Race S: Extremely high battery use rate
-
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

@gagbo said in Race S: Extremely high battery use rate:
I lost 29% battery (from 100 to 79)
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… -
FWIW a soft reset after using the chest strap seems to mitigate the issue…
