Xiaomi’s smart scales are not just a weight measurement tool, but a full-fledged analytical tool that helps track body dynamics, fat levels, muscle mass and even metabolism. However, to access all these features, you need to connect the device correctly to your smartphone. Many users face difficulties at this stage: the scales are not in the application, the data is not synchronized, or errors like “The device does not respond.”
In this article, we will analyze the step-by-step connection algorithm for all current Xiaomi scale models (including Mi Body Composition Scale 2, Smart Scale 2 and Mi Scale), consider the nuances of working with Mi Fit and Zepp Life applications, and give recommendations for eliminating typical problems.
What Xiaomi scale models support phone connection
Xiaomi has several lines of smart scales that are functional and design-driven, all connected to a Bluetooth Low Energy (BLE) smartphone, but have their own synchronization features. Here are the current models for 2026:
- 📱 Xiaomi Mi Body Composition Scale 2 is a flagship model with an analysis of 13 body parameters (including visceral fat and bone mass). Supports up to 16 user profiles.
- 📱 Xiaomi Smart Scale 2 is a budget option with basic metrics (weight, BMI, fat/muscle mass). Works only with Mi Fit.
- 📱 Xiaomi Mi Scale (first generation) is an outdated model, but still available. Requires manual addition to Mi Fit.
- 📱 Xiaomi Mi Body Fat Scale is a specialized version for athletes with advanced muscle mass analytics.
Important: scales without a display (for example, Mi Scale Basic) are synchronized exclusively through the application - only weight is displayed on the scales themselves, and the rest of the data (fat percentage, water in the body) is available only in Mi Fit/Zepp Life.
Before buying, check the compatibility of the model with your smartphone. For example, Mi Body Composition Scale 2 requires Android 6.0+ or iOS 12.0+, and for Smart Scale 2, Android 5.0 is enough. Detailed requirements are specified in the specifications on the Xiaomi website.
Preparing for connection: what to do before synchronization
To avoid connection errors, follow a few preliminary steps, which will save time and eliminate the need to reconnect the device.
Install the Mi Fit or Zepp Life app
Charge the scales (if the model with a battery)
Turn on Bluetooth on your smartphone
Make sure the scales are on a level surface.
Prepare data for the profile (height, age, gender)-->
Installation of the annex
Xiaomi scales work through branded applications:
- 📲 Mi Fit is the official app for all scales, and it supports synchronization with Google Fit and Apple Health.
- 📲 Zepp Life (formerly Mi Fit for overseas market) is an advanced analytics alternative, and some models (such as the Mi Body Composition Scale 2) work better with this application.
Download the current version from the official stores:
- 🤖 Mi Fit for Android
- 🍎 Mi Fit for iOS
- 🌍 Zepp Life (international version)
2. Checking the compatibility of the smartphone
Xiaomi's smart scales require Bluetooth 4.0+ support. Outdated phone models (such as those with Android 4.x or iOS 10 and below) may not detect the device.
- On Android: go to Settings → About Phone → Bluetooth version.
- On iPhone: All models starting with the iPhone 4S support BLE, but iOS 12+ is recommended for stable operation.
💡
If your smartphone can’t see the scales, try turning off battery savings for the Mi Fit/Zepp Life app in your Android settings. On your iPhone, check that the app is allowed Bluetooth access in Settings → Privacy → Bluetooth
Step-by-step: how to connect Xiaomi scales to the phone
The connection process takes no more than 5 minutes, if you follow the algorithm, below is a universal guide for all Xiaomi scale models (taking into account the nuances for specific devices).
Step 1. Turn on the scales and prepare them for synchronization
Most Xiaomi models are activated automatically when they are first turned on.
- Set the scales on a flat, hard surface (not on a carpet!).
- Press the scale platform with one finger – the display (or connection indicator) should light up.
- If the scales are battery-powered (like Smart Scale 2), make sure the batteries are installed correctly (polarity!).

Step 2. Add the device to the app
Open Mi Fit or Zepp Life and do the following:
- Click on the Profile icon → Add the device (in Mi Fit) or Devices → Add (in Zepp Life).
- Choose the Libra category or Smart Scale category.
- Click Connect and wait for the app to find your scales. If the device is not detected, click Manual and select the model from the list.
Step 3: Set up a user profile
For accurate measurements, Xiaomi scales require user data:
- 📏 Growth (in cm) - affects the calculation of BMI.
- 👶 Age is important for analysis of metabolism.
- ♂️/♀️ Sex determines the fat/muscle mass.
- 🏃 Activity level (in Zepp Life) is Sedentary, Moderate, or Active.
⚠️ Warning: If you specify the wrong height, the scales will show an incorrect percentage of fat. For example, with a height of 170 cm and a weight of 70 kg, BMI will be 24.2, and with an mistaken growth of 160 cm, it will already be 27.3 (pre-obesity).
Step 4: Take the first measurement
After synchronization:
- Stand on the scales with bare feet (socks distort impedansometry readings).
- Spread the weight evenly on both legs.
- Wait for the stabilization of the readings (on the display will appear a tick or the inscription OK).
- The data will automatically be sent to the app. If sync does not occur, update the page manually (pull the screen down).
💡
For accurate analysis of body composition, measure at the same time of day (preferably in the morning on an empty stomach) and under the same conditions (for example, after the toilet, but before breakfast).
Table: Comparison of Mi Fit and Zepp Life
Both apps support Xiaomi scales, but have different functionality, and below is a comparison table to help you choose:
| Function | Mi Fit | Zepp Life |
|---|---|---|
| Sync with Google Fit/Apple Health | ✅ Yes. | ✅ Yes. |
| Trend analysis (weight, fat, muscles) | ✅ Basic | ✅ Extended (with forecasts) |
| Support for Multiple Users | ✅ Up to 16 profiles | ✅ Up to 8 profiles |
| Exporting data to CSV/Excel | ❌ No. | ✅ Yes (in the premium version) |
| Nutrition/training recommendations | ❌ General advice only | ✅ Personalized (data-based) |
If you want detailed analytics, choose Zepp Life. Mi Fit is enough for basic use. Note: some weight models (e.g. Mi Body Composition Scale 2) in Zepp Life show additional metrics not available in Mi Fit (e.g., protein levels in the body).
Typical Connection Errors and How to Fix Them
Even if you follow the instructions correctly, users face problems, and let's look at the most common mistakes and how to fix them.
1.The scales are not in the annex
Causes and solutions:
- 🔋 Batteries/battery discharged – replace the batteries or charge the scales (for USB-Type C models).
- 📱 Bluetooth is disabled or faulty – check your smartphone settings, restart the Bluetooth module (in Settings → Bluetooth → Restart on Android).
- 🔄 Conflict with other devices – disconnect from your phone other gadgets (fitness bracelets, headphones) and repeat the search.
- 📲 An outdated version of the app — Update Mi Fit/Zepp Life to Google Play or the App Store.
2. data is not synchronized with the application
If the scales show the weight on the display, but the data is not sent to the phone:
- 🔄 Reset the scales: Remove and reset the batteries (or hold the 5 second reset button for battery models).
- 📱 In the app, click Update Data (circle arrow icon).
- 🚫 Remove the scales from the list of devices in the app and add again.
⚠️ Warning: If you’re using a dual SIM- card on Android, try turning one of them off — some phones limit Bluetooth when two SIMs are active.
3. Libra shows incorrect data (weight, percentage of fat)
Measurement errors arise from:
- 🧦 Socks or shoes - measure bare feet.
- 💦 Wet feet - wipe your feet before weighing.
- 📉 Uneven surface – scales should be placed on a hard floor (not on a carpet!).
- 👨👩👧 Incorrect Profile – Check height, age and gender in the app settings.
