Can bluetooth ever be faster than wifi?
IOS 11's Control Center doesn't actually disable Wi-Fi or Bluetooth
The shiny new Control Center in iOS 11 isn't working, in fact, you can't turn off Wi-Fi and Bluetooth anymore. You can turn off Wi-Fi and Bluetooth in the Control Center, but the hardware radios will still be running and will come back on fully at 5 a.m. Yeah, that's really weird.
To update: Apple made this clearer in iOS 11.2. If you turn off Wi-Fi or Bluetooth through the Control Center, it will be temporarily turned off. However, the button will change color to indicate that it is only temporarily disabled and a message will appear informing you that it will be automatically re-enabled. You still need to go to the Settings app to permanently turn off Wi-Fi or Bluetooth.
What the control center toggles
CONNECTED:What's new in iOS 11 for iPhone and iPad?
The buttons for WLAN and Bluetooth in the Control Center do not deactivate Wi-Fi and Bluetooth. Instead, the Apple documentation says: “If you toggle the Wi-Fi or Bluetooth buttons in the Control Center in iOS 11 and higher, the connection between your device and Wi-Fi and Bluetooth accessories is immediately disconnected. Both Wi-Fi and Bluetooth will still be available. “Since the hardware radios are active, the battery will of course continue to discharge.
So while it appears that Wi-Fi and Bluetooth are disabled when you flip that switch. According to Apple, this way you can continue to use “important functions” like AirDrop to transfer files, AirPlay to play media on other devices, Apple Pencil, Apple Watch, continuity functions like Handoff and Instant Hotspot, and Location Services.
If you flip the Wi-Fi switch, your device will disconnect from the current Wi-Fi network. However, the WLAN radio remains active. It will only automatically connect to Wi-Fi networks when you move (or drive) to a new location, restart the device, or it is 5:00 a.m. local time. It will also be reactivated if you reactivate WiFi or if you select in the settings that you want to join a WiFi network.
Likewise, if you turn off Bluetooth, the Bluetooth hardware radio will remain active. Your iPhone or iPad will stay connected to Apple Watch or Apple Pencil devices, and features like AirDrop, AirPlay, and Instant Hotspot will still work. However, it gets disconnected from other Bluetooth devices like hardware keyboards and headphones. If you restart your device or change the local time at 5:00 AM, Bluetooth will be fully reactivated. It will also be reactivated when you reactivate Bluetooth or connect to a Bluetooth device through Settings.
In other words, Apple wants things to "just work" so that users can't just turn off Wi-Fi and Bluetooth from the Control Center. This ensures that any failed integration features and hardware devices from Apple like Watch and Pencil will continue to work.
You can see for yourself. If you disable Wi-Fi and Bluetooth using the quick buttons in the Control Center, they will only appear as "Not Connected" and not as "Off" in the Settings app.
How to turn off Wi-Fi and Bluetooth
With Apple, you can completely turn off Wi-Fi and still have Bluetooth - you just have to do it in the Settings app. In other words, in iOS 11, the quick switches in the Control Center are different from the options in the Settings app. Yeah it's weird.
If you turn off Wi-Fi or Bluetooth in Settings, they'll be completely turned off until you turn them back on. The hardware radios will shut down and any functionality that depends on Wi-Fi or Bluetooth (such as location services or Apple Watch connectivity) will no longer work.
To turn off WiFi, go to Settings> WiFi and turn off the WiFi slider.
To turn off Bluetooth, go to Settings> Bluetooth and toggle the Bluetooth slider off.
When Wi-Fi and Bluetooth are disabled in the Settings app, they will show as Off instead of Not Connected on the main Settings screen.
Of course, you can also enable airplane mode. When Airplane Mode is on - something you can do through Control Center - both Bluetooth and WiFi are turned off along with your cellular connection.
This is an odd change, but apparently that's just how iOS works now. If you ever really need to turn off Wi-Fi and Bluetooth, you'll need to go to Settings. If you don't, Apple will assume you aren't serious about the change.
