Vo2 Max Not recordering

I am seeing VO2 max being recorded on my iPhone 11 Pro 14.0.1. I am going to bet this is related to the same sync issue seen with GPS data, likely from Apple rewriting the Activity App to the Fitness App. I had to RESET my iPhone.

Apple has been telling scores of people to RESET their phone and Re-pair their watches. Please read the following CAREFULLY or you may lose your data, particularly the iCloud backup part. Local backup to a Mac won't cut it,

Still no fix for me. I restored both my iPhone 11 Pro and my Apple Watch 6 and I set them up as brand new devices (no back up used) and the VO to Max still will not update after multiple workouts. All other health metrics update no problem. Last v02 Max update is still showing September 16 when I updated the iOS 7.1 and iOS 14.

I figured out the issue with mine. After restoring my iPhone and my Apple Watch and setting them up is brand new I still had no luck. Then I realized I was using my polar chest heart rate monitor paired to my watch when I ran. So I tried running without the polar and only using the Apple Watch and when I did it automatically updated correctly. This is still a bummer and clearly a software issue with watchOS 7 or iOS 14. I had no problems using the polar heart rate monitor up until September 16 and I was recording V02max without issue. I plan on submitting a ticket to polar and letting them know. Before and after photos.

I am having the same issue, Apple please help. Mine was until I updated to watchOs7. I had an Apple Watch 5. My Apple Watch 6 came today, after setup, I did a run and still no Vo2 Max data since 9/16. All other watch data transfers to health without issue.

Same issue here. VO2 max not being captured in iPhone health app anymore. I upgraded both iphone and iwatch5 and unpaired and paired 2x on 9/21. Since then - it stopped recording...even though the work out was captured in the iPhone's fitness app.

I have been on the phone w/ Apple Support to trouble shoot. Data is being captured in iPhone Activity but not migrating to VO2 Max in Health App. In short, I had to send screen shots of both so Apple engineering can fix. No idea how long this will take.

Apple - please fix this.

I have the same problem; iPhone 11Pro, Apple Watch S4. I updated to IOS 14 on the day it came out, but watch wouldn’t update at all, so I installed a watch beta profile. The watch then updated to watchOS 7.

I did do a run with the new OS and it recorded the VO2 Max.

I had the problem of excessive battery drain on the watch and despite unpairing/repairing a couple of times, nothing would cure this. I took the advice of setting up the watch as a new watch. This took a couple of tries too, but eventually I had set the watch up as new and the battery drain issue disappeared. Only problem now is that VO2 Max is not recorded.

In the Health app, the watch is not showing as a Data Source - that seems to be the issue, for me at least.

I wonder if any beta profiles allow the VO2 to transfer over?

I've reset the iPhone following Apple's advice. This time, I used iCloud (had to upgrade storage....) for backup/restore. Took a long time, and it still didn't restore my songs.

I've checked in the Health app, I'm still not convinced the Watch is being used as a data source (I believe this is why vo2 isn't being calculated). I'll go for a run tomorrow and see what happens, but it doesn't look promising.

I too spend a fair while resetting phone and watch, still no VO2max data and no signs of my watch being logged as the source for the VO2max. Apple have been gathering data from my phone regarding this issue. Will go for a run tomorrow also but like you I’m not feeling very positive as it’s the second time I have tried a full reset

New VO2 data requires I believe a 20 min outdoor walk or run with a constant heart reading. I was looking for the Apple reference but can't find it at the moment. I fear data between the upgrade to IOS14 and the phone reset is likely gone. I blame the new Fitness app. My watches are WatchOS 6, not 7, and the IOS 14 upgrade buggered the sync from some data types for both.

You can get your music back if you copy your iTunes library back from your computer. Apple does NOT back up your music, even with the "full" backup option. They tell us that in the fine print and easily missed.

Ah thanks for the music info. Knowing how badly wrong this could all go, I completed a full backup to my MacBook before backing up to iCloud.

I use RunGap so all my runs are stored thankfully. It also looks like my Health and Activity have been saved too, which is better than some others have fared.

I've read in many places that the watch needs a 20 minute outdoor exercise to register a vo2 reading. I'll be doing a long run tomorrow, so fingers crossed.

Lucky you. Dont even have any old Vo2Max data any more. Think reseting both OSs to clear this issue is just Apple clutching at straws. Its clearly an issue with the code in the IOS that can only be fixed with rewriting it. just going to have to wait for Apple to sort itself out.

Missing VO2 max data began with iOS upgrades with the new IWatch. I spent hours on the phone with Apple Support for nearly three weeks. Went through countless unpairing / restoring / resetting, etc. They tried to export the data logs from my iPhone to their server and could not do so.

My latest conversation ended with the support / engineer telling me that "I am dead in the water" and they have no current fix. Apple is better than this and my very first poor customer service experience. Simply bad service and a commitment to a remedy. I guess - just have to wait.

I found that it was when then IOS 14 went live, when i first started having issues. Support took data logs from my watch and phone on Thursday and they are calling me back on Wednesday.

Be interesting to see if the new iphone suffers the same issue.
