Race S: Extremely high battery use rate

gagbo

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:

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

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
