Suunto 2.50.26 – Q4 2025 Release Notes

[cosme.costa]

@Egika As @enriqueescoms I have noticed something similar. I use a Coros HRM armband most of the times (when I want to use Zonesense I use Suunto’s Smart belt). The thing is that the Coros HRM do not have a switch so, it turns on with the contact of the skin or when a device connects to it but in the first case if you put it on but and after a while it is not connected to a device it swithces off to save battery.

With the previous firmwares when the watch looked for sensors it turned on the sensor and connected to it and everything very fast, with the version 2.50.26 it turns the sensor on but does not connect to it, the watch says that the Coros sensor is found but doesn’t connect to it, the watch OHR is working instead and the HR symbol in the watch is without the straps, so I need to go back in the screen and enter again to the sport mode to use the external HR. Moreover with the previous firmaware the sensor connection was 1/2 seconds and now is 4/5 seconds.

I will disconnect and recconect the sensors again to see if it helps.

This is realted to MIP watches and one thing that I have noticed in my SVTS.

I have noticed that my watch turns the screen light turning the wirst during the activity At first I thought it was a bug, so I did a soft reset but it still works and it’s quite clever as it only works at dark hours (I have tested it with running and trail running custom sport modes). It is not listed as an improvement or new feature. Can any tester confirm this? Can someone explain what it triggers it?

If it is a bug DO NOT SOLVE IT, at max add the option to turn it on and off.

@cosme.costa hi! This has been there as far as I can remember. But the light is to low especially now during winter in Sweden.
I have set light to turn on with guester mode on but it is to low for using outside on sunny day in the forest where it is shadows. Even if I set it to high it only turn on verry low? I do not understand his. The only way to see is to hit a button but then it turns to another page.
This behaviour is when I have an activity on.

[cosme.costa]

@helgonet12 No, the wirst light ONLY in activity wasn’t there for sure, was removed in the last firmware of the S9B. I’ve been requesting it for for some time now: light with wirst movement only in activity . Around 60% or more of my yearly running/trail running is done in the dark with a headlamp, so have pretty clear how it worked till now.
What you could/can do with previouses firmwares is that you activate the light with wirst movement always, in and out of the activity, there wasn’t any difference.

@cosme.costa Are you saying you have raise to wake turned OFF in general settings, but it activates during activities? Is this all the time, or only after sunset, or only when it’s dark (as detected by light sensor)?

I just tested and my SV1 does not do this, although I am with you and would like to see this as an option.

[helgonet12]

@cosme.costa Ok, maybe i remember it wrong. anyhow the raise to wake is something I also would like to work better than it does now. It should be possible to set the light intensity for sportmodes only as well. regardless of if it is turned of or not under general setings

@sky-runner known an on full prio. workarround is to enable intervals screen on the custom sport mode

[aiv4r]

I have just noticed, that while using built-in watch intervals(not the guides from the app), one cannot end the interval by pressing the LAP button anymore. Is that on purpose or is it a bug?

[cosme.costa]

@duffman19 Exactly this. From my findings it only works after sunset. I have done 1 run and 3 trail runs since the last update. Just after the upgrade I did a late trail run with light, then a trail run after lunch so no light, then a run that was early in the morning, at dawn and it worked til it was shynny enough any yesterday a trail run with headlamp that was working with light, I even show it to my son that was running with me.

I tried to reproduce it in the office but it do not light up, I do not know if it is because of the time of the day or because there is to much light.

Anyway, If it is a bug I love the bug.

[duffman19]

@cosme.costa Interesting. I’ll test again after sunset.

[GiPFELKiND]

@Dimitrios-Kanellopoulos and pleased enable suunto guides again in Custom Sports mode! They are gone there and can only be selected in Basic Sport modes.

[sky-runner]

@Dimitrios-Kanellopoulos Thanks for acknowledging! Adding an interval screen isn’t an acceptable workaround considering the max of 3 data screens. Some of us need to use data screens with a small number of fields, so my custom sport modes already use the max number of data screens.

@Tieutieu Hello, this past Sunday in a trail race (25km) I experienced firsthand the issue of adding reference points and REMOVING specific information about those climbs or descents that run between them.
For the time being, while Suunto works on this major issue with the Climb, I’m considering adding more information points at the summit, descent, and next aid station checkpoints. It’s a cumbersome plan or solution, but it could solve my problem of using the zoom to its maximum.

[Tieutieu]

@Elmiuel Hi ! Thanks for sharing. I won’t do that myself ; too much complicated to handle, and no indication of average slope remaining to waypoint, distance on climb…all that is visible with standard guidance screens without waypoints.
I hope it will change again to have this zoom level that we had before when there is waypoints.

[cosme.costa]

@duffman19 definitely it’s a bug, I have reproduced the behaviour with my trail running configuration, getting GPS signal not indoors, then I switched to running and couldn’t, and then to trail running again and it didn’t work.

Unlucky me . I will try to record a video if I’m able to reproduce it again

[duffman19]

@cosme.costa Holy weirdness, I was just able to reproduce this behavior on both my SV1 and 9PP. I just tried switching back and forth between different activity start screens and, randomly, the raise-to-wake backlight would activate. It didn’t seem to depend on which activity (sometimes walk, sometimes run, etc.) and it didn’t activate every time. But when it did, it remained active even after starting the activity.

However, I also noticed that once I returned to the main watch face, the backlight remained ON as if I had activated in the settings (which it wasn’t). Even after interacting with the watch and then letting the watch face time out (after 1 minute), the backlight remained on. The only way to turn the backlight off was to go into settings, toggle it on, and then back off again.

@Dimitrios-Kanellopoulos This seems like a pretty big bug that will cause significant battery drain if users do not notice that the backlight has been inadvertently turned on.

To reproduce on SV1 and 9PP:

• Turn off all backlight settings (Standby: Off, Raise to wake: off).
• Select a random activity to bring up the start screen.
• Wait for backlight to timeout (~8 sec. after no interaction).
• Test raise-to-wake with wrist flick.
• If it does not activate, try a different activity until it does (it will eventually)
• Return to watch face
• Backlight will now remain ON in standby mode

I’ve been able to reproduce this every time I’ve tried.

Race2, “Raise to wake” strange behaviours during activities:

I’m using Race2 with Rase to wake ON, same configuration than Race S. Many times during activity the screen remains ON even when my arm is down, for minutes at a time. Maybe half duration of the activity the screen it’s been on, so battery drain is higher than usual. For comparison, Race S, same time in right hand, goes off immediately after arm is down.

[duffman19]

@jjpaz I’d guess it’s all related. Something about starting an activity is altering the backlight settings for sure.

Are you able to reproduce it on your Race S through the steps I listed above? Try starting a few random activities (or just going to the start screens) and see if anything changes. It doesn’t happen every time for me, maybe about half the time.
