How to connect Xiaomi Mi Body Composition Scale 2 smart scales to your phone: instructions for 2026

Introduction: Why Smart Scales Are Needed and How They Work With Your Phone

The Xiaomi Mi Body Composition Scale 2 is not just a weight measurement device, it's a full body composition analyzer. It defines 13 key parameters, from body mass index (BMI) to visceral fat and muscle mass. But all of this functionality is revealed only when synchronized with a mobile application. Without a phone connection, you will get only basic weight readings - like on a conventional mechanical scale.

The main advantage of the model is accurate biometrics due to 4 electrodes and artificial intelligence algorithms. However, many users face problems when connecting first: scales are not in the application, data is not synchronized, or errors such as “Device is not responding.” In this article, we will discuss the current 2026 pairing algorithm, consider the features of work with iOS and Android, and give recommendations for solving typical problems.

The Mi Body Composition Scale 2 features two ecosystems: the original Mi Fit app (now Zepp Life) and third-party platforms like Apple Health or Google Fit, which means you can integrate data into your existing services for comprehensive health monitoring, but you need to do the right setup first.

What you need to connect: full checklist

Before you start pairing, make sure you have everything you need, and missing at least one item from the list can cause you to crash.

• 📱 Smartphone on Android 6.0+ or iOS 12.0+ Bluetooth 4.2 support (or newer)
• 🔋 Xiaomi Mi Body Composition Scale 2 with a battery charge of at least 20% (at a discharge below this threshold, synchronization is blocked)
• 🌐 Sustainable Internet connection (Wi-Fi or mobile network) for downloading the application and updating the firmware of the scales
• 📲 The latest version of the Zepp Life app (formerly Mi Fit) downloaded from the official store (App Store or Google Play)
• 🆔 Xiaomi or Zepp account (can be created directly in the app)

Important: If you use an iPhone, pre-check the permissions for the Zepp Life app in the privacy settings. On Android, make sure that Bluetooth power saving modes are turned off - they can interrupt the connection to the scales. It's also worth uninstalling older versions of Mi Fit if they're installed to avoid conflicts.

Note regional restrictions: in some countries (e.g. the U.S.), Zepp Life may require a VPN to work properly, due to Xiaomi’s server allocation policy. If you have problems logging in, try changing your phone settings to China or Russia.

Step-by-step instructions: how to connect the scales to the phone

The pairing process takes no more than 5 minutes, if you follow the algorithm, and we break it down into steps with detailed explanations for each step.

1. Download Zepp Life from the official store. Avoid third-party sources, it can cause viruses and malfunction. Once installed, open the app and register (or log in to an existing account). Use the same email as other Xiaomi devices, if you have them, it will make it easier to sync your data.
2. Activate the scales Turn the scales on by pressing the touch button or simply by standing on the platform. The Bluetooth symbol (stylized letter "B") should appear on the screen. If the indicator is not on, check the battery power - it may be necessary to replace the batteries (4 AAA batteries).
3. Adding a device in the app In Zepp Life, go to Profile → Add Device → Libra. Select the Mi Body Composition Scale 2 model. The app will automatically start searching for available devices. Make sure the scales are no more than 1 meter away from the phone - otherwise the Bluetooth signal may be too weak.
4. When the scales appear on the list, click on them to connect. Wait for the sound signal and vibrations, which means successful pairing. Then the application will suggest calibrating: stand on the scale with bare feet (electrodes must touch bare feet) and hold the position for 5-7 seconds. Do not move at this moment - this will distort the readings.
5. After calibrating, fill in your personal data: gender, age, height and activity level, which determines your BMI, ideal weight and other metrics. If you have already used other Xiaomi devices (such as the Mi Band bracelet), the data can be imported automatically.

Now, every time you weigh in, you're automatically going to send data to the app, and the first synchronization can take up to 30 seconds, which is normal, and then it's going to take 2-3 seconds.

💡

If the scales do not respond to touch, wipe the electrodes with an alcohol napkin - fat or sweat can block the sensors.

Common Mistakes and How to Fix Them

Even with the exact following of the instructions, there are sometimes failures, and we have collected the TOP-5 problems and ways to solve them, based on user feedback and recommendations from Xiaomi support.

If none of these things worked, try to lose weight to factory settings.

1. Turn off the scales (hold the button for 10 seconds).
2. Turn them on by holding the button until it appears on the screen. --:--.
3. Release the button and the scales will reset and be ready for a new connection.

Compatibility with iOS and Android: key differences

While the Mi Body Composition Scale 2 officially supports both platforms, there are nuances to be aware of in advance.

Features of working with iPhone (iOS)

• 🍎 Zepp Life app may request access to Apple Health – allow sync so data is automatically transferred to a standard health app.
• 🔄 On iOS, the firmware update of the scales is in the background and can take up to 10 minutes.
• 🛑 In some regions (e.g. the EU) due to restrictions GDPR Additional confirmation is required to collect biometric data.

Features of working with Android

• 🤖 On Xiaomi, Redmi or phones POCO The Zepp Life app can be pre-installed. Update it to the latest version.
• 🔋 Android is more aggressive in optimizing background processes. Add Zepp Life to the power saving exception list (Settings) → Battery → Optimizing the battery).
• 📱 On some firmware (for example, MIUI 14) manually allow the application to auto-run for stable synchronization.

Important: If you use Huawei without Google services, download Zepp Life via AppGallery.The third-party version may not support weight sync.

How to improve measurement accuracy: tips from experts

The Mi Body Composition Scale 2 has a margin of error of ±50 grams for weight and ±3% for other metrics, but these are only valid if the measurement conditions are met.

1. It is best to weigh yourself in the morning on an empty stomach, after going to the toilet. In the evening, the weight can vary by 1-2 kg due to the fluid and food consumed.
2. Use scales only on a solid, flat surface (tile, laminate). Carpets or soft coatings distort readings due to uneven load distribution.
3. Stand still, spreading the weight evenly on both legs. Don't lean on the wall or furniture - it affects the calculation of body composition.
4. The level of water in the body affects the readings of fat and muscle mass. For accurate data, avoid weighing immediately after exercise or heavy drinking.
5. Calibration Once a month, do a manual calibration: stand on the scale and hold the position for 10 seconds. This will reset the accumulated sensor errors.

Fun fact: Xiaomi scales use Bioelectrical Impedance Analysis (BIA) technology, low-intensity current flows through the body, and resistance calculates the composition of tissues, so wet or sweaty feet can distort the results by 5-10%.

💡

For maximum accuracy, always weigh yourself at the same time of day, in the same clothes (or without them), and in the same place.

Integration with other services: Apple Health, Google Fit, Strava

One of the key benefits of the Mi Body Composition Scale 2 is the ability to export data to third-party applications, which allows you to create a single ecosystem for health monitoring, and let's look at how to configure synchronization with popular services.

Sync with Apple Health (for iOS)

1. Open Zepp Life and go to Profile → Settings → Accounts and Sync.
2. Select Apple Health and switch on the switch.
3. Allow access to all categories of data (weight, height, fat mass, etc.).
4. In the Health app on the iPhone, the data will appear in the Overview → Body Parameters section.

Sync with Google Fit (for Android)

1. In Zepp Life, go to Profile → Settings → Accounts and Sync → Google Fit.
2. Sign in to your Google account and confirm your permissions.
3. Choose which data to export (it is recommended to leave all ticks).
4. In the Google Fit app, the data will be available in the Log → Body Parameters section.

To sync with Strava, MyFitnessPal or Yazio, use an intermediate export via Google Fit or Apple Health.

1. Set up export from Zepp Life to Google Fit.
2. In MyFitnessPal, connect your Google Fit account in the integration settings.

Note that some apps (such as Samsung Health) may not support direct imports from Zepp Life, in which case use the.csv export files that you can get from the Zepp Life web version on your computer.
