Charge 5 GPS is not accurate

[Elonian]

The GPS on my Charge 5 is extremely inaccurate.  It adds about .25 mile for every mile.

Hi there, @Elonian. Welcome to the Fitbit Community Forums. Thanks for the details provided in your post about the issue with your Charge 5.

Please note when you track an activity with GPS, your device calculates your distance using GPS data rather than steps. If you begin moving before you get a GPS signal, your device calculates distance using your steps until GPS connects.

To update your stride length, track a run with GPS or measure your stride length manually. For more information, see Can I change my stride length in my Fitbit account?

My Charge 5 was connected to GPS before starting my walk. I've tried using
dynamic and built-in modes.
