When was the last time you cleared the Facebook cache on your iPhone? I'm guessing the answer is never, and that's why you're here. 

You're in the right place, because that cache of yours — the hidden repository of all your in-app activity, from links clicked to pages liked — can slow down your iPhone more than you realize.

Fortunately, clearing your iPhone's Facebook cache is quick and easy. Here's how to do it in two ways.

How to clear the Facebook app's cache on your iPhone

Firstly, you can clear Facebook's browser cache. This will only clear the data that Facebook has stored from websites you visited using the in-app web browser.

1. Launch the Facebook app and tap the three stacked lines in the bottom-right corner.

2. On the next page, tap the words "Settings & Privacy" at the bottom.

3. A drop-down menu will appear with new options. Tap the word "Settings."

4. Scroll down and find the word "Browser" and tap it.

5. Tap the words "Clear Browsing Data."

And that's it, no need to save or confirm or anything, your in-app browser cache is cleared.

However, this still leaves the rest of the data in your Facebook app's cache. To get rid of the rest of this data, you'll need to uninstall or delete the Facebook app and reinstall it from the App Store.

Again, this won't harm any of your account data, photos, or posts. It'll just clear your cache, and require you to log in again.
