Race S: Extremely high battery use rate

Wilson75

@sky-runner my polar h10 retired so I didn’t use external HR for few weeks and didn’t not notice any issue with the battery drain.

Now I have received my new h10 polar I am losing more battery per day with no change in my sport and settings.

E.g watch fully charged Thursday evening and Friday commuting with 1h30 sport. And this Saturday morning I have 80% battery…

Still something behind the scene here.

Can confirm that also on my Race S I have battery drain. I’m not using vector watchface but have a polar H9 paired and using it almost at every activity. Still battery drains with no activities. Charged Friday 18:00, Saturday 10:30 it’s at 84%. Can we get a feedback that someone at Suunto is looking at it? Thank you!

Seems like Suunto and Polar is not a good combination judging on several posts about problems with a Polar HRM…

@2b2bff using it since day one of my race s and dind’t have any problem till now. Maybe i was lucky!

@Michele-Sella have you upgraded H9/H10 to the lastest fw?

Michele Sella

@snow Nope, didn’t know i could do that! I’ll do it now since tomorrow i have an activity planned. Will let you know if it changes anything. Thanks!

I’ve had similar issues with Coros HRM (armband sensor).

@Michele-Sella Both Verity Sense & H10 work flawlessly for me after updating. A friend of mine is facing issues though with BT (signal drops).

I have had the same problem for 6 months, I tried to RMA the watch and got told that everything is fine, I’ve put the watch away and went back to my Gatmin FR255. After the “November Drain” update I tried the watch again, (with a soft reset, low brightness, no always-on) and I still had crazy battery drain.
I’m considering trying again now because it feels bad having the watch here and not doing anything, but apparently there are still issues since the post here is recent.

As far as I understand, the current state is:

Maybe having an external HR paired drains battery? I will use a strap anyway to have precise measurements so I guess I can’t do anything about it
Maybe using some watch faces drains battery? I should use the default Race S one?
Maybe 24/7 HR messes the battery up ? I wear the watch all the time, but the working hypothesis is that the sensor loses contact with my skin (or struggles in general because I’m black?) and that makes the sensor go nuts on light emission?

I’m trying to find some leads that would make the watch usable for me, as I’m too forgetful for a watch I must recharge every other day

@Tieutieu Haven’t tracked it, but I noticed this too! (SV2)

Confirmed on my watch too. Before sleep was 15%, in the morning 9% - DND on, 24/7 HR, lastest software 2.50.28.
