  1. Go to Settings > App and iTunes Stores > Automatic Downloads
  2. Choose which options do you want to be updated or not

It’s okay to let this feature on if you have only an Apple ID connected to one device or one iPhone, but if you have some devices connected to only one Apple ID, the the other devices will also update unnecessary apps.

Besides slowing down your iPhone performance, Automatic Downloads feature also consumes your cellular data.

Simply because it will update all apps without your permission.

So what should you do? You have to update apps manually or update them using Wi-Fi only and disable the Use Cellular Data in Settings > iTunes & App Store.
