is it normal that the hr sensor always blink? even when the watch is taken off. that may be why the battery consumption is high
Even after turning off and on the watch the HR sensor keeps blinking continuously. It NEVER turns off in my case since SW 3.60... And the measurements are very unreliable. Today It measured 165 bpm while I was only zitting behind my desk.. Yesterday It recorded 1200 (!!!) active calorie because of incorrectly high heartrate reading... Ridiculous, because I had the day off and I did absolutely nothing else than some reading, cooking and watching tv. Vivoactive 4 estimated over 3200 calories for that day instead of 2300 it should appr. have been.
I don't trust the thing anymore and regret my purchase.. A shame, because my vivoactive 3 was a great watch!!
Maybe you have some other settings which triggers the HR sensor. In my case (3rd test today) it happens only after recording an activity.
Maybe MoveIQ is the cause? Do you have it enabled?
