Maybe it’s easier to create a Guide and treat each stage as an interval? Thanks all!

@babychai said: @KSGravelJunkie I’m speaking based on my own two time experience with both the SV1 Stainless Steel and SV1 Solar Titanium. I let the battery drain completely to 0% (until screen off or seeing the battery symbol), then fully charged it to 100% and kept it charging for another 1 hour. Based on my experience, starting the charge at 5%, 10%, or 20% and unplugging the charging cable immediately once it reaches 100% never worked as well for me. This. Many times this trick repaired my battery drain in all Suunto watches.

@sunter usually I test a new firmware version or two every week. I know people believe that development at Suunto is slow, but it is not.

@scotta same here upgrade was a little longer than the advertised 10 minutes but so far no issues encountered.

@Triumph114 should be under weather, but probably not there yet for Ocean (next firmware update).

@sindavide said: @elbee Ok, then it’s the watch. Did Suunto offer any solution? By the way, while the Smart Sensor is being repaired i got another one, used yesterday for biking and today for swimming, seems fine, no disconnections They told me not to expect a fix by a firmware update anytime soon. During my training yesterday I also didn’t had a disconnect. Have to say, only the heart rate sensor was connecten. The battery of my stryd was empty (after my vacation I didn’t check). And I started with frequent reboots, also to see if that mitigate the battery drain problems. (after a forced reboot due to a complete empty battery after a hike caused by the battery train, my battery usage is quite okay)

@Louise-Roo According to the user manual, it seems that the Suunto Run isn’t compatible with external sensors others than foot pod and HR : [image: 1788355395078-00b5dee5-b0a6-4c04-b0f8-f9aff5605e01-image.jpeg] But weirdly, on the french spec sheet, it talks about being able to use power meter for cycling : [image: 1788355492595-6efeeae0-edf6-4805-8cc0-b13b1934ff3b-image.jpeg]

@André-Faria I can’t access Reddit from work! I’ll look now (I was being impatient!)

I’d just be happy if they could go back to the status prior the update that broke it. Battery life on my Race isn’t an issue at all. Actually it runs so long that I almost forget that it needs to be charged from time to time

A new relase is aviable : *Release notes 2.56.28 Staged update starting on August 31st, 2026 This update improves software stability and includes several bug fixes Improvements: Improved overall stability Fixed an issue where pool swimming distance and duration could be displayed incorrectly in certain scenarios* I hope this will correct the bug !

I have a race s. I use it with vibration as a coach… to run a drill with a group and know when to move to next, using the countdown or intervals. I want ideally to see this visually on the watch screen. The outer ring is the most preferred. For some watch faces they do show a small countdown graphic but it’s no where as good. I might be an unusual user but I bought the watch really for vibration and countdown. It works but the visual is poorer than rivals. Most frustrating though is for a few days I had the outer ring working exactly as I wanted. Then an update came through and changed it. I’ve tried everything but can’t resolve. I checked online and it’s mentioned as a reason why some people don’t buy Suunto.

Too late for UTMB, but this (as guessed) it was an App and not a firmware issue. It has been fixed, not sure when everyone will get the next App version.

I fully agree with this feature request, and i ask you to approve it. I have owned the original Suunto Core All Black and one of the features I valued the most was the Weather Trend Indicator being visible directly on the main watch face. This was extremely useful because you could simply glance at the watch and immediately see whether atmospheric pressure was rising or falling, without having to switch to the BARO screen. For me, this is one of the main reasons to own a Suunto Core rather than a regular digital watch On the Core 2, the weather trend indicator still exists, but having it only on the BARO screen significantly reduces its usefulness. When you are already on the BARO screen, you also have the pressure graph, so the indicator is much less valuable there Could Suunto please consider adding Weather Trend as an option for the lower secondary field on the main watch face, alongside Sunrise/Sunset, Moon Phase, Steps, Dual Time, etc.? This seems like a relatively simple firmware/UI change, and it would make the Core 2 much closer to the original Core experience. Please bring this back in a future firmware update. It would make a big difference for long-time Core users.

@surfboomerang Thanks, it is ok now!

@MdzOtt Thank you for the info. I was just wondering if the connection would persist, when no S+ Apps are enabled. Just to find out if there is any connection between the issue and the S+ Apps. But now we also have the new software, where we do not know if an improvement for the connection drops was included or not. So two Options to test. btw, I think the ZoneSense App is not necessary anymore, as it is included as “standard” Data in the trainings.

Hi, I have a strange HR measurement issue with my Suunto 9 Peak Pro. I use latest FW version 2.50.28 During continuous cycling, the optical heart rate measurement works perfectly fine. However, after I stop for a short break (around 2–3 minutes), the HR reading becomes completely inaccurate when I start cycling again. For example: Before the stop: watch shows 130–150 bpm, which matches my chest strap. I stop for 2–3 minutes. After I start cycling again: the watch may show 50–80 bpm, even though my actual HR is still around 130–150 bpm. The incorrect reading can continue for many many kilometres. I have confirmed this using a chest strap, so it is definitely not my actual heart rate. Interestingly, the green optical sensor LEDs remain active, so the sensor does not appear to be completely switched off. It happens when I recording activity as cycling as well as I am not recording an activity during these rides, simply use the HR display on the watch face. Has anyone experienced the same issue? Is there a known problem with the OHR sensor/firmware after a period of inactivity or standing still?
