Like any computer, your iPad uses a reserved memory space, called a cache, to store information that you have recently used.
Ideally, it speeds up your iPad by allowing the device to access it quickly if you need it again. However, if you notice that your iPad has recently been slow or is behaving badly, you can clear the cache. If that does not work, you can try other troubleshooting tips found in our article "Can iPads be infected with viruses?"
You can try to clear two caches: the one used by your web browser, Safari, and the cache of your applications. To remove the cache of an application, however, you must remove the application, but you can then reinstall it.
Erase your Safari cache on an iPad
1. Open the Settings application, then press "Safari".
2 Tap "Clear history and data from the website".
3 Confirm your intention by pressing Clear in the Clear History and Data dialog box.
After a while, your browser's cache will erase. This will recover the space used by the cache and remove the web information that your iPad temporarily stores. Note that this will also disconnect you from all the web pages to which you are connected, so it will be like surfing a new device.
Clear your app's cache on an iPad
1. Open the Settings application.
2 Tap "General" and then "iPad Storage". The Storage page on iPad will show you how much space is used on your iPad by different types of applications. (It may take a minute or two for this to appear because the iPad needs to calculate the free and used space.)
3 Your iPad can make recommendations to save space, such as deleting applications that you rarely use or delete videos or attachments. If you want to save space, you can try one or more of these options.
4 Review the applications installed on your iPad – they are organized from the largest to the smallest to the smallest.
5 Tap an application you want to erase. Note that the application details page shows you the amount of space used by the application, as well as the amount of space used by its data.
At this point you have several options:
- Tap "Remove application" to uninstall the application (and delete all data cached by the application). Then go to the App Store and reinstall the application. You will get a new version of the application without stored data. You can do it even for a paid application without paying a second time. This is a good option if the application itself is relatively small but the data takes up a lot of space.
- Tap "Unload application" to uninstall the application while keeping the app's data on the iPad. This may be a good idea if the application itself is very large and you need to recover some space, but you may want to reinstall it later and continue to use the existing data.
- The Photos application is an exception. iOS will not let you uninstall it, but you can press "Enable" to allow the app to save smaller photos, which will potentially save you a lot of space.
