iOS 11 may have a brand new Control Centre that is much more useful than before, but it looks like there’s a slight problem with it – it doesn’t let you fully turn off your Wi-Fi and Bluetooth connectivity. According to reports, toggling off your Wi-Fi and Bluetooth on the Control Centre does not deactivate the actual radios in the device.
According to a report from Motherboard, if you turn off your Wi-Fi or Bluetooth via the new Control Centre, they still remain somewhat active. Apple leaves then running in the background to perform other Apple related tasks.
According to Apple,
“In iOS 11 and later, when you toggle the Wi-Fi or Bluetooth buttons in Control Centre, your device will immediately disconnect from Wi-Fi and Bluetooth accessories. Both Wi-Fi and Bluetooth will continue to be available, so you can use these important features:
Continuity features, like Handoff and Instant Hotspot
This sounds useful from Apple’s point of view, giving you a seamless experience on iOS 11. However, if you are concerned with your security, it is always best to turn off Wi-Fi and Bluetooth completely when not in use. You still can do that of course, but you have to head on to the Settings app to turn them off manually.
