Software Update 2.48.16 (2025 November Rain release)
-
@Horizontal_2 said in Software Update 2.48.16 (2025 November Rain release):
The weird thing is: before the run (yellow) it’s better than after (green).
I think that’s normal, not weird. Activities consume more energy than the watch state.
If you mean the steepness of the curve, when I look at it and extend the green line, it starts at the same point as the yellow line, at 100%. This implies that the trend also includes activity consumption. If this were correct, the green line should reach 100% in -days. -
A week after having updated and a then recharged from about 50% to 100%, I have now ≤ 5% per day on my Race, with the following settings and no acticities:
AOD off
Raise to wake (display only)
Medium brightness
24/7 HR tracking + sleep tracking and HRV (without blood oxygen)
Notifications -
@segi_pn The moment the line leaves the yellow line and jumps the green line is the acitivity. The rest is without activity. Doing one activity shouldn’t interfere with the rest of the battery performances. That would be incorrect. It should have a steepness of 5%/day
In a few days I’ll give an update

How can we have the Ground contact time and vertical oscillation ?
I did several run activities since the update but nothing is shown in the move report…A3S | S9B | S9P | S9PP | SV1 Ti | SV2 Ti
Suunto Wing
Suunto App: Android Beta -
@v.sacre It’s automatic for running activities (running,trail I have not tested others) and with custom sport mode based on these activities
You also have new data fields related to these metrics that I did not use as I only look to my GCT after my workouts in the app -
@cheetah694 how’s that possible? I’m on Vertical 1 and I do not have such info. It was the first (and quality) I have had checked before. I have to go to sleep widget now
-
@thailon I think it’s only available on Run 2 and Vertical 2 without attaching external devices (e.g Stryd)
-
I am on Vertical 2. And It tried yesterday without Stryd, but still it don’t show those metrics.
-
@v.sacre did you check the detailed stats in your app? Under technique I see Avg. ground contact time and Avg. vertical oscillation.
-
@Gideon-Kaempfer nothing under Technic section…
-
@v.sacre maybe it was too cold
just joking. I just used the default basic running activity without any special settings on 2.48.16 firmware on the V2. -
@Gideon-Kaempfer Yes I did the same.
But maybe it is because I have a stryd connection? Even if for this specific activity, I was not wearing the Stryd… -
@v.sacre I can confirm that it is there (on Race 2). What model do you have?
-
@Horizontal_2
Yes, I understand what you’re saying. The thing is, when I put a ruler on it, I can see that the green trend line starts at the same point as the yellow one. From this, I conclude that activity was also included in the battery balance calculation.
It is quite questionable how to calculate the energy balance in batteries. The problem is that it depends on consumption. Higher performance requirements reduce the possibility of effectively utilizing the amount of energy in the battery.
If you calculate the battery capacity at low consumption, you will get a higher capacity than at higher consumption. That is, if the consumption is X and the battery runtime is Y, then if the consumption is 2*X, the runtime will be less than Y/2.
This is a problem of the battery’s internal resistance. The higher the current, the greater the internal energy consumption of the battery.It seems to me that Suunto tries to take into account how the user uses the battery when calculating the battery status so that the estimates are not too optimistic.
I am curious to see the continuation of your measurements

@segi_pn Actually I doubt that Suunto do any predictive calculation based on user profile usage. IMHO they just measure normal % based on some battery voltage graph they have stored on the watch. When you do an exercise they transform the % into hours left based on their datasheet (e.g. if 65h in multi-freq GPS is the spec and you have 50% left, they will say 32h left). However, when you finish the activity (higher consumption) the normal % will immediately be shown to be lower (I think based on the battery voltage). This doesn’t explain the change in the graph trend which seems like a bug to me (e.g. maybe the BT remains connected to some device after the activity or maybe syncing to the app got stuck).
-
@segi_pn Thanks for the picture. It made me smile. I appreciate your time.
I think it’s a coincidence. During the green line I had the watch with many functions off, so the consumption should be low. Also, one run shouldn’t eat 5 days away.
The previous cycle I made a graph as well, and the same occured on different percentages (and only after a run). The difference then was that the drain was bigger and a soft reset helped.
It’s still following the green line. I’ll do a short run in a bit. Maybe that’s what the watch (or I) need!
We’ll see in a few days! I’ll keep sending Suunto batterylogs every cycle till the problem is solved

@Gideon-Kaempfer maybe it is time to start a new thread about battery physics.
Just to correct you:
the current battery charge level is not derived from a voltage measurement. Instead (as with all state of the art battery meters) the charge going into and out of the battery is integrated and subtracted from or added to the battery capacity.
As this method might miss a Coulomb here and there, the meter is calibrated when the watch is fully charged. At a certain max voltage the meter is set to equal 100%t6, S6, Elementum Terra, Ambit 3 Sapphire, Spartan Ultra Copper, Traverse Alpha, S7 Graphite LE, S9B Ambassador, S9P Granite Blue Titanium, S9PP Titanium Sand, Vertical All Black, Race Titanium Charcoal, Race S All Black / Titanium Courtney, Run Lime

@Egika there is so much stuff that happen while I innocently running with my watch
-
@Dimitrios-Kanellopoulos Yes, the “ghost” bip/buzz when you power on a BT sensor is still there. Battery drain also, because it seems that BT process continues searching for BT devices as in the previous sw version.
Verified (and easily reproducible) in my Suunto Vertical.Suunto T3D, Suunto Spartan Trainer, Suunto Spartan Ultra (retired), Suunto 9 Baro (retired), Suunto 9 Peak (retired), Suunto Vertical Titanium Solar, Suunto Race S.
-
@thanasis According to my tests (also performed with the previous software) th BT connection process keeps searching for devices after finishing activities. I can reproduce the behavior just powering on my Heart rate sensor (Coospo), the watch bips and buzzes when connects to the sensor, in the watchface screen outside activities.
If you soft reset the watch, BT connection process is restarted and doesn´t search for devices until you start another activity.
In my case this is causing a 12-14% battery drain by day outside activities (Vertical Solar Ti).
I sent logs to Suunto.
