Choosing between Picooc and Xiaomi smart scales isn’t just a brand issue, but finding a balance between accuracy, functionality and price. Both manufacturers offer devices with body composition analysis, app synchronization and stylish design, but the approaches to implementing these features are very different. Picooc positions itself as a professional tool for athletes and health care people, while Xiaomi is betting on accessibility and integration into its Mi Home ecosystem.
In this article, we will discuss the key differences between the Picooc S3, Picooc S5 and Xiaomi Mi Body Composition Scale 2, Xiaomi Smart Scale 2. You will learn which scales more accurately measure weight and fat percentage, which is better for the application, and which will be suitable for families with children.
1. Measurement accuracy: who lies the least?
The key to choosing a smart scale is accuracy in body composition analysis. It's important to understand that no household scale will replace medical equipment, but some models are closer to the truth than others. Picooc uses BIA technology with 4 electrodes, while Xiaomi in most models is limited to 2 electrodes. On paper, this gives the advantage of Picooc, but in practice it is more difficult.
According to independent tests (including data from Reddit and 4PDA), the Xiaomi Mi Body Composition Scale 2 shows more stable results when re-weighing, while the Picooc S3 can give a range in fat mass by up to 1.5-2% depending on the time of day.
- 🔬 Picooc S5: 4 electrodes, support for cell viscosity measurement (unique for household scales), but requires ideal conditions (wet feet, same weighing time).
- 📊 Xiaomi Mi Body Composition Scale 2: 2 electrodes, simple calibration, smaller data scatter with regular use.
- ⚖️ Picooc S3 Lite: budget version with 2 electrodes, accuracy comparable to Xiaomi Smart Scale 2, but loses in stability.
⚠️ Attention: If you use a pacemaker or other implanted medical device, you can't use a smart scale with bioimpedance analysis! This can cause malfunctions in the device.
Functionality and capabilities: what do scales know besides weight?
Modern smart scales are not just measurements of body weight; they look at fat percentage, muscle mass, water level, bone mass, even metabolic age. But do you need all these metrics? Let's look at what's really good for you and what's just marketing.
Picooc scores up on a scale of up to 13 (including cell viscosity and protein mass), while Xiaomi is limited to 9-10. However, most users regularly only follow 3-4 metrics: weight, fat percentage, muscle mass and water. The rest of the data is often left unclaimed. Xiaomi has a feature – a mode for pregnant women, which turns off bioimpedance analysis (safe for the fetus) and shows only weight.
| Function | Picooc S5 | Xiaomi Mi Body Composition Scale 2 | Picooc S3 Lite | Xiaomi Smart Scale 2 |
|---|---|---|---|---|
| Number of electrodes | 4 | 2 | 2 | 2 |
| Analysis of cell viscosity | ✅ | ❌ | ❌ | ❌ |
| Pregnancy regimen | ❌ | ✅ | ❌ | ❌ |
| Max: Number of users | 16 | 16 | 8 | 16 |
| Synchronization with Apple Health | ✅ | ❌ | ✅ | ❌ |
Applications and ecosystem: where is the best place to store data?
Even the most accurate scales are useless if the app is uncomfortable or doesn’t sync with other services, where Picooc and Xiaomi go their separate ways: one is focusing on detail, the other is focusing on integration.
The Picooc app (available on iOS and Android) offers detailed charts, comparisons to WHO regulations, and even nutrition recommendations. However, the interface is overloaded and Russian localization is lame. Xiaomi, by contrast, uses the Mi Fit app (or Zepp Life for new models), which is simpler and more intuitive. The main plus is automatic synchronization with the Mi Band, Mi Watch and other ecosystem gadgets. But there is a downside: Xiaomi does not export data to Apple Health (unlike Picooc).
- 📱 Picooc App: Detailed analytics, Apple Health support, but complex interface and synchronization bugs.
- 🌐 Mi Fit/Zepp Life: Simple design, integration with other Xiaomi devices, but no exports to Apple Health.
- 🔄 Cloud storage: Picooc has data stored on the company’s servers (risk of leakage), Xiaomi has a binding to the Mi Account (you can download the archive).
💡
If you’re using an iPhone and Xiaomi scales, install a third-party Mi Scale app (unofficial) – it can export data to Apple Health, which the original Mi Fit doesn’t.
4. Design and usability: what to look for?
Smart scales are in the bathroom or bedroom, so their appearance and convenience matter. Picooc offers a more premium design: a glass surface with backlight, metal inserts and a thin body. Xiaomi, especially in budget models, looks simpler - a plastic case, a minimalist screen (or its absence in the Smart Scale 2).
Xiaomi’s usability is more straightforward: the Mi Body Composition Scale 2 is automatically set to start, while the Picooc S3 requires pressing a button or touching a sensor. Xiaomi also has a better user recognition feature – scales determine who is standing by weight and bioimpedance (more precisely than Picooc, where you sometimes have to confirm the profile manually).
⚠️ Note: If you have people in your family with a weight difference of less than 5 kg (for example, spouses with similar build), the scales may confuse their profiles, in which case it is better to choose a model with manual switching of users or adjust the recognition by the time of weighing.
5. Price and Price/Quality: Which is Better?
Xiaomi traditionally wins at the price: their scales are cheaper by 30-50% with comparable functionality. For example, Xiaomi Mi Body Composition Scale 2 costs about 3000-3500 ₽, while Picooc S5 It'll cost 5,000 to 6,000. ₽. But it is important to understand what you are paying for:
- 💰 Picooc S5: premium design, 4 electrodes, advanced analytics (cell viscosity, protein mass) suitable for athletes and those willing to pay for detail.
- 💵 Xiaomi Mi Body Composition Scale 2: Optimum Price/Quality, Stable Measurement, Integration with the Mi Home Ecosystem.
- 🪙 Budget models: Picooc S3 Lite (~2 500 ₽) Xiaomi Smart Scale 2 (~1 800 ₽) They lose exactly, but are suitable for basic weight control.
If you need scales for many years, pay attention to the warranty period and availability of spare parts. Xiaomi has it easier – their scales are sold officially in Russia, whereas Picooc often have to order from AliExpress, which complicates the service.

6. Which scales would be better for?
The choice between Picooc and Xiaomi depends on your goals.
- 🏋️ For athletes and bodybuilders: Picooc S5 — Because of the advanced analysis of muscle mass and cell viscosity, the data is not perfect, but it's useful for tracking dynamics.
- 👨👩👧👦 Families with children: Xiaomi Mi Body Composition Scale 2 - reliable user recognition, mode for pregnant women, simple interface.
- 💼 Office workers: Xiaomi Smart Scale 2 – a budget option for basic weight control without unnecessary features.
- 🍏 To iPhone users: Picooc S3 Lite – only this model from the budget synchronizes with Apple Health.
If you're in doubt, try this life hack: buy a low-cost Xiaomi Smart Scale 2 to start with. If you realize that you need more accurate data in a month, buy a Picooc S5 and compare the figures. Many users find that the difference between 2 and 3 thousand rubles does not justify itself.
Why Xiaomi’s cheap scales can be more accurate than the expensive Picoocs?
7. Frequent problems and how to avoid them
Smart scales are not ideal devices, and here are the typical user complaints and ways to address them:
- 🔋 Libras don't turn on or discharge quickly: Picooc often fails in 1-2 years, so you can only use the original charging cable. Xiaomi solves the problem by replacing batteries (AAA).
- 📱 Not synced with the app: check if Bluetooth is on on your smartphone and if the app is updated. For Xiaomi, reinstalling Mi Fit sometimes helps.
- ⚖️ Indications "jump": weigh at the same time (preferably in the morning on an empty stomach), bare feet and on a hard surface (not on the carpet).
⚠️ Note: If the scales show an unrealistically low percentage of fat (for example, 5-8% in a person with normal build), chances are you have mistyped height or gender in the profile!
1. Weigh yourself at the same time of day (optimally - in the morning after the toilet).
2. Use scales on a hard surface (tile, laminate), and not on the carpet.
3.Do not weigh yourself after intense training or bathing procedures - hydration levels will skew results.-->
