@VoiGAS It all depends on the internal and thus battery temperature. You can easily check the internal temperature by looking at Alti/Baro/Temp widget after some time in direct sunlight. It depends on the ambient air temperature and also largely on the amount of infrared radiation the watch is exposed to. For example if the watch is in the interior and behind IR blocking glass window, the internal temperature would be very close to ambient temperature considering the very low charging power generated by photovoltaic panel. If this is let’s say between 20-25°C ambient air, that’s way more favorable for long term battery health than on the wrist temperature of ~32°C (currently on my wrist). Leaving it directly outside is of course a bad idea for prolonged periods, unless you can compensate by low ambient air temperature that keeps internal temperature from raising to unhealthy levels.

Its seems the Nautic S gps is more accurate than the Nautic regarding 3D MAP ive used the Nautic S on left arm and the Nautic on right arm The dive profile 3D on the Nautic S translates the dive we did. There was some illegal fishing traps/rope in Marine park and we went to “investigate” and return to the same place using the same rope from fishing traps The Nautic GPS route deviate a lot more than it supposed to… Something that the software team should investigate… Nautic S [image: 1772484057129-img_0097.png] Nautic [image: 1772484083600-img_0098.png]

@Angusmil Max Heart rate is 220 - minus your age whats the resting HR the watch shows ?

@Nelson-Diogo I have seen this as well and filed a bug with Suunto. They are aware of the problem. When this happens again send your logs to Suunto and note the problem. You can DM me with the time and date your logs were sent, please note the time zone as well and provide your Suunto app email (username). I can make sure that the information gets to the right developers.

@paolo-1 Use RunGap, it will upload all Apple Workouts or Strava to Suunto. You will have to pay a small fee and you can find RunGap in the App Store. In the future add SportsTracker app to your iPhone and Apple Watch and connect the Apple Watch. SportsTracker is developed by Suunto and will automatically sync Apple workouts and SportsTracker workouts on the Apple Watch to the Suunto app. SportsTracker and Suunto app share the same database.

More than two years after the latest post (which wasn’t answered) I just had the same issue. Bought the S9PP end of last years as it was in sale and I thought meanwhile all SW Bugs should have been fixed. Send logs to Suunto. How to rely in that watch for things like Everesting? During the last three months three soft-resets were necessary. My son bought it about four weeks ago and in last week he deserted it four times. As said a few posts above: this is annoying

I love this Watchface! Clean & Simple SUUNTO. It’s not just a watch, it’s an attitude. [image: 1772452582162-img_4369.jpeg]

@Philip A €100 watch can display many metrics, but that doesn’t mean the data quality is comparable. More numbers do not necessarily mean better measurement. We don’t know exactly which computational models Suunto uses on the Vertical 1. Sleep and HRV algorithms are strongly tied to the hardware, especially to the OHR sensor and signal quality. The Vertical 2 uses different hardware and a different optical heart rate sensor. It is plausible that any algorithmic evolutions are designed around the newer sensor and are not backward compatible with the Vertical 1. For this reason, realistically, it is difficult to expect major new implementations on the V1. Future developments are more likely to focus on the newer hardware platform. The price of the device is not the decisive factor. The hardware architecture is. EDIT: From the photos, the Suunto Ocean sensor appears to be the same as the one in the Vertical 1, and the Ocean does report deep, REM, and light sleep stages. So, in theory, the Vertical could inherit those features. That said, I may be oversimplifying. Even if the hardware looks similar, firmware architecture, signal processing, and model calibration can differ significantly between devices.

@sky-runner oh you are right! sorry, my bad, I thought there was an app for segments Hope you get some answers!

@todgerama Just curious… what was the solution after those replacements? Did they tell you to service the watch regularly with some silicon oil (I suppose) applied to the base of the buttons? I bought this watch for this purpose only I cannot accept it that it leaks water inside nevertheless.

I have the same issue…randomly, my S9PP shows out vibrations and sounds with no reason (no rules and no constant timing). I just set the DND mode to avoid that annoying attitude.

Installed the latest version 7.6.0. I have found that the option Turn-by-turn when activated it seems the route is more stable.…[image: 1772441983530-capture-d-%C3%A9cran.2026-03-02-%C3%A0-09.56.20.jpg] Not used to activating this option

Anyone? Was this a ridiculous enquiry? I mean the Suunto app recognises a Pulse heart beat sensor, why not a Wahoo bicycle cadence sensor? Wahoo says any app which recognises smart sensors should recognise their sensor. ‍️

@VoiGAS Good to hear it. Enjoy.

@Fabii85 unfortunately not - moved to Garmin back. No sync issues, more reliable sleep tracking (time, feeling - taking notes in the morning, and comparing with data a week later). I miss the look of Race 2, and the UI. But having the data in sync was more demanding.

Also bit he bullet and did a factory reset. All works fine now, but it was a pain. Realized how much I customized the settings… let’s hope it’ll keep working stable now.

@PetrMisek If you swipe across the graph, the app shows you the legend for each bar. Red indicates very high stress.
