear History and Website Data. (Note: Clearing your history, cookies, and browsing data from Safari won’t change your AutoFill information.)

Safari Cache


  1. Open the Chrome app.
  2. Tap the three dots in the upper-right corner to access the Chrome menu.
  3. Tap History > Clear browsing data.
  4. Make sure that there’s a tick mark next to “Cookies, site data” and “Cached images and files“.
  5. Tap Clear browsing data.

Is Clearing Cache Safe?

Yes, clearing cache on your iPhone is safe. The cache is temporary data that does not contain any personal or critical information. The worst that can happen is that you may need to log back into some sites or go through the process of personalizing some settings again.

However, it’s important to note that if you’re using an app that is no longer available for download, deleting the app to clear cache will not allow you to reinstall it. In this case, consider clearing cache for other apps to free up space.

Clearing cache on your iPhone is a simple and effective way to boost its speed and performance. While it may require some inconvenience, such as logging back into sites or personalizing settings again, it is a safe and effective solution to slow performance. To clear cache, you can either use a cleaner app, delete data from each app manually, or delete the app and reinstall it. By regularly clearing cache, you can ensure that your iPhone is always running at its best.
