How to tie Xiaomi scales to the phone: instructions with photos and error solutions

Xiaomi’s smart scales are no longer just a weight measurement device — they analyze body composition, track changes, and sync data with mobile apps — but to make all these functions work, you need to properly tie the scales to your smartphone, and in practice, users face connection errors, compatibility issues, or simply don’t know where to start.

In this article, we will discuss all the ways to synchronize the scales Xiaomi Mi Smart Scale 2, Xiaomi Body Composition Scale, Mi Body Composition Scale 2 and other models with phones on Android and iOS. You will learn how to prepare devices, which applications to use (Mi Fit, Zepp Life, Apple Health), and what to do if the scales are not connected or permanently disabled. At the end, you will find an FAQ with answers to frequent questions and a model compatibility table.

What Xiaomi scales can be connected to the phone?

Xiaomi has released several generations of smart scales, all of which support synchronization with smartphones, and here are the main models that are relevant in 2026:

• 📱 Mi Smart Scale 2 is a basic model with weight, BMI, fat and muscle mass measurements. Works via Bluetooth 4.0.
• 📊 Xiaomi Body Composition Scale – Extended version with analysis of 13 body parameters (including bone mass and water level).
• 🔋 Mi Body Composition Scale 2 - Improved accuracy, Wi-Fi support for automatic synchronization.
• 👶 Xiaomi Baby Scale - a specialized model for weighing babies (up to 20 kg).

All of these devices connect via the official Mi Fit (obsolete) or Zepp Life (current in 2026) apps, except for the Mi Body Composition Scale 2, which also supports direct sync with Apple Health and Google Fit.

⚠️ Xiaomi scales do not work with phones that are disabled Bluetooth or lack support for Bluetooth Low Energy (BLE). Before buying, check if your smartphone supports BLE (Most of the models after 2016 are yes).

Preparing for connection: what to do before synchronization

Before you tie the scale to the phone, follow a few mandatory steps:

1. Charging scales. Most Xiaomi models run on 4 AAA batteries. Make sure they are installed correctly (observe polarity!). In models with a battery (Mi Body Composition Scale 2), check the charge level through the app.
2. Download Zepp Life (formerly Mi Fit) from Google Play or the App Store. The older version of Mi Fit is not recommended for use, it doesn't support new scale models.
3. Register with Zepp Life via email, phone number or Xiaomi/Google/Apple account.
4. Turn on Bluetooth. On your phone, activate Bluetooth and allow the Zepp Life app to use it (in the app resolution settings).

If you’ve used Xiaomi scales before and now want to connect them to a new phone, untie the device in the old app first.

1. Open Zepp Life → Go to Profile → My Devices
2. Choose the scales → press ⚙️ Settings → Remove the device.

Step-by-step: how to tie the scales Xiaomi to the phone

The connection process is the same for most models, but there are nuances depending on the operating system. Let's look at both.

📱 Connection to Android

Follow this guide if you have a smartphone running Android 8.0 or later:

1. Open the Zepp Life app. Click on the + icon in the upper right corner.
2. Select Libra. In the list, find your model (e.g. Mi Smart Scale 2).
3. Press "Connect." The app will request Bluetooth and location access (required to allow!).
4. Stand on the scale. Wait for the scale to show the CON (connection) or the flashing Bluetooth indicator.
5. Confirm the connection in the application. The phone will notify you of the device found — click Connect.

If the connection is successful, the scales will sound, and the app will display your weight and basic body parameters, and the data will automatically be stored in profile.

🍎 Connection to iPhone (iOS)

For iPhone owners, the process is almost identical, but there are a couple of features:

1. In Zepp Life, click + → Libra and select your model.
2. When the app asks for Bluetooth to be enabled, allow access. iOS 17+ may also require permission to notify.
3. On an iPhone, it can take up to 30 seconds to connect - don't take your feet off the platform!
4. Once synced, the data will appear in the app. To export it to Apple Health, go to Profile → Settings → Sync with Apple Health and enable the desired settings.

Important: On iPhone, Xiaomi scales won’t appear in the standard Bluetooth menu (Settings) and they only connect via Zepp Life!

Solution: Xiaomi scales do not connect to the phone

Even with the right actions, synchronization may not work, and here are the most common mistakes and ways to fix them:

If none of the methods helped, try to lose weight to factory settings:

1. Turn off the scales (remove the batteries).
2. Press the on button (if any) or insert the batteries while holding any button for 10 seconds.
3. After resetting, reconnect the scales as when you first use them.

⚠️ Note: If Xiaomi scales are plugged in but show the wrong weight (e.g., the wrong weight, +10 kg), the problem may be in the wrong calibration. Put the scales on a flat hard surface (not on the carpet!) and perform the calibration manually: stand on the scale, then take off your legs and wait for zero.

How to set up automatic data synchronization

By default, Xiaomi scales only transmit data to Zepp Life during weighing, but you can set up automatic export to other services:

• 📱 Google Fit (Android): Open Zepp Life → Profile → Settings → Accounts and syncs. Select Google Fit and log in to your Google account. Allow access to weight, height and body composition data.

Apple Health (iOS):

1. In Zepp Life, go to Profile → Settings → Sync with Apple Health.
2. Turn on the switches opposite the parameters you want to export (weight, % fat, etc.).

Cloud synchronization:

Settings → The Cloud

If you use the Mi Body Composition Scale 2 with Wi-Fi support, you can set up automatic data download without your phone:

1. Connect the scale to a 2.4 GHz Wi-Fi network (not 5 GHz!).
2. In the Zepp Life app, go to the scales settings and select your network.
3. Enter the Wi-Fi password. Once connected, the scales will send data to the cloud automatically.

💡

If you have multiple users in your family, Zepp Life can create profiles for each family member. Go to Profile → Family Management and add new users. The scale will automatically recognize who has joined them by weight (with an error of ± 2 kg).

Update of the firmware of Xiaomi scales

The manufacturer regularly releases firmware updates for the scales, which improve the accuracy of the sensors and add new features.

1. Open Zepp Life and go to the section with your weights.
2. Click on the icon. ⚙️ Settings → Firmware update.
3. If a new version is available, click Update and wait for the process to complete (don’t remove the scales from charging!).

During the update:

• 🔋 Libras must be at least 50% charged (or connected to the network).
• 📶 Make sure your phone is connected to stable Wi-Fi (update over the air can weigh up to 10MB).
• ⏳ If the update is stalled, reset the scales (remove the batteries for 10 seconds) and try again.

⚠️ Note: After updating the firmware, Xiaomi scales may reset settings (such as user profiles!

💡

Xiaomi’s firmware update takes 2-5 minutes. If it lasts longer than 10 minutes, interrupt and try again. Most often, hangings are associated with unstable Internet or low battery power.
