Charge 3 distance information inaccurate

[tweety256]

My Charge 3 is not tracking my miles correct. at this point i am at 15307 steps and it shows 6.18 miles. my miles should be over 7 miles at this point. this morning i did a 5 mile walk and my Fitbit was only showing 4 miles. how can i get this fixed. I have rebooted my Fitbit once and that helped for a short time. any help or advised would be appreciated

It's great to see you here, @tweety256.

Thanks for troubleshooting this distance issue. Fitbit devices calculate distance based on the device’s accelerometer data and stride length setting.

Default stride length is based on your height and gender. If available, Fitbit devices use GPS data to calculate more precise distances.When you sync your device, our algorithm interprets the data from the device, and you see your distance traveled in the Fitbit app. 

Note that when you track an exercise with GPS, both GPS and accelerometer data are used to calculate the distance shown in the Fitbit app. For more information about accuracy, check the article: How accurate are Fitbit devices?.

Let me know the outcome.
