Race S: Extremely high battery use rate
-
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.
-
@sky-runner I have AOD enabled and get about 4 days, I guess. So, not extremely high, but mabye a bit more than it used to be…
Next update is around the corner, so let’s see what it gives us… -
A soft reset after using the chest strap seems to mitigate the issue…
Edit: yesterday at 6 pm I updated the watch (version 2.53.42); the battery was at 40%. I went for a 30-minute run wearing the chest strap and didn’t perform a soft reset afterwards. This morning at 6 am the battery was at 36% (sleep, hrv enabled). So far, so good, I’d say
Edit: after four days of heavy use, afaic the battery is holding up well so, barring any last-minute surprises, I’m happy with it now
Edit: the last one I promise. Today I went trail running for an hour and 40 minutes with the navigation screen on the whole time. The battery dropped from 86% to 79%

Feedback after updating my SRs Tuesday. Extra battery consumption seems to fixed to me and back to what is was on daily use. To be confirmed
-
I can confirm now : extra battery drain on daily use has been fixed

@Tieutieu I am not so sure! I have a new Vertical 2. At first the battery usage was excellent. But once I connected and used Coros armband HR sensor for the first time, the battery consumption has increased to over 10% per day in smartwatch mode. The battery was at 55% yesterday. One day later, including a 1:30h run, the battery now is at 43%. A different watch but the same issue. That doesn’t seem normal!

Before this update, I had noticed a significant drop in battery life, and the only solution I had found to mitigate the issue was to perform a soft reset after using the chest strap. After the update, I also performed a factory reset, and now afaic the battery is working properly

@sky-runner this thread is in the Race S forum and has Race S in the title. I guess it is related to the Race S then?

Not necessaraly. There is a generic race s topic on this forum, but not a generic battery issues topic. It only means people with a race s complain, but doesn’t imply the problem is hardware, software, settings or user related.
-
@elbee I mean all the Race S people say: It is fixed. Then a guy with a Vertical 2 says: no it is not.
There are other Battery drain topics, but this one has been for the Race S.
-
@Tieutieu Not for me. I’m still seeing 20% drain per day.
