Suunto 2.50.26 – Q4 2025 Release Notes

@smutnak Bummer. I was hoping this would be fixed.

Александр Даниленко

@Dimitrios-Kanellopoulos I report you bugs every update here in the forum.

I dont see any changes, only downgrades.

About 1-1.5 year ago I even compiled big Word file regarding bugs in the swimming and sent it directly to Suunto via email. No improvements from that time, except a little bit improved stroke detection. In other aspects watches got only downgrades in swimming which I constantly write you here in the forum every update and sometimes directly to support. But Suunto seems just ignore all of that. This is really disappointing.

Out of my extensive testing of one longer walk with a lunch break in between , I can say that the new OHR algorithm on the Race S for me is not a breakthrough.

On the plus side, the algorithm is more consistent in terms of no spikes in each direction. The older algorithm tended to start high, sometimes hit the correct values and even dipped below. Especially as I walk up the stairs in the house where I live the HR recorded usually went down when it certainly should have risen.
With the new algorithm it still does not rise, but it also does not go down.

Now the reading for me is too high all the time. Walking around 105-125. Sitting around, eating lunch 70-90.

For comparison I ran earlier today with an HRM connected and walking down the stairs in the beginning after short exercises for warm up has been 70-90, tieing my shoes at about 60. The OHR showed 120 as I walked down the stairs for the walk…

@Александр-Даниленко If that’s the case, it’s a real shame.

I’m currently at a stage where I’m just swimming for pleasure, without any specific training. But it’s true that when you train seriously, the number of intervals you have to do is quite considerable, and losing the ability to upload workouts to the watch is a real pain.

Александр Даниленко

@enriqueescoms swimming is my main sport. I do about 400-550 km swimming per year with 150-200 hours overall. Watches + HR sensor (which also has problems after certain update on Suunto) are my main instruments.

enriqueescoms

@Александр-Даниленко Yes, of course, I can put myself in your shoes.

@2b2bff time for downgrade your Firmware

2b2bff

@GiPFELKiND why? The newer algorithm is not really worse, just different. And this time Suunto is under complete control…
Tomorrow I know how it behaves on the bicycle during commute…

And I like the other things in the firmware.
I even found an unmentioned fix, that if you go to the options menu as you are about to start an activity and connect an HRM, it will actually start using them right away, visible by the heart with belt symbol. Before it would just show the heart symbol and you would have to go out and back into the activity start to change this…

Thanks for update!

I have a weird issue though on SV1 Ti.

The screen brightness wouldn’t go off during time. The screen keeps to be illuminated and a watch doesn’t go to sleep mode. The soft reset didn’t help.

“Stand by” illumination is off.

I tried to set pass code to force a watch to go to sleep mode but it didn’t help. I did one more soft reset and I was asked to enter pass code but a watch kept illuminating a screen.

Something is off here.

@Dimitrios-Kanellopoulos have you seem somewhat similar while testing?

I’ve just downgraded to the previous software and the screen’s backlight is still constantly on. This update has broken something in my watch.

Egika

@rooldaa have you checked the backlight setting in the control panel?
It is unlikely to impossible that the update “broke” something like this.

rooldaa

@Egika haha, yes, I missed that! I’ve never controlled it for there. Weird that it’s become ON after the update, though.

But thanks for the advice!

@Mads-Hintz-Madsen said in Suunto 2.50.26 – Q4 2025 Release Notes:

Note, that for me on Suunto Race, the installation behaved like a hard reset, i.e., watch needs to be repaired to the app, all zones are reset, sleep tracking is disabled, all paired sensors are removed and HRV range needs to be relearned.

No good for the OP but mine has updated without any fuss

Александр Даниленко

@Egika will this problem be fixed in future updates?

What about other general changes in swimming? Like for example those mentioned here:
https://forum.suunto.com/post/129066
All of them are still actual.

for those, who use external HR sensor in swimming (like Polar Verity Sense), now with new connection watches vibrate, which in swimming happens every stoke. I would like to have possibility to turn of notification of sensor connection. Now to deal with that I have to use “Dont disturb mode” in swimming. Before new connection logic was introduced, it worked fine.

Also, it is almost a year since clockwatch screen in swimming doesn’t show the moment when you stopped, the screen is completely useless. It could be nice if Suunto could return this feature - now S+ app SwimTimer doesn’t replace this, because it always has a delaying when starting counting rest time. That screen could show you the moment when you stoped in the past.

Additionally, I already mentioned it before - drill mode in S+ just doesn’t work. It relies on distance calculation by the watches, which count pools only with hands movements. But drills itself doesn’t suppose hands movement - even in your list of drills in that S+ app you have swimming with kickboard, which means that swimmer hold kickboard with his hands, so they doesn’t move.

I noticed this last night before the release, and it appears it’s still present after the update.

In my watch, I have my birth year correctly set as 1977, but the Suunto app thinks it’s 1976. As far as I can tell, this data is coming from the personal settings in the watch and not something that is set in the app.

Can we expect any changes to to inactivity alert settings? In typical old school Suunto fashion, the setting here is very rigid and without any backbone while the rest of the competition has been doing this for years.

Lorenzo Pintore

Hi all,
I don’t know if it’s just me or a general issue, but with my Race S after the updates the Suunto Plus guides (for interval trainings) are usable only from the default sport modes and not from personalized ones…
Are you experiencing the same issue?

TrailEyes

@atoponce Mine has been showing the exact same thing as yours for a while (like probably a few months). I was born in '77, which was right in the watch but a year off in the app. For the longest time, the app was greyed out and unable for me to edit it there. Now, it looks like I can edit that and correct it to '77, including choosing a specific birthday, not just a birth year.

Dimitrios Kanellopoulos

@Александр-Даниленко Please keep the relevancy to that post.

About the bug with the workout I can its created and marked for the next hotfix probably release (if not q1).

Prenj

It seems now you can update your weight in Suunto app and it gets updated on the watch.

OutdoorMan

I went for a quick 20 min run and the activity got stuck at “Saving” and the watch rebooted itself. It got saved, but this is new.
