Choosing Xiaomi’s smart scales is a task that requires attention to detail. The brand offers several models with different functionality, from simple floor scales to advanced body composition analyzers. But how do you make the mistake of buying the model that will suit your goals? In this article, we will discuss the key parameters: measurement accuracy, compatibility with Mi Fit, design, maximum load and additional functions like analyzing muscle mass or water levels in the body.
It's important to understand that even Xiaomi's budget models are often superior to traditional mechanical scales, but if you want data not only on weight, but also on fat percentage, bone mass or metabolic age, you'll have to look at flagship devices. We tested popular models and made a rating based on price/quality ratio, so you don't have to overpay for unnecessary options.
Key criteria for choosing Xiaomi smart weights
Before you buy, determine what you need a scale for, if the goal is just to control weight, a basic model will do, and for athletes or health care professionals, body composition analysis and synchronization with fitness applications are important.
- 📏 Maximum load: most Xiaomi models can withstand up to 150-180 kg, but there are more durable options.
- ⚖️ Accuracy of measurements: error in budget models — ±100 g, premium - up to ±50g.
- 📱 Compatibility: All Xiaomi scales work with Mi Fit, but some also support Apple Health and Google Fit.
- 🔋 Type of power: batteries AAA Or built-in battery (rarely encountered).
- 📊 Additional metrics: fat percentage, muscle mass, water level, metabolic age, etc.
Pay special attention to the platform material. Glass scales look stylish, but can be slippery on wet surfaces. Plastic models are cheaper but less durable. Also check if they include rubber legs, which prevent slipping and protect the floor from scratches.
Top.-5 Xiaomi weight models: comparison of characteristics
We have selected the most popular Xiaomi scales available in 2026, and the chart below shows the key parameters that will help you compare them. Note the Additional Features column: they often justify the difference in price.
| Model | Max, load. | The margin of error | Additional functions | Price (exemplary) |
|---|---|---|---|---|
| Xiaomi Mi Smart Scale 2 | 150 kg | ± 100 g | Weight, BMI, synchronization with Mi Fit | 1,500 ₽ |
| Xiaomi Mi Body Composition Scale 2 | 150 kg | ±50 g | 13 metrics (fat, muscles, water, bone mass, etc.) | 2,500 ₽ |
| Xiaomi Smart Scale 2 (Black) | 150 kg | ± 100 g | Weight, BMI, black, anti-slip coating | 1,800 ₽ |
| Xiaomi Mi Body Fat Scale | 150 kg | ± 100 g | Fat, muscle, water analysis (9 metrics) | 2,200 ₽ |
| Xiaomi Mi Smart Scale (1st Gen) | 150 kg | ± 150 g | Weight only, base model | from 1,200 ₽ |
Important: models with body composition analysis (e.g. Mi Body Composition Scale 2) require you to enter accurate height, age and gender data in the Mi Fit app. Without this, fat and muscle indicators will be inaccurate!
⚠️ Note: If you use a pacemaker or other medical device, consult your doctor before buying a scale with a body composition analysis.
Xiaomi Mi Smart Scale 2 vs Mi Body Composition Scale 2: Which is Better?
These are the two most popular models, and they are often compared. Mi Smart Scale 2 is a budget option for those who only need weight and BMI. It is suitable for daily monitoring, but does not give information about muscle mass or water level. Mi Body Composition Scale 2, in contrast, offers 13 metrics, including metabolic age and blood viscosity (according to the manufacturer).
Price difference between models – about 1,000 ₽. Should you overpay? It depends on your goals:
- 🏋️ For athletes: Mi Body Composition Scale 2 is definitely better – it tracks the dynamics of muscle mass and fat.
- 🩺 Health Control: An advanced model can help track water levels and bone mass, which is important when dieting or recovering from injuries.
- ⚖️ For easy weighing: Mi Smart Scale 2 will cope no worse, saving budget.
Both models have a glass platform and support up to 16 user profiles in the Mi Fit. However, the Body Composition Scale 2 is more accurate - an error of only ± 50 g versus ± 100 g in the younger model, and it is better suited for family use, as it recognizes users automatically (by weight and bioimpedance).
💡
If you only need weight and BMI, take the Mi Smart Scale 2. For a detailed analysis of body composition, choose Mi Body Composition Scale 2 - the difference in price is justified by the advanced functionality.
How to check the accuracy of Xiaomi weights before buying?
Even new scales can give inaccurate readings. To avoid disappointment, check the device immediately after purchase.
- Weigh yourself on a new scale and write down the result.
- Repeat the measurement on a mechanical or electronic scale (for example, in a clinic or fitness club).
- Compare the readings. The allowable difference is up to 200g for budget models and up to 100g for premium models.
If the difference exceeds the manufacturer's stated error, try calibrating the scales:
Turn on the scales and wait for zeros to appear | Put on the platform an object with a known weight (for example, a weight of 5 kg) | Hold the switch on 5 seconds to reset | Repeat the weigh-->
The accuracy also depends on the surface on which the scales are placed, with flat, hard floors (tile, laminate) being the best option, and carpeting or soft flooring can distort the results due to uneven load distribution.
⚠️ Attention: Bioimpedance analysis is sensitive to the time of day and hydration level. For accurate results, weigh yourself on an empty stomach in the morning, after using the toilet and before taking water.
Compatible with Mi Fit and other applications
Xiaomi’s scales are synchronized with its Mi Fit app, which stores measurement history, dynamics charts and recommendations. However, not all models support data export to third-party services. For example, Mi Smart Scale 2 only transfers data to Mi Fit, and Mi Body Composition Scale 2 is also compatible with Apple Health and Google Fit.
To connect the scales to the application:
- Download Mi Fit from the App Store or Google Play.
- Sign up or sign in to your Xiaomi account.
- Click "Add device" → "Libra" and follow the instructions.
- Stand on the scales – the data is automatically synchronized.
If the scales are not connected:
- 🔄 Reset the scales (take out and insert the batteries).
- 📱 Update the Mi Fit app to the latest version.
- 🔌 Make sure your phone is Bluetooth enabled.
- 📡 Check if the antivirus is blocking the connection with the weights.
💡
If Xiaomi scales do not save your measurement history, check the settings of the Mi Fit application. Guest access mode may be enabled, which does not save data.
Frequent Problems and How to Solve Them
Even Xiaomi’s high-quality scales can malfunction, and let’s look at the typical problems and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Libras not included | Batteries are dead or contacts are oxidized. | Replace batteries, wipe contacts with alcohol |
| Testimonies gallop | Uneven surface or dirt on sensors | Put the scales on a flat floor, wipe the platform |
| Not synchronized with Mi Fit | Outdated firmware or Bluetooth failure | Update the app, reboot the phone and scales |
| Err error. | Maximum load or sensor failure exceeded | Reset the scales (hold the 10 seconds button) |
If the scales show a Lo error, it means that the batteries are discharged. replace them with new ones (alkaline batteries are recommended). AAA). Mistake. --- or flashing zeros may indicate a sensor malfunction – in this case, contact the service center.

Where to buy Xiaomi scales: official and alternative options
Xiaomi's official scales are sold in Mi Store, Wildberries, Ozon, Yandex Market and AliExpress. However, be careful about shopping on marketplaces - there are often fakes.
- 📦 Packaging with hologram and barcode.
- 🔖 Serial number sticker on the bottom.
- 📄 Warranty card in Russian (for official deliveries).
- 🔋 Batteries are included (fake batteries are often not available).
Prices in official stores are usually higher, but you get a warranty (12-24 months) and support. On AliExpress, scales can be bought cheaper, but the risk of running into a fake is higher.
⚠️ Note: Fake Xiaomi scales often have an understated accuracy (the error is up to the point) ±500g) and are not synchronized with Mi Fit. check seller reviews and ratings before buying.
If you buy scales abroad (for example, on AliExpress), note that they can come with a fork type EU or US. It is rare to have an adapter in the kit, so prepare an adapter in advance.
