Erratic calories and steps

[KirstyEllie]

My fitbit in the last week has started "making up" steps taken and calories burned that don't add up. Yesterday morning it randomly started my day with 8000 steps. The calories displayed on the home screen as burned also don't match the calories burned when I open up the chart. I've tried resetting it, disconnecting and reconnecting etc. Is it just broken now? I've had it for about 16 months

@KirstyEllie Welcome to the Fitbit Community! I hope you're doing well!

Let me help you with your recording steps and calories on your Charge 2. This is odd although I would like to explain that your device will detect the movement on your arm and translate that movement into steps. There are situations in which your arm may move but you won't be actually walking. For example, this may happen when you are playing the drums, burping a baby or clapping. It can also happen when driving. You can negate these steps by logging a driving activity. You can try wearing your device on your non dominant hand but select that hand as dominant on the device’s settings to make it less sensitive to movement.

Let me know how it goes.

Hi, this isn't happening while I'm wearing the fitbit, it happens overnight
while it is charging. It also adds random calories that don't match the
enlarged chart of calories burned in the day.
