Xiaomi scales: what is the difference between models and which to choose in 2026

Xiaomi scales have long ceased to be a simple accessory for measuring weight — they have become full-fledged gadgets for monitoring health. But the variety of models (Xiaomi Smart Scale 2, Mi Body Composition Scale 2, Xiaomi Smart Scale 3 and others) often confuses buyers: how do they differ, except for the price? In this article, we will analyze in detail the key differences between the popular Xiaomi scales, their technical characteristics, functionality and compatibility with the Mi Fit application.

You'll learn which models support body composition analysis (fat, muscle, water) and which are limited to baseline measurements. We'll compare measurement accuracy, maximum load, design, and even synchronization nuances with other Xiaomi ecosystem devices (such as Mi Band bracelets). If you're fluctuating between a budget and a premium model, here's the pros and cons.

Spoiler: not always the most expensive model meets expectations. For example, Xiaomi Smart Scale 3 is inferior to Mi Body Composition Scale 2 in muscle mass analysis, but wins in synchronization speed. Xiaomi Smart Scale Lite is completely devoid of Bluetooth — and this is not a mistake, but a conscious decision of the manufacturer. Read on, so as not to overpay for unnecessary functions!

1.The main lines of Xiaomi weights: a brief overview

All scales Xiaomi can be divided into three categories:

• 📏 The base models (Xiaomi Smart Scale Lite, Xiaomi Smart Scale 1) – measure only weight, without analyzing body composition, suitable for those who need a simple and cheap scale.
• 🧬 Advanced models (Xiaomi Smart Scale 2, Mi Body Composition Scale 2) – analyze fat mass, muscle, water, bone tissue, ideal for athletes and those who follow health.
• 💎 Premium models (Xiaomi Smart Scale 3, Xiaomi Body Fat Scale) 2S) — Add extended metrics (such as visceral fat or metabolic age), improved design and faster synchronization.

It is important to understand that even within the same lineup, there may be regional versions, such as the Mi Body Composition Scale 2 for China and the global version differ in firmware and supported languages in the application, and some models (such as the Xiaomi Smart Scale 3) have different color options, but are technically identical.

If you see an S (like 2S) in the title, it usually indicates an updated firmware or minor upgrades (like Apple Health support), but not always: sometimes it’s just a marketing ploy.

Technical specifications: comparative table

To keep the numbers from getting confused, we put the key parameters of popular models into one table: pay attention to the maximum load — if you weigh more than 150 kg, many Xiaomi scales simply can not cope. Also important is the measurement error: on budget models it can reach ± 100 g, for premium models it can reach ± 50 g.

The critical difference is that Xiaomi Smart Scale Lite scales do not have Bluetooth and do not sync with Mi Fit. Data will have to be entered manually - this is the only model in the lineup with such a restriction.

Also, pay attention to the type of battery:

Models with 4×AAA are cheaper to maintain, but batteries discharge faster (when used actively – every 6-12 months).

Lithium-ion battery scales (Mi Body Composition Scale 2, Smart Scale 3) can last up to 1-2 years, but they cannot be replaced on their own.

💡

If you choose between Xiaomi Smart Scale 2 and Mi Body Composition Scale 2, pay attention to the weight of the user: the first model measures weight up to 100 kg more accurately, the second one is optimized for weight 100-150 kg.

3. Body composition analysis: what different models can do

The main difference between Xiaomi's advanced scales and the budget scales is the ability to analyze body composition using the bioimpedance analysis (BIA) method. Four electrodes on the surface of the scales pass a weak electric current through the body and measure the resistance of different tissues. But not all models are equally accurate!

Here are the parameters that can be measured by weights:

• 📊 Weight is the basic function in all models.
• 💧 Percentage of water - shows hydration level. Available in Smart Scale 2 and older.
• 🍗 Fat mass is the percentage of body fat, important for assessing fitness.
• 💪 Muscle mass shows muscle development. In Mi Body Composition Scale 2 is analyzed separately for the arms, legs and trunk.
• 🦴 Bone mass – helps track the health of the skeleton.
• 🔥 Basic metabolism (BMR) — How many calories does the body spend at rest.
• 👴 Metabolic age only in Smart Scale 3 and Body Fat Scale 2S.

An important nuance: the accuracy of the analysis of body composition depends on the moisture of the skin, the time of day and even the phase of the menstrual cycle (in women), the manufacturer recommends weighing yourself in the morning on an empty stomach, after going to the toilet and without clothes.

⚠️ Note: Bioimpedance analysis does not work for people with pacemakers or other implanted electronic devices, and may be distorted during pregnancy or severe swelling.

If you want the most accurate data, look for the Mi Body Composition Scale 2 – it uses 4 high-precision sensors (instead of 2 for Smart Scale 2), which reduces the error to ± 3% for fat mass.

4. Compatible with Mi Fit and other applications

All Xiaomi scales (except Smart Scale Lite) are synchronized with the official Mi Fit app (now renamed Zepp Life in some regions).

• 📱 Android/iOS: All models support both platforms, but iPhone may require manual connection via Settings → Bluetooth.
• 🌍 Regional restrictions: some features (e.g. visceral fat) are only available in the Chinese version of Mi Fit.
• 🔄 Data Export: Smart Scale 3 and newer supports synchronization with Google Fit, Apple Health and Samsung Health.
• 👨‍👩‍👧‍👦 Multiplayer mode: up to 16 profiles on a single scale (in Smart Scale 2 and older).

If you use other Xiaomi gadgets (such as the Mi Band 7 or Xiaomi Watch S3), the weight data will automatically be combined into the Mi Fit for comprehensive health analysis, for example, the app may advise you to increase your water consumption if the scales show low hydration levels and the bracelet detects little activity.

⚠️ Attention: When you first connect the scales to Mi Fit, be sure to specify the exact growth - it depends on the correctness of the calculation of BMI and other parameters. If Later you change the growth in the profile, you have to reset the statistics and start over.

For those who don’t want to use Mi Fit, there are alternatives:

Yazio supports the import of data from Xiaomi scales through Google Fit.

FatSecret - allows you to manually enter body composition indicators.

Apple Health – aggregates data if the scales are synchronized via Mi Fit.

Install the Mi Fit| app | Turn on Bluetooth on your smartphone | Add the device via Profile → Add the device | Specify height, weight and age in profile | Perform the first weigh-in to calibrate-->

5. Design and Material: What Affects Durability

Xiaomi scales look the same on the outside: glass surface, minimalist body.

• 🔲 Platform material: - Smart Scale Lite - plastic with anti-slip legs. - Smart Scale 2/3 Mi Body Composition Scale 2 — hardened glass 6 mm (more durable but slippery on wet feet).
• 🎨 Color options: - Budget models - white or black only. - Smart Scale 3 is available in gold and pink.
• ⚖️ Weight and dimensions: - All scales weigh ~1.5 kg, but Smart Scale 3 is 10% thinner (3.2 cm vs. 3.5 cm in Smart Scale 2).

The problem of slipping is relevant for all glass models. If you weigh in the bathroom, where the floor is often wet, it is better to choose a Smart Scale Lite with rubber legs or buy an anti-slip mat.

Also pay attention to the placement of sensors:

In Smart Scale 2, the electrodes are located in the corners - you need to stand strictly in the center.

In Mi Body Composition Scale 2, sensors are distributed across the entire surface, making it easier to weigh.

If you plan to take scales on a trip, consider that the Smart Scale Lite is the lightest (1.2 kg), but requires batteries. The Mi Body Composition Scale 2 models weigh more, but do not need to replace batteries.

💡

For families with children or the elderly, it is better to choose a model with a plastic platform (Smart Scale Lite) - it is less traumatic when falling.

6. Which model to choose in 2026: budget recommendations

Xiaomi’s weights are based on your goals and budget, and here are our recommendations:

If you're an athlete or you're a dieter, take the Mi Body Composition Scale 2, which gives you the most complete picture, and for the elderly or those who just want to control weight, Smart Scale Lite is enough.

Savings tip: often on AliExpress or in the official Xiaomi store there are sales, where Smart Scale 2 can be bought for a price. ~1 800 ₽ (30% off, watch the stock!

Don’t buy Xiaomi scales older than 2020 (like the Mi Smart Scale 1) – they don’t support the latest Mi Fit versions and may have synchronization issues.

7. Frequent problems and how to solve them

Even Xiaomi scales have crashes, and here are the most common problems and solutions.

• 🔋 Libras not included: - Check the batteries (in models with the AAA). - For Lithium-ion battery scales, plug in the charge for 30 minutes. - If it doesn't help - reset the settings by holding the 10 seconds switch button.
• 📶 Not synced with Mi Fit: - Remove the device from the application and connect again. - Update Mi Fit to the latest version. - On iPhone, enable Bluetooth access for Mi Fit in privacy settings.
• ⚖️ Put the scales on a flat, hard surface (not on the carpet!) Calibrate by pressing the corner of the platform (in some models). ±200g – contact the service (probably damaged sensors).
• 🔄 No data is saved: - Check that the correct user profile is selected in Mi Fit. - Update the firmware of the scales through the application.

⚠️ Note: If Xiaomi scales show weight 2-3 kg more than mechanical scales, do not panic. Electronic scales often take into account the weight of clothes (even light) and round the values.

If the scales don't work after all the manipulations, check to see if the warranty period (usually 12 months) has expired. Xiaomi service centers often change faulty sensors for free.
