While it may seem that you can turn off Bluetooth and Wi-Fi in the iOS 11 control center simply by toggling the feature off, that’s not exactly the case.
If you open up the Control Center and toggle off Wi-Fi, what actually happens? You’re disconnected from your current network and your phone doesn’t search for new networks. If you toggle off Bluetooth, you’re disconnected from connected devices and your phone stops searching for new devices.
But Bluetooth and Wi-Fi on your phone actually remain turned on, meaning that they will continue to draw on your iPhone’s battery. It also means that certain features like AirDrop, Continuity features including Handoff and Instant Hotspot, AirPlay, and location services will remain active. Your iOS device will also remain connected to your Apple Watch or Pencil.
Aside from draining your battery, this intentional Apple feature opens users to Wi-Fi or Bluetooth security risks that you think may not be applicable because your features are “off.”
How to Really Turn Bluetooth and Wi-Fi Off
To really turn these features off, you’ll have to go to Settings > WiFi and Settings > Bluetooth.
