Xiaomi’s smart scales are no longer just a weight measurement device, but today they are full-fledged fitness trackers that can analyze body composition, sync with mobile apps and even integrate into the Mi Home ecosystem. But how not to get lost in the variety of models and choose the scales that are perfect for you?
In this article, we will analyze all the current Xiaomi smart scale models (including the Mi and Xiaomi Smart brands), compare their technical characteristics, identify key differences and help determine the choice. We will focus on measurement accuracy, body analysis functionality and compatibility with popular fitness applications.
Spoiler: If you want a scale with maximum accuracy and Wi-Fi support (not just Bluetooth), then the Xiaomi Smart Scale 3 is the best choice.
Why Xiaomi Smart Libra: 5 Key Benefits
Xiaomi has firmly established itself as a low-cost, high-quality smart tech brand, and its scales are no exception, combining cutting-edge technology with affordable pricing. Here's what you get when you choose Xiaomi's smart scales:
- 📱 Ecosystem integration: All scales are synchronized with the Mi Fit app (or Zepp Life for new models), allowing you to track change dynamics, set goals and analyze progress. Data can also be exported to Google Fit or Apple Health.
- 🔍 Advanced body composition analysis: In addition to weight, most models measure body fat percentage, muscle mass, body water, bone mass, and even viscosity (in top versions), which helps adjust training and nutrition.
- 👨👩👧👦 Multiplayer: The scales automatically recognize up to 16 users (depending on the model), saving the measurement history for each family member.
- 🔋 Long non-recharging operation: Thanks to energy-efficient sensors and batteries like CR2032 or AAA, scales can run for up to 12-18 months without replacing batteries.
- 💰 Optimal price/quality ratio: even Xiaomi flagship models are 2-3 times cheaper than their counterparts from Withings or Garmin, while not inferior to them in exactness.
But things aren’t going so well, and there are some downsides that are often overlooked in advertising, such as Xiaomi’s scales can overstate body fat by 2 to 5 percent compared to medical analyzers (independent tests confirm this), and some users complain of unstable synchronization with the app when Bluetooth is weak.
Top-5 models of Xiaomi smart scales in 2026 year: comparative table
To make it easier to choose, we put all the models in one table, and look at the Connection Type and Sensor Number columns, which determine the accuracy and functionality of the device.
| Model | Type of connection | Number of sensors | Max. Weight, kg. | Analysis of body composition | Price, ₽ (compare by market) |
|---|---|---|---|---|---|
| Xiaomi Mi Smart Scale 2 | Bluetooth 5.0 | 4 (BIA) | 150 | Weight, BMI, fat, muscle, water, bones | 1 900–2 400 |
| Xiaomi Mi Body Composition Scale 2 | Bluetooth 5.0 | 4 (BIA) | 150 | + viscosity, protein, basic metabolism | 2 500–3 200 |
| Xiaomi Smart Scale 3 | Bluetooth 5.0 + Wi-Fi | 8 (BIA) | 150 | + muscle tone, visceral fat, met. age | 3 500–4 200 |
| Xiaomi Smart Scale 2 Lite | Bluetooth 5.0 | 4 (BIA) | 150 | Weight, BMI, fat, muscle, water | 1 500–1 800 |
| Xiaomi Mi Body Fat Scale (Old) | Bluetooth 4.0 | 4 (BIA) | 150 | Weight, BMI, fat, muscle, water | 1 200–1 500 |
As you can see from the table, the Xiaomi Smart Scale 3 is the only Wi-Fi-enabled model that allows you to synchronize data without a smartphone (for example, if you forgot your phone in another room), and it is equipped with 8 sensors instead of the standard 4, which increases the accuracy of body composition analysis.
⚠️ Warning: If you plan to use scales for medical purposes (such as disease control), look for certification. Only the Mi Body Composition Scale 2 and Smart Scale 3 models have a medical certificate CE and FDA for body composition measurement.
Which model to choose: a detailed analysis of the objectives
The scales you choose depend on what you buy them for, so let's see which model is the right fit for each one.
1.For basic weight control and BMI
If you want a simple scale for daily weighing without bells and whistles, the Xiaomi Smart Scale 2 Lite model is enough. It measures weight, BMI and percentage of fat / muscle / water with acceptable accuracy.
- 💰 The lowest price among Xiaomi smart scales.
- 📏 Compact size and minimalist design.
- 🔋 Powers from 3 AAA batteries (easily replaced).
Cons: No viscosity and protein analysis, and no Wi-Fi support.
2. for a thorough analysis of body composition
If you are serious about fitness or health, look for the Xiaomi Mi Body Composition Scale 2. This model provides advanced metrics:
- 🧬 Body viscosity (metabolism indicator).
- 🥩 Protein level (important for athletes)
- 🔥 Basic metabolism (BMR).
The scales also support pregnancy mode (disables fat analysis) and have improved sensors for more accurate measurements.
💡
If you want maximum accuracy, weigh yourself on an empty stomach in the morning, after going to the toilet, which minimizes the error of the analysis of body composition.
3. For professional use
Xiaomi Smart Scale 3 is a top-end solution with 8 sensors and Wi-Fi support. It is suitable for those who:
- 🏋️ Is engaged in bodybuilding and needs a detailed analysis of muscle mass.
- 🩺 Controls visceral fat (important for diabetes prevention).
- 📊 Wants to export data to the cloud without being tied to a smartphone.
The only downside is the high price tag, but if you want the most accurate scales in Xiaomi’s medically certified range, it’s the best choice.
For families with children
For family use, Mi Body Composition Scale 2 is suitable thanks to:
- 👶 Mode for children (height and weight analysis without fat).
- 👨👩👧👦 Support up to 16 profiles.
- 📲 A handy mobile application with a measurement history.
💡
For children under 10 years of age, body composition analysis is useless (and even harmful due to errors), and it is better to choose a model with a child mode that takes into account only weight and height.
What to look for when buying: 7 critical points
Even the most advanced scales can be disappointing, if you do not take into account some nuances.
- Battery type: Models with CR2032 (such as Smart Scale 3) are harder to replace than models with AAA.
- Platform material: glass or tempered glass? The latter is stronger but more expensive.
- Application compatibility: Some scales only work with Mi Fit, others work with Apple Health or Google Fit.
- Maximum weight: If your weight is close to 150 kg, choose a model with a margin (for example, Smart Scale 3 can withstand up to 180 kg in real tests).
- Bluetooth quality: Cheap models can lose touch with your smartphone if it’s in another room.
- Guarantee and service: in Russia, the official guarantee on the scales Xiaomi gives only Mi Store.
- Russian firmware: some “gray” deliveries come with the Chinese version of the application.
⚠️ Warning: If you buy scales on AliExpress or Wildberries, check with the seller whether the firmware is adapted for Russia. Otherwise, you will have to manually change the region in the settings of the Mi Fit application, which can lead to crashes.

What if the weight is not the right weight?
Comparison with analogues: Xiaomi vs Withings vs Garmin
To see how good Xiaomi scales are, let’s compare them to the main competitors:
| Parameter | Xiaomi Smart Scale 3 | Withings Body Comp | Garmin Index S2 |
|---|---|---|---|
| Price, ₽ | 3 500–4 200 | 12 000–15 000 | 10 000–12 000 |
| Accuracy of body composition analysis | ±3–5% | ±1–2% | ±2–3% |
| Support for Wi-Fi | ✅ | ✅ | ❌ |
| Export of data | Mi Fit, Google Fit, Apple Health | Withings App, Apple Health, MyFitnessPal | Garmin Connect, Strava |
| Guarantee in Russia | 1 year (official sellers) | 2 years | 1 year |
As you can see, Xiaomi loses to competitors in exactness, but wins at a price of 3-4 times. If you do not need medical accuracy, Xiaomi scales are the best choice. If accuracy is critical (for example, for athletes or people with diseases), you should consider Withings.
Frequent problems and their solutions
Even the best weights have failures, and here are the most common problems and ways to fix them:
1. Libras are not included
Causes and solutions:
- 🔋 Batteries are discharged: replace them (even if they are new - they could run out during storage).
- 🔌 The contacts are oxidized: wipe them with a cotton swab soaked in alcohol.
- 🛠️ Firmware failure: Reset settings (press the power button for 10 seconds).
2. Incorrect weight readings
What to do:
- ⚖️ Put the scales on a flat, hard surface (not on a carpet!).
- 🧘 Weigh yourself at the same time (better in the morning).
- 📏 Check calibration: stand on a scale and compare readings with mechanical scales.
3. Not synchronized with the application
Decisions:
- 📱 Reinstall the Mi Fit or Zepp Life app.
- 🔄 Turn off and turn on Bluetooth again on your smartphone.
- 🌐 If you are using Smart Scale 3, check your Wi-Fi connection.
⚠️ Warning: If after all the manipulations, the scales still don't work, check them on another smartphone. If the problem remains, it's a marriage, and the device needs to be returned under warranty. At the Mi Store, the warranty period is 12 months, but only if you have a check.
