The battery is one of the most vulnerable components of Xiaomi’s smartphone, which needs to be replaced after 2-3 years of active use. However, the market is flooded with fakes that not only fail faster, but can explode, overheat or damage the motherboard. According to Counterpoint Research, up to 40% of Xiaomi’s batteries sold on marketplaces are counterfeit. How not to run into fake and buy an original battery? In this guide, we will analyze 12 reliable methods of verification, including visual signs, software tests and even physical measurements.
Fakes are often disguised as originals, with packages, stickers and even serial numbers copied, but there are details that can’t be fooled, from the quality of the contacts soldered to the smartphone’s response to an uncertified battery. We have collected unique features that fake producers cannot reproduce (for example, a specific font on the original stickers or hidden fonts). QR-You will also learn what tools you will need to verify and how to avoid cheating when buying used batteries.
1.Packaging: 5 parts that give off a fake
Xiaomi's original batteries come in branded autopsy boxes. Counterfeit packages often differ in print quality, materials, and even smell.
- 📦 Xiaomi logo: The original box is convex (embossed) rather than just printed. Counterfeiters often use flat printing with blurred edges.
- 🔍 Serial number: Must match the number on the battery itself. On fakes, these numbers often don't match or are printed in a different font.
- 🖼️ Hologram: Originals have a holographic transfusion-effect sticker that changes color when tilted.Fakes use regular foil.
- 📏 Box sizes: Original packaging for Redmi Note 10 Pro sizes 15.5 × 8.5 × 1.2 see the deviation more than 2 mm, fake sign.
- 💨 Smell: New original boxes smell like cardboard without chemical impurities.
Special attention is paid to the barcode. On the original packaging, it is laser-coded and has clear boundaries, whereas on counterfeits, it is a regular print with blurred lines. You can verify authenticity through the Xiaomi Authenticity Check app (available on Google Play), by scanning the code.
Battery sticker: fonts, codes and hidden tags
The most reliable way to distinguish the original is to examine the sticker on the battery itself.
- 🔤 Font: Originals use MiSans font (designed by Xiaomi) The letters "M" and "i" in the word "Mi" on fakes often have serifs or uneven lines.
- 📊 QR-Code: There are two on the original sticker QR-One leads to Xiaomi's support page, the other contains batch data, and fakes often have broken codes or are redirected to suspicious sites.
- 🔢 Serial number: It should start with letters MDY (for models 2022-2026) or M20 (Forgeries use random combinations of the type XM12345.
- 🎨 Color palette: Orange warning stickers on originals have color code #FF6B00, And on fakes, it's a dimmer shade (#FFA500).
For verification QR-Use the standard camera app on Xiaomi smartphone, which automatically recognizes codes and shows hidden information. If the code is not read or leads to an error page, you have 100% forgery.

Physical parameters: weight, dimensions and materials
Xiaomi’s original batteries are made with strict quality control, so their physical characteristics are stable, and counterfeits often save on materials, which can be detected by simple measurements:
| Parameter | Original (e.g. Redmi Note 11 Pro+) | Fake (typical deviations) |
|---|---|---|
| Weight. | 48.5 ± 0.3 g | 45–52 g (often lighter due to cheap materials) |
| Thickness | 3.85 mm | 3.5 to 4.2 mm (uneven edges) |
| Materials of contacts | Nickeled copper (brilliant, without scratches) | Common copper (dull, quickly oxidized) |
| Stiffness of the hull | It is tight, does not buckle when pressed. | Soft, finger-pressing. |
Use electronic scales (with an accuracy of 0.1 g) and a barbell for accurate measurements. Pay special attention to contacts: the originals have perfectly flat edges and are covered with a protective layer, while counterfeits often show signs of soldering or corrosion.
💡
If you don’t have a bar, use a ruler and coin: the original Xiaomi battery should be thinner than a 5-ruble coin (4 mm thick).
4. Smartphone Check: Hidden Commands and Diagnostics
Xiaomi can recognize the non-original battery itself through the service menu.
- Open the Phone app and enter the combination: ##4636## Select Battery Information.
- Check the battery health field. The original will show a value of 95-100%, a fake - less than 90% or an Unknown error.
- Enter another command: ##6484### From the MBTest menu, select Battery Info. The original battery will display manufacturer data (e.g. ATL or SDI), fake - empty field or random characters.
If the smartphone gives a warning: an uncertified battery when turned on, it is a complete sign of a fake, and in some cases, the phone may even refuse to charge or limit the maximum current to 500 mA.
💡
Even if the battery looks like the original, but the smartphone does not recognize it – it is fake. Xiaomi manufacturers have been integrating authentication chips into batteries since 2019.
5. Heating and charging test: how the fake reveals itself
Fake batteries often warm up more than the original ones because of the poor quality of the cells.
- Charge your smartphone to 100% original charger (power at least 18 watts).
- When charging, measure the battery temperature in 30 minutes. Use an infrared thermometer or the AIDA64 app.
- Compare the results: 🔥 Original: The temperature does not exceed 38°C. ⚠️ Fake: Heating above 45°C (risk of swelling!).
Another test is to check charging time: the original Xiaomi 5000 mAh battery (for example, in the Poco X3 Pro) charges from 0 to 100% in 1 hour 40 minutes when using a 33 W charge. Counterfeit charges longer (2.5-3 hours) or show an unstable percentage (for example, “jumps” from 80% to 60%).
Use the original ZU|Charge at room temperature (20–25)°C)|Check the temperature in 30 and 60 minutes.|Compare with the reference values for your model-->
6. Check through official Xiaomi services
Xiaomi provides two official ways to verify battery authentication:
- Serial number verification site: Go to the authentication page. Enter the serial number from the battery sticker. The original will show Genuine status, a fake is Invalid or an error.
- Mi Verify app (available for service centers): Scanner QR-Check the authentication chip through the battery. NFC (Special equipment is required).
Important: Xiaomi may not recognize batteries released for specific regions (such as Indian or Chinese versions), in which case contact the official service center to check the battery through the diagnostic software Mi Flash Pro.
💡
If you buy a battery on AliExpress, ask the seller to check the serial number on Xiaomi’s website before paying.
7.Price and place of purchase: how not to run into a fake
The cost of the original Xiaomi battery depends on the model, but always kept within certain limits:
| Smartphone model | The cost of the original battery (2026) | Typical price of a fake |
|---|---|---|
| Redmi Note 12 Pro+ | 2 200–2 500 ₽ | 800–1 200 ₽ |
| Xiaomi 13 Lite | 2 800–3 200 ₽ | 1 000–1 500 ₽ |
| Poco F5 | 2 000–2 300 ₽ | 700–1 100 ₽ |
Counterfeit products are often sold 30 to 70 percent cheaper than the original.
- ❌ "Original, but without the box" (often repackaged fakes).
- ❌ "High-capacity battery" (originals always correspond to the declared capacity).
- ❌ "100% compatible" (without serial number).
Buy batteries only from official service centers or from trusted sellers on Wildberries/Ozon with a rating above 4.9. Avoid AliExpress and local markets, where the probability of running into fake is more than 60%.
💡
Before you buy, check the reviews of the seller for the keywords: "swelled up", "does not hold charge", "the phone does not see." These are sure signs of fakes.
8 What to do if you have already purchased a fake?
If you find that you have installed a fake battery, act quickly:
- Stop using: Remove the battery (if possible) or turn off the smartphone.
- Check for bloating: Put the battery on a flat surface. If it's swaying or not flat, it's a sign of deformation.
- Dispose of the battery correctly: Don't throw it in the usual garbage! Take it to the battery reception point (e.g., Ecotech or MegaFon).
- Return the money: If you bought it on the marketplace, make a refund for “non-description.” Enter a photo of the tests (for example, a screenshot from # #4636###).
⚠️ Warning: Fake batteries can ignite when charged with Quick Charge (Turbo Charge) if your smartphone supports fast charging but the battery is heated after 10 minutes, turn it off immediately!
If the smartphone starts to spontaneously reboot after installing the fake, or if it shows a Battery over voltage error, it means that the power controller is damaged, in which case a diagnosis is required at the service center - further use is not safe.
