@Dimitrios-Kanellopoulos There will be significant battery drain if the backlight stays on after starting an activity, as has been reported by a number of us.

@thanasis Perhaps this is also the cause of your observed behavior?

@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.

Dimitrios Kanellopoulos

@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.
