Modern smart scales have become an integral part of the Smart Home ecosystem, allowing you to track not only weight, but also the percentage of fat, muscle mass and water in the body. However, the huge popularity of the Xiaomi brand has spawned many copies that are almost indistinguishable from the original, but have questionable measurement accuracy and often do not connect to the application. Customers often face a situation where the device looks presentable but refuses to work correctly through official software.
In this article, we will discuss detailed methods to determine the authenticity of a device before you buy it or immediately after unpacking it. You do not need to be an expert in electronics to notice obvious discrepancies as materials or software. We will look at physical features, packaging features, nuances of the Mi Home application and technical characteristics that cannot be forged in artisanal conditions.
The company's original products are always accompanied by a strict quality control system, which is reflected in every step of the interaction with the gadget. From the font at the bottom of the case to the algorithms for synchronizing with the smartphone, all the details matter. Ignoring these little things can lead to the purchase of a useless accessory that only takes up space in the bathroom.
Packaging and labelling analysis
The first thing you encounter when you get a product is packaging. Xiaomi's original boxes are made of thick, matte cardboard of high quality that doesn't get nicked by easy pressing. The fake cardboard is often looser, more glossy, or has an uneven shade of white. Notice the ends of the box: the original one is always perfectly smooth, with no glue marks or facet discrepancies.
On the back of the box is a label or a stamp directly on the cardboard, and it must show the model of the device, the power supply, the country of origin and, most importantly, the serial number (SN) and QR-The font on the label should be clear, without floating letters or blurred paint. Forgeries are often spelling errors in the English text or miswriting of the company name (for example, Xoaomi or Xaiomi).
⚠️ If the package is completely missing information in English or, conversely, there are no Chinese characters (for global versions), this may indicate a “gray” origin of the product or outright fake.
Pay special attention to protective film. The original scales often come in a sealed shrink film with perforation for opening or neat stretch film. If the device is simply nestled in a box without protection or packaged in a cheap rustling bag, it is an alarm. The print quality of the Mi logo should also be flawless: no extra dots, blurred edges or uneven color.
Appearance and quality of materials of the body
The tactile sensations and visual inspection of the device itself provide a wealth of information about its origins: tempered glass used in original models like the Mi Body Composition Scale 2 should be perfectly smooth, without air bubbles under the surface and distortion. The finger should slide easily, without delay. Cheap copies often use regular plastic with a spray that can be erased over time, or low-quality glass with visible defects.
Turn the scales over and look at the bottom, and there are anti-lip legs, battery compartments and information engravings, and the original leg is made of thick rubber that is odorless and firmly fixed, and in the battery compartment, the contacts must be of quality metal (often brass color), not of fine spraying that oxidizes after a week, and the compartment cover should close with a clear click, no backlashes and no gaps.
The information engraving on the bottom is the device's passport. The text must be laser-painted or with a quality print that is not erased by the nail. Here are the model, the input voltage, the maximum load and the Mi logo. In fakes, this text is often painted with paint that can be lubricated, or the font is different from the brand's corporate identity. Also check the screws: in the originals they are always recessed and closed with decorative caps or have a single hat.
💡
Spend your nail on the edge of the platform: in the original, the transition between the glass and the plastic case is almost imperceptible, whereas in fakes, a sharp edge or glue is often felt.
Checking through the Mi Home app
The most reliable software way to test originality is to try to connect the device to the Xiaomi ecosystem. The original scales support direct synchronization with the Mi Home app (or Zepp Life for older models). The connection process is automatic: just turn on Bluetooth on your smartphone, open the application and click "Add device." The system will find the scales and suggest that they be tied.
If the application does not see the device, offers to download third-party, unknown software or requires the input of any activation codes through suspicious sites, you are a fake. Xiaomi's original scales do not require complex manipulations for initial configuration. Once connected, the application will display the exact model of the device, the firmware version and the ability to update the software. The lack of the ability to update the firmware (Firmware Update) is a sure sign of a non-original gadget.
The functionality in the app also plays a role. The original scales convey up to 13 body composition parameters, plot changes, allow you to create profiles for different family members, and even determine body balance. If the app only shows weight and nothing more, or the interface looks "crooked," with untranslated fragments or layout errors, it's a copy. Body analysis algorithms are intellectual property that Chinese factories rarely copy one-to-one.

Technical characteristics and accuracy of measurements
The interior is what distinguishes a smart gadget from a conventional mechanical platform. The original scales use high-precision manganese copper strain gauges that provide measurement error of no more than 50 grams. Counterfeits are often equipped with cheap sensors that can “lie” 300-500 grams or more, making it impossible to track progress. In addition, the original begins measuring weight at a minimum displacement (from 50 grams), while copies can ignore light weight or, conversely, spontaneously turn on.
The original Xiaomi scales run from standard batteries (usually 4xAA) to 12 months in active use thanks to optimized sleep algorithms. Cheap counterparts can eat a set of batteries in 2-3 weeks due to an inefficient power management scheme. Also note the screen: in the original, the numbers light up evenly, have bright but not blinding backlighting and the right segmentation.
| Characteristics | Original Xiaomi | Fake/Copy |
|---|---|---|
| Weight error | ± 50 g | ± 300-500 g or more |
| Battery life | 6–12 months | 2–4 weeks |
| Connection to Mi Home | Automatic. | Not available or through third-party software |
| Platform material | Tempered glass | Plastic or glass |
| Number of measured parameters | Up to 13 indicators | Only weight (sometimes BMI) |
⚠️ Note: If the scales show the same result when weighing different people with a significant difference in weight, this is a sign of a malfunction of strain gauges, which is characteristic of defective copies.
Serial number and QR-code: authentication
Each Xiaomi device has a unique identifier. QR-code that duplicates the serial number (SN). Once you scan this code with your smartphone camera (without connecting to the app), you should get a character string corresponding to the number on the sticker. In the original products, this code is read instantly and clearly. In counterfeits, the code may be unreadable, lead to a blank page, or contain a set of random characters.
You can try to check the serial number on the official Mi Verify website (although support for this feature for weights can vary depending on the region). The easiest way is to compare the number on the device, on the box and in the Mi Home app after you connect. All three values should match perfectly. The number discrepancy is a hundred percent sign that the device was assembled from different parts or it is a refabricate (restored artisanal goods).

Comparison of price and place of purchase
Price may not be the only criterion, but it is an important indicator: It costs money to produce quality smart scales with accurate sensors and a Bluetooth module. If you see an offer that is 30-40% or more cheaper than the average market price, the probability of encountering counterfeit goes up to 90%. Xiaomi adheres to a low margin policy, but does not sell its products below the cost of components.
Place of purchase also matters: Official dealers, large electronics stores and authorized sellers on marketplaces value reputation and provide a guarantee. Buying “hand-to-hand” on a vending machine or in dubious stalls without a check and warranty card significantly increases risks. Original goods are always accompanied by a warranty card (often electronically) and instructions in several languages, including Russian (for the EAEU).
The manual is another element worth looking at: the original is a brochure with good quality printing, clear diagrams and proper translation. In copies, the instructions are often printed on thin gray paper, with blurry pictures and machine translation that cuts the eye. The lack of Russian instructions in a product intended for sale in Russia is also a violation worth noting.
💡
Low price + no warranty + sale in an undisclosed place = high probability of buying a fake. The savings of 500 rubles are not worth losing nerves and inaccurate health data.
