@runomatic [image: 1765346821073-sn%C3%ADmek-obrazovky-2025-12-10-v-7.05.02.png] I went cross-country skiing for 2 hours. Average HR for 2 hours was 149bpm (H10 strap). Resources went down pretty quickly (finally ) but i don´t understand red stripe - under load, this was 45 minutes after activity and it is bigger than blue one before it, so resources are going up when I am under load?? Strange

@pavel.samokha My iOS 15.8.5, Suunto App Version 2.39.1 (16998), email: <redacted>, Username: kosmarikas. Watch: Suunto Race S, Software version 2.48.16. Here some screenshots:[image: 1765314962264-img_8062.png] [image: 1765314962282-img_8061.png]

this thread is about HR belts smelling funny, not about issues with the data. Please stay In Topic

@Sportsfreund Yeah! I think this is known by Suunto. I have the problem as well. There was a problem with the 9 Peak Pro. It just erased all the watch faces. Suunto fixed that in a few days, but since then the watchfaces are not shown in the app. On the watch I don’t have problems

@Steven-Hambleton from a few posts I read here I can see your initial enthusiasm about Suunto faded very quickly. What happened? Sorry for the off-topic. Well done @Nikolai-Simonov !

@Tieutieu but the problems were not solved

@2b2bff Thank you

@enriqueescoms There are two times, one for the whole activity and one for the time you actually swam - the watch will break your swim in intervals if you stop…

Hi, I’m having issues again with HR data not being recorded in the last part of the activity. There have now been consecutive updates all at the same time, so it is difficult to understand why the problem has occurred again. I’ve updated the Polar H10 to latest fw, 4.1.10 I’ve updated SA to 6.5.7 (Android) I’ve updated the Run to 3.22.24 [image: 1765211731887-run.png]

I also noticed that the temperature bar values aren’t updated until you unlock the watch

@Armin-M it’s funny because it is just the way from the watch to the Phone not working. Information from the Phone to the watch worked well.

@Jaxxdu I did just post in the iOS 3.6.0 thread there is something wrong with the sync too and I can see HR sensor failures almost every night. Like this: [image: 1765188757075-img_5051.png] I am no longer sure if I would go for Suunto device for diving. I always loved Suunto products, compasses, watches but seems like modern software and qa for that is just still in its childhood. This isn’t only a Suunto problem it’s true for other smartwatch, device and even car manufacturers. So I guess we shouldn’t rely on it unless it’s bare analog metal.

@sky-runner Totally agree. I like Coros, but it has been even more obvious with some of the folks they pay to review their watches.

One thing that improved my training plans: setting your pace zones for running in the watch. Go to: settings -> training>intensity zones>advanced zones>Running>pace zones There are some default values that were way faster than my current capabilities. After changing that, the plans got better But I got a question myself: It has rather to do with training theory and not the app I guess. My plan is suggesting interval runs, 5x400m, which is 2km total (I am quite the beginner), with 90s of “trotting” in between. However, the target distance for this training, is 3.2km. Am I supposed to run the 1.2km difference before as a warmup? Or split it up before and after the intervals? Because I won’t make that much distance in the 90-seconds breaks.

@sneike said in Suunto Vertical battery modes: @Brad_Olwin said in Suunto Vertical battery modes: @sneike said in Suunto Vertical battery modes: @Brad_Olwin said in Suunto Vertical battery modes: @sneike The only watch that lets you use maps in Custom mode is the Vertical. There are contradictory information online, are we 100% sure of this? The only one I can enable maps in a custom battery mode is the vertical. Thank you for clarifying that. Do you also confirm that if we start an activity with a custom battery mode and set the GPS accuracy to OK, we can expect the battery life of the Ultra mode as long we don’t keep the map (or the ETA data fields) on the screen all the time? I think if you run maps at all it will impact battery life in Ultra mode. If you save the mode for a specific custom sport profile the battery estimate shown on the watch should be reasonable. I assume you need battery to last 280h?? I used my V1Solar for a fast pack trip in August that was 4d with sleep tracking, OHR, etc enabled and about 12h of GPS per day. My battery estimates in Performance mode ranged from 62h to 90h. I did not charge the watch and had 38% left by the end of the trip. I use Performance unless I need the extra battery and then would use Endurance. Unlikely for me I would need 280h of continuous tracking.

@Fenr1r ?? Not sure what I am saying yes to, but thought a visual of that app would be easier to identify than creating new sport profiles, I like it better than Garmin, They do not have the activity time and HR in the time.

@TED77 luckily I have both Suunto and Polar belts, so I just switched to Suunto and gave Polar to my wife, since she’s an Apple girl and has no problems with H10 that is my solution

@zagazoo Yep [image: 1764871308412-img_3154.jpeg]

@Mff73 only one phone
