Software Update 2.48.16 (2025 November Rain release)
-
@Stefan-Kersting I‘m not sure if this is helpful?
https://forum.suunto.com/post/159180
The firmware versions for SV are really old… and I never did a downgrade…
I think that 2.43.12 would be useful for you, but I didn’t find a link there. -
@Stefan-Kersting I have done factory reset on my vertical twice including when it was sent back to suunto repair shop in Australia and it did not solve my battery drain issue. To the others saying it will take a few days to see if the battery drain is fixed would not apply to me. Mine often drains at 1% per hour on a bad day and about 1% per 2 hours on a good day. I will know within a few hours whether the battery drain is fixed once this update is available to those of us in Australia
-

some custom sports mode disappear with this update ! -
@Antoine all of them, in my case. I am not a happy athlete.
-
Update went smoothly, HR zones and custom sports intact.
Morning report looks good too but the Moderate /Good etc label under the sleep percentage s missing?
Reading the above, Suunto really needs to work on software that backs up the watch to the app or the cloud, so if a reset is needed, or an update goes awry, you can choose which data to restore such as HR zones, logbook, Bluetooth connections or sports modes.
-
Update wiped out pace zones. All else seems intact with race s.
-
On my Vertical 2 custom activity kept fine after upgrade. However, battery draining just as bad as before
Down from 50% to 42% in 14 hours including the update (about 2%) and a 45 minute GPS activity (1%) with 247 HRM, AOD and full night tracking on. Really disappointed. -
Battery drain is NOT fixed @Dimitrios-Kanellopoulos @pavel.samokha
Lost 5 % of battery power within 12 hours. Dropped from 96 % on Monday 6 pm to 91 % on Tuesday 6 am.
That’s not good enough!!!
-
@Gideon-Kaempfer you are not the only one. The same here with my V1. Had this issues now to month and suunto can’t fix it
-
@Stefan-Kersting since 4.11 i lost 6% per 24h every day. I updated 12h ago and already lost 6%. Looks like battery drain doubled. But still i hope battery update process maybe accelerated it. Will see in few days.
-
Morning report now is nicer grouped together and it has a weather forecast on top. Like someone at Suunto is reading in the forum…

-
@Tomas5 it’s not acceptable to have so much battery loss. Do you really have to wait several days to find out of it? I know the answer already now
-
Only 1% lost during the night sleeping, battery seems fine on my race 2, new morning report looks good
Did not loose any custom sport mode or zone settings but damn when I read some of you I emphasis your angryness
-
@Josaiplu sleep was measured but i didn’t saw any report at morning. Old one was hard to miss, is this new report disapearing by itself in few minutes?
-
@Tomas5 Nop it behave the same as the old one but with a new look, météo at the top and new graphs for sleep phases
-
@Stefan-Kersting i have still hope cause i played with manual blood oxygen measurements to see if it works so i have still hope. If not, i will rollback again. I did it with last update so i hope i will be able to do it with dis one too. For now firmware i got with watch was only one good. Since then battery issues and blood oxygen issues. At least with this one blood oxygen works manually but night measurement was 83%, didn’t see that low value since i rollbacked to original firmware until yesterday update:D
-
@Josaiplu what is the point with introducing new fancy things when they can’t fix basic bugs
-
@Stefan-Kersting I think they try I did not have any issue since I got my race 2 except battery drain, I did rollback and now it seems fixed
It’s hard to bring new features without bugs in software’s development, they miss something like open beta maybe to allow users to test new features and report while the others remain in stable branch released after everything is fixed -
@pavel.samokha I did a factory reset on my SV2 (paired with a new phone) and after sleep tracking and morning notification, the battery dropped from 100% to 98% and the problem with the middle button not responding after waking up by raising my hand also disappeared. So I’m satisfied (so far).
-
@Stefan-Kersting There are not really fancy new features in this update, only the merge of the two software streams and bug fixes.
So I guess they focused on the bugs this time. But as it seems unfortunately with limited sucess
