Software Update 2.48.16 (2025 November Rain release)
-
With this update, battery consumption has almost doubled, while manual SpO₂ measurement has been restricted or effectively disabled.
In short, this was a poorly executed update.
Suunto needs to stop allowing software decisions to undermine the hardware excellence and engineering effort that clearly exists in these devices.
At this point, it feels as though Suunto is actively working against its own loyal customers.
Updates like this do not improve trust — they destroy customer loyalty.
A flagship device should not lose functionality, efficiency, and reliability with software updates.
If this direction continues, Suunto risks turning strong engineering achievements into wasted potential due to software mismanagement.

@OutdoorMan
well … as they do for the app
-
I can’t tell from all the negative comments here if it affects a large or just a small portion of users. My watch works perfectly fine.

@BastMaSVSRS9PP Mine also works great. I have definitely had issues in the past and eventually they get fixed.
I love this forum and think it is the best of the big three (Garmin, Suunto and Coros). I know people are upset and as we bring more and more people into the family that are unfamiliar with Suunto this is going to be one of our growing pains. Reddit is a cesspool of “why should I buy a ____” or “I come from Garmin and this is what Suunto should do” posts. For the most part, this forum is for people who love the brand and love the tech. It is an amazing place to celebrate Suunto and how far it has come.
I will say though, I am getting battery drain complain fatigue. I do not discount the sadness it must bring the people it has affected, but I am not sure what countless posts are going to do to solve this problem. If you look up my profile I have also had numerous complaints and I should have been better about reporting that they are fixed when they were.
I am in a very lucky position to be able to try out Garmin’s and very steep discounts and I will say, for all the complaints I hear on here, the Vertical 2 and Race 2 are so much better to use day to day than the new Fenix 8 Pro 51mm. For a watch that isn’t really an upgrade, but rather just a watch with LTE and inReach added, it is buggy, slow and many of the "wonder metrics like Body Battery and Sleep Tracking were less than good. I guess what I am saying is that Suunto has a good product line and they are working through some things, but at the end of the day I feel confident that they will release bug fixes that work soon. Most of us are not doing Ultras in the Winter so while we shouldn’t have to charge super often, it will be okay until spring when we all need the tech to work. (and it seems to be for a majority of people)
Suunto Vertical, Vertical 2, Race, Race 2, Race S and Run. Back to the Race S at the moment.

@Stavrogin well said sir! Can’t agree more
-
Also no issues. I think people with issues are inclined to keep repeating them, as if saying they have an issue again and again will make it go away.
Vertical 2 is a brilliant watch. Just back from circumnavigation if Lanzarote. First multi day use of the watch and it was spot on. Maps super smooth and easy to follow.
The only irritating thing I had was how bright the display is when walking in the dark… Should have changed to dark maps.

As the sole moderator of r/Suunto, I’m interested in feedback on what I can do to make it a better place for Redditors.

@atoponce I think you cannot make people to use their brain. I used to read reddit posts on Suunto and Coros subreddits, but sometimes they ask questions which could be answered by 1 minute of googling. It’s mind blowing sometimes when someone cannot decide on basic things and instead of investing a bit of time he just plainly asks and is waiting for random people to decide on his behalf. This is why I don’t visit reddit anymore.
-
@atoponce if you compare r/Suunto and r/Garmin, I think Suunto is a bit quieter but the better of the two. I think it is quite good as it is. However, a lot of posts do fit better in the forum or are duplicates of things asked or talk about here… a simple search would help a lot of times…
Also, I don’t get why people downvote others that are telling facts, only because they dislike what they hear? That seems to be a very common theme on Reddit…
-
@BastMaSVSRS9PP What software version are you currently using, and are you able to perform manual SpO₂ measurements via the widget on firmware version 2.48.16?
Because Suunto representatives have stated that this is no longer possible, claiming it was removed for battery optimization and to provide more reliable dat -
@AYHAN-YILDIZ thats a misinformation. I have a Vertical 2 and checked it at the Moment running the last Firmware. O2 measurement manually works as expected.
-
I think this has already been discussed, I don’t know if here or somewhere else, but I can’t find it.
In any case, I’m reporting this bug for pool swimming:
The interval timer isn’t working.
(I missed this information while swimming last night)

i suppose it depends on whether your motivation is to have a better watch, or feel better about your purchase.
personally i welcome the moaning. public complaints are the only bargaining chip users have (beyond returning the watch), and where better to do it than *.suunto.com!

it has a pretty bad AI bot problem. eg https://www.reddit.com/r/Suunto/comments/1e16g5d/use_of_botsllmsuunto_sales_folk_in_the_comments/
they also give bad troubleshooting advice. it’s pretty easy to spot them.
