Apple released iOS 11 yesterday, bringing with it several new features. The biggest visual change is a revamped Control Center that gives shortcuts and quick controls to certain functions. Some of them include Bluetooth, Wi-Fi and cellular connectivity—but they don’t exactly work as advertised.
According to a new support document, turning off one of these toggles through Control Center doesn’t completely shut down the function. Bluetooth and Wi-Fi will still work for AirPlay, Apple Watch, Location Services, Apple Watch and Continuity features like Handoff and Instant Hotspot.
So pretty much Control Center’s Bluetooth and Wi-Fi toggles only disconnect non-Apple accessories and services, but don’t completely shut off the functions.
iPhone users can still completely turn off Bluetooth and Wi-Fi through the Settings app, but it’s still annoying you can’t do that through the shortcut put in Control Center.
This was probably done in an effort to not mess with the connectivity between Apple services like the Apple Watch or Apple Pencil that solely rely on these connections. Still, it should be up to the users’ discretion if they want these services completely shut off or turned on.
Apple says that Bluetooth and Wi-Fi should be kept on for the best experience on iOS.
