Yes but does it matter if your BT is turned off _visually_? The device can still send data. Besides, receiving consumes more power than sending, theoretically

Yes but does it matter if your BT is turned off _visually_? The device can still send data. Besides, receiving consumes more power than sending, theoretically Apple can just shut off the receiving part and send intermittently (every 2 sec or so) and achieve very minimal power usage. Again, this is just speculation, I’m genuinely interested in the details.
