Charge 3 step count inaccurate

[Nuzzer]

My Charge 3 has suddenly in the last 2 weeks been tracking way more steps than I used to do, and I am not sure why? I haven't done more walking or exercise than normal, but on an average day at the office and no gym class I would do about 7,000 - 8,000 steps a day, now it says I am doing 11,000 - 13,000 a day.

With exercise I an easily do 15,000 - 18,000 a day which seems very strange, especially since for the past 4 years of tracking it hasn't been this much. I have not changed anything. I am happy my step count has gone up but I am just confused and concerned as now I am not sure it is was under counting before or is over counting now.

Welcome to the Community, @Nuzzer.

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.

Let me know the outcome.
