Software Update 2.48.16 (2025 November Rain release)
-
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.

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.
-
@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.

Honestly, I see a lot of people freaking out about battery life… but trust me, you’ll only care about it for one week. After that? Zero thoughts given. You’ll be too busy checking your pace, cursing hills, and pretending you’re not dying to worry about whether your watch has 37% or 82%.
And let’s be real: a week-plus of battery is more than enough. Charging a watch is like brushing your teeth—takes a minute, doesn’t ruin your life, and arguably prevents bigger problems.
So yeah, don’t stress. You’ll forget about battery life faster than you forget your warm-up.

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.
Suunto has done changes in the firmware. In the version before, the watches did not under all circumstances disconnect BT sensors properly. With 2.48.16 some cases for this have been fixed and thus, the BT connection should not draw excess energy.
-
@Kraisun-Tunta my words.
-
@Kaiphi
yep, I’m getting these ghost vibrations randomly during the day also.
i have sync with phone turned off, no activities recorder, just standing there, preparing food and watch buzzes like crazy - few times in a row -
@mich-heller soft reset solve the issue for me, I guess until I redo a training session with a BT sensors attached maybe, but for now they are gone
-
@Kraisun-Tunta I’m learning that making your own conclusions on what users care about doesn’t bring great products. If users say they care about battery life, most probably it’s something to consider. For me it’s the most important thing for my electronic devices. You may see it differently, but that’s why different products or features target different user groups.

I have to report that for the first time ever, my 9PP went from 58% battery Wednesday at 10:30pm to 9% battery Thursday at 06:45am… an almost 50% drop just overnight. Installed 2.48.16 the day before. Of course, I immediately downgraded to 2.44.52.
You know guys, I feel Suunto is showing me the door out of the brand by burning the bridge ahead of us with the disappointment the Vertical 2 is, and by buring the bridge behind me by making these strange updates. Just my 2cts. -
@ChrisA My Vertical 1 suffers from battery drain, it’s NOT during activities. I 'm waiting a full battery cycle to confirm if the drain is fixed by this update (but I am not optimistic for the moment).
-
@fv4500 Once Apple cranks their watches battery life up to a week, I’m gone. And so many more. The biggest pro for me would be music streaming, navigation and ability to make my own AW apps. Yeah, it’ll be a hard time for all the smaller brands. Everything what we are here for is battery life. If Suunto cannot deliver that, there is no point in their proposition.

@cheetah694
Maybe you are here for battery life - but please don’t make it a “we”
I am not here for battery life. My watches last for more than a week without me counting percentage steps.
I am here for a sports dedicated light weight watch that has style and a great training ecosystem. Plus navigation during the big and small adventures. in the outdoors
-
@Egika well said! And not everyone has these issues. My watch works perfectly fine
-
@Egika There is Sports Tracker already. So switching to AW will be a no-brainer once the time comes. And so many more apps, it’s an open platform. The truth is, Suunto needs to prioritize code quality over everything else. The app telling me I need over 200 hours recovery time is not great training ecosystem (reported by dozens, goes unfixed for weeks). The app telling me I slept 4 hours and have 20% resources over while I myself am feeling snappy and 9/10 is not great training ecosystem. Etc. etc. It’s bearable to live with, not more than that. Just a reality check.
-
@Egika same here! I tried all major brand and Suunto suits my needs best. Besides one Suunto Race, which had a defective HR Sensor out of the box I never had major issues in the last 5 years. I can fully understand that it’s annoying if a working device starts to have issues due to an update like @Stefan-Kersting has with its Vertical though! That should not happen and fixed asap.
