Health app

I recently switched to the Iphone 13 pro from Iphone 11 pro, and finding that the health app is understating the mileage covered, but as much as .5 mile on a 3 mile walk (which is fairly significant). Can I do anything to improve the tracking?

iPhone 13 Pro, iOS 15

See the "Make sure that you earn Move and Exercise credit" section in:

You should also make sure your watch is calibrated:

The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup just created. This should result in no loss of data. It deletes all temp and corrupted files and re-indexes the file system.
