Turning Off Wi-Fi and Bluetooth in iOS 11's Control Center Doesn't Actually Turn Off Wi-Fi or Bluetooth (vice.com)
An anonymous reader shares a Motherboard report: Turning off Bluetooth and Wi-Fi when you're not using them on your smartphone has long been standard, common sense, advice. Unfortunately, with the iPhone's new operating system iOS 11 - which was released to the general public yesterday - turning them off is not as easy as it used to be. Now, when you toggle Bluetooth and Wi-Fi off from the iPhone's Control Center -- the somewhat confusing menu that appears when you swipe up from the bottom of the phone -- it actually doesn't completely turn them off. While that might sound like a bug, that's actually what Apple intended in the new operating system. But security researchers warn that users might not realize this and, as a consequence, could leave Bluetooth and Wi-Fi on without noticing. Numerous Slashdot readers have complained about this "feature" this week.
One of the Bluetooth vulnerabilities cited as a motivation for turning BT off actually was fixed in every release subsequent to 9.3.5.
But, I mean, you do you -- if you really think having to go to Settings to power off the radio is so bad that you are willing to forego this (and many other) security fix(es), go for it. We won't feel bad if you get pwned by a long-since-patched bug though.
