@runyx17 I’m not sure that’s the case. There was a glitch with the Suunto 9 Peak Pro a while back that was fixed via a quick update within a month.

@Łukasz-Szmigiel Haha! We were writing the same thing at the same time. Sorry I jumped in.

@duffman19 So I tried first with a short stretching activity. Delete from SA, log out of SA, login again, resync and it showed the activity again. However. doing so with my long run, seems to not resync although it’s still on the watch (at least showing on the watch. I noticed. Daily HR, steps, resources are all in SA including the activity time. But GPS and activity stats are not. Would be great to ad Fit/json manualy Back into SA. That’s possible? Is it possible json and fit files are deleted if you uninstal SA?? Would be an explanation I can’t find them on my phone anymore.

@Thorlap71 Personally, I haven’t tried it. Someone I spoke to did it and I still haven’t received an update from him on whether it had any effect.

@duffman19 Thank you, curiously, the navigation still worked exactly. But it makes sense what you explain. Thank you

Regarding step counts, I still think for those who are highly focused on that, getting a waist-based model will likely give better overall accuracy that the majority of watches and is fairly inexpensive. Here’s a quick article to show the style I mean: https://www.verywellfit.com/best-pedometers-4159148 I know people who do activities like knitting or drumming that would get a lot of “accidental steps” if relying on any wrist based model. My own attitude is simpler — steps cannot tell me intensity of effort. The other day I did 5082 steps for one activity, which was a walking effort of 5km with average HR of 92bpm. Then another day I did another 5km effort doing track intervals (100m x 10) which was less steps 4461 but higher average HR of 154bpm. If I were only looking at steps, the second effort seems “weaker” which is the complete opposite result of my own analysis. Of course, the walking session was good for recovery, while the intervals was just a general intense workout. And today we have thunderstorms outside, and while I’ll get a decent amount of steps just going through the house, my primary workout today will be a rowing session which technically is “zero steps,” and yesterday was an hour long cycling workout that also was “zero steps”. Now I know in the Polar ecosystem they have a feature where they can give you “step equivalents” for things like that, but I dislike that system.

I’ve noticed that significant battery drain is caused by the 24/7 heart rate monitoring mode. Previously, the watch would measure heart rate every 3 to 5 minutes; however, after the software update, it monitors continuously—24/7—without any breaks unless you take the watch off your wrist.

@snow had it from May last year & until June this year it was fab, no issues whatsoever. Just since June the issues seem to have been. Updated the app, software, etc, used S+, not used S+, but seems no pattern

@Sascha-Domres makes sense, I get your point but it is more like I would buy Coros Apex 4 or similar and go to their community and start complaining that they do not support “tags” on activities and I am so dissapointed in all they do

@sky-runner Could share the gpx of that route? I could ask about this behaviour. mp if preferred.

@Tamás-Tompa, it wasn’t done in past years, I really doubt that they’ll do something now.

I reported this, it seems a backend/app issue of some kind because it affects watches with all firmware versions. Let me know if it happens again next week (it happened to me on Friday), but I believe it should be fixed soon.

@Brad_Olwin I always run 2-3 days after races. Only for all-out Marathons, I take two weeks off. My HR is not really influenced by these races. It is not more than the usual ±4 bpms during easy runs at aerobic LT. Of course my legs are tired and the muscular effort feels way higher for the pace but HR is the same for the speed that I run. I would be then not able to run for long time at my LT but due to fatigue. HR is then still in the expected corridor for that pace. Only experienced strong deviations of LT HR at return to sport after stronger infections like COVID and always the first 3 days of winter training camp on the canarien islands. There my body is always completely overwhelmed by the sudden 25°C temperature difference. SZ though told me so many times, I would be way above or below my threshold even though RPE, HR, and pace was exactly as expected. During the training camp SZ always told me that my Real-Time effort should be way higher. No way that I could ever run under that sudden higher temps at that HR which was close to my 1k all-out HR. Real-Time effort does not work at all for me, while average reported thresholds over more than hundred activities come close.

@sky-runner @runyx17 And I’ll say it again, on the chance someone out there is listening: Removing the auto-reverse “feature” would solve almost all of the navigation issues.

@Mff73 Thanks, I’ll test it again. With every long press I should come back a view. Understood! As with Maps Zoom . But in fact I always came back a level but never again to the initial overview of the complete altitude curve of the complete route.

@Klaas Can you upload the dives log file (json) to Claude AI and ask Claude the simple question why the algorithm deviation occurred? Can you let us know the response?

@GiPFELKiND said: @johann.fuehrer thank you! I will try this ️ I always clean my Suunto watches like every week with normal soap, old hand brush. Daily just with water only after training. Looks like new

@isazi LOL! Damn you Jay!

@Egika Thank a lot you for this initial explanation and clarification. However, this information dates back to 2022 and mentions an improvement with the Suunto 9 Peak Pro. As of May 2026, my question regarding the Suunto Race 2 remains unanswered.

@zt_zzzzz Thanks, right now I don’t have an ambit 2, if someone wants to spend sometime sending my some files about them I will happilly integrate. Edit: first release https://github.com/skinnie/sommet/releases
