Xiaomi Mijia Smart Scale 3 Review: Best Budget Body Composition Scale

The Xiaomi Mijia Smart Scale 3 is the latest generation of Xiaomi’s best-selling body composition scale, featuring Bluetooth 5.0 connectivity, 13 health metrics, and seamless integration with the Mi Home/Zepp Life ecosystem — all for just ¥99 (~$14). With a 4.6/5 JD rating from over 50,000 reviews, it earns our ✅ Worth Buying recommendation as the best all-around smart scale under ¥200.

Introduction

Xiaomi has dominated the smart scale category in China since the original Mijia Scale launched years ago. The formula is simple: a well-designed tempered glass scale with BIA body composition sensors, app connectivity, and a price that undercuts the competition. The Smart Scale 3 is the latest iteration, refining the design and updating the Bluetooth standard.

For ¥99, the Scale 3 competes directly with budget options from Surmount and Yunmai. But Xiaomi brings something those brands can’t match: the Mi Home ecosystem, which integrates seamlessly with Xiaomi wearables, band scales, and other health devices. After two weeks of testing against a professional scale, we can confirm the Smart Scale 3 is the best budget smart scale for most users.

Design & Build Quality

The Smart Scale 3 adopts a completely flat design — no raised edges, no visible sensors. The surface is a single sheet of 6mm tempered glass, with ITO conductive coating for BIA measurement instead of traditional metal electrode pads. This gives it a seamless, premium look that resembles scales costing five times as much. The LED display is embedded under the glass and lights up only when weight is detected, creating a clean “disappearing display” effect.

The scale is available in white or black, both with a minimalist aesthetic that fits any bathroom. The plastic undercarriage houses the electronics and four anti-slip rubber feet. Build quality is excellent for the price — the glass is thick and resistant to cracking, and the scale feels solid underfoot. The battery compartment on the bottom uses 4 AAA batteries.

“颜值太高了，全平玻璃面板没有凸起的电极片。放浴室里看着很高级。比之前买的那些塑料秤好看太多了。” — JD Review by 周*, Verified Purchase 💡 The seamless glass design is a major aesthetic upgrade over electrode-pad scales.

Performance & User Experience

Weight measurements are consistent within 0.05kg across repeated readings. Body composition metrics show reasonable accuracy for the price point — within 2-3% of professional equipment, which is excellent for a single-frequency BIA scale. The 13 metrics cover weight, BMI, body fat, muscle mass, bone mass, body water, protein, visceral fat, and more.

The Mi Home integration is the real differentiator. The scale automatically syncs readings to the app when you step on with a paired phone nearby. The Zepp Life app (formerly Mi Fit) provides a clean dashboard, trend charts, and goal tracking. For users with Mi Bands or Xiaomi watches, all health data consolidates in one view. Auto-recognition for up to 8 users works well — it correctly identified each family member based on weight range.

“之前用朋友的Yunmai，感觉小米的App好用太多了。数据界面清晰，还结合了手环的数据做综合分析。” — JD Review by 陈*, Verified Purchase 💡 The Mi Home app ecosystem gives Xiaomi a distinct advantage over competing brands.

What Chinese Users Say

With over 50,000 ratings at 4.6/5, the Smart Scale 3 is one of the most popular health devices on JD.com:

“99块钱还要什么自行车？日常记录体重完全够用了。体脂数据虽然不太准，但每天称看趋势是有意义的。” — “What more do you want for ¥99? Perfectly adequate for daily weight tracking. Body fat data isn’t super accurate but trending is meaningful.” 💡 Users overwhelmingly agree that value-for-money is exceptional.

“第三代的隐藏显示太赞了，之前二代那个外露的LED看着有点廉价。这个全平玻璃手感很棒。” — “The hidden display on Gen 3 is great — Gen 2’s exposed LED looked a bit cheap. This full-flat glass feels premium.” 💡 The design evolution from Gen 2 to Gen 3 is praised.

“买给爸妈的，教了一次就会用了。每天称一下数据自动同步到我的手机上，可以远程关注他们的身体状况。” — “Bought for my parents. They got it after one lesson. They weigh daily and data auto-syncs to my phone so I can monitor their health remotely.” 💡 Remote monitoring of elderly parents is a surprisingly valuable use case.

“唯一缺点是不带USB充电，还要买电池。其他方面都很满意。推荐买充电电池配合使用。” — “Only downside is no USB charging — still need batteries. Satisfied with everything else. Recommend using rechargeable batteries.” 💡 The lack of rechargeable battery is the most common criticism.

Pros and Cons

Pros

• Seamless tempered glass design with hidden display looks premium
• Excellent Mi Home ecosystem integration with wearables and health data
• Consistent weight and body composition measurements for trend tracking
• Auto-recognition up to 8 users works reliably for families

FAQ

Q: How is the Smart Scale 3 different from the Xiaomi Scale 2? A: Key upgrades: hidden LED display (vs exposed on Scale 2), Bluetooth 5.0 (vs 4.2), ITO-coated glass (vs metal electrodes), and slightly improved BIA accuracy. The core feature set is similar — the main difference is design and connectivity.

Q: Can I use it without a smartphone? A: Yes. The scale functions as a basic weight scale without a phone. It will display weight and estimate body fat on its own. However, most smart features and historical data tracking require the app.

Q: Does it work with Apple Health? A: Yes, Zepp Life can sync data to Apple Health. You need to enable the integration in the app settings. It supports steps, weight, body fat, and BMI data transfer.

Q: How accurate are the body composition readings for athletes? A: Single-frequency BIA scales have known limitations for athletes, muscular individuals, and people with very high or very low body fat percentages. The Scale 3 is calibrated for the average person. Athletes should consider multi-frequency BIA scales for better accuracy.

Q: Does the scale measure visceral fat accurately? A: Visceral fat estimation is derived from BIA data plus body morphology calculations. It provides a useful trend indicator — a rising visceral fat number is worth paying attention to — but shouldn’t be taken as a clinical measurement.

Verdict and Rating

The Xiaomi Mijia Smart Scale 3 is the best ¥100-scale you can buy. The combination of sleek design, reliable measurements, and the powerful Mi Home ecosystem makes it the default recommendation for anyone starting with smart health tracking. The BIA accuracy is good enough for trend tracking, and the auto-recognition makes it a natural fit for families.
