Health app draining battery on iOS14

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.

So disable Sleep on the Apple Watch . That will regain you your battery life . Use a third party app to track sleep until Apple resolve these issues .

I wonder if it’s iWatch 4 specific.. As always new tech tends to unearth the unexpected :)

sleepwatch , autosleep are all good apps .

I FOUND A TEMP SOLUTION. (Sorry if anyone already found this, I didn't read all of the replies.)

My phone was heating up and the battery was draining FAST. I went and looked and it was the Health app. My health app had been trying to download my health data from iCloud and it wasn't working. So it had just been running in the background the entire time I was using my phone. To fix it I went to my iCloud settings and turned off the Health switch. It didn't prompt me that I would lose data so I really hope I don't but also it wouldn't be the end of the world if I did lose that. That seemed to fix the issue.

TEMP FIX: so fix yesterday still holding, 36h without any overheating or battery drain. Health app using 2% battery only, still showing as 58PB storage though (although have been able to download new apps and update existing ones). Have been able to use the watch to monitor exercise and heart rate with no issues updating the phone.

Was for iPhone 11 with watch 3: turned sleep off on watch and phone, unpaired watch, forced restart on phone, re-paired watch, restored watch from last (os7) backup. sleep still off, not risking it until apple fix this.

good luck

Hi

just spoke to the Health team in Apple support about it. They release yesterday iOs14.0.1 and WOs 7.0.1 which should fix this.

good luck

I GOT A SOLUTION FINALLY.

It do not need to restore Apple Watch and if your Health data is in iCloud, nothing will lost.

1. Backup iPhone WITHOUT ENCRYPTION (encryption will backup health data which is massive)
2. Re-install iOS on iPhone and restore iPhone with the backup in Step1

And everything will be fine, watch is automatically connected, all app data is included.

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

I powered off my watch and Health App stopped draining battery. Health App still has 60PB and no other issue is solved. At least the battery is back to normal.

If you have an Apple Watch, seems like unpairing and pair a couple time will help this issue.

I removed the health widget... seems to stop killing the battery now... fingers crossed

It looks like updating to iOS 14.0.1 and watchOS 7.0.1 might have fixed this issue (for me).

Would have been nice of Apple to mention it in the release notes.

When I updated to iOS 14 back on Wednesday everything went smoothly. There was no battery drain and everything worked as expected. Then I noticed that workouts I tracked with Workout app on my Watch S5 wouldn’t display map view in the Fitness app of my iPhone 11 Pro. I tried to play around with location settings but nothing would help.

I re-paired my watch, workouts started working again. I went for a long run Sunday afternoon (without my phone) and I tracked the workout with Workout app. When I got back home the workout wouldn’t appear on my iPhone at all and that was the point when my phone started heating up when unlocked and Health app would be using 30% of battery. It looks like the watch can’t shove that workout through and Health app is stuck in the loop.

I tried to wait for it to sync up, re-paired my watch again, reset iPhone settings (without removing content and data) – but the issue still persists. I am now thinking of doing a clean install via computer.

What I also noticed is that the phone starts overheating when unlocked – there’s nothing happening when the phone is locked and idle – it just mellows out.

I’ll do an old-school iTunes backup and reinstall the iOS with the full OS image. Will post the results here.

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.

Just in case anyone hasn't already, it would be super useful to Apple if developers experiencing these issues can capture some debugging logs by following the instructions here:

- https://download.developer.apple.com/iOS/iOS_Logs/HealthKit_Logging_Instructions.pdf

- https://download.developer.apple.com/iOS/watchOS_Logs/HealthKit_Logging_Instructions__Watch.pdf

and attaching the resulting logs to a bug report here : https://feedbackassistant.apple.com

I think the only option is to do a full reset after wiping all data. I backed up my phone to iCloud and then did a full reset.The issue is resolved and battery is also draining.
