As per screen shot when this is enabled the Bluetooth icon shows as connected as if to a headset. Again every smart watch or fitness band I've ever used doesn't display a constant active connection like this so I'm wondering if it might drain the battery quicker keeping it enabled.
Anyone understand this better than I do I would be grateful for your insight because it's bugging me!

The bluetooth connection and pairing of the Watch without the official app will appear as input or headset.
Regardless of the pairing identified, the consumption remains the same but please bare in mind that any bluetooth connection will increase the normal consumption of the device compared to not having any such connection active.
Hope you find this helpful.
