Known workaround while Suunto fixes power drops and issues with power averages on manual laps is to go back to firmware 2.40.
I’ve just gone back to firmware 2.40.44 on my Race S, still getting power drops.

correct, using Stryd via S+ is a separate Bluetooth connection
That’s what I noticed. I was just curious if the S+ app would be “sharing” its data to the watch, but it appears it’s all self-contained in its own walled garden.
I’ve said it before many times, Stryd through S+ app creates more issues than it solves.
I need to frequent the forums more. Heh.
- Power from STRYD is displayed only on the S+ screen
- Power on regular screens comes from watch itself
- No pace, distance or cadence will come from STRYD.
- Once S+ is connected, Stryd won’t be available as neither power meter or foot pod
- It creates fit file with 2 power sources Suunto’s and Stryd’s
Perfect. Thanks!
- This breaks Stryd offline merge, Stryd didn’t create this S+ app it was Suunto, so Stryd hasn’t done any additional processing on their side to make offline sync work when workout is made with Stryd s+ app
Yup. I sent in a support request to Stryd about merging the two runs in PowerCenter and Angus said it’s not possible and advised me to not use the S+ Stryd app.
Which surprised me, as I thought Stryd did the development. But you mentioned that Suunto did, so it’s even more curious that they didn’t develop the app to use the existing paired connection with the foot pods or share the data out of the S+ app to the watch. Shrug.
Bottom line, stay away from Stryd S+
Angus advise the same. Haha.
Known workaround while Suunto fixes power drops and issues with power averages on manual laps is to go back to firmware 2.40.
I’ll look into this. I’ve already downgraded to .8 and noticed the power drops remain, so I’m skeptical this is a fix. I suspect that the .12 firmware changed something that downgrading isn’t reverting. I’ll give it a go for tomorrow’s easy run and see how it goes.
Thanks for the confirmation and reply!

Suunto FIT pulled from the app vs Stryd FIT pulled from the pod via Stryd powercenter.
If Suunto is syncing the data to Stryd, then I would expect them to be the same. IE, Stryd shouldn’t be manipulating the data Suunto syncs.
With that said, I don’t know how the offline sync interacts with the existing data. Does the data on the foot pod(s) overwrite the existing power data Suunto already synced over?
I wonder if for some reason Race S records its own wrist based wattage instead of Stryd power. However, why just sometimes.
I don’t think that’s the case if the pod(s) are connected to the watch via Bluetooth. The power data written to the storage on the watch should be coming from the pod(s), not the watch.

This is what I suspected. I’m going to give it a go for my next run and see how it behaves.
-
@Dareo, I have the same problèm ! Every night, my watch switch Power off! Have you a tips ?
-
@Likarnik I recognized this behavior, too… never saw that before

@sryke I just plotted the power for my runs for M-F, including the Tue/Thu doubles. I’m grabbing the Suunto power data from the FIT file downloaded via the Suunto app. I’m grabbing the Stryd data from the JSON file on my Android phone using
adb pullafter doing an offline sync. That way, I’m getting the unadulterated Suunto and Stryd power data without any shenanigans in PowerCenter.They all agree except Wednesday and Thursday AM. Wednesday disagrees, because I paired my Stryd pods with the Stryd S+ app, which means the power recorded to the watch was Suunto’s built-in running power, not Stryd’s.
Thursday AM disagrees in the 4th interval because I paused my watch at an intersection. As such, Stryd’s power data is shifted to the right of Suunto’s as Stryd ignores pauses. However, you can still see that the data would align.
Friday morning before my run, I downgraded the firmware on my Race S to 2.40.44 to test if the display would still drop power. It didn’t thankfully, so I think I’ll stick with this going forward.

I just ran with 2.40.44 and didn’t see any power drops on the display. I was getting it with 2.43.8 however. But 2.40.44 worked for me.

@atoponce Thank you for sharing these details. Your findings aligned with mine. Raw data is not the problem which is a relief. What was changed in the latest firmware I guess is the way Suunto app and watch interpret the power data. When I use a 3rd party tool to analyse power data from Suunto’s Fit files, the average numbers tallied with Stryd’s and not the Suunto App’s and the watch’s.

@deltof Sorry @deltof but I can’t say that I do. I’m still waiting for this supposed “priority” hotfix that tech support told me about in the chat. Since the problems started 17 days ago my watch has frozen or completely shut off 5 times at night while sleeping. So it’s intermittent, not constant. Same with exercising. Sometimes it freezes up on me during a session and sometimes it doesn’t. I have no clue what triggers it. What I have found is that when it freezes up during exercise, it’s futile to do a soft reset because it will freeze up again shortly thereafter.

FYI - today, 2.40.44

@sryke Wow, all those drops were failures? You didn’t stop during the run? If yes, then power is not usable with this bug.
In my case I see drops on the watch, but not in the app - strange. But I don’t trust the values after having the drops on the watch and reading experiences like yours… -
@sryke hm okay. Todays Run with Suunto RACE with 2.43.12 with no bugs.
-
Most drops are failures, I did compare it to the Stryd fit file data.
And you’re certain that this is really the Stryd pod power stream? Everytime I do not see any drops in the data is when I get an overall different wattage in the Suunto and Stryd files. My assumption is that the Race S sometimes does not read the stream from Stryd but uses its own wrist estimated power. Despite having a connection with the pod.

@sryke i dont have a stryd pod. Its suunto Measurement
