Charge 5 incorrect steps and calories data

[StephN2024]

Hello, I just received a fitbit 5, so I could upgrade from my 4. however, I charged it and have not worn it. When I went to look at it and start wearing it, it said I had walked 6 steps and burned 3900 calories. This cannot be right. I then also apparently walked 20 more steps while sitting completely still. Is there a way to fix the data reading on this?

Welcome to the forums @StephN2024. 

Thank you for providing the details regarding steps and calories. 

Fitbit devices combine your basal metabolic rate (BMR)—the rate at which you burn calories at rest to maintain vital body functions (including breathing, blood circulation, and heartbeat)—and your activity data to estimate your calories burned. If your device tracks heart rate, your heart-rate data is also included, especially to estimate calories burned during exercise. The number you see on your Fitbit device is your total calories burned for the day.

Your BMR is based on the physical data you entered in to your Fitbit account (height, weight, sex, and age) and accounts for at least half the calories you burn in a day. Because your body burns calories even if you’re asleep or not moving, you see calories burned on your device when you wake up and will notice this number increase throughout the day.

Note that in certain regions, you see kilojoules instead of calories. To change your units of measurement, see How do I change the units of measurement in my Fitbit account?.

Regarding steps, keep in mind that excess vibration might cause extra steps. Fitbit devices have a finely-tuned algorithm for step counting. The algorithm is designed to look for intensity and motion patterns. When working at a desk, cooking, or performing other activities with arm movements, a device on your wrist may add some steps. When you’re doing activities that involve arm movement you often walk a few steps in-between stationary periods as well, so the device tries to give you credit for those steps. 

In order to have a better count of steps I'd suggest to confirm that the following data is correct in the Fitbit app:

• Your wrist settings (For more information, see Does the wrist I wear my device on affect accuracy? )
• Your height (For more information, see How do I manage my Fitbit profile?)

Since we use height to estimate your walking and running stride lengths, you may want to measure and manually adjust these values if your legs are longer or shorter than average. For more information, see How does my Fitbit device calculate my daily activity?
