Software Update 2.48.16 (2025 November Rain release)

@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.

@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

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.

@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.

@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.

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.

@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.

Dimitrios Kanellopoulos

@HonzaS if you expect to get bettery life savings out of a background on a sleep report its like what we say here in greece -> Squeezing the fat out of a fly to eat.
