@v.sacre The reason is that, after first activity with BT sensors connected, increased battery drain can happen after finishing the activiy. My “workaround” is to soft reset the V1 after every activity… This bahavior keeps the battery drain in a “stable” drain.
I can test the “zombie BT process” powering on my Coospo HR armband, V1 vibrates as if it was connected to the sensor.
And this doesn’t seem to be happening in my Race S.
