@valeR It seems okay with the new firmware. I get 10 days of backup, and generally, I record 6-8 biking activities for 2.5 hours, HR off, just GPS. The biggest issue you can’t customise any of the modes for battery other than in the built-in modes. If you try to modify something, other functions dont work. e.g. I you want to get more battery power, and you go with battery mode ultra and same time you need a map, that option is disabled, and you are forced to be in performance for no reason. I am in tour mode and not bothered much about GPS accuracy, but same time I can’t see the map, which might be important to me. Basically, you can’t customise and save settings the way you want. I escalated this issue with the support team, but they have no clue. Posted here in the forum, but I get a reply from the “FanBoys” without understanding the actual needs of the users. Suunto allowed customising GPS, Battery and other functions with the Ambit model (connect with SuuntoLink), but now that is not supported with new models. I am a long-term Suunto user, and with the newer model, I am getting disappointed more and more. No one is talking about the actual issue with firmware, but be is a race to add some features that don’t work properly or fix issues. More importantly, I am sure no one from Suunto has bothered to read what we are putting up here and suffering with. They put Race 2 now, and no one is talking about the Race S issue, which has been there from day one. They put an advertisement that you can customise a watch, but in reality, nothing works.

@valeR This sounds like two different things. What I saw on my watch was not a safe mode with limited functionality, it reported that it was restoring the watch to a safe state after encountering an error (1403, whatever that means, in my case). It had no functionality other than the progress bar showing the restore progress. No time, etc.

@Steven-Hambleton I bought Barton spring bars that somebody else recommended for Race S. They are a bit thicker and fit perfectly - not loose at all. Also, I compared them to spring bars that came with Suunto nylon band.

@pilleus hi there. Thanks for this. How far back should I go? Or do you know which firmware version I should jump to for the suunto race S. Much appreciated

@ChrisA it is Runalyze… yeah, possibly it’s a me problem

@laufbursche7 I think you should wait - official 26.1 probably will be released tomorrow. I couldn’t stand iP 17 BT issues and installed Beta 4 (not RC) and everything is perfect now. Just as I suspected, battery drain in watch and phone is over - unstable connection was draining watch and phone 24/7. Hope they don’t break something new in the stable release.

I’ve had similar chronic issues with the heart rate on my Race S. Not registering an accurate heart rate until a mile or two into a ride or run, dropping heart rate during an activity, reading overly high during a ride or run. On some activities like cross training, I’ll never get a reasonable heart rate reading. I tried posting a review on Suunto’s website describing this and other issues I’ve had with the Race S and Suunto refused to publish the review saying my feedback “is not a common issue.” I contacted customer support hoping for some resolution since they apparently regard my experience as abnormal. Instead of a resolution, I got a bunch of excuses as to why I can’t really expect the watch to perform any better. All in all, my experience with this watch has been a disaster. I’ll never buy another Suunto product. Going back to Garmin.

@Sixeela29 en tout cas ce n’est pas Suunto qui bloque puisque les segments strava sont une fonctionnalité strava. Je n’utilise pas strava. les infos pour mettre en œuvre sont dans le manuel.

@sartoric actually if I check the activity on the watch, I see HR for the whole run. [image: 1761392386169-img_4023.jpeg]

@Stefano-M64 bummer, doesn’t seem like it’s widespread enough to get attention or maybe people don’t realize it.

This is insane. I remember 9PP had an issue measuring HR when off the wrist, then it was fixed in 2024. And now they are back to square 1. Most likely they could’t reuse any of the OHR sensor code from 9PP due to different hardware and are writing it from scratch making the same mistakes. ‍️

@tailwind_mrs it does start from 0 as soon as you start swimming again.

@rawmtb keep me updated. Hard reset didn’t help for me.

@LGoSo It actually worked! Unbelievable! The low resistance (dirt cheap CooSpo) belt - when combined with all the other measures I’ve taken worked 100%. It’s also changed the heart rate upper level and stabilised it at Zone 4 instead of VO2max - despite today being a minute faster over a 6k run than yesterday when my HR jumped for a sustained period in VO2max (H10+ belt). It’s the first time since I started posting here that anything has made sense. The H10+ strap is simply not working properly - and that appears to include BPM as well as HRV. I did need to shave the part of my torso where the strap goes, dry brush the skin and use a proper conductive gel - but the result is solid. When I had previously tried using the low resistance CooSpo strap with a hairy chest and just water the result was messy. Clearly, individual skin conductivity is involved in determining the limitations of the higher resistant straps. Looks like bad quality control in production - though this probably works for most people.

@fritzbt2013 said in Custom Sports Modes disappearing after each firmware update: @gizmo two updates ago I lost everything like you. Last update (the hotfix) I only lost one custom sport mode. The later has been my typical experience with updates since I got the watch. What I have learned is to add a custom sport mode that I do not use such a stretching and make sure it is the least used. When I get the update that will be the one I lost. I did that as well a couple of times. Now I always have, not a least used custom mode, but a least used standard mode (not customized). And never had any more any mode deleted. Coincidence? Marboutism? Nothing scientific for sure .

@raspy you can see in the app that the % is increasing. I also find the charger very frustrating! Massive improvement with the version 2.
