Health App using 1.61TB of storage on iOS 14

Howdy, HZ1YR!

We understand that you're seeing your Health app take up an unusual amount of storage.

To start with, confirm for us that you are running iOS 14.1 or later and if you have an Apple Watch, watchOS 7.0.2 or later. 

• iPhone: Go to Settings > General, then tap About.
• Apple Watch: You can find this out on your Apple Watch at Settings > General > About or on your iPhone by opening the Watch app and then tapping Settings > General > About.

However, if you're still having the issue after updating to the latest version of OS we recommend that you try the following steps to address your storage issue: 

• If you have an Apple Watch, please Unpair and erase your Apple Watch. Keep Unpairing the watch erases it and triggers a backup. For GPS + Cellular models, choose to keep the cellular plan when prompted.
• On iPhone, go to Settings > [your name] > iCloud. Turn Health on if it isn't already on.
• Tap Settings > [your name] > iCloud > iCloud Backup. Ask the customer to tap “Back Up Now.” Wait for the data to back up.
• If you can't restore it using iCloud, you can try restoring it from an encrypted iTunes backup that was taken from a device running iOS 13. A non-encrypted iTunes or local backup resolves the issue, but previous health data will be lost.
• Verify that you have a backup, which you can do by opening the Health app on the iPhone, tap Profile from the top right. At the very bottom of the screen, it should say: "Health data was last backed up at..."
• If the time listed isn't recent, wait for the backup to complete. Then check the Health app again to verify that you have a recent backup.
• Erase all content and settings from the iPhone. Go to Settings > General > Reset. Tap Erase All Content and Settings.
• When the iPhone restarts, you get the option to set up as new or restore from a backup. You can choose to restore from an iCloud backup, restore from an encrypted local backup from iOS 13, or set up as new. 
• After the iPhone has been restored, you can pair your Apple Watch again if you have one.

After you have completed all these steps, make sure to keep your software up to date.

Let us know if this helps with your issue,

Cheers!
