Close Apps That Aren’t Working
Sometimes, the problem isn’t your iPad but rather the specific apps that you’ve installed that could still be running in the background and taking up memory and other resources. If that’s the case, the quickest way to make your iPad go faster again is to close the problematic apps.
Open the App Switcher on your iPad. If you have an iPad with a Home button, double-press it. If you have an iPad without a Home button, swipe up from the bottom to the middle of your screen.
Close the app or apps that are causing issues on your iPad by swiping up to “flick” them off the top of the screen.
If the problem persists, you may want to consider deleting the app and finding a replacement. You can also check the App Store and search for the app to make sure there isn’t a software update you need to install.
Since you’re using the App Switcher, you might as well try closing all apps in there. Usually, apps in the App Switcher won’t affect your iPad, but it might be a good idea to try and see if that fixes the issue.
