Xiaomi’s smart scales are some of the most popular health gadgets, but their popularity has caught the attention of scammers. According to AliExpress and Wildberries, up to 30% of Mi Smart Scale devices on the market are counterfeit. Counterfeit not only distorts weight and body composition, but can also pose dangers, from poor-quality materials to data leakage through uncertified software.
In this article, we will analyze 7 working methods for checking originality, including hidden marks on the case, analysis. QR-You will learn what parts of the package will never be forged by fraudsters, how to recognize a clone by a serial number and why even visually identical scales can give false data. From the budget Mi Body Composition Scale 2 to the premium Xiaomi Smart Scale 3.
1. Packaging check: 5 parts that can not be faked
The original Xiaomi box is the first and most reliable authentication indicator. Fraudsters often save on packaging materials, so pay attention to:
- 📦 Cardboard quality: the original uses dense matte cardboard with laminated coating. The fakes are usually glossy or rough to the touch.
- 🖨️ Logo printing: the original box has the Mi logo and Xiaomi embossed (convex letters) on it.
- 🔍 Barcode and QR-code: the back of the box must have a unique barcode (starting with 694 or 697) and QR-code leading to the official website of Xiaomi.
- 📝 Serial number: at the bottom of the box is a sticker with the serial number (format: 12 digits) + 2 letters. counterfeits are often missing or appear to be ABC123.
- 🌍 Instruction languages: the original box contains an 8-fold insert+ Clones usually only have English and Russian (often with errors).
Pay special attention to protective stickers: on the original Xiaomi scales, they have a holographic effect and tear at opening. Counterfeiters use conventional stickers or do not glue them at all.
⚠️ Note: If the box shows a net weight (e.g. 1.8 kg) but the actual weight of the device differs by more than 50 grams, it is 100% fake.The original Xiaomi scale weighs exactly 1.85 kg (±20g).
2. Serial number: how to check through official services
Each Xiaomi device has a unique serial number (S/N), You can check it out through the manufacturer's databases:
- 📦 On a sticker under the box (format: XXXX-XX-XXXXXX-XX).
- 🔧 On the back of the scales (under rubber legs).
- 📱 In the Mi Fit app (Section Profile) → My devices. → Weight settings).
To verify:
- Go to mi.com/global/verify.
- Enter the serial number and the captcha.
- If the device is original, the system will show the model, the date of production and the status of the warranty.
Alternatively, use the Mi Home app:
- Open the Mi Home and add the scales as a new device.
- At the connection stage, the system will automatically check the serial number.
- If you see an error "Device is not certified" - in front of you a fake.
What to do if the serial number does not pass the check?
| Sign. | Original | Fake. |
|---|---|---|
| Serial number format | 12 numbers + 2 letters (example: 1234567890AB) | Arbitrary set (example: XIAOMI-2026) |
| Location S/N | Under the box and on the scales. | Only on the box or not. |
| Checkup result on mi.com | Shows the model and date of production | The "Invalid" error SN" data from another model |
| Coincidence. S/N box-and-appendix | Identical. | Different or not in the appendix |
3. Visual differences: body, display and sensors
Even if the package and serial number look authentic, check the scales themselves. The original devices have a number of unique design features:
- 🔲 Body shape: Xiaomi's original scales have rounded corners of a radius of 3.2 mm (measure with a ruler.
- 🖥️ Display: The original has a screen IPS And they're all lighted up. TFT-lens-screen.
- 👣 Sensors: The original scales have 4 electrodes (2 large and 2 small) made of stainless steel.
- 🔋 Battery compartment: the original compartment cover is magnetic, with the Mi logo. The clones have a plastic latch or screws.
Conduct a weighting uniformity test:
- Put on the scale an object weighing 1-2 kg (for example, a bottle of water).
- Move the object over the surface of the scale.
- The original scale will show the same weight (±5 g), counterfeits - a difference of 20-50 g.
💡
If Xiaomi scales show weight to within 50g (e.g. 75.0kg instead of 75.23kg), that's a sure sign of fake.The original models display weights to within 10g for adults and 5g for infants.
Notice the numerical font on the display: the original uses the Mi Sans branded font with rounded digits. For fakes, the font is often similar to Arial or Roboto.
4. Check through the Mi Fit app: hidden parameters
The official Mi Fit app (or Zepp Life for new models) can give you a fake before you connect.
Download the application from the official website (not from third-party sources)|
Register a Xiaomi account (required!)|
Add the scales through Profile → Add the device|
Check the model name in the device settings|
Compare the serial number in the app and on the box-->
If the scales are connected, but:
- 📛 The model name in the app differs from the one on the box (for example, instead of Mi Body Composition Scale 2, the Smart Scale is displayed without the brand).
- 📊 In the section Analysis of body composition there are no parameters (muscle mass, bone mass, water).
- 🔄 Libras are permanently turned off or require re-synchronization.
- these are signs of a fake.
Pay attention to the connection protocol:
- Original scales use Bluetooth 5.0 with encryption AES-128.
- Fakes often work via Bluetooth 4.0 or even BLE 4.2 without encryption (checked through applications like nRF Connect).
⚠️ Note: Some fakes mimic the Mi Fit interface but send data to third-party servers. Before buying, check if the app requires access to Contacts or Locations - the original Xiaomi software only requests Bluetooth and Warehouse.
5.Accurity Test: How Counterfeiting Deceives Users
The main problem with clones is inaccurate readings.
- Bead test: Take an item with a known weight (like a 1kg pack of sugar) and weigh it on a scale.The original Xiaomi will show 1.00kg (±5 g), counterfeits - from 0.95 kg to 1.05 kg.
- Repeatability test: Weigh 5 times in a row without changing position. The range of readings of the original is up to 20 g, for fakes - up to 200 g.
- Body composition test: Compare muscle mass and fat readings with a professional analyzer (for example, in a fitness club).
Pay attention to the measurement algorithms:
- Xiaomi’s original scales use the method BIA (Bioimpedance analysis with 8 electrodes.
- Counterfeiting is often saved on sensors using 4 electrodes or simplified algorithms.
💡
If the scales show a fat percentage of less than 10% in a normal diet or muscle mass of more than 50% of body weight, this is a sure sign of fake. WHO and do not give such deviations.
For Advanced Verification, use the LibreScale app (available on GitHub):
- Connect the scale to LibreScale via Bluetooth.
- Run the Raw Data test.
- The original scales transmit 16 parameters (weight, impedance, temperature, etc.), fakes - 4-6.
6.A check on the QR-code: what the sticker hides
On the back of the original scales Xiaomi has QR-code that contains encrypted information about the device. Scan it with the help of:
- 📱 Standard Camera Scanner on iPhone or Android.
- 🔗 Annexes QR & Barcode Scanner or Kaspersky QR Scanner.
Original. QR-code should lead:
- Official page of the device: https://www.mi.com/global/....
- Authentication page: https://verify.mi.com/....
If QR-lead:
- 🛒 Shop Page (AliExpress, Amazon).
- 🔗 Shortened links (bit.ly, tinyurl.com).
- 📄 PDF-file.
- it's a fake.
Check the structure QR-code:
- The original code contains the encrypted serial number and hash sum of the model.
- Fake codes are often a simple textual link (e.g., a link, https://xiaomi-scale.com).
💡
If QR-The code is not scanned the first time, try holding the phone 10 to 15 cm away and turning on the flashlight. Xiaomi's original codes are printed at high resolution (600) DPI) They can be read even in low light.
