HR/SpO2 odd sensors behaviour?

Hi there,
I own this watch for a week or so and I‘m still tinkering with it to understand all its functionalities. That said I’ve run up against an odd (bug?) behaviour. I do not use daily HR so it’s switched off. Now, from the time watch face if I start scrolling down to see my instant HR, watch starts measuring. So far so good but If I keep scrolling down the menu to see e.g. the altitude or step counter etc. the HR and SpO2 sensors remain active and they stay there until I return to the watch time face.
Moreover if I decide to use the daily HR feature, the watch takes a big while before starts activating the HR sensor.
am I missing anything? Thanks.

Sorry, should I therefore assume that since there are no answers, this is normal behavior?

Thanks.

@gi0vanni mine works the same way. I also don’t use the daily HR monitoring.

@isazi I contacted support and was told that it should not work that way and to try a factory reset… well, at least now I know that my unit is not defective.

@gi0vanni not sure a factory reset would fix this, I believe it is how it works. Maybe it was meant to work like this, I will ask.

indeed!

@gi0vanni I reported the issue and will wait for an answer from Suunto. I believe this is how it works, but maybe it is a bug and the lights should turn off immediately after switching to another widget. Will let you know.

I would suggest you to not factory reset the watch in the meanwhile.

I agree

Will let you know

thanks a bunch!

It always worked like this.
There should be an old thread for Spartan I guess

@sartoric I also think this is how it works, but maybe it is not how it should work. I should have an answer tomorrow.

I am pretty sure this is how it works on purpose as well.
Getting a heart rate reading takes some time. So while you are in the menu, the watch is kind of prepared to show the current heart rate and keeps measuring. Seems like a deliberate design decision to avoid multiple waiting times while passing the HR widget.

@Egika I see, but even if you wait for sensors do their job they still remain active if you move on the next widget

Egika

@gi0vanni yes. maybe not fully clear.
If it stopped working while you are in the other widgets, it would always need waiting time when passing the HR widget.

isazi

Apparently this is not a bug, it is implemented this way and will stay this way. I also find it weird and a waste of power, and believe most users are not going up and down to check their HR all the time, but anyway.

IMPORTANT do not reset your watch as told by support, this is the normal behavior of your watch.

@isazi No what a pity! I hope the ability to turn the widgets on/off comes sooner or later…
Thanks anyway!
