Restart your iPad after a cold shut down. If that doesn't solve the issue, back-up your iPad through iTunes, reset, then restore the iPad after reinstalling iOS 8.02.
That completely solved issues my dentist client was having on his. There have been a very few iPhones and iPads that required that procedure because something did not correctly overwrite in the initial install.
One other Freeper had a similar complaint and Freepmailed me last week. . . after the back-up, re-install, restore, everything worked great. His battery life was better than before, like mine.
Thanks for the tip. I will do that when I finally get back to my home.
