Xiaomi’s smart scales are not just a weight measurement device, they’re a full-fledged health control assistant. They analyze body composition, sync data with mobile apps, and even integrate with fitness trackers. But to make all these functions work, you need to connect the device correctly to your smartphone. In this article, we’ll take a step-by-step guide for Mi Smart Scale 2, Mi Body Composition Scale 2, and other popular versions, and look at common bugs and ways to fix them.
The connection process takes no more than 5 minutes, but many users face difficulties: the scales are not in the application, the data is not synced, or the device is constantly disconnected. We will tell you how to avoid these problems and adjust the scales the first time, regardless of the model of your smartphone (Android or iOS).
What Xiaomi scales support phone connection
Not all Xiaomi smart scales are mobile compatible, here’s a current list of models that can be synced with a smartphone via the Mi Fit or Zepp Life app:
- 🔹 Mi Smart Scale 2 is the most popular model with an analysis of 13 body parameters (weight, BMI, muscle mass, etc.).
- 🔹 Mi Body Composition Scale 2 - improved version with high accuracy and support for Bluetooth 5.0.
- 🔹 Xiaomi Smart Scale (first generation) – basic model with weight measurement and BMI.
- 🔹 Xiaomi Mi Scale 3 – budget version with minimalist design.
- 🔹 Xiaomi Smart Scale 2 Lite – a simplified version without body composition analysis.
If your model is not included in this list, check its name on the box or in the documentation. Libras without Bluetooth support (for example, some of the models are not available in the box). OEM-You can’t connect to your phone, and pay attention to the region of purchase: devices purchased in China may require additional settings to work outside the country.
What you need to connect: preparing a smartphone and scales
Before you start syncing, make sure you have everything you need:
- 📱 Smartphone on Android 6.0+ or iOS 12.0+ Bluetooth-on.
- 🔋 Charged scales (if model with battery) or fresh batteries AAA (battery-powered).
- 📲 Installed Mi Fit (for older models) or Zepp Life (for newer models).
- 🌐 Stable Internet connection (only required for first setup).
Pay special attention to batteries: if the scales are not turned on or the indicator flashes, replace the batteries. For models with a battery (Mi Body Composition Scale 2), use the original USB-Type-C cable for charging. Charging from powerful adapters (for example, from a laptop) can damage the power controller!

Step-by-step: how to connect Xiaomi scales to the phone
Consider the universal algorithm for most models. If you have a Mi Smart Scale 2 or a Mi Body Composition Scale 2, follow these steps:
- Install the application: Download Mi Fit (for the Android/iOS) or Zepp Life (new models only) from official stores: 🤖 Mi Fit in Google Play 🍎 Mi Fit in the App Store
Register or enter.
Create a Xiaomi account (if not) or sign in via Google/Apple ID. Without authorization, data will not be synchronized.
Add the device.
In the app, click Profile → Add device → Libra. Select your model from the list. If it is not available, select Mi Smart Scale 2 (most scales are compatible with this firmware).
Activate the pairing mode
Stand on the scales, 0.00 or a flashing indicator should appear on the screen. If the scales do not respond, press the on button (if any) or knock on the platform.
Confirm the connection.
The app will prompt you to pair. Press Connect and wait for the synchronization to complete (usually takes 10–30 seconds).
Important: If the scales are not determined, try restarting your smartphone and repeating the process. On iPhone, it sometimes helps to turn off the "Continuous Bluetooth" function in the charge saving settings.
What to do if the scales are not connected?
Profile setting and weight calibration
After the connection, you need to configure a personal profile so that the scales correctly calculate the parameters of the body.
- Open the app and go to Profile → Devices → Your scales.
- Click Profile Settings and specify: 👤 Gender (male/female) 📏 Growth (in cm) 🎂 Age. 🏃♂️ Activity level (low/medium/high)
Save the changes and perform a test weigh.
If the data seems inaccurate (for example, fat percentage is overstated), calibrate:
- Stand on the scales with bare feet, evenly spreading the weight.
- Wait 5-10 seconds until the result appears on the screen.
- Repeat the weighting 2-3 times to average the data.
To activate these functions:
- Open the Mi Fit or Zepp Life app.
- Go to the weights section.
- Select the device settings and activate the desired options.
For example, to turn on the athlete mode (for people with high muscle mass), go to Profile → Additional settings → Athlete Mode. This will improve the accuracy of measurements for athletes.
💡
For maximum accuracy, weigh at the same time (preferably on an empty stomach in the morning), without clothes and bare feet. Avoid weighing after intense training or eating - this distorts the results.
