How To Deactivate Wi-Fi And Bluetooth On Your iPhone
You disconnected the Wi-Fi and the Bluetooth connection on your iPhone and wonder why AirDrop and AirPlay still work? With iOS 11 Apple changed the function of the Wi-Fi and Bluetooth icons in the control center. They do no longer deactivate the complete function but only the current connection. We show you how to deactivate the connection completely.
To deactivate Bluetooth or Wi-Fi open your settings app and click on the respective buttons. As soon as you turn the switch all connections are disconnected.
You can recognize all deactivated functions by their appearance in the settings app: they are crossed out with a grey background. If this is not the case they are still active.
As of now, there is no other way to completely deactivate Wi-Fi or Bluetooth outside of the settings app.
