Software Update 2.48.16 (2025 November Rain release)

[Stefan Kersting]

@ChrisA I don’t really know but I have a vertical 1 og there are many users with the battery 🪫 issue

[Ecki D.]

@VoiGAS Yes and please too for Autostop and Autolap every update they are back to default.

[Gideon Kaempfer]

@ChrisA for me the battery drain issue is for a Vertical 2…

[Kaiphi]

Update has been successfully installed on the Vertical 1. I think even without loss of a personalized sport mode. Sleep report when waking up in the new design. If I open it again, it will be in the old one. Had no battery problems before and not now. Just 2 hours on the bike with 1.3% per hour consumption with best gps.

I’m currently get phantom vibration on my race 2, only suunto belt paired (fresh post update)
Watch vibrate without nothing displayed at all post activity
If I open the activity pre start page I see the belt already connected
I will soft reset and it will disappear but bug still here
The disconnect issue I suffer last time was gone after doing unpair/pair of the belt
I assume that battery drain can be caused by such behavior if the watch continue to look for BT devices after an exercice it is quite energy consuming

Thx for the Info

@ChrisA Yes, it is the Race I. The last update prior this one mess up the life battery. What I think is that the connection to multiple heart rate devices just have something to do with it. I expected that this update solved the issue but now it is even worst. Before these two updates I had to charge my device after 5 to 6 days depenging on my weekly training but now it is not even two days. I do not even have the notifications on. I came back to Suunto after the horrible experience with the Spartan series and I do not think I will repeat again with this brand.

[Stefan Kersting]

@Josaiplu I had the same problem too and reported it. But nothing was done with it. Think too that it’s part of the battery drain problem

[Miguel Angel Moreno]

@Josaiplu I am facing the same issue here. Everything is working fine if I use the Coros one, but with the Suunto HR belt it looses the connection multiple time in my last two work outs. I am not even sure that zone sense metrics are accurate after this update but unfortunately this is something that I cannot verify.

[Dimitrios Kanellopoulos]

@Stefan-Kersting afaik it wasn’t

[Dimitrios Kanellopoulos]

@Josaiplu is the sensor on the belt ?

[Josaiplu]

@Dimitrios-Kanellopoulos yes, I have then removed it and still get one vibration, I then go to the activity start menu and see my hr with the icon without the belt. I assume that the last vibration was related to the disconnection of the belt caused by removing the sensor of the belt

I have now done a soft reset and no more vibration

[pilleus]

No problems with the Bluetooth connection of two heart rate sensors and my Vertical. Two activities with more than two hours, Polar Verity Sense connected during the first activity, Huawei Fit 4 Pro connected during the second one.

No disconnection, no false values, everything was fine.

[ChrisA]

@Miguel-Angel-Moreno ah I see, thanks for the clarification. It seems to affect only some devices though. My Race I shows no signs of battery drain, but very annoying for those who have devices that drain ones battery that fast

[gone troppo]

Does anyone actually know what suunto has done to address the battery drain other than saying it’s fixed? Mine hasn’t changed one bit still draining approx 1% every 2 hours best case scenario.

I see it has been mentioned to let the battery drain and recharge before making final judgement I will do this however I’m 99.9% sure this does not make a single difference as I have already done that many times with no change. Why would it all of a sudden make this watch start working as it should? Doesn’t seem logical to me.

[Stavrogin]

@false The same can be said for their fixing sleep tracking for those of us that sleep tracking does not work with. I see the generic “fixed sleep tracking” in so many previous updates, but the song remains the same.

[Tsubasa]

I have SV2 2.48.16 and have the same problem about Blood Oxygen. The day before yesterday I updated firmware and it was able to measure manually. Also it could measure well while sleeping. But today SpO2 indicates 90% during sleeping. And I can’t measure SpO2 manually again. I tried many times but keeping silence. I redid firmware update “2.48.16.26426” from the debug menu. Currently, SpO2 measuring seems to work well. But I think it will crash again in 2 days.

@thailon said in Software Update 2.48.16 (2025 November Rain release):

New improved morning report is missing Fell asleep and Wake up time? Why?

That New sleep report also doesn’t tell overall quality of night anymore (excellent/good/moderate…).
We have to go back afterwards to sleep widget to have it displayed. Didn’t noticed first, but it was one of the things that my wife was looking at, she noticed immediately (S9pp)

About my Race S, for now battery consumption is very high after update, I wait for first full battery cycle but for now it’s not good (no notifications, display to low, raise to wake, dnd at night, sleep tracking, hrv on, spo2 off). Almost no exercices done since update.
Fully charged two days ago…44% left 48h later.

[HonzaS]

@Tieutieu On Vertical 2, there is also no black background in the morning report. It’s lightening a little bit, and that´s not necessary IMHO and could save some battery life.
