How to clear the iPad's cache to resolve performance issues
As with most other connected data devices, from PCs to games consoles, to the marvel of modern smartphones (which are basically pocket PCs), iPads use a caching system for data in order to deliver a smoother experience in use.
However, just as with those other devices, caches have a habit of eventually running counter to their intended purpose - that is to say, by caching so much data that they get clogged, they can actually compromise performance rather than improve it.
Thus, with most modern connected devices - including Apple's iPad - it's a good idea to either regularly clear out the cache (much as you'd empty the rubbish or the hoover bag in your home), or if you do find a drop in performance to have that as your go-to first option to try to fix things.
How To Clear Cache On iPad
To start with, you'll want to clear the browsing cache on Safari. To do this, follow these steps:
Swipe down and tap "Safari".
Swipe down and tap "Clear History and Website Data".
Tap to confirm.
Clearing Third Party App Caches
The other type of cache on the iPad is for individual applications and the data they use. Unfortunatley, there's no one-size fits all solution here, as different apps handle caching in different ways.
Some applications have a clear cache option under iOS Settings and then looking at the app preferences for that app.
Others, however, require you to actually into the apps' own setting menu to clear its cache data.
If an app has no options whatsoever, your only real choice is to uninstall then re-install the app.
