Health app draining battery on iOS14

Thanks for the tip, @PhilWu.

Had the following issue so far on iOS 14, with iPhone 11, 64GB.

Health App taking up >2PB (PetaByte) of space. When I tried to backup (with encryption) it filled up my C: drive (120GB free) and failed. Had to stop the backup.

I will try to Backup iPhone WITHOUT ENCRYPTION, reset and then restore.

I re-installed the iOS14 with IPWS and restored it from iCloud and it looks like the battery drain is now gone. The phone doesn't start heating up when I unlock it so it's already a good sign. Will test it for the next couple of days and see if something changes, but everything looks good so far.

Exact same issues here. My iPhone 11 Pro Max has been 100% charged, I closed every single app, and battery is at 40% within 4 hours while literally not using the phone during that time. I have reset my phone and watch over 10x in last week and doesn’t help.

My health app is using 80% of my batter while not even using and I am unable to disable Health or Sleep apps.

I have been with apple support for so long in the past two days. They are claiming it’s a hard ware issue and want me to send my phone back. Which is absolutely isn’t. They have said they will let the senior advisor know.

Update: since I did those steps the health ap is no longer eating my battery! Only problem is is that I can not use the health ap. Also when I try to open the health ap in settings it freezes and will not open. The same goes for in my watch.

I experienced the same issue on iOS 14 / WatchOS 7. Very fast battery drain, overheating phone. Extremely frustrating.

However, the latest updates (14.0.1, 7.0.1) seem to have solved the issue! I recommend everyone to try upgrading before doing any phone resets / data wipes. Hope this helps.

Same issues here! i noticed today that they released an IOS 14.1 software update although it did not notify me, I manually went in and checked. Installing now so crossing my fingers that this fixes the Health/watch issues!!!

I had the same issue. You should talk to Apple support so they can log the issue. I found the fix for me which was settings -> general -> background refresh and turn it off for all. It fixed it. Instead of my phone dying in an hour and the Health app using 80% of my battery, I’m able to use my phone without it dying. Not really a fix but definitely a good temporary solution. I was surprised it worked because health app is not in the list of apps for background refresh. Hope this helps.

I’m glad I found this thread and that I wasn’t alone. Depleting battery, hot phone, unable to delete apps, Apple Watch not syncing and any app related to health constantly crashing.

I’d already noticed that Health app was always at the top of battery usage, but I hadn’t quite clocked how much storage it claimed to be taking up.

14.2PB.

PB. Not MB. Not GB. Not TB. I had to Google what on Earth a PB was. A Petabyte.

Nothing I tried helped other than to back-up and perform a fresh install having disabled syncing of Health app. That is how I spent my Sunday morning, but it seems to have worked. No more battery drain, Apple Watch syncing and Health app behaving itself.

Toughmonkey - I would just reset the device - erasing all data. Then it will take you back through the start up wizard and you can restore a back up. Make sure you do a backup before the erase all data and settings.

Basically as others had said. this is all assuming you have an iCloud storage account. I have the 2TB account and therefore don’t use a computer based backup. I’ve read that others have had issues backing up to computer as the computer has been confused by the presence of Petabytes of data, whether it exists or not.

In Settings>Your Name (Apple ID)>iCloud>Apps using iCloud>swipe off Health App.

This was a precautionary step to stop it trying getting confused trying to back up Petabytes of data. Whether that was necessary or not, I don’t know, but I followed the advice of others and it seemed to work. My Health App data that was already backed up restored correctly after the next steps....

To backup your device: Settings>Your Name (Apple ID). On this page choose the device you wish to backup. It’ll list every Apple device you have linked to you account to select the correct one >iCloud Backup>Backup Now

It asked me if I wanted to backup before I erased my phone.

To check the status of your backups for peace of mind: Settings>Your Name (Apple ID)>iCloud>Manage Storage>Backups. On this page it should list your backups. Choose the device and check when the last backup was. If it’s up to date in line with when you last backed up then you should be good to go.

Now you’re ready to press the nuclear button. Settings>General>Reset>Erase All Content And Settings.

Follow the onscreen instructions from here. It asked me if I wished to keep my carrier’s details to which I said yes. After it had finished deleting it detected my iPad and setup my Apple Account with a funky moving image that my iPad scanned and allowed to sync settings. Then it asked if I wished to use my Backup (yes) and off it went.

I needed to set up my Face ID and Apple Pay details, but other than that everything else came down. It took about an hour for all of my apps to come down, and 30,000+ photos but everything returned to normal. Afterwards I remembered to resync Heath App to iCloud and all apps and devices are behaving as they should. sleep tracking worked last night and the Activity app is showing all data, current and historic.

This is on iPhone 11 using iOS 14.0.1 and Apple Watch 3 with Watch OS 7.0.1, with all fitness apps including Health App, Activity, Runkeeper, MyFitnessPal, Nokia/Withings Health Mate that were previously not working correctly now syncing between devices.

It was a royal pain to have to do it all, but it’s been over 24 hours and everything is behaving as it should.

Thank you very much Toughmonkey for detailed solution.

It looks like it worked for me, but I’ll check that in the morning and see if sleep was recorded properly.

After I applied this fix, I got scared since it didn’t show any info about my sleep (in AutoSleep app) for last year, but after a while, all the data has returned.

Wish all the other users to have successful fix too.

Hey guys... just a quick update. My problem is fixed... Not 100% sure what did it - updated to 14.0.1, and deleted all my health data, turned off all the fitness tracking - and the battery is fine. I slowly turned back on fitness tracking and manually started adding all the app permissions on one by one to see if there was any degradation, but so far so good. I've got to the point that all apps are on and tracking, the battery life is back to the way it was - 2 days without a need for charge on an 11pro max. It's still reading PB's of data though... I'm thinking it's not possible that we've all accrued that much data, and it must be a reset-logic error... or we all have more data than many large enterprises :) Sucks to have all my fitness tracking gone, but it is what it is, I suppose.

Hope you guys figure out your

Geeeeeeeeeeeeeeeeeee - As I mentioned, I got my size down to the actual size. I turn off icloud health (you won't lose the data) on the phone, did a clean install (reset all data and settings) and then turn icloud health back on. This will give you a fresh start. I didn't do a restore but I think you could do that as well. Just my actions....

I’m having issues with battery drain as well. Looks to be the health app.
