Charge 3 step count inaccurate

[KirbieG]

I have been using a Fitbit One for several years and it seemed to be pretty accurate in step counts. I switched to the Charge 3 and it doesn’t seem to be registering all my steps. I put my Fitbit One on as well today and it has over 3,000 more steps on it. How do I make sure my Charge 3 is counting all my steps?

Welcome to the Community, @KirbieG.

For tips about improving accuracy, I recommend checking the help article: How accurate are Fitbit devices?.

Several things can affect the number of steps your Fitbit device records, including where you place the device, if you wear it on your dominant or non-dominant hand, and your stride length. If you're pushing a stroller or shopping cart, try putting your device in your pocket or use GPS to record your activity, if possible.

If it still seems like your device is undercounting or overcounting steps, try a step test. While you perform your step test, make sure you:
-Walk at a normal pace
-Don’t hold anything in your hands
-Put your arms down at your sides, swinging naturally
-Count 1 step for each foot
-To avoid getting an additional step when you bring your feet together, after you reach 100 steps:
1. Freeze in a split-stance. 
2. Move your hand up gently to check the step count on your device.  

Here’s the step test:
1. Restart your Fitbit device. For instructions, check the help article: How do I restart my Fitbit device?.
2. Put your device on your wrist.
3. Walk 100 steps, making sure to count a step each time one of your feet touches the ground.
4. Pause, then check your device to see your step count, and write down the number of steps you took and the number of steps your device counted. 
5. Perform the test 2 more times, walking 100 steps 3 different times. Each time, write down the number of steps you took and the number your device counted. 
6. Add the number of steps over or under that your device counted for all 3 tests. If your device counted 30 more or 30 fewer than the 300 steps you took, please let us know. 

I will see you around. 🙂
