in the past you need to turn on the bluetooth on your iPhone. For Apple watch (series 1 and 2)to be connected, to your phone. Now you don’t even need to turn on your bluetooth... I am missing something is this a new technology or something?
It is a feature of iOS 11. Bluetooth and Wi-Fi now work differently than in previous releases. "Even when toggled off in Control Center on an iPhone, iPad, or iPod touch running iOS 11 and later, Bluetooth and Wi-Fi will continue to be available for AirDrop, AirPlay, Apple Pencil, Apple Watch, Location Services, and Continuity features like Handoff and Instant Hotspot."
Hmm. Turning off Bluetooth in settings on the iPhone, the Watch should have switched over to Wifi, but it didn't. (though the iPhone did lose connection to it when I did so).
Rebooting the Watch did nothing to correct this.
Series 0.
Anyone else seeing this? (that the Wifi radio has been disabled on the watch?)
