Latest iOS 11.2 beta clarifies that Control Center doesn't fully disable Wi-Fi and Bluetoo...
A somewhat controversial change in iOS 11 will come with a little more clarity in the forthcoming iOS 11.2 update, with the latest beta adding a prompt informing users that turning off Wi-Fi and Bluetooth via Control Center doesn't fully disable them.

Apple made the switch with the launch of iOS 11 in September, ensuring that features such as AirDrop and Apple Watch connectivity remain active even if a user disables wireless connectivity. Rather than turning off the wireless functions completely, flipping the switches in Control Center simply disconnect from networks and third-party accessories.
With the release of iOS 11.2 beta 3 on Monday, Apple has made a small but noteworthy change to help communicate how Control Center works. Upon installing the update, users who disable Wi-Fi or Bluetooth via Control Center are met with a prompt. For Wi-Fi, it reads:
"Disconnecting Nearby Wi-Fi Until Tomorrow. The current Wi-Fi network and others nearby will be disconnected until tomorrow. Wi-Fi will continue to be available for AirDrop, Personal Hotspot, and location accuracy."

And when Bluetooth is toggled in Control Center, iOS 11.2 states:
"Disconnecting Bluetooth Accessories Until Tomorrow. Currently Connected accessories will be disconnected and other accessories will not connect. Bluetooth will continue to be available for Apple Watch, Apple Pencil, Personal Hotspot, and Handoff."
Because iOS 11.2 remains in beta, things could change before the software is released to the public. But as of beta 3, toggling Wi-Fi and Bluetooth in Control Center changes their icons from blue (active) to white (inactive).
To completely turn off either Bluetooth or Wi-Fi, users must delve into the Settings app in iOS, or enable Airplane Mode in Control Center or via Settings.

My work-around to this is to tell the phone to "forget" all WiFi networks I may have used in the past and use my cell plan data anyplace outside of home, work or family members' homes. That way my phone is not constantly connecting to crappy networks. Face it, most public WiFi is not only inherently unsecured, it is ridiculously slow.
If Cook really cared about it’s user base, he’d put in an option to allow me to change this from default disconnect to off. It can default to disconnect, sure, but making me go into settings and turn off WiFi and Bluetooth every time I want to airdrop and worse WiFi every time I leave my house— it’s ludicrous.
Experts toggle "don't tell me again" the 1st time.
People like me might say OK for about 5 to 10 times until we "get it."
Some might be grateful for the reminder every time.
Everybody wins?
liftfromtheknees said: It's all about trying to provide a better user experience. The vast majority of people want good location services (GPS positioning) and are perfectly willing to have WiFi used for that purpose. Apple has apparently learned that people are turning off WiFi as a way to disconnect from their WiFi internet connection, but then are frustrated by their location being less accurate. The control center option meet their (common) needs. Likewise, if you have an Apple Watch or an Apple Pencil, you almost certainly want those devices to stay connected via BT even if you want to disconnect from some speakers. The message Apple intends to present will explain things nicely and most people will be able to ignore it without harm.
My suggestion to you is to review your location services and WiFi preferences rather than using a heavy-handed turn everything off approach when you leave the house. Personally, I trust that Apple is complying with my settings to not allow (for example) the Walmart or Starbucks apps to use my location services and I don't allow my phone to automatically connect to random WiFi hot spots. Therefore I feel perfectly secure leaving WiFi and BT on.
It certainly can't help while driving as one would pass through WiFi networks too quickly to be of any use.
Still they should 3D touch it to disable completely or a triple toggle: On/disconnect/Off.
still, if a function needs a pop up to explain what it is doing it isn’t very intuitive.
“Im sorry dave i can’t do that for you”
I just hope we don't get the confirm dialog mentioned in this article every time we hit the button. Showing it only once, or better yet including a "Don't show this again" option, would be my preference.
The icons say it all. Crossed "Icons" is "off", white icons mean "disconnect".
It might be improved with a different shade for the icons for "disconnect".
