Race S: Extremely high battery use rate
-
@Tieutieu I think you’re right about that. I didn’t notice significant battery drain until switching to the Vector face. Switching back to the Race Flow to see how things change. It would be interesting to test the battery drain between charges with the different faces and see how they compare.
-
@atoponce I’m on a simple analog wf and I keep seeing fast battery depletion. That said, afaic it seems to depend on when I use an external HR chest strap.
-
@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?
-
@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.
-
I just tried:
- Race 2 Watch face, with always on display
- 24h after charging, 1h20 of GPS activity (biking with a chest strap)
- 24/7 heart rate (but no SpO₂)
- wore the watch the whole time
I lost 29% battery (from 100 to 79)
So long and see you next software update for another try, I’ll go back to my forerunner 255
-
@snow so charged the watch 100% Sunday morning and got 75% after 5h activity with tracking and auto pause. Then no activity only kept the watch with me, now it is Wednesday 21:00pm and I’m at 10%. Seems still high consumption to me. I remember I could get 6/7 days of battery life without activity.
-
@Michele-Sella Yes, the battery use is easily twice as high as it used to be.
For example this morning during a 40 minute gym training without GPS it went down (according to the information stored in the FIT file) from 33% to 31%.
7 hours later the watch is already at 23%. That isn’t normal by any means! AOD is off.
-
@Michele-Sella I thought a factory reset would definitely fix the problem, but unfortunately, it’s gotten even worse now. I could be wrong, but as I said, it seems to depend on when I start using bluetooth. Now I restart the watch after every use of the chest strap and GPS just to see if anything changes. I hope Suunto starts looking into this regression
As @sky-runner says also for me AOD off and even 24/7 HR off to save battery now

Thats 21% and expected as the watch with AOD will only get about 5 days - less if actually used…

@2b2bff my bad, it was to 71%, one too many 9
But I guess counting for 80min of GPS and 24h of AOD that would still be within spec (30h GPS is 3%/h and 5d AOD is 20%/d so 23 vs 29) I guess I misread the specs
-
@2b2bff I currently observe about 20% loss per day with display wake on wrist (no AOD) and all other settings being default. For example, my watch lost 22% (from 31% to 9%) in the time period since 9am yesterday to 11:30am today.
According to the website the expected battery life in smartwatch mode with these settings is 9 days, but the real battery life is about twice as short.
