Software Update 2.48.16 (2025 November Rain release)

Gideon Kaempfer

Battery update for Vertical 2:
10% battery drop in 24 hours including (!!!) 2:43h of GPS exercise (two bike commutes and one run all with OHR). Activities normally take about 2%/hour so I would say this mode represents about 6% per day without activities (16 days?).

With the following settings:
AOD on
Raise to wake off (!) - I see the time dimmed a bit but full data only upon button press (Athletic watch face)
Notifications on (occasional email, WhatsApp, Slack…)
Wireless off
BT discovery off
No BT devices except app (Android 6.4.7)
Brightness low (not sure if it matters)
247 HRM on
Sleep mode on (22:00-5:40) with HRV without spo2 and auto DND (display off)
Firmware 2.48.16 (latest release)

This is a significant improvement over Raise to wake set to display only which was at about 9-10% per day without activities.

I’m still testing but if this is true, it seems to me that Suunto should implement a very-low brightness mode with raise to wake only lighting up the full watch face as dimly as the AOD.

I ran a few tests on my SV1. First thing: battery calibration.

I charged the battery to 100%, then left it plugged in for 60 minutes.

I started an activity to drain the battery as quickly as possible: with two SuuntoPlus apps, the map displayed, and automatic lap every 10 seconds. Brightness set to ‘Low’. The battery manager reported: 25 hours of battery life, it drained to 100% in about 32 hours.

Then I reconnected the watch until it was back to 100%, left it plugged in for another hour, and then did a soft reset.

That was the battery calibration.

Since then, I’ve gone running for 3 hours with the map in performance mode: I estimate the battery life in this mode to be around 60/65 hours based on the results of the run. So pretty close to the value advertised by Suunto. However, in daily use, I still get between 6/7% battery life per day without any activity. This leads me to believe that the battery is good when in use, but in ‘daily’ mode it’s really not great.

In addition, I also noticed that my heart rate monitor ran out of power very quickly during the summer: in one month, the batteries were dead.

I believe that is related somehow to the problem… something is running on the background with the BT connection

automatic rotations every 10 seconds

What does it mean?

GuillaumeA

@pilleus automatic lap every 10 seconds* (sorry english is not my main language so I used Deepl )

That’s exactly my point, all my tests since the last updates goes at the same conclusion than you.
The battery drain in Vertical 1 is operating outside activities.

I really I think I did everthing from the book to stop the drain on the Vertical 2. I thought for almost a week Suunto finally solved it. But the last 24 h has been bad. Even after 3 soft resets, which normally did the trick.

Today is the last day to send the watch back, but I can’t make that (and I don’t want to loose the watch. I like it too much.

I sent two times (last week and today) a battery log to Suunto. Do they respond to that?

It seems the drain occurs after activities. Not always. Just sometimes. It might be the Heart Rate Monitor, but still not always. Not sure if it ever occured without using the HR-monitor (H10)

Just a question: is there a plan to release an additional SW update in Q4?

@maszop no q4 , just bugfix

OutdoorMan

@Tieutieu I know, but does it mean “there will be no Q4 update” or “no, this is just a hotfix, Q4 will come later” ? : )

Exactly, I understood that 2.48.16 is not Q4.

And the question to that answer was:

Is this a Q4 update or just an additional bugfixes update?

isazi

@Squirrel I thought it was Q4

Well, if not Q4, then there’s quite some new features coming in Q4 that I thought were reserved for Q1 2026. Let’s see.

@isazi sounds promising

@pavel.samokha said in Software Update 2.48.16 (2025 November Rain release):

New features:

Ground contact time and vertical oscillation in running log summary

Can somebody answer me the question why the new feature (ground contact time and vertical oscillation) is only available for the newer (2) watches? Missing Hardware (which one?), processor speed or just software?

This question is not answered yet. Is somebody able to say something to this topic?

@Francesco-Pagano I did several soft resets over the weekend to sort a different issue & noticed the same behaviour afterwards, a lag when scrolling up into sportsmodes.

A few times the sports mode “shapes” were presented but with no icon or writing inside, I had to scroll back down & back up before they populated correctly.

No issue today though & scrolling fluidly again.

@Mitch9 it is only available for the two new models, R2 and V2

@Horizontal_2 i have after 3 days 80% thats 6.7% per day.
AOD off
Raise to wake (display only)
Low brightness
24/7 hr tracking + sleep tracking with blood oxygen and hrv
Phone notifications

So Race 2 will do around 15days which is less as (up to) 18days advertised. But still good battery life. Not doing sport lately so i can’t tell about GPS consumption yet.

I know but I’m interested in the reason.

@Mitch9
hardware … or because it is what it is

@Tomas5
Thanks. I have about the same.

3 days 79%. (started from 99%)
AOD off
Raise to Wake or DND
Low brightness
Same sleeptracking
No notifications
It includes 1 h 50 min of running with map and HR-belt

The weird thing is: before the run (yellow) it’s better than after (green).
