I've been running with my Polar H7 HRM connected over Bluetooth to my Fenix 6s pro for some time now.
On my last run H7 did not register. Coming home the culprit was a dead battery in the Polar.
Which begs the question. Can I view the battery level of my Polar belt from the watch?
Or, in general, can I view battery state of other Bluetooth connected devices?
Finally, does a widget exist that can show battery levels at a glance?
