How to clear Facebook cache on your iPhone

Let’s examine several different methods for clearing the Facebook cache on an iPhone. Doing this periodically should help the app run more quickly and efficiently.

What is Facebook cache on iPhone?

Whenever you use Facebook, the app cache stores your frequently used information as cache data to reduce loading times and data usage. These cache files are stored in a dedicated location on your iPhone.

If you leave the cache alone, it could quickly gobble up storage (depending on how much you use Facebook), and if you have outdated or corrupt cache files, Facebook will slow down significantly. If Facebook is acting up, underperforming, or freezing, it’s time to empty the cache.

Clearing Facebook’s cache isn't always necessary. If the app is working fine and you have plenty of storage, leave it alone, but if it’s affecting performance, follow these steps to clear the app’s cache.
