@thanasis well not completely. Let’s let a little time pass. I’ll prepare Also some tools

@Zdeněk-Hruška This has been a long-standing bug with Suunto watches. If GPS is locked, the watch will source pace and distance from GPS, not from Stryd. If GPS is not locked, such as running on the treadmill, then Suunto will use Stryd for pace and distance.

I’ve raised bug this with Suunto support a few times, so hopefully it gets fixed.

@atoponce nope I don’t think it works like so.

@Dimitrios-Kanellopoulos That’s what I’ve observed. Here is a recent outdoor 5K race with the Stryd Next Gen pod paired to my Race S. The paces differ:

Here is a treadmill workout. The paces perfectly agree:

This is reproducible on every run I do outdoors versus indoor. When GPS is locked, the paces with Stryd disagrees. When GPS is not locked, the paces are in agreement.

This is a 5K race that alerted me to the problem. Suunto reported the distance as 5.19 km when the the course was actually short at 4.63 km, which Stryd correctly calculated. Note that Suunto’s pace is consistently higher than Stryd’s, and thus for the duration, resulted in a longer distance.

@atoponce afaik you should turn off auto calibration but this was long time ago for me with stryd. I’ll ask internally

Zdeněk Hruška

@Dimitrios-Kanellopoulos that doesn’t work unfortunately. I have all Stryd data turned on and calibration turned off and if I am lucky I will get a power from the pod. But the pace is always from the watch (I tested with different settings and hand movements). Maybe I am wrong but it seems like that’s really the case and it shouldn’t be.

@Dimitrios-Kanellopoulos Thanks for raising this internally. Auto-calibration is disabled, but auto-calibration is a new feature with the release of this firmware. I’ve checked several runs going back to January 2025 when I purchased the watch. This bug has been present since at least that point.

Hello,

I had the following problem today (similar to 3 months ago):
31% battery in the morning
30% training start trail running: battery mode endurance
19% at training stop after 3:42 h (!6.30h)
Door unlocked, toilet, alarm 9% (16.35h)
1% 16.45h
Battery usage since the last full charge:

Jan 11: 100%, 12.30h
Jan 11: 95%, 3.25 h training (endurance mode) 16.30h
Jan 12: 92%, 10h
Jan 12: 86%, 3h training (endurance mode) 16.30h
Jan 13: 84% 10.15h
Jan 13: 77% 3.5 h training (endurance mode) 17.15h
Jan 14: 74% 11h (no training)
Jan 15: 68% 10h
Jan 15: 60% 3h training (endurance mode) 17h
Jan 16: 50% 10h
Jan 16: 40% 3.5 h training (endurance mode) 17h
Jan 17: 31% 10h
Jan 17: 19% 3.75 h training (endurance mode) 16.30h
Jan 17: 1% 16.45h

Until Jan 15 everything was great, then a 10% drop overnight is not good, and going from 19% to 1% in 15 minutes is unacceptable. I normally charge the watch once a week at about 20%, I bought it in October 2023. I had this jump from 19% or 18% to 1% about 3-4 weeks ago as well, but without any training beforehand.

What is going on? Ideas?

Dimitrios Kanellopoulos

@atoponce auto calibration was there before as well. Back when I was using stryd I vaguely remember this setting. I’ll get back to you guys about this.

Zdeněk Hruška

@Dimitrios-Kanellopoulos thank you very much. I think there are more threads regarding the Stryd not working properly with Suunto in this forum as well as on Reddit for example (especially about pace and distance not coming from the pod). I haven’t used Stryd for a few years. I remember that it worked flawlessly before. There are definitely some issues now. And it seems to be the case that on the treadmill it works as it should while on the gps profiles watch seems to prefer gps data. At least from my experience and testing.
Thanks for all the help!
Edit: Also there was a pairing issue with the new 5.0 Stryd but that one had been sorted out by the Stryd update.
