Distance and step tracking

[Highhorse3]

I have had the Sense 2 for a week and the distance and step tracking has never been even close to correct. I walk 2.5 miles a day and it has tracked 1.2, 1.4, but never even close to what i actually walk. And my steps are about 1500 short when completed as well. I have manually calibrated my stride, but what else can be done. With GPS, this shouldn’t be an issue, right?

@Highhorse3 , A warm welcome to the Community! Thank you for your message and information. 

The distance is calculated by multiplying the amount of steps with the stride length. The GPS helps with the accuracy. 

As you mentioned that you see around 1500 less, then this is why the distance is not correct. 

I'm going to address the step issue first, looking to solve this and with it solve the issue with the distance. 

Please answer these questions that will help me determine where the issue comes from.:

• The missing steps are shown/ deducted after you synchronize the Sense 2 with the app or on the watch itself during the activity? ( eg. on the Sense 2 before sync, 1600 steps after sync only 100 in the app or on the Sense 2 there are always the 100?)
• Does this happen with a specific activity or with many different ones? ( just with Running , or also with walking, hiking, etc)

In the meantime, charge the Sense 2 for at least 30 minutes .
Press and hold the button for 10 seconds until the Fitbit logo appears on the screen, and then release the button. The watch should restart afterwards. 

Also try to change the stride length , Can I change my stride length in my Fitbit account?

I also would recommend to try using the watch a bit looser or tighter, higher or lower on the wrist, to see if this helps to recognize all the steps. How do I wear my Fitbit device?
