iOS 18 update and Missing Health/Fitness Data

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.

Check this out. iPhone-only sleep tracking has indeed been removed from iOS 18.

The only good healthy feature I used for years, now you removed it? For what? Make more money to buy a watch?! Maybe I won’t update iOS anymore and buy other brand cell phone in the future and remove iPhone totally!

It would have been nice to leave the toggle option to record the data or not. Not everyone can afford nearly 1k for a watch. The fact that Apple just removes the option for those disadvantaged shows the lack of respect and consideration for their buyers. I mean face it, if it wasn’t for the buyers, they wouldn’t have their billions.

It’s a health related feature. Don’t remove it, try and improve it.

I’m in need of an upgrade but given that feature removal, I’m going to go with a different brand.

Apple told me that the Health app has never been able to track sleep duration, unless we have an Apple Watch.

This cannot be true. My iPhone XS Max has been tracking sleep duration unless duration for years. And I do not own a watch or a 3rd-party sleep app. This is frustrating.

I recently bought the new iPhone 16 Pro Max and unpaired my Apple Watch Ultra from my old iPhone 14 Pro Max. Everything works perfectly—my Apple Watch Ultra collects data like calories, ECG, breathing, etc. However, in the Health and Fitness apps on my iPhone 16 Pro Max, I only see data from the last day of migration. Oddly enough, everything else like music, messages, and Siri works fine. I’ve tried calibration and location settings, but nothing helps. I don’t want to reset as I might lose data. Any suggestions?

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.

I have the same problem. It appears the sleep tracking will no longer be available

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.

Tired of this nonsense too!

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 🤷‍♂️

My husband and I are both also experiencing issues with sleep and exercise recording with our Apple Watches since the iOS 18 update. I hope it’s resolved soon

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