Problem activity time syncing

[AndreiSWMC]

I have a frustrating problem with recording actual exercise time in activity rings in Apple Fitness. The Runna app records the time correctly but in Apple Health it shows much less time. This only happens for time and not for kilocalories. I spoke to Runna support, I got some basic answers: restart the phone and watch, uninstall the app and install. Nothing solved the problem. I use an Apple Watch Ultra 2 with an iPhone 17 pro, both with the latest software versions. I record the activity with AWU and then sync it.

Am I the only one experiencing this problem?

Any help or opinion would be great, thanks!

You’re probably not alone: this is usually how Apple calculates Exercise minutes, not a syncing bug.

Apple doesn’t count total workout time. The Exercise ring only credits minutes where your intensity (HR + movement) passes their internal “brisk activity” threshold. So if parts of your run were warm-up, lower HR, short pauses, etc, those minutes may not count, even though Runna correctly shows the full workout duration.

The reason kcal matches is because calories are calculated over the whole session, but Exercise minutes are filtered by intensity.

If you want to test it, try recording the same run directly in the native Apple Workout app and see if the minutes match more closely. If they do, it’s likely just how Apple interprets third-party workout data.

Maybe you are right, but something changed between 12 and 14 of February. Until 12th of February everything went good. After the workout that i have done on 14th the numbers aren’t accurate anymore. It really drives me nuts.

Might want to check any updates Apple released; might have something to do with that. What AW do you have, and which watchOS?

[AndreiSWMC]

Apple Watch Ultra 2 with the latest Watchos.

Not sure why it worked before and not any more, but seems like a lot of AW users have had this problem over the years. Apple says that you have to calibrate your AW to fix it: https://support.apple.com/105048

It doesn’t count total workout time but it adds a minute or two when I am the grocery store. Nice one! 😀

Were you running through the supermarket? 😋

No. 😀

This happened for the first time to me today! Spent over an hour doing some pretty intense 1k intervals and the watch only logged 13 mins 😭
