The Xiaomi Mi Smart Scale 2 works with the Mi Fit (or Zepp Life) app to track individual users’ body metrics such as weight, BMI, body fat, and muscle mass.
To ensure that these measurements remain accurate, each user’s personal profile—including nickname, height, age, and gender—must be correct and up to date.
This guide will show you how to:
-
Change a user’s nickname (username).
-
Update height and age information.
-
Manage multiple family member profiles in the Mi Fit app.
Before You Begin
Make sure that:
-
Your Xiaomi Mi Smart Scale 2 is paired with the Mi Fit (or Zepp Life) app.
-
Bluetooth is enabled on your smartphone.
-
The app is updated to the latest version.
-
The user you want to modify already exists in your family member list.
⚠️ Note: Inaccurate height or age data can affect BMI, body fat percentage, and other analysis results. Always ensure these values reflect real, current information.
Step-by-Step Instructions
Step 1: Open the Mi Fit App
-
Launch the Mi Fit app (also known as Zepp Life) on your smartphone.
-
Make sure the Mi Smart Scale 2 is connected — you should see the latest weight result displayed on the home screen.
Step 2: Access the Weight Results Page
-
Tap on your current weight measurement shown on the main screen.
-
This will open the detailed weight analysis page, where you can view all your recorded metrics such as BMI, body fat percentage, and weight trends over time.
Step 3: Open the User Management Menu
-
On the top-right or bottom section of the weight analysis page (depending on your app version), look for a “+” (Plus Icon) or “Manage Members” option.
-
Tap the Plus Icon to enter the user management or member settings section.
Step 4: Select the User Profile to Edit
-
You will see a list of all users associated with your Mi Smart Scale 2—for example:
-
You (Main User)
-
Family Member 1
-
Guest Account
-
-
Tap on the name of the member whose information you want to change.
Step 5: Edit the User Information
Once you’ve opened the user’s profile, you can modify the following fields:
-
Nickname (Username):
Enter a new name to easily identify this user’s measurements. -
Height:
Input the correct height (in centimeters). The app uses this value to calculate BMI and other body composition metrics. -
Age / Date of Birth:
Adjust the user’s birth year to update their current age automatically. -
Gender (optional):
Verify that gender information is correct, as it influences muscle, fat, and bone mass calculations.
✅ Tip: If you are updating information for multiple family members, edit and save each profile one by one to avoid overwriting data.
Step 6: Save Changes
-
After editing, tap Save (or Confirm) at the bottom of the screen.
-
Wait a few seconds until the app updates the profile data.
-
The new height, age, and nickname will now be reflected in all future measurements.
Step 7: Verify the Update
-
Return to the main screen of the Mi Fit app.
-
Step on the Mi Smart Scale 2 again to take a new measurement.
-
Confirm that the reading appears under the correct, updated username with the new profile details.
Why Updating Profile Data Matters
Accurate personal data is crucial for reliable analysis.
| Parameter | Impact on Measurement |
|---|---|
| Height | Affects BMI and proportional calculations |
| Age | Influences body fat estimation and metabolic rate |
| Gender | Determines fat-to-muscle ratio modeling |
| Nickname | Helps distinguish multiple users on the same device |
If height or age are entered incorrectly, your BMI or body composition results may be significantly inaccurate.
Troubleshooting
| Issue | Cause | Solution |
|---|---|---|
| Can’t find “+” icon | App version outdated | Update the Mi Fit app to the latest version |
| Changes not saving | App sync error | Log out and back in, then retry |
| Wrong user data appears | Scale is auto-detecting another user | Delete duplicate profiles and reassign weight data manually |
Additional Tips
-
For multi-user households, create a unique nickname for each person to prevent mix-ups.
-
Periodically review and update height and age (especially for growing children).
-
If you switch phones or reinstall the app, log in with the same Xiaomi account to retain your saved profiles.
