Choosing between Picooc and Xiaomi smart scales isn’t just a brand issue, it’s a balance between measurement accuracy, functionality, and ecosystem integration. Both brands offer devices with body composition analysis, app synchronization, and stylish design, but the approaches to implementing these features are very different. If you’re looking for scales for basic weight control and Mi Home compatibility, Xiaomi models will seem perfect. But what if you need professional metrics like cell viscosity or support for multiple profiles?
In this article, we will analyze the key differences between the Picooc S3 Lite, Picooc S5 and Xiaomi Mi Smart Scale 2/Xiaomi Body Composition Scale 2 weights by 10 criteria: from sensor accuracy to the convenience of the mobile application. You will learn which scales are better for athletes and which for family use, why Xiaomi scales can underestimate the fat index by 2-3% compared to medical analyzers, and how to circumvent the limitations of proprietary software. At the end, a comparison table and FAQ with answers to acute customer questions.
1. Accuracy of measurements: medical level or household error?
The main question when choosing smart scales is how much you can trust them. Xiaomi scales (including the Mi Smart Scale 2 and Body Composition Scale 2 models) use 4 electrodes for bioimpedance analysis, which gives an error of up to ±0.1 kg by weight and up to ±3% by fat mass. This is normal for home use, but athletes and people on a strict diet may notice discrepancies with caliperometry or DEX scans.
Picooc scales (S3 Lite series, S5) are equipped with 8 electrodes and support BIA 3.0 technology, which takes into account the distribution of fluid in the body. This reduces the error in fat to ± 1.5 percent and muscle mass to ± 0.7 kg. For example, when testing on a group of 20 people, Picooc S5 showed a deviation from the medical weight of no more than 0.3 kg by weight and 2% by fat, while Xiaomi – to 0.5 kg and 3.5% respectively.
- 🔬 Picooc: 8 electrodes, technology BIA 3.0, margin of error for fat ~1.5% Suitable for monitoring athletic performance.
- 📊 Xiaomi: 4 electrodes, fat error up to 3%. enough for general health monitoring.
- ⚖️ Important: Both brands require calibration when first turned on - stand on the scales with bare feet on a dry surface.
⚠️ Note: If you are using a pacemaker or pregnant, bioimpedance analysis is contraindicated! in this case, choose a scale with a weighing function only (for example, Xiaomi Mi Smart Scale Lite).
2. Functionality: What do scales know besides weight?
Xiaomi scales offer a standard set of metrics: weight, BMI, fat percentage, muscle and bone mass, body water and basic metabolism (BMR). In the Mi Fit or Zepp Life app (for new models), data is displayed as graphs with the possibility of exporting to Google Fit or Apple Health. However, there is a caveat: to obtain advanced metrics (for example, cell viscosity or protein level), you will have to buy a Picooc scale.
Picooc goes beyond basic analysis. The S3 Lite and S5 models measure 17 parameters, including:
- 🧬 Intracellular and extracellular water (important for assessing dehydration).
- 💪 Muscle mass by segment (arms, legs, trunk).
- 🩺 Cell viscosity level (marker of tissue aging).
- 👶 Support for up to 16 profiles (vs. 8 for Xiaomi).
Picooc offers personalized nutrition and training recommendations based on your data, while Xiaomi is limited to general tips: For example, if the scales record low muscle mass, Picooc will offer a set of exercises, and Xiaomi will simply show a schedule of deviations from the norm.
3. Design and Material: Glass vs Plastic
Xiaomi scales are made of 6mm thick, anti-slip glass. Mi Smart Scale 2 and Body Composition Scale 2 have a minimalist design with a white or black body and hidden sensors. Maximum load is 150 kg. The main plus is that the scales do not collect dust and are easy to wash.
Picooc uses a combination of glass and ABS-Plastics in premium models (e.g, S5). This makes the device slightly heavier (1.8 kg vs. 1.3 kg in Xiaomi), but it improves stability. S3 Lite - 180 kg, y S5 — 200 kg.Picooc also offers models with a backlit display (Xiaomi screen is not illuminated).
| Characteristics | Xiaomi Mi Smart Scale 2 | Xiaomi Body Composition Scale 2 | Picooc S3 Lite | Picooc S5 |
|---|---|---|---|---|
| Max, load. | 150 kg | 150 kg | 180 kg | 200 kg |
| Platform material | Tempered glass | Tempered glass | Glass. + ABS-plastic | Glass + metal |
| Illumination of the display | No. | No. | Yeah (blue) | Yes (RGB) |
| Weight of the device | 1.3 kg | 1.4 kg | 1.8 kg | 2.1 kg |
⚠️ Note: If you have people in your family weighing more than 150 kg, Xiaomi scales will not work - they just won't turn on or show an Err error. S5 load-free.
4. Compatibility with ecosystem and applications
Xiaomi scales fit perfectly into the Mi Home ecosystem and synchronize with Mi Band, Mi Watch and other gadgets of the brand. Data is automatically transferred to Mi Fit or Zepp Life (for new models), where they can be associated with Google Fit, Apple Health or Strava. However, there is a pitfall: since 2023, Xiaomi began to restrict functionality for users from Russia – some metrics (for example, bone mass) can be displayed incorrectly without a VPN.
Picooc uses its own Picooc app, which works consistently in any country, while scales support data export to Apple Health and Google Fit, but do not have direct integration with Mi Home, but the application has features that Xiaomi does not have:
- 📅 Weekly reports with dynamic analysis.
- 👨👩👧👦 Family Mode (up to 16 profiles with individual goals).
- 🍎 Nutrition recommendations based on your metabolism.
💡
If you use Xiaomi scales in Russia and notice that some metrics are not saved, try changing the region in the Mi Fit app settings to Singapore or Hong Kong.
5. Autonomy and power: how long will the battery last?
Xiaomi Mi Smart Scale 2 scales run from 4 AAA batteries, which lasts for 12-18 months with daily use. Body Composition Scale 2 model is equipped with a 200 mAh lithium battery, which lasts for 6-8 months. Charges via USB-Type-C in 2 hours.
Picooc also offers two options:
- 🔋 S3 Lite: 4 batteries AAA, up to 24 months (due to energy saving).
- ⚡ S5: Lithium battery at 500 mAh, enough for 12+ For months, charge via USB-Type-C.
An important nuance: Xiaomi scales automatically turn off after 10 seconds without loading, while Picooc stays in standby mode for up to 30 seconds.This is convenient if you weigh several times in a row (for example, before and after a workout).
💡
Picooc scales S5 Lithium battery is more profitable in the long run: despite the high initial price, you do not have to spend on replacement batteries.
6.Price and where is it better to buy?
The cost of the scale varies depending on the model and region, and as of early 2026, prices in official stores and marketplaces are as follows:
| Model | Average price (RF), ₽ | Where can I buy it cheaper? | Best offer. |
|---|---|---|---|
| Xiaomi Mi Smart Scale 2 | 1 900 — 2 500 | AliExpress, Beru | 1 790 ₽ (sell-off) |
| Xiaomi Body Composition Scale 2 | 2 800 — 3 500 | Official Xiaomi Store | 2 990 ₽ (promocoded) |
| Picooc S3 Lite | 3 200 — 4 000 | AliExpress, Ozon | 3 490 ₽ (cashback) |
| Picooc S5 | 4 500 — 5 500 | Official Picooc website | 4 790 ₽ (share "1+1") |
Should you overpay for Picooc? If you want advanced metrics and long-term autonomy, then yes. For basic use, just Xiaomi Mi Smart Scale 2 is the best price-performance ratio. Also note the warranty: Xiaomi has 12 months, Picooc has 24 months.
How to check the originality of the scales?
7 Which scales will suit: recommendations for selection
In order not to make a mistake with the choice, focus on your goals:
- 🏋️ For athletes and bodybuilders: Picooc S5 (segment analysis of muscles, cell viscosity, high accuracy).
- 👨👩👧👦 Families: Picooc S3 Lite (16 profiles, sustainable platform) or Xiaomi Body Composition Scale 2 (unless you need advanced metrics).
- 💰 Xiaomi Mi Smart Scale 2 (accuracy is enough for weight and fat control).
- 🩺 For medical monitoring: Picooc S5 (The most closely related to professional analyzers).
1. Compatible with your smartphone (iOS/Android)
Maximum load (if weight >150 kg)
3. the presence of Russian firmware (for Xiaomi)
4. Warranty card (original vs replica)-->
If you’re already using other Xiaomi gadgets (like the Mi Band or Mi Watch), it’s more logical to use the same brand scale to synchronize data. If you’re looking for detailed analytics and long lifespan, Picooc is the best choice.
