Facebook, just like any app, has a caching mechanism and is the reason you can see some posts even after you’ve turned off your internet. Cache is great to improve performance but can sometimes become corrupted or overfilled which decreases storage capacity of your device, in which case you would have to clear it, you can do so by following the guide below
Your menu might not look exactly the same but the main goal is to get to “App Manager” and from there the steps should look pretty simular
- Open Your Recents, tap and hold on the logo (or anything else) until you see some options
- Press App Info
- Click On Storage & Cache
- Press “Clear Cache”
Currently, Apple doesn’t allow to clear app cache and says that its “unnecessary to manually clean it” as your phone automatically cleans cache after some time.
What is Cache?
Cache is a storage space where your app keeps certain information for future use. App cache is usually meant to store important elements of certain web pages for future use.
Elements saved in the app cache are usually recurring elements that may appear on several once more throughout surfing. For instance, logos or header images as well as posts and ads
Saving these elements in the cache eliminates the need to download them over the internet every time they are needed again. Hence the app load’s much faster and less bandwidth is consumed.
Apart from the advantage of the speed and reduced bandwidth consumption, caches also have some indirect advantages for the app.
The speed ensures that the overall user experience is fluid and effortless. Internet users generally do not like to wait, and cache allows the app to load all necessary elements in just a few seconds which is way faster then re-downloading the content
