Clearing your iPad's cache is a good tool if your iPad is acting strangely, or you're running out of storage space.
Like any computer, your iPad keeps some memory space reserved to store information you've recently used, like internet cookies and images. This space is called a cache. Ideally, the cache speeds up your iPad by giving the device fast access to certain data if you need it again.
But if you notice that your iPad has been sluggish recently, or is misbehaving in some way, one remedy may be to clear the cache. If that doesn't work, you might try some other troubleshooting tips found in our article "Can iPads get viruses?"
There are two caches you can try to clear: the one used by your web browser, Safari, and the cache for your apps. To delete an app's cache, though, you need to delete the app. However, you can then reinstall the app immediately after.
3. Confirm that you want to do this by tapping Clear in the Clear History and Data dialog box.
After a moment, your browser cache will clear. This will reclaim space used by the cache and delete web information that your iPad is temporarily storing. Note that it'll also sign you out of any web pages you are logged into, so it'll be like you are browsing on a new device.
1. Open the Settings app.
2. Tap "General," and then tap "iPad Storage." The iPad Storage page will show you how much space is used on your iPad by different kinds of apps. (It might take a minute or two for this to appear, since the iPad has to calculate the free and used space.)
3. Your iPad might make recommendations to save space, such as deleting apps you rarely use or deleting videos or email attachments. If you want to save space, you can try one or more of these options.
4. Review the apps installed on your iPad - they are arranged from the largest at the top to the smallest at the bottom.
5. Tap an app that you want to clear. Note that the app's details page shows you how much space the app takes, as well as how much space its data is consuming.
