iOS 7 introduces the ability to have your apps automatically updated in the background, saving you the trouble of going to the App Store to check for and download updates automatically.
Your device tries to handle this intelligently to avoid draining too much power or consuming data needlessly, but if you don’t want to use this feature at all, you can easily turn it off.
Simply go into Settings, iTunes & App Stores and look for the “Updates” option below automatic downloads.
