Smart scales Xiaomi or Huawei: which is better to buy in 2026? Comparison of 7 key parameters

Choosing between Xiaomi and Huawei’s smart scales isn’t just a brand issue, but finding a balance between measurement accuracy, app usability, and extra features. Both companies offer devices with body composition analysis, smartphone synchronization, and stylish design, but the approaches to implementing these capabilities are very different. For example, Xiaomi Mi Body Composition Scale 2 scales are known for their democratic price and integration with the Mi Home ecosystem, while Huawei Body Fat Scale 3 stands out with advanced sensors and support for Huawei Health’s own platform.

But how do you know which is more important: accuracy of muscle mass measurement or convenience of synchronization with fitness trackers of the same brand? Or maybe you are critical to compatibility with iOS or the ability to weigh babies? In this article, we will analyze 7 key parameters — from technical characteristics to the nuances of operation — and help determine which smart scales are better to buy for your tasks. Compare flagship models, budget options and even rare features that manufacturers prefer not to mention.

1. Measurement accuracy: who cheats the least?

The main question when buying a smart scale is how much you can trust it. Both companies use the bioimpedance analysis (BIA), but implement it differently. Xiaomi scales (for example, Mi Body Composition Scale 2) are equipped with 4 electrodes — two on each leg. This allows you to evaluate body composition with an error of up to ± 3% for fat mass and ± 0.5 kg for weight. However, the accuracy drops when you have wet feet or after intense training due to changes in skin resistance.

Huawei’s Body Fat Scale 3 and Scale 3 Pro models use 8 electrodes (4 on each platform), which should theoretically improve accuracy. The manufacturer claims an error of ±1.5% for fat and ±0.3 kg for weight. But independent tests (for example, from TechMoan) show that the difference with medical weights is up to 5% in some cases – especially in people with non-standard physique (for example, bodybuilders or lean women).

• 🔬 Xiaomi: 4 electrodes, error ±3% (fat), ±0.5 kg (weight) Better for "average" users.
• 🔬 Huawei: 8 electrodes, error ±1.5% (fat), ±0.3 kg (weight) Theoretically more accurate, but depends on the build.
• ⚠️ Common disadvantage: Both brands fail when wet feet or after a sauna – skin resistance distorts the data.

⚠️ Note: If you use scales for medical monitoring (such as diabetes or heart disease), neither Xiaomi nor Huawei will replace professional equipment.

2. Functionality: What do scales know besides weight?

Modern smart scales are mini-laboratories that can measure up to 13 body parameters. But do you need them all? Let's look at what Xiaomi and Huawei offer besides the base weight.

As you can see from the table, the Huawei Scale 3 Pro leads in terms of the number of parameters, but here's the question: do you need them? For example, visceral fat (fat around the internal organs) is a useful indicator for assessing the risk of diabetes, but its accuracy on household scales is questionable even by the manufacturer. The protein analysis in Scale 3 Pro is generally more marketing move — the error reaches ± 15%, which makes it useless for athletes.

On the other hand, Xiaomi doesn’t overload users with data by focusing on basic metrics, which is a plus for those who don’t want to understand dozens of charts, but if you care about muscle balance (for example, for training adjustments), Huawei will give you more useful information.

Ecosystem compatibility: which is more important – Mi Home or Huawei Health?

If you already have Xiaomi or Huawei gadgets, the choice of scales can be simplified — but not always. Xiaomi scales work through the Mi Fit app (or Zepp Life for new models), which syncs with the Mi Band, Mi Watch and other devices of the brand. This is convenient for those who keep a workout diary and want to see all the metrics in one place.

• 📱 Mi Fit is updated frequently and may “lose” your data history when you change the version.
• 🔄 Synchronization with Google Fit works crooked – sometimes duplicate records.
• 🍎 iOS functionality is reduced: no detailed schedules for weeks.

Huawei has its own app, Huawei Health, which is better optimized for Android (especially on Huawei/Honor smartphones).

• 📊 More detailed reports with comparisons by week/month.
• 🩺 Integration with Huawei Watch to correct weight training.
• 🌍 Google Fit and Apple Health support (but with up to 24 hours of sync delay).

The key point is that if you have an iPhone, both brands will be limited, but Huawei at least keeps the full data history in the cloud, whereas Xiaomi can reset it when you reinstall the app.

⚠️ Note: If you plan to use scales for the whole family, consider that Huawei Health allows you to create up to 10 profiles, while Mi Fit only allows you to create 8. Huawei has a feature to recognize the user by weight (if the difference between family members is more than 5 kg), and Xiaomi will have to choose a profile manually.

4. Design and usability: glass vs. plastic

Both brands look minimalistic on the outside, but the materials and ergonomics are different: Xiaomi has traditionally used tempered glass (such as in Mi Body Composition Scale 2) with anti-slip coating. The scales are slightly concave, which is convenient for people with a wide foot.

Huawei uses matte plastic with metal inserts in Body Fat Scale 3 models, which is more practical in everyday life (no dust and scratches are visible), but less premium in appearance, but Huawei’s scales are thinner (1.8 cm vs. 2.2 cm in Xiaomi) and lighter (1.2 kg vs. 1.5 kg), which is important for frequent travel.

Another nuance is the size of the platform:

• 📏 Xiaomi Mi Body Composition Scale 2: 300×300 mm - suitable for the feet up to 44 size.
• 📏 Huawei Body Fat Scale 3: 260×260 mm - tighter than the size 42.

If you have people with a big foot in your family, Xiaomi will be more comfortable, but for a compact bathroom, Huawei is better, you can hide it in a locker.

💡

To make the scales last longer, avoid putting them on carpets or soft surfaces. Bioimpedance analysis requires close contact with the floor, otherwise the data will be distorted. The optimal is tile or laminate.

5. Autonomy and power: how long will the battery last?

Both brands use 4 AAA batteries, but their lifespan is very different. Xiaomi’s battery range lasts 6-8 months for daily use (according to GSMArena tests), Huawei has a better score – up to 12 months, thanks to a more energy-efficient chip.

But there’s a hidden downside: in the Huawei Body Fat Scale 3, the battery compartment closes on a latch that’s easy to break when replaced. Xiaomi has a magnet lid that’s more reliable, but can accidentally open when transported.

If you are a forgetful user, pay attention to the charge indication:

• 🔋 Xiaomi warns of low charge 2 weeks before full discharge.
• 🔋 Huawei: Signals Only 3 Days in advance – Risk of being without weights at the most inopportune moment.

6.Price and availability: where is the best place to buy?

As of 2026, the prices of the two brands’ smart scales vary by model and region. In Russia and CIS, Xiaomi is traditionally cheaper due to logistics and frequent discounts.

• 💰 Xiaomi Mi Body Composition Scale 2: 2 500–3 500 ₽ (It's often in sales for 2,000. ₽).
• 💰 Huawei Body Fat Scale 3: 3 500–4 500 ₽ (Discounts are rare, usually not below 3200 ₽).
• 💰 Huawei Scale 3 Pro: 5 000–6 500 ₽ (The most expensive model with advanced analytics).

Where to look for profitable offers?

Search on AliExpress (but check reviews about the seller)|Keep an eye on sales on Wildberries/Ozon|Checking official shops Xiaomi/Huawei (Sometimes they give discounts when buying with other gadgets)|Search for used models on Avito (but only with a check and warranty)|Compare prices in electronics stores (M.Video, Eldorado) using services such as "Yandex Market"-->

Important: If you buy scales abroad (for example, on AliExpress), pay attention to the firmware version. Chinese versions of Xiaomi may not support Russian in the application, and Huawei sometimes blocks access to servers for devices purchased outside official stores.

⚠️ Note: When buying used scales, check if the weighing counter in the application is reset. Some models (for example, Xiaomi Mi Scale 2) limit the number of records in the device's memory - after 10,000 weighings, the scales begin to "forget" old data.

7 Rare Functions: What Scales Can Do, What They Don't Talk About?

In addition to the standard features, both brands have hidden chips that manufacturers do not advertise.

• 👶 Baby Mode: Huawei Body Fat Scale 3 can weigh children from 0 to 3 years old (with a special feature in the app), whereas Xiaomi officially supports only a weight of 10 kg.
• 🐕 Animal weighing: Both models can show the weight of pets, but Huawei automatically ignores such records in history (so as not to spoil the statistics), and Xiaomi keeps them as normal.
• 📱 Offline mode: Xiaomi can save up to 16 weigh-ins without connecting to a phone, Huawei can only save 8.
• 🔄 Data Export: Huawei Health allows story to be uploaded to the Internet CSV For Excel analysis, Mi Fit does not have such a function.

Another little-known fact is that the Huawei Scale 3 Pro scales can measure sleep quality when synchronized with the Huawei Band 7 fitness bracelet. The algorithm analyzes changes in weight at night (due to sweating) and correlates them with sleep data. The accuracy is questionable, but for introspection enthusiasts it is an interesting option.

💡

If you want scales for the whole family, including children and pets, the Huawei Body Fat Scale 3 will be more versatile. If autonomy and simplicity are important, choose Xiaomi Mi Body Composition Scale 2.
