Deleted all of the Health App data, however is still showing as using 20.44GB

Apple’s recommendation worked for me. I had 1.6TB health data, no longer recording route data from my Apple Watch walks and cycles. My first attempt was to unpair and then repair my watch was not successful. My second attempt was successful. 1. Unpair Apple Watch (2nd gen) 2. iCloud backup (I have 2 TB option but backup no where big as 1.6TB or it would have failed), 3. Reset my iPhone X (side effects - had to add credit cards back to wallet after restore), 4. Restored iPhone X from iCloud backup ( storage report was back to expected value - all good) 5. Repaired Apple Watch. 6. Went for a workout walk and noted that activity app on iPhone X recorded the entire walk route. Big success! I needed an evening to get this done.

Same issue. Updated to iOS 14 when it came out. No issues. Went to bed yesterday with over 50gb of free storage, health was no where near where it’s at now. Woke up to a full iPhone and 30.83gb of Health data. Deleted almost everything and now it jumped UP to 31gb. And I cannot delete the app.

I left out the detail that my heartbeat rate only went back 2 months. After I went through the Apple recommended procedure my Apple heartbeat rate was restored back nearly 3 years to when I got my Apple Watch.

I thought I was going to win with 31TB, but I was too late :).

If I add up the space below the Health app the phone is full with the other apps. So it would seem this is not the issue and we would not have noticed had the phone not really been full. It is still very odd. Actually I was pleased it said PB as it had to be wrong and was not the issue. If it had said 20GB as the first post said I would have looked more at the Health app. 14.0.1 didn’t fix it.

My health app is at 61.62 PB lmao, 61 million Gb of data, even the tech that I spoke with on the phone had never seen it before after he connected to my phone to view it himself. No clue how to back it up without restoring the phone to new :/ even after deleting the app and deleting all data from the health app, its still there. I'm going to wait it out and hope next update its fixed.

Same problem here. Health data showing 9 PB which makes no sense. And how was icloud taking up my local storage space? The idea of using icloud since the beginning was all about saving local storage space, not vice versa?

It’s taking up ALL my storage - I’ve never had an app take up this much storage and it’s draining my battery - i went from 95% to it completely dead in less than 2 hours - this is a new phone - *** Apple.

Ironic that Apple suggests i delete media from my text message but won’t bother to fix this massive issue with their software update.

My health app is also reporting PBs of data. After I installed iOS 14 my phone was really heating up and I discovered from the analytic logs that it was caused by the health app consuming 99% of CPU for long periods of time. Then I tried to backup my iPhone to my MacBook Pro with almost 1 TB free space and it kept failing due to lack of storage space that's when I discovered the health app reporting 23.17 PB of storage spaced used on a 256GB iPhone.

After the latest (IOS 14.0.1) update - I have at least two issues; 1) earlier my total calorie burn per day was in the region of 2,900 to 3,200 per day. Since the update however my total calorie burn is about half of my usual daily burn rate - down to about 1,400. This is despite not having made any significant changes to my lifestyle. 2) the Health App is showing storage usage of 1.61TB, on my 64GB XR iPhone!!

I tried if I can backup my Iphone...will not work. Not enough space available in my laptop.

This could be a major issue and I am not sure how can Apple provide a way to update my OS as there are no more space available on my mobile.

There were no issues yesterday actually and was still able to install a new app. The only difference I observed was when I wore my apple watch, it did not work and accessing the apple watch settings in my Iphone, also hanged. So I tried to power off-on both my watch and phone, and when it turned on, I noticed a new Apple Watch OS update. When I tried to update my Apple Watch OS, it did not allow me as I have no more space available. That's when I investigated my app storage and it was already full.

I am now thinking to restore to my previous and old back-up. Unfortunately, I was not able to backup prior updating to 14.

I have never used the Health app and have always kept data deleted, so I immediately noticed my storage dramatically increased when I updated to iOS 14. My health app has 6.97 PB and I am unable to download iOS 14.1 for bug fixes and I cannot backup my phone either, so I am at a crossroads with what I can do here. Anyone have any luck so far with fixing this issue? I was really hoping apple would’ve given the option to delete the few apps that have always come with the iPhone as I’ve never used them.

I mean if it's possible to make a backup with corrupted Health data when it's 20+ PB, or MobileDevice service/iCloud will assume you indeed have 20+ PB of data and that there's not enough space for a backup.

Yes / No, so when I download an app it finishes the download but I can’t see it on my Home Screen or App Library, but if I reset my phone it appears.

same with uninstalling, just the opposite.

only noticed this today when trying to uninstall an app

yes I have 14.0.1 now, it resolved the overheating but now I am left with this issue of the health app over reporting the storage space used and I suspect it is the reason my Mac says it doesn't have enough space to perform a backup.

Has anyone tried going into Health settings > Data Access & Devices > Select "your device" at the bottom > Delete all data from "your device"

I have not tried this yet - wanted to see it anyone else has and was successful before deleting anything.
