iOS 18 update and Missing Health/Fitness Data

SOLVED

Same issue with new iPhone 16 with iOS 18. I noticed my iPad has all my health data on it, so After trying everything I found on line to no avail I finally decided to go for it, and IT worked.

On your iPhone:

Go to settings.

Click on your account name at the top.

Click on iCloud.

Click on “see all” under the Saved To Cloud section.

Click on Health.

Turn off the “ Sync this iPhone “ toggle

EXIT out and shut down your iPhone and your Apple Watch.

wait 10 seconds then turn iPhone back on.

go to the same section and toggle the “Sync this iPhone” to On.

it takes about 15 minutes to download your health data from the cloud.

turn on your Apple watch now if you have.

after it’s done downloading, check your data. It should all be there. At least it worked for moi. Aloha🤙🏼

I called apple support. They had me remove my McAfee VPN. All health data is back. Haven't tried to reinstall VPN

I had the absolute same problem!! However simply un-pairing it and pairing it again solved everything

Called support. Told to delete VPN. Then reset system settings and reboot phone. It worked. Haven’t yet added VPN back in.

My husband had the same problem. I shut down all the apps, powered the phone down, and powered it up, and now it works. It's the old joke about the 4 engineers and the Volkswagen.

I called tech support and she had me turn on sleep/wake up in alarms. I left it on overnight and my sleep cycles returned. I was able to turn that alarm off and it’s been fine since. I hope that helps!!

After I installed iOS 18 the Trends data no longer populates. I can still see fitness data back to 2019 but the Trends area never populates. Apple Help Desk suggested unpairing watch then deleting and reinstalling the Apple Fitness App. I have not tried this yet as I’m worried about losing everything. I’ve been watching for a software patch ?

Working again now. As long as I don’t touch the phone or watch, at all, during the night AND set an alarm (that annoys the s**t out of me)

But vitals is still only tracking 2 areas. Sleep and temp. The other seem to have given up 🤷‍♂️

Hello there thank you very much for your post. The same issue happened here in addition. Also the Apple Watch app is disconnected to my Apple Watch actually and health data is missing ever since I upgraded to iOS 18. After I reset and disconnected my iPhone to my Apple Watch at least now they’re connected, but they still missing for my side, however my friends can see all the missing data from their health and fitness app. To be honest now I just regret updating to iOS 18, the whole iOS 18 stability it’s a joke.

Also facing the same issue. Long time iPhone/AW user for the past decade.

My assumption of where it went wrong is the fact that I did a full iCloud backup on my old iPhone 13 Pro Max which was not yet upgraded to iOS 18, and I got my new iPhone 16 Pro yesterday and everything merged fine so far (at least that is what I thought!)

few things to call out: I did not disable the Activation Lock on my AW to my old iPhone, I was told by an Apple employee that was processing my order that it wasn’t necessary. I went back home to restore my iPhone from my last iCloud backup. Eventually it was time to update/connect my AW, it wouldn’t pair or connect. So I had to reset my AW, “erase all data and settings” as instructed by Apple. Shortly after, I checked my Health App and it was still “downloading from iCloud”.

I still get the same **** message even thought I have been keeping my iPhone unlocked and connected to WiFi.

I am peeved and couldn’t sleep at all last night…My health data and monthly challenge badges GONE.

Hello!

I tried every option which was mentioned on similar platforms, sad but all turned out to be futile exercise. Tried deleting data and to my surprise even that's not getting deleted. Ultimately i deleted the fitness app.

After updating to iOS 18.1, I noticed that my sleep data is no longer being recorded. It seems this isn’t just my issue; it’s because the “Track Time in Bed with iPhone” feature has been removed in iOS 18.

I had years of health data on my iPhone SE and iPad mini 7, and now it’s all gone. I really dread updating my firmware because this isn’t the first time a new update created unanticipated problems. Frankly, something is rotten in Cupertino! As a long time Apple user (since 1984), I’m seeing issues with updates creating problems. 🤯

Hey, Buddy

I also faced the issue with health app,

Earlier I use to track my sleep data with my iphone only ( Without Apple Watch ) but after updating it to IOS 18, Sleep widget not tracking my sleep , I have tried everything but still the same issue ( No data Available )

Hope apple resolve this in upcoming updates.
