Apple Watch 6 - No Vo2 Max data

I bought a Series 6 to replace my Series 4 and set it up and restored it from the final Series 4 backup and found that no VO2 Max readings were generating. I went into the Health app and did a manual VO2 Max entry and it's been working fine ever since. That’s the only thing I did to try to fix it - no resetting, unpairing or restoring, etc.

good evening, I replaced version 4 with 6 and I no longer see the vo2max in the health app.

this morning I reinitialized the Apple Watch 6 and activated the airplane mode on it. after a gentle 25 minute walk, the vo2max reappeared! tomorrow I'll do the counter-check and take the airplane mode off the clock.

I just followed the intsruction/hint above:

“From your iPhone>Watch>Privacy>Reset Fitness Calibration Data>Tap this

you just get a confirmation box that tells you that your metrics will not be as good if you to this.

Tap confirm and do it. You will get nothing else, no confirmation but it is done.”

As my watch did not measure before any data I put manually for 6 month back. Since than my watch measure perfectly....

I have the same problem. But, despite re-calibrating Apple Watch 6 two times, I still get no VO2 max data. Both the watch and the phone have the latest updates. Is there a way how to fix this (a future update, perhaps)?

I have tried re-calibrating numerous times, but the issue persists.

I have an Apple Watch SE and an iPhone Xs, and I keep both updated regularly. On my last attempt to correct the problem by re-calibrating the watch, I was running watchOS 7.3 and iOS 14.3. This is extremely frustrating. Although I have gone on about two dozen walks or runs of 20 minutes since I bought the watch several months ago, it has only collected data on one occasion. This would be frustrating under any circumstances, but the fact that apple does not appear to have addressed the problem despite hundreds of people reporting the same issue makes me furious.

I have an apple watch series 6. I noticed that starting in Dec 2020 that it no longer records Vo2 Max for hikes. As a result my Vo2 Max has decreased significantly. Did something change that hikes are no longer included in Vo2 Max?

Has anyone had any positive feed back with the problem? It looks to be coming up to a year now of not working. Also seems like Apple are too busy working on marketing their online subscription palates videos. How about focusing on what I spent $1600 on, which you broke when you made changes to the platform. Surly if you can create an Apple MAC chip you can get your engineering to get Vo2 working. Or change the platform back!!! How can you sleep when your products don’t quiet work??? I kind of feel like after speaking with my senior advisor that if I don’t like the fact that the feature doesn’t work. I should move onto a different product??? Kind of makes me feel a little sick to be honest as I have been a loyal customer for a number of years.

Had this issue. Worked fine for 2 weeks the just stopped. Tried all methods mentioned in this thread then found the issue.

before doing anything else try wiping the sensor with a wet wipe. Build up of sweat had affected the connection

hope this helps

Yes I clean my watch all the time. My data from activity does not transfer. Apple are having issues with the platform. Thinking COVID has shut down their progress in life. If you call the Apple number they will first stall you. Then after a few weeks tell you to keep an eye out for updates?

Mine was doing the same thing for MONTHS. I finally figured out that my watch was somehow on “Power Saving Mode and wasn’t recording heart rate during workouts.

I toggled this off under Watch > Workout > Power Saving Mode. No issues since.

guess I can add 4 other Apple Watch 6's with this problem. I have tried everything mention on the messages below with no change. MyApple Watch 5 has no problems with Vo2 Max. The other 3 Apple Watch 6 with this problem are people I know locally who have upgraded to an Apple Watch 6. The Apple Watch 6 OS seems to have no effect it goes from 7.4 to 7.1. Two of the other Watch 6's didn't even use the Vo2 Max for months and it never turned on.

It seems to be a bug with the actual hardware. Non of the Watch 6's have a Data Source for Vo2 Max while my Watch 5 has three. And I can't add a Data Source to Vo2 Max but I can add one to other things like running or time.

I will return the Watch 6 in a week if this doesn't work and go back to my Watch 5. Apple has no been very helpful in this is understanding this issue.

I just got my new iwatch 6 and the same thing happened. No vo2max reading, that is until I manually entered a vo2max recording at the lowest level (10).

Then I went for a 30mns walk using the work out app. And lo and behold, the vo2max recording is now working. Try it.

Sorry it didn’t work for you, but it did for me, so I guess it’s not a total write off.

It pays to give it a go, just in case it might work, as it did for me.

Apple really needs to fix this issue.

cheers,

Mine worked when I updated the watch 4 times. Readings were way off. Put that down to maybe a few required to get the data. Showed 35, 35, 37 and 35 on last entry received from the watch.... Garmin is around 50???

once I updated my iPhone data stopped transferring again. After a 45min activity.

not sure Apple are applying their full resources to rectify

every day my watch looks more and more of a gimmick. I’m pretty sure the cheap rip off does the same too.

sad thing is when it worked I thought it was the best product on the market. Snubbing Garmin solutions.

but that’s when Apple’s just worked

I have a watch series 4 and similar issue exists after recent watch os 7.x update . My VO2 Max readings stopped to be captured / recorded . Have tried lot of options suggested here including resets , manual VO2 max entry, restoring from previous backup , restarts and nothing seemed to be working yet. It’s annoying to not rely on vo2’max trends especially when Apple markets them to users as that’s one of the metric and keeps us motivated to get out and log more workouts work . If Apple cannot make this consistently working across its line of watch os devices they should prioritize and fix their software.
