Race S: Extremely high battery use rate

sky-runner

24 hours ago I charged my Race S to 100%. I had 3 runs with the total duration of about 4 hours with external HR. The battery is now at 66%. This doesn’t seem normal at all. By the way, last night it was at 80%, and after that I had only a short 20 minute run. The first two runs were with external HR, the last run with WHR.

4 hours of running should account for 13.3% of battery use. That means the battery discharged over 20% in the remaining 20 hours.

@sky-runner I have a similar « high » consumption on mine since last update. Soft reset didn’t solved. I wait for next update to see if it changes

@sky-runner similarly here on the vertical https://forum.suunto.com/post/186853

@Tieutieu I really wish this is fixed soon! I don’t experience this issue all time but it comes and goes. I do suspect it is related to the use of the external HR sensor.

By the way, in another 7 hours the battery level has dropped from 66% to 50%.

Also, what nobody mentions is that this reduces the longevity of the battery. The battery has only so many charge-discharge cycles before it starts to lose capacity, perhaps about 300. So this isn’t just an inconvenience.

@sky-runner same problem. After sleep from 100% to 80%. Any fix?

@sky-runner Same. I had it charged to 98% this morning. Just completed a 55 minute run, with external HRM and Stryd. Battery is now 91%.

@sky-runner ditto!

24 hours later, 77%. I’m monitoring HR 24/7, but display is off and awakes on raise.

@sky-runner I am having the same problem, battery is draining ridiculously fast. Battery last 2-3 days instead of a 1-2 weeks with my usual activities. Race 2 with 2.50.28.

Tried a factory reset and now it’s even more noticeable…

I can just confirm that there is higher battery consumption on my wife’s Race S. It’s a reoccurring problem. In one update it seems to be fixed, then again introduced in next one.

48 hours in, and it’s at 50%. I did an 80 minute run yesterday. Today is a rest day for me, so perhaps it won’t drop 20% or more in the next 24 hours.

Tieutieu

To be noticed : battery consumption is more high with new vector watch face. I turned back to Hike watchface I was using before.

atoponce

@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…

Michele Sella

@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?
