For me on Suunto Race 1 TrainAsOne guides stopped syncing to watch two or three app versions ago. Don‘t know exactly but maybe three month ago. This is very annoying!!

@tomvanacker Press lower button to enter Control panel Scroll down to Power saving and disable

@athinakap30 memory. You’re handling a very low resource device that has to do plenty of hard work every second to display accurate workout data - while being active for 70 or so constant hours on one battery charge. Suunto+ apps can be very demanding, especially if you want to draw something more than just a number.

@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)

@HonzaS Today had to send also the HR smart sensor bought two months ago. Let’s see how it goes this time. Glad to hear more people had good experience with service

try removing all Guides and sync again other Apps and Watch Faces. If that doesn’t work, a hard reset probably will…

@Thomas-Gilquin never experienced something like that, but since a couple of weeks there is a “similar” issue with climb guidance in the zoomed segment where no profile is visible (see https://forum.suunto.com/post/195432). Your doesn’t seem to be the exact same problem, but who knows, it can be somehow related if this is a backed issue from Suunto servers.

@johann.fuehrer for me the soft reset after charging doesn’t help with battery run time. But it certainly helps with Resources. Will keep doing it…

@isazi … and the same happens on the Vertical 2 with powermeter connection as well…

I come back to this topic, 2.53.42, seems like watch never gets my sleeping time and wake up time correct. I am off on my schedule, but I am moving, changing menus etc, kinda don’t understand how can the watch say I am sleeping. Is there any “manual” of good practices to not be like that or it will be corrected? In the previous firmware ª(on which also my sleep routing matched more the watch schedule routine) it worked ok for me.

@Tieutieu Battery drain: Same here

​Hi everyone, ​I contacted Suunto Support regarding an issue with Heart Rate zone distribution and TSS calculations for activities synced from my Hammerhead Karoo unit. ​Currently, third-party imported activities ignore custom HR zones set on the watch and instead rely on Suunto’s default backend algorithms. As a result, rides synced from my Karoo end up with mismatched HR zones (e.g., shifting Zone 2 efforts into Zone 1), which directly distorts HR-TSS, CTL, and ATL tracking in the Suunto App. ​I strongly request that Suunto allows manual HR zone configuration directly within the Suunto App (or enables synced activities to respect the watch’s custom HR zone settings/LTHR). This would ensure that data imported from head units like Hammerhead is categorized accurately. ​Below is the official response I received from Suunto Support confirming this current limitation: Thank you for contacting Suunto Support and for providing the detailed information. We understand that you are recording cycling activities with your Hammerhead Karoo 3, which are then automatically synced to the Suunto App, and that you have noticed differences in the heart rate zone distribution between the Hammerhead platform and the Suunto App. Regarding imported activities from third-party platforms, the heart rate zone analysis displayed in the Suunto App is calculated based on the settings and algorithms used by Suunto. The HR zones configured on your Suunto Race S watch may not be applied to activities imported from other services, which can result in differences between the original platform and the Suunto App. At the moment, the Suunto App does not support setting independent heart rate zones specifically for imported third-party activities. Therefore, there is currently no setting available to force imported activities to use the HR zone configuration from Hammerhead. We appreciate your feedback regarding this functionality. We will forward your comments to the relevant team as user feedback for future improvements. Thank you again for your understanding and support. Kind regards, Suunto Support Team

@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

@Ecki-D. I sync to Strava, crop there, export GPX, load it to Sport Tracker (after deleting the original). It works, but it is like trying to scratch your left ear with your right foot . Btw. This feature was asked for for at least 10 years

@2b2bff it happens the same to me, but I haven’t understand the pattern yet. Sometimes I see only one activity type, sometimes more than one. The only thing I have discovered is that the summary discards always at least one activity, it is never complete.

@athinakap30 With every new software update, the battery gets worse; no matter what setting you use, the juice doesn’t last as long as they are claiming. The last battery issue was addressed in firmware version “2.48.16”, and later firmware versions have been pathetic for battery performance, and Suunto engineers have ignored it royally (busy developing more bugs ) I have been suffering from this issue for a very long time; resets, factory resets, and firmware rollbacks have not worked. Every time I do that, I spend more time reconfiguring whatch.

@isazi Yeah, let’s hope they implement it as soon as possible.

@Goatee Suunto reached out to me via email asking for more information (watch serial number, app version, etc.). I sent them the deets, so I’ll see where things go from there. Hopefully we can isolate the bug and get it fixed.

@Kowalski I’m waiting for a successor of the Race S as well, decided not to go with the Race 2. But it felt surprisingly small for its size…
