"Quick switch simply disconnects phone from access points and devices rather than turning off the radios, in move criticised by security researchers."
"On iOS 11, pressing the wifi toggle immediately disconnects the iPhone or iPad from any wifi networks, but leaves the wireless radio available for use by location services, scanning for the names of nearby wifi access points. The Bluetooth toggle operates in a similar fashion."
"To actually turn off Bluetooth and wifi users will need to head into the Settings app and manually turn them off, which deactivates them until 5am the next morning"
"But security researchers warn that having either wifi or Bluetooth active when not in use puts users at risk of attack, calling the change “stupid” and “not clear for the user”. Only recently researchers demonstrated that, due to a weakness in the implementation of Bluetooth in some smartphones and tablets, hackers could wirelessly hijack a device without the user having to accept a connection or download anything."

Let’s be clear. Leaving WiFi or Bluetooth active puts users at risk of attack in the same way that leaving your house to go anywhere puts you at risk of getting in a traffic accident.
