@pavel-samokha said in Software Update 2.39.44 (2024 Q4 Hotfix + new pool swim algo):

Staged update starting on February 10th 2025 for Race S, Race and Vertical

This update brings improvements and bug fixes.
Improvements and bug fixes:

Pool swim distance accuracy improved

Daily HR and sleep tracking problems fixed

Stability improvements and bug fixes

One WiFi connection problem fixed

Not yet for Suunto 9 Peak Pro, still being tested

I found one more problem with a new firmware.

If I create structured workout, the watch doesn’t count how much distance left and therefore cannot show me next steps, if it is distance based workout.

For example, if according to training program I have to swim 100m and I do that, at the end the watch still show me, that 100m left.

To demonstrate this I recorded this short video:
https://youtube.com/shorts/El_WJFhMOmY?si=Kk6KUz9FO3GZI5bO

Here just as example I created workout with 100m distance. I “swam” 25m (imitation). The watch should show me that 75m left, but they still show me that 100m left.

During actual swimming training today I had the same problem.

On previous firmwares it worked correctly.

Today sleep tracking failed. Was the first time since this update. Don’t know if it is the same bug or a different one.

Jordi C · 26 Feb 2025, 12:32

My sleep tracking has failed for the second time in a 3 days period.

dulko79 · 26 Feb 2025, 16:15

@Jordi-C my race s tracked sleep just fine after the fail the other day. After the fail I did soft reset. Did you do soft reset?

Jordi C · 26 Feb 2025, 17:56

@dulko79 Yes, yesterday I did a soft reset.

This morning my sleep tracking was detected as a nap, followed by a short period of sleep, I have to say that the battery was very low, around 6%, when I woke up, I don’t know if that had anything to do with it.

I charged the watch to 100% and went for a walk, after the first kilometer I realised that my watch was not detecting my HR.
I had to stop the activity and do another soft reset to make everything work properly.

The truth is that the last 2 updates are being quite messed up.

The issue with the hr being stoped it is really bad . I have had it twice already .

SergioB · 28 Feb 2025, 06:06

As other users, for the second night in a row my Race detected a few hours of sleep followed by a couple of hours of nap. This is the first time I have issues after this update (which seemed to have solved the previous one I had, where sleep tracking wasn’t working at all)

Ars Vitae · 28 Feb 2025, 12:22

@Devis I confirm. In my recent training, it is clear that the watch did not recognize a single length in the backstroke style. There must be something in that. Swimming in the pool is, in my opinion, the Suunto’s weakest point. Despite the many advantages of the watch for those for whom swimming is an integral part of training, the unresolved accuracy problem must be a major disappointment.

althaea35 · 1 Mar 2025, 05:46

After attempting many different fixes, sleep tracking, HRV, and resources have become too ‘hit and miss’ on the Race for me. I am downgrading to the previous firmware.

Have others done the same?

Outdoorsy · 1 Mar 2025, 05:46

@althaea35 I stopped updating firmware. My SV is at version 2.33.16 and works great for me.

Tieutieu · 1 Mar 2025, 06:31

I have absolutely no issues at all with both my SRs and SV, with latest fw.

Elmiuel · 3 Jan 2025, 12:27

Hello mates.
I already got the reading error last night, a nap reading was recorded (1:13), no Vfc…
The usual setting in RACE is not to disturb, the night before I installed the vertical week screen, nothing more. Another detail, but I don’t think it’s decisive, is that the battery is at 36%…
I will wait another night in case the failure occurs before the software degradation…I like to have information from Vfc daily, I imagine like you
…Hi, something very strange. At 1:30’ after getting up, the reading for last night’s sleep appeared…other times it had been within minutes but this time I had time to publish the lack of readings…

ChrisA · 3 Jan 2025, 21:12

@Tieutieu almost the same here, sleep tracking works and worked before the update and afterwards as does workout tracking on the Race S. I had one occasion when OHR stopped working after I started a workout (green light was on, but HR stayed at some value and never changed). Restarted three times and in the pre-workout screen HR was shown but then got locked immediately after starting. Took down the watch, cleaned sensors and wore it at the inside if the wrist which suddenly fixed the problem

Coming back to battery drain with the firmware .
I do observe much higher battery consumption . It is similar to the pre previous firmware when the big issue was reported .

So far this version has strange oHR behavior (losing hr measurements during activities with no apparent reason) and the battery is really not that great despite leaving the watch to do this calibration with running out battery and recharging

Anyone with similar results ?

Thanks

SuperFlo75 · 3 Feb 2025, 07:48

@thanasis I think you are right… it seems that the battery consumption of my SV is to high now…

My observations after second and third battery charge cycle after updating to latest firmware and have done a recalibration.

Yes, I’m too observing higher battery consumption compared to two firmware versions back.

The ohr stopped once during sleep tracking since updating to latest firmware. This same behavior was experienced during last firmware too. It seems a bit better than previous firmware as it happened more during last time but this issue didn’t at least for me happen two firmware versions back. The behavior seemed to happen at random.

There was a week where 4 days the ohr just measured the lowest zone no matter how fast I ran. I washed the watch and cleaned it and the measurement started working again. My conclusion here is that there might been dirt or something interfering, so this one I’m not blaming the update.

The watch froze once during a long run (30km). Must have run 20km and it froze completely. Half of the screen was black and I had to soft reset. The distans up until 20km however got recorded on the Suunto App but the next 10km I manually entered as I didn’t have time to stop and fiddle with the watch. Have been on long runs after and it has not frozen up and everything seems ok as of now. This happened so randomly too.

So yes, I’m too having some hiccups regarding the ohr and battery consumption on the latest firmware.

Thank you! Have posted my experience regarding that specific issue there too now.

Łukasz Szmigiel · S9PP 2.40.44

I’m on 2.39.20 on 9PP and I was suspecting a higher battery drain too.

Today I’ve checked in my little app the battery drain after my 1+ hour long walk and the estimate is around 20 hours instead the typical 38 - 39 hours.

There’s nothing fancy running on the watch, one face and a sun s+ app.

Александр Даниленко · 3 Mar 2025, 01:58

Today I did my swimming training and the watch counted almost perfectly - I swam all swimming strokes + medley + sprinting.

Again, with structured workout the watch didn’t count how much distance left for the current step of the training program. I explained this problem in my previous post here.

But today I would like to point out on another problem. For some reason the watch didn’t count the average pace. It is not the first time. Previous I was thinking it is because specific of those trainings (moving time was small).

But now it wasn’t that small. And still:

And I also checked what is uploaded to strava:

Look at moving time and pace. There is definitely a bug there.
