Xiaomi’s smart scales have long since ceased to be just a weight measurement device, they have become full-fledged assistants in health control. With modern models, you can track not only body weight, but also body fat percentage, muscle mass, water level and even bone density. However, the variety of lines (Mi Smart Scale, Mi Body Composition Scale, Xiaomi Smart Scale 3) often confuses customers: which scales are more accurate, which ones work longer from the battery, and which ones are suitable for professional athletes?
In this article, we will analyze all the current Xiaomi scale models (2026), compare their technical characteristics, identify strengths and weaknesses, and give recommendations for choosing according to your goals - whether it is a simple weighing or a deep analysis of body composition.
1. Overview of Xiaomi scales: what is the difference between the series
Xiaomi has launched smart scales under several brands: Mi, Xiaomi and Mijia. Despite the similarities, the models differ in sensor accuracy, the number of parameters measured and the price.
- 🔹 Mi Smart Scale 1/2 — basic models with weight measurement and IMD (Suitable for home use without in-depth analysis.
- 🔹 Mi Body Composition Scale 1/2 — Extended versions with bioimpedance analysis (fat, muscle, water, bone) or rather, but require proper use (wet feet, time of day).
- 🔹 Xiaomi Smart Scale 3 – flagship model with improved sensors, Wi-Fi support and advanced synchronization.
- 🔹 Mijia Bluetooth Body Fat Scale – budget version with a focus on compatibility with Mi Home.
It's important to understand that all Xiaomi scales work on the principle of bioimpedansometry: a weak electric current passes through the body, and the resistance calculates the composition parameters. This means that the accuracy depends on hydration, time of day and even eating. For example, if you weighed yourself immediately after a workout or heavy drinking, fat indicators can be underestimated.
2.TOP-5 models of Xiaomi weights in 2026: a comparative table
To make it easier to choose, we have compiled a table with key characteristics of the most popular models, and note the Accuracy and Synchronization columns, which are the criteria that are most often the cause of disappointment after purchase.
| Model | Measured parameters | Precision, d | Synchronization | Battery | Price, ₽ |
|---|---|---|---|---|---|
| Mi Smart Scale 2 | Weight, IMD | ±50 | Bluetooth (Mi Fit) | 4×AAA, 1 year | 1 200–1 500 |
| Mi Body Composition Scale 2 | Weight, fat, muscle, water, bones, IMD, visceral fat, metabolism | ±100 | Bluetooth (Mi Fit, Apple Health, Google Fit) | 4×AAA, 8 months | 2 500–3 000 |
| Xiaomi Smart Scale 3 | Weight, 13 parameters of body composition, heart rate | ±50 | Bluetooth + Wi-Fi (Mi Fit, third-party applications) | Li-ion, 180 days | 3 500–4 200 |
| Mijia Bluetooth Body Fat Scale | Weight, fat, muscle, water, IMD | ±100 | Bluetooth (Mi Home) | 4×AAA, 1 year | 1 800–2 200 |
| Xiaomi Mi Body Fat Scale (2026) | Weight, 9 parameters, body balance analysis | ±50 | Bluetooth 5.0 (Mi Fit, Apple Health) | Li-ion, 240 days | 2 800–3 300 |
You can see from the table that the most accurate model is the Xiaomi Smart Scale 3 (±50g error), but it is also the most expensive. If you want a scale with the maximum set of parameters, look for the Mi Body Composition Scale 2 or the new model from 2026. For those looking for a budget option, the Mijia Bluetooth Body Fat Scale will do, but note that it only syncs with the Mi Home.
⚠️ Attention: Bioimpedance scales are not recommended for pregnant women, people with pacemakers and those with metal implants, in which case it is better to choose a simple model without the function of measuring body composition (for example, Mi Smart Scale 2).
3. How to use Xiaomi smart scales: 5 key rules
Many users complain about Xiaomi’s unstable weights, not realizing that the problem lies in misuse.
- Measurement time: It is optimal to weigh yourself in the morning on an empty stomach, after going to the toilet, and evening readings can vary by 1-2 kg due to food and liquids eaten.
- Hydration: If you drink a lot of water before weighing, your fat will be understated (water conducts current better than fat).
- Leg position: You have to stand barefoot on metal electrodes (usually marked on the platform), socks or slippers will distort the results.
- Surface. Libras should stand on a flat, hard surface (tile, laminate), carpet or soft floor will lead to errors.
- Synchronization: Before using it for the first time, be sure to link the scales to the app (Mi Fit or Mi Home) via Bluetooth.
Install the Mi Fit application|Turn on Bluetooth on your smartphone|Put the scales on a flat surface|Weighing yourself with bare feet|Wait for data synchronization-->
If the scales show an error "Err" or not included, try:
- 🔋 Replace batteries (even if they are new – sometimes contact is bad).
- 📱 Reinstall the Mi Fit app and reconnect the device.
- 🔄 Reduce the scales to factory settings (usually hold the power button for 10 seconds).
What if the scales show the wrong weight?
4. Comparison with analogues: Xiaomi vs other brands
Xiaomi scales are often compared to models from Huawei, Honor and Withings. Let's take a look at the advantages and disadvantages of each brand:
| Criteria | Xiaomi | Huawei | Withings |
|---|---|---|---|
| precision | ±50-100 g | ±50 g | ±100 g (but better analysis algorithms) |
| Price. | 1 200–4 200 ₽ | 2 500–5 000 ₽ | 5 000–12 000 ₽ |
| Synchronization | Mi Fit, Apple Health, Google Fit | Huawei Health, limited to others | Withings App, Wide Integration |
| Design | Minimalist, glass | Metal + glass, premium | Premium design, water protection |
The main advantage of Xiaomi is the price / quality ratio. For example, Xiaomi Smart Scale 3 is not inferior to Huawei Smart Scale 3 in functionality, but it costs almost 2 times cheaper.
- 🩺 Measuring heart rate (Xiaomi only in Smart Scale 3).
- 🌡️ Weather control (pressure, temperature) to adjust the indicators.
- 📊 Advanced Analytics with Recommendations from Doctors.
If you need a scale strictly for weight control without bells and whistles, then Xiaomi is the best choice. For professional athletes or people with chronic diseases, it is better to consider Withings.
5. How to choose Xiaomi scales for your tasks: recommendations
The choice of model depends on your goals. Here are our recommendations:
- 🏠 For home use (weight) + IMD): Mi Smart Scale 2 is the simplest and most reliable model, suitable for the whole family.
- 💪 For fitness (body composition analysis): Mi Body Composition Scale 2 or the new 2026 model. They measure muscle mass, which is important for athletes.
- 📱 For integration with the ecosystem: If you have other Xiaomi devices (bracelet, smartphone), choose Xiaomi Smart Scale 3 – it supports Wi-Fi and better syncs.
- 💰 Budget option: Mijia Bluetooth Body Fat Scale – cheaper by 30-40%, but with reduced functionality.
- 👨👩👧👦 Family: User Recognition (up to 16 profiles) – Xiaomi Smart Scale 3 or Mi Body Composition Scale 2.
If you’re in doubt between the two models, look out for durability reviews: For example, the Mi Smart Scale 2 often breaks battery contacts, and the Xiaomi Smart Scale 3 has a built-in battery that lasts longer.
💡
Before buying, check if the model supports your height and weight.Most Xiaomi scales are designed for a maximum of 150-180 kg, and the minimum threshold is 5 kg. If your weight goes beyond this, look for specialized models (for example, Xiaomi Smart Scale 3 Pro up to 200 kg).
Frequent problems and their solutions
Even the most reliable scales can fail, and here are the most common problems and ways to fix them:
⚠️ Attention: If Xiaomi scales suddenly stop turning on, don't rush to throw them away! 80% of the time, the problem is solved by replacing batteries or resetting settings. Use high-quality alkaline batteries (for example, Duracell or Energizer) - cheap elements often cause failures.
| Problem. | Possible cause | Decision |
|---|---|---|
| Libras not included | Batteries are dead, bad contact. | Replace batteries, check for polarity |
| Err error. | Overload, uneven distribution of weight | Stand in the center of the platform, check the maximum weight. |
| Not synchronized with the phone. | Bluetooth is disabled, outdated firmware | Turn on Bluetooth, update the Mi Fit app |
| Shows the wrong weight | Uneven surface, dirt on sensors | Wipe the contacts with alcohol, put on a hard surface |
| Doesn't measure body composition. | Wet or dirty feet, socks | Weigh your bare feet, wipe your feet. |
If none of these methods helped, try updating the firmware of the scales through the Mi Fit app:
- Open Mi Fit and go to Profile → Devices → Your scales.
- Click on the three dots in the upper right corner and select Update firmware.
- Wait until the process is complete (don’t turn off Bluetooth!).
7.Alternative weights applications Xiaomi
The official Mi Fit app doesn’t always suit users because of limited analytics or advertising. Fortunately, Xiaomi scales support third-party programs:
- 📊 Google Fit – syncs data with other services (for example, Strava or MyFitnessPal).
- 🍎 Apple Health - for iPhone owners. Requires manual adjustment in Mi Fit.
- 🏋️ Yazio – fitness application with detailed analysis of body composition and nutritional recommendations.
- 📈 Health Sync – a plugin for automatic synchronization between different platforms.
To connect scales to Google Fit:
- Open Mi Fit and go to Profile → Settings → Accounts and Sync.
- Select Google Fit and log in.
- Allow access to health data.
If you're using Apple Health, note that not all parameters are transmitted correctly. For example, visceral fat readings may not show up. In this case, try the Health Sync app for manual adjustment.
💡
For maximum accuracy, use the same application all the time, and frequent program changes can lead to discrepancies in the data due to different processing algorithms.
