Vo2 Max not updating in health app using Apple Watch 7

Does it have to be a walk or run? My vo2 max stopped measuring on Jan 30 after being measured for years. I do a 20 min bike ride every other day and I’m not getting anything…

I did an outdoor walk today and still my series 6 didn’t measure VO2MAX

I just went from an Apple watch series 2 to series 7 and have noticed two things.

1) My VO2 (tracked for only one day) went from 39 to 30. I have trending data for my series 2 watch for at least 6 months.

2) It no longer shows VO2 for the past two days of work outs.

My watch and phone have the latest software updates and I believe all my settings are correct.

I did however try this step below and got stuck on step 2 as there was no way to click on "Set up."

Next, make sure that you didn't miss anything when setting it up. Review the steps in this article: Set up Cardio Fitness Levels - Apple Support

I only have until Saturday(Jan. 8) to return my watch and would like some help.

To get a VO2Max figure it has to be an outdoor walking,running or hiking workout.

Hello Gerhard308,

Thank you for using Apple Support Communities.

We understand that you are having an issue with your new Apple Watch Series 7 not updating your Vo2 Max to the Health app. Here are a couple of things you can try to see if you can get it working.

First, update your Apple Watch, we understand this is a new watch, but there may be an update that was released after the watch was manufactured See this article for a reminder on how to update the WatchOS: Update your Apple Watch - Apple Support

Next, make sure that you didn't miss anything when setting it up. Review the steps in this article: Set up Cardio Fitness Levels - Apple Support

Next, check the Motion & Fitness privacy settings. On your phone go to Settings > Privacy >Motion & Fitness, make sure Fitness Tracking and Health is turned on. On your phone, in the Watch App, to to My Watch > Privacy and make sure Fitness Tracking and Heart Rate is turned on.

And finally, if you are still not able to get it to update, Contact Apple Support directly for more specific troubleshooting assistance.

Best regards.

Try to unpair the watch and pair it back that should work.

if that didn’t work then go to watch app privacy then reset fitness calibration that should fix the problem

Check you’ve not got power saving mode on. That’s was the issue for me

Did you get any advice on this matter? My VO2max also dropped from 43 to 36 after changing from series 1 to the latest. :( Which result is correct, and what makes the big difference?

Just been through support with this. If heart rate chart is also not showing then Turn off your power saving mode !! Job done 😊
