Since iOS 11, turning Bluetooth off from the control center only puts Bluetooth on a timeout until the next morning instead of disabling it permanently, as one would expect. Even when it’s off, the antenna stays on, looking for new devices. You can turn it all the way off by digging into the settings menu, but as soon as you turn it on for any reason, the cycle starts again.

I personally really like this, because 95% of the time when I turn off my Bluetooth what I’m really wanting to do is put it on pause. The times when I want to turn it off completely, I also want to turn off everything else (Wi-Fi etc.) so airplane mode (which does not time out) works great.
