Since iOS 7, your iPhone automatically updates all your apps, which is a wonderful thing … until it stops. Not only does this feature drain the battery faster when it's activated, it also lets you make changes to features, settings, and user interfaces in the apps you already know and love. For this reason, you can easily disable the feature and prevent apps from being updated automatically.
Overall, automatic app updates are a good thing . However, manually updating your apps is not a crazy thing. To disable automatic app updates, open the Settings app, go to iTunes & App Store, and disable App Updates at Automatic downloads . That was it's.
Your applications no longer automatically download in the background. Instead, a notification badge is displayed in the App Store app each time an update is published. You will need to go to the App Store and either install all updates at the same time or one after the other.
