If your iPad seems to be running slowly or otherwise not operating up to par, it could be you don’t have enough storage space left. In order to check to see how much you do have, launch the Settings app from your Home screen and tap on the General tab. When you are in the General tab, choose About and scroll until you see the Available option.
When you have found the Available option in your iPad, you will see how much storage you have left. If it seems as if you are running out, remove some data such as old images, music and videos.
