iOS 11, the latest operating system from Apple, brings a lot of interesting features, but it also brings some weird ones.
It appears that turning off your Bluetooth and WiFi communications won’t work the same in iOS 11, as in previous versions of iOS. Previously you could turn off the Bluetooth and WiFi connections from the Control Center. But that’s not the case in iOS 11.
Some said it’s a bug, but Apple calls it a feature. From the Control Center, even if the icons turn grey the Bluetooth and WiFi communications won’t be disabled. Your iDevice youl only be disconnected from the networks. To completely turn them off you have to go to Settings.
Apple says that Wi-Fi and Bluetooth will continue to be available even though you tried to turn them off in Control Center in order for you not to lose access to important features (and devices) such as AirDrop, AirPlay, Apple Pencil, Apple Watch, Continuity, Instant Hotspot, and Location Services.
The other weird thing is that even if you turn them off, they will automatically be reactivate the next day, early in the morning a 5 AM, the local time.
It’s a such a bad idea, but it may result more battery drainage, and iPhones have never been great in the battery department. So if you want to save more battery, check in Settings if you Bluetooth and WiFi communications are deactivated.
