What Happened to my Battery?

Liked this game until the latest update, which has killed my battery life on my IPad. Have used the battery section in settings and watched Scrabble percentage of battery usage increase, even over and above Facebook, while the app wasnt even open!! Obviously it is doing something in the background that I can neither see nor stop. Please fix this. For now, I have deleted the app.
