Software Update 2.48.16 (2025 November Rain release)

OutdoorMan

I am happy to see that all data from watch is now in sync with the app. Resources, recovery and hrv range now all match. Also when the hrv range changes it is reflected in the app. Very happy about it. But will still keep an eye on it, on resources especially : )

@thanasis this is interesting and I’m observing something similar. After the last update on Tuesday, I noticed big drops (3 or 4 pp) in battery charge hours after finishing a running activity with a HR belt. When I didn’t use the belt, discharge was slower.
I usually wash my HR belt after running and hang it in the shower; I think the watch keeps connecting to it. Last Sunday I wanted to do some yoga with my daughter after my run, and I couldn’t use OHR because the HR belt was still connected. Strange thing, though, the discharge I observed this week happened while the watch was with me at work, and the belt at home.

Regarding the updated morning report: If you have wake up before the alert, you will get the upcoming alert above the weather, letting you turn it off easily… Nice

@thanasis I also noticed that my Garmin HRM Pro+ battery went from 80% to 12% in about a week with minimum usage. I suspect, but don’t know, that my Suunto is connecting to it for hours a time during the day while I am simply at home. Maybe it is connecting while I am in the proximity and draining the battery.
During this period I had used the HRM very little due to the fact when there is a Garmin turned on while using the Garmin HRM Pro+ then the Zone Sense will not work. There cannot be any Garmin or phone connected to a HRM Pro+ (even ANT+) if you want to use it for Zone Sense.

I changed the battery and disconnected the bluetooth from my Suunto to the HRM and it is holding charge. Also to be clear this was before updating to 2.48.16.

@Francesco-Pagano; Same here. My reply below states a similar issue

I got phantom a phantom sensor (which is a Polar Verity Sense I believe) with this update. I can not delete it. When it is selected the menu jumps back to the sensor list. I was able to add the Verity Sense again and the watch uses it. Is there any solution to this or just wait for the next update?

I have it mainly with my stryd. Others report the same thing, also stryd and race s.

I reported it to suunto support. First got an auto reply. Then an auto followup telling me suunto will close the issue if I don’t reply. So I replied.

Then I finally got a human support engineer saying that I should try to delete the ghost entries (which I cannot) or reboot the watch (which doesn’t help) or use the app the delete bluetooth connection (which isn’t an option I cannot find in the ios app) or do a factory reset (which I don’t like to do)

Told the support engineer to keep an I on their forum (provided a link to the topic) and tell the developers to fix bugs.

For me, this behavior came with the firmware update before the last one. Now quite often, my watch will not connect to my polar h9 or stryd. I think it has something to do with the multiple divices bluetooth change.

Yes this nonsense needs to be fixed by implementing either a menu option to delete ALL Bluetooth connections on the watch in one go, or even better, implement the option to delete the orhpaned/ghost connections one by one.
Factory reset is only a workaround and very inconvenient at that!

@Francesco-Pagano I am experiencing lag too. It doesn’t feel smooth

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?

@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)

OutdoorMan

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?

@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.
