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.

Hmmm. Seems like a lot. I didn’t have the issue when I first set up my phone and watch. Then I noticed the watch wasn’t recording data. Unpaired and paired the watch. The watch started working normally and then I got the issues we are seeing. I have my phone turned off right not to compare usage in the morning and see if it helps. Also, turned off health and other things. Deleted a bunch of health data as well as I wasn’t near your type of streak ;)


hoping they acknowledge an issue.

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.
