Suunto 2.50.26 – Q4 2025 Release Notes
-
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.
-
@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.
-
Not a big deal but on my SV the personnal battery modes setting in exercice option have been reseted to « performances » instead of personnal (I had touchscreen enabled during exercice set on) for at least my personnal cycling mode. I’ll check on other personnal sport modes.

@cosme.costa if you like the bug, don’t report it LOL

9PP owner here…
This thing frustrates me so much. I would just like the watch to function as it did when I purchased it. I have auto updates turned off, but once again the s/w was updated without my consent.
Whilst I understand that ‘expert’ users might appreciate new content, I’ve seen nothing but degradation from every update.
This time I’m getting random vibration alerts (with notifications off), and whilst I was happy with the c1week battery life (I know many others aren’t…), it has now gone flat from full charge in 3 days.
Step counter worked OK when I bought it, but has been broken since an early update. Likewise HRM drops out more frequently than I think it used to.Much of my activity is hill walking, often with a friend who has an ancient Polar Grit which seems much better and more consistent. Maybe time to jump ship.

@duffman19, please check https://forum.suunto.com/post/182890: I’ve already highlighted this bug almost a week ago, but there was (is?) no reaction.
-
@duffman19 Yeah I’m able to reproduce it too but in my SVTS when I return to the main screen the backlight is off it is not turned on after the activity.
I hope Suunto devs polish this bug making it a funcion: raise to wake only in activity as it was already in the S9B or S5P.
-
@Matúš Sorry I didn’t see your discussion above. Indeed this seems to be the same bug. I’m quite certain the trigger is starting an activity. Are you able to reproduce it?
@Dimitrios-Kanellopoulos @pavel.samokha Any news whether Suunto is aware of this?
I saw a few complaints of rapid battery drain on other forums, up to 70% over 24 hours, mainly 9PP users. I’d be willing to bet this is due to an inadvertently activated backlight.

Another wird behaviour since update, observed with both my SV and SRs : in watch mode, I notice while driving my car in moutains/hill terrain, with quick elevation changes, the altimeter is not immediatly responding and altitude is often “stuck” to the value of start of the climb for instance (first I thought that it may have been related to watchface, but I use different ones on each watch, and while going in to the barometer wigdet, the behaviour was the same). It takes few second/minutes so altitude starts updating and it is obviously less reactive than before.
Have you noticed the same ? -

Have you noticed the same ?Yes, I have noticed this. It is also happening in a plane that is climbing from takeoff to cruising altitude. It is an effect during daily mode, not in activity recording.
It is known to Suunto and checked again.During activity, the altitude change filter is adaptive: für alpine skiing with quick elevation changes, the altitude is updated instantly. During hiking there is a filter in place that only allows slower altitude changes.
-
@duffman19, I confirm you that the trigger is the activity starting, actually, the activity starting screen (where are listed the activity settings). Triggered the bug by scrolling the settings, the raise to wake starts to “work”; later, by leaving that page, the back light stays on no matter what until a setting related to the screen in manually triggered.
I reproduced the bug two days straight: the triggering behaviour and the consequences were always the same.
-
After the update the sleep tracking continues to work well but the morning report disappeared. How do I bring it back?
-
@Highlands, try throubleshooting as described in this thread (read all the messages, not just the short three point guide).

With previous firmwares I had a problem of altitude drifting in watch mode. Altitude would slowly go up during a day by 30-80 m. In activity, altitude was spot on. But after updating my Race 1 with this FW, the altitude is now drifting down in watch mode. I guess they did something with the fusedalti algorithm, but it needs some more fine-tuning.
-
During the hike I had the past Sunday there was a LOT of wind, nevertheless my Race recorded no odd altitude spikes, giving correct total ascent/descent values, in line with the ones I got with the app (Oruxmaps) on my smartphone. So it seems the new “SMART” barometric algorithm is actually doing what it is supposed to do
-
@Stefano-M64 Thanks for the info. Great news. I still haven’t had a good chance to test it out
-
Serious bug not being able to see manual laps in the app from activities after the last update. Still able to see them in my race s after the sessions but not in the app. Hope they solve this quick since it’s a very important function.
-
@elis001 it’s a bug in Suunto App. it’s fixed in version 3.7.1 (at least on iOS)
-
Sorry for this question, maybe it was already addressed. If I am understanding this correctly, ZoneSense is now turned on by default in every sport mode and it gathers data as before. But you can only see that data in app after the activity is done and saved. And it does that even if it’s not turned on in SuuntoPlus section.
But if you turn ZoneSense on in SuuntoPlus, you can view data live on separate screen, and data is also gathered. And it’s basically the same as before the latest q4 update.
So that means that if you do not turn ZoneSense on, it still gathers data that you can view after your activity, but you get two Suunto Plus slots. And the trade-off is that you can’t view ZoneSense data live during activity.
I hope this makes sense

You can if you choose Exercise options > Intensity zones > ZoneSense
