@Łukasz-Szmigiel said in The logic behind default GPS mode settings in different sports modes:
FYI: This is even more buggy than I initially thought. I just realized it as I was too lazy to change it to either Custom or Performance so I left it on broken post-custom Endurance. However when looking at path it seemed strange to me that the points plotted on the map are more like in 1 min fix instead of 2 min fix. So I’ve downloaded GPX from QS and it’s indeed 1 min fix.
It seems that S5 doesn’t switch to Endurance from Custom. It seems so from the UI but judging from the GPX - the track is actually saved in 1 min intervals, so:
There’s no OHR because the watch enforces Endurance and the UI changes to orange.
But the GPS mode is as defined in custom (Good = 1 min).
So what results is some kind of weird amalgamation Not a custom sports mode and not a default Endurance either.
Steps to reproduce:
Go to any outdoor mode
Go to battery modes, set custom
Set OHR on, set GPS good
Confirm custom
Notice start screen turns blue
Either exit start screen or start the activity (doesn’t matter, it’ll work this time)
Go to the same activity
Notice the UI changes color to orange, indicating the watch defaults to Endurance
Start the activity and record ~15 min or more
Check GPX for timestamps - after initial few minutes of 1 sec it defaults to 1 min.
Thanks for the heads-up! Sounds like a tricky bug with the S5 not properly switching to Endurance mode despite showing the UI change. The GPS fix sticking to 1 minute instead of 2, along with no OHR, definitely makes it seem like a strange mix of modes. Your steps to reproduce are clear, and it’s helpful to know what to watch for with the GPX timestamps. Hopefully, a fix is on the way for this!
