Wrist power instead of Stryd?
-
@jschmidt can you elaborate what makes you think so?
-
There are many points that make me think so: The power values are less responsive (they feel more like 10s than 3s), they are about 10W lower, I see drops (the value goes to zero and goes again up to its former level). I’m using Stryd for many years but never saw such reactions.
-
There is a known issue with the drops to 0w originally reported for the Race S but I think now also reported for the Race and the Vertical. I know what you mean regarding the 10s response time with the in-built power but I’ve not noticed this (or the 10w difference) on my Race S even though I am seeing the drops to 0w. I’ll pay more attention to power rate of update on my run tomorrow. There’s some confusion whether the issue is a display bug or a bluetooth problem or something else. I’ve tried to test whether it’s related to the environment but have not found any patterns. FYI, the original issue on the Race S was reported very quickly after the latest firmware update so the conversation about it is in that topic.

@far-blue Should not be a Bluetooth problem as it also happens with inbuild power
-
@jschmidt as others said, sounds like the known issue related to power drops to 0 that’s is there in the last couple of software updates… Validate power avg values between Suunto app vs Stryd app specially for structured workouts. If there’s a big difference in watts in the manual laps, this confirms the known issue.
-
Thank you guys for all your answers! I did a search on this forum before I made this post but it looks like I missed that this is a known issue. I’m wondering a bit why I didn’t notice this during all of my running sessions in the past. But anyway, maybe I began to watch at my wrist too often… Finally I resume that I have to wait for (one of the) next update to get out of this minor trouble.
-
I checked on my latest run and the power values are updating as rapidly as I’d expect from stryd so my gut feeling is that the stryd is being used.
Yeah, we are all just waiting now for Suunto to identify the bug, fix, test and release an update. In the mean time, the consensus is that the recorded data is fine or, at least, good enough so the issue shouldn’t impact your stryd dashboard, the Suunto App or any 3rd party services you use.

@jschmidt yes same here… I even purchased the latest Stryd pod as my previous was 2-3 years old. Didn’t help
I also see the 0 W drops. Annoying! Today I tried the Suunto+ Stryd app and there you can see the correct watts. However, that doesn’t help when my training makes use of the interval avg watts and those are now garbage watts.Anyone tried if booting the watch helps? To me it almost seems like wrist power is shown every other run and Stryd power every other. If only the Stryd watts were visible for proper workouts or sessions and wrist watts for easy runs. I could live with that
I have Suunto Race. I got Suunto Run for my wife recently… maybe that watch doesn’t have this bug and I could use it for sessions? She won’t be happy to hear this

@Hannu-Liljemark power drops to 0 are known issue for the last couple of software updates, it seems fix is ready in testing software. You’d need to wait for Q3 update or roll back to 2.40 firmware version.
As for S+ Stryd app, long story short just avoid it
-
@herlas thanks for the info! I’ll wait.
Regarding the S+ Stryd app: Stryd customer support recommended the app after I reported an issue where Stryd reports double distance in the offline sync files.
I guess I’ll just document it here in the forum (it’s more Stryd issue maybe): I stop running, press stop on the watch, and wait some minutes before offline sync. Then in the offline sync data in Powercenter I can see that eg. 55:01 I had ran 9km and 55:02 I had ran 18km
I think the 55:01 and 55:02 is somewhere when I pushed stop on the watch. Anyway, this was the previous pod. And it’s only for some runs. And it’s only Powercenter data and does not seem to skew my RSB numbers so it’s not really important. If I cared about Powercenter weekly kilometers then it would be annoying.Honestly I like the ritual of offline sync and having a reliable secondary source of data if watch crashes. So now that you recommend avoiding the S+ Stryd app, I might take your advice.
Edit: I read your earlier posts on the forum regarding the app. Wow, if it’s still the same that really is dissapointing. Who would want to use the app at all
Interesting you mention the wrist power vs Stryd power display issue already in your Feb 2024 reply to a thread. I just wonder how come I’m only experiencing it since maybe May 2025 and I think I’ve had the Stryd app installed (not toggled enabled) since its release. -
@Hannu-Liljemark I did a lot of trying the last days: Using the S+ app is no option. It didn’t record all the Styd metrics and merging afterwards isn’t possible anymore. I thought “Ok. Why complaining about 10 Watt lower values?”. But after some runs it kills my critical power on powercenter! My actual workaround is using my old Garmin watch,
!
By the way: The Suunto run doesn’t support the Stryd. So your wife won’t be hurt by this issue… -
@jschmidt I hear you! Yesterday I removed the Stryd app, rebooted the watch. It was my tempo day and watts were correct
Today it’s my easy day and we’ll see if the watts are okay again 
Saturday was my long run day, and the wrist watts were 40-50W below my Stryd watts. I had to run based on how I was feeling, what the HR was and what the Stryd screen was telling me about the realtime power. All was okay on the end - my Z2 guesstimate was only 4% off from what training program had prescribed 
Anyway, these technical issues are always annoying and can make session/workout days difficult. Like you mention, if you have critical power tests or races it can be difficult to make use the race planner’s recommendations.
