Software Update 2.48.16 (2025 November Rain release)

[Brad_Olwin]

@Stefan-Kersting depends on which firmware, the prior one had issues with battery drain. Not sure that will rid you of the ghost connections but it won’t delete all of the sport modes, etc. Similar to an update, then you could update.

@Brad_Olwin when I am reading this post I am not sure if a factory reset will solve the problem…?

@Stefan-Kersting You’re asking if a factory reset works to remove ghost BT connections? I did it with the previous update because I didn’t want to wait for another update and, yes, for me ghost BT connections disappeared. Unfortunately, as you know, you have to reconfigure everything afterward.
Before performing a factory reset, I tried reverting to the previous firmware version. Surprisingly, the connections that were previously known also became ghost BT connections.

[Stefan Kersting]

@fondueaufromage all right then it looks like that the factory reset is the way to go. Just wondering if - when not doing the factory reset - the ghost BT connections are responsible for the battery drain

@Stefan-Kersting 2.44.46 (August 25) was the version which I used in summer… battery drain was ok, but installing this firmware crashed my individual sport modes like a hard reset… 2.44.52 (September 25) had a little bit more battery drain… and the ghosts in your case? Before, we had 2.43.12 (June 25) I think it was good, but no map download without charger? The choice is not easy I think

[Stefan Kersting]

@SuperFlo75 I have just the two pkg you see on the foto. 2.44.52 doesn t work because of both battery drain and the ghost BT. And thers no chance to go back to 2.44.46 when this pkg is not on my watch any more

[fondueaufromage]

@Stefan-Kersting In my case, I can’t say whether battery consumption is worse after a factory reset or if it was due to ghots BT connections. But I don’t want to generalize; this is just what I’ve observed with my SV. Perhaps others will have different opinions.

Before performing a factory reset, you can start by reverting to the previous version and see what happens to the ghost BT connections. My idea was to revert to the old version, delete the known BT devices, and install the new one, but that didn’t work. That’s why I ended up doing a factory reset, and I’m referring to the previous update 2.44.52 (2025 Q3 - HOTFIX). Now, with this new update, everything went well.

@Stefan-Kersting I‘m not sure if this is helpful?

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 !

[mickywickyftw]

@Antoine all of them, in my case. I am not a happy athlete.

[Steven Hambleton]

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.

[Stavrogin]

Update wiped out pace zones. All else seems intact with race s.

[Gideon Kaempfer]

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.

[Stefan Kersting]

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!!!

[Stefan Kersting]

@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

[Tomas5]

@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.

[2b2bff]

Morning report now is nicer grouped together and it has a weather forecast on top. Like someone at Suunto is reading in the forum…

[Stefan Kersting]

@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

[Josaiplu]

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
