Apple, with its iOS 11 brought many changes to its mobile OS, and one of the significant one is the all new Control Center. The new Control Center is a lot more fully featured, with a customizable layout and a number of new added controls accessible with Force Touch. But one aspect of it is now proving to be a bit of a usability problem: the Bluetooth and Wi-Fi controls.
Reported by Motherboard first, in iOS 11, Apple lets you disconnect devices or networks by toggling off Wi-Fi and Bluetooth button within the Control Center, but that, however, does not deactivate the actual radios in the device. This is a significant change from how these buttons have worked in the past.
However, this behavior is exactly what Apple wants and also mentions in its own documentation. The company says, “In iOS 11 and later, when you toggle the Wi-Fi or Bluetooth buttons in Control Center, your device will immediately disconnect from Wi-Fi and Bluetooth accessories. Both Wi-Fi and Bluetooth will continue to be available.”
The reason for the said behavior is because Apple wants the iPhone to be able to continue using AirDrop, AirPlay, Apple Pencil, Apple Watch, Location Services, and other features.
Security researcher Andrea Barisani, told Motherboard that it’s “good practice” to disconnect from Bluetooth and Wi-Fi if you’re concerned about potential attacks. And to do that in iOS 11, you must go directly into each respective settings menu and switch the button off.
