The main controls for Bluetooth and Wi-Fi on Apple’s newly launched iOS 11 software cannot actually be used to turn those features off.
Users of Apple’s redesigned control centre, the quick screen for changing settings and controls found by swiping up from the bottom of the screen, have found the toggles for Bluetooth and Wi-Fi don’t actually deactivate them.
Instead, these features disconnect users from current Bluetooth or Wi-Fi pairings and networks, but leave the features active.
To actually disable Wi-Fi or Bluetooth, iPhone users must go into settings and turn both off completely.
Apple said the reason it keeps Bluetooth and Wi-Fi enabled is to keep users connected to “important features”, such as connecting to AirPlay, Apple Watch and to use features such as AirDrop and location services. Deselecting Bluetooth and Wi-Fi in the Control Centre will only disconnect from third party accessories like headphones, or from Wi-Fi networks.
iOS 11 will automatically try and reconnect to known devices using Bluetooth and Wi-Fi at 5am every morning if they have only been toggled off in the control centre.PSA: iOS 11 new control center WiFi and Bluetooth toggles don’t actually turn off their respective radios.
Leaving on Bluetooth and Wi-Fi is not considered a major drain on battery life, but does raise some security concerns. Last week, security researchers discovered a series of vulnerabilities that could be used by hackers to take over mobile phones using Bluetooth.
But the feature has concerned users largely due to its lack of clarity, even after Apple had redesigned the iPhone and iPad control centre as part of its software update in an attempt to make it more intuitive.
iOS 11, released on Tuesday, has also created issues for Microsoft email users, blocking people with Outlook addresses from sending email using its Mail app, while Snapchat has issued a patch to inform users if people have been recording their video messages.
