Previous articleThe original Xiaomi battery or fake? 7 ways to check with photos and videos

The battery is one of the most vulnerable components of Xiaomi’s smartphone, which loses capacity over time and needs to be replaced, but the market is flooded with fake batteries that not only fail faster, but can cause overheating, bloating or even fire. According to Counterpoint Research, up to 30% of Xiaomi’s batteries sold on marketplaces are counterfeit. How to avoid getting a fake and buy an original battery? In this guide, we will discuss 7 reliable ways to check, including packaging analysis, QR-codes, serial numbers, and even charging behavior.

Fakes are often disguised as originals, copying packaging designs, stickers, and even holograms, but there are details that you can’t fool — from specifications (capacity, voltage) to branded markers on the battery case, we show you what to look for when buying a new battery for Redmi Note 12, POCO X5, Mi 11 and other models, and also tell you how to check the battery after installation, because some fakes only show themselves in operation.

Important: Even if you buy a battery from a Xiaomi store or a trusted seller, the risk of a fake battery is still there, for example, in 2023, AliExpress discovered counterfeit batteries with fake batteries. QR-So multi-step verification is the only way to guarantee originality.

1. Packaging check: 5 signs of forgery

Xiaomi's original batteries come in branded autopsy-protected packaging. Counterfeit batteries are often packed in low-quality boxes, with blurry fonts or inaccurate colors.

• 📦 Material box: the original - dense cardboard with matte coating, fake - thin paper or glossy surface.
• 🔍 Hologram: on the original packaging, the hologram changes color when tilted (green) → Blue, fakes have static or no.
• 🖋️ Fonts and inscriptions: check the accuracy of the Xiaomi logo (the letter "i" without a dot) and the absence of spelling errors (for example, "Made in Chaina").
• 🔢 Serial number: the box and battery must match (more on this in the next section).
• 📏 Box sizes: original packaging for Redmi Note and POCO have standard dimensions (for example, 10 × 6 × 1.5 see for Redmi Note 10).

Pay special attention to the label with QR-The original package is located on the end of the box and contains a unique code that can be checked through the official Mi Verify app (available for Android and iOS). QR-codes or codes leading to fake websites.

⚠️ Note: Some vendors repackage fake batteries into original boxes from other components (such as chargers). Always check that the battery model matches your smartphone - the box should have the exact name (such as the exact name, BM4B For the Redmi Note 11).

Serial number and QR-Code: How to verify authenticity

Each Xiaomi battery has a unique serial number (S/N) and QR-This is a code that is duplicated on the box and the battery itself, and you can check it through the official brand services:

1. Find the serial number on the battery sticker (format: 16 characters, for example L1A2B3C4D5E6F7G8).
2. Scan it. QR-code through the Mi Verify application or any QR-scanner.
3. Go to mi.com/global/verify and enter the serial number.
4. Verify the data: information about the battery model, date of production and status of "Original" should be displayed.

If the site is a bug or the data doesn't match your smartphone model, it's a fake.

• 🔄 QR-The code leads to a third-party site (e.g., Alibaba or an unknown domain).
• 📅 The production date on the Xiaomi website does not match the date on the box (the difference is more than 1 month).
• 🔢 The serial number begins with the numbers 0 or 9 – this is a typical sign of fake.

An example of the original QR-The Redmi Note 12 Pro+:

https://verify.mi.com/?sn=L1A2B3C4D5E6F7G8&model=BM4G

Fake codes often contain redundant characters or lead to shortened links (such as bit.ly or tinyurl.com).

External inspection of the battery: 6 parts that give a fake

Even if the packaging and QR-The code looks authentic, look at the battery itself. Xiaomi's original batteries have clear quality markers that are hard to fake:

Note the production date (YYYY-MM-DD.) If the battery was released more than 6 months ago, its capacity could have decreased significantly even before installation. Xiaomi's original batteries have a shelf life of no more than 1 year in unused condition.

4. Technical parameters: capacity, voltage and resistance

Fake batteries often have low specifications, for example, instead of the declared 5000 mAh, the real capacity may not exceed 3000-3500 mAh.

Method 1: Software verification (for installed battery)

• 📱 Install the AccuBattery app (for Android) or AIDA64.
• 🔋 Start a full discharge-charging cycle (0% to 100%).
• 📊 Compare the actual capacity with the passport (permissible deviation: no more than 5%).

Method 2: Multimeter test (for a new battery)

1. Set the multimeter in voltage measurement mode (DC, 20V).
2. Connect the probes to the battery contacts (+ and -).
3. The voltage of the original Xiaomi battery should be in the range of 3.7-4.4 V (for lithium-polymer batteries).
4. If the voltage is below 3.5 V or above 4.5 V, the battery is defective or fake.

You can also measure the internal resistance of the battery (this requires a specialized tester, for example, YR1035). In the original Xiaomi batteries, the resistance does not exceed 100-150 mOhm, for counterfeits it can reach 300-500 mOhms, which leads to rapid heating and reduced operating time.

💡

If you don't have a multimeter, go to Xiaomi's service center, where they'll check the battery settings for free before you buy it, which will take no more than 10 minutes, but will save you the risk of buying a fake.

5. Charging behavior: how a fake reveals itself

Even if the battery has passed all previous tests, its charging behavior can be counterfeit. Xiaomi’s original batteries support proprietary fast charging technologies (Fast Charge, HyperCharge), which are often fakes, but not implemented correctly.

• ⚡ Charging speed: the original battery for the Redmi Note 12 Pro+ (120W) It charges up to 50 percent in 10 to 12 minutes, and it charges up to 2-3 times slower.
• 🔥 Heating: if the smartphone case is heated above 40°C when charging is a sign of high internal resistance (typical for fakes).
• 📉 Capacity drawdown: after 2-3 charging-discharge cycles, the original battery loses no more than 1-2% of capacity, the fake one - up to 10-15%.
• 🔄 Unstable voltage: if the smartphone spontaneously turns off at 10-20% charge, the battery is not original.

For a precise analysis, use the Battery Guru app (available on Google Play), which captures the voltage and charging current charts, the original batteries have a smooth schedule, without any sudden jumps, and a fake battery graph example:

⚠️ Attention: Some fakes simulate fast charging at the firmware level, showing false values in the smartphone interface. To check this, connect your smartphone to your PC and use the USBDeview program to show the real power of the current.

6. Check through official Xiaomi services

The most reliable way to confirm originality is to contact the Xiaomi service center or use official brand tools.

• 🏢 Offline check: Xiaomi’s branded service centers have special scanners for checking batteries. The service is free, takes 5-10 minutes.
• 🌐 Mi Verify Online Service: Upload a Photo QR-battery code to the site mi.com/global/verify.
• 📞 Hotline: Call the number 8 800 775-66-99 (for Russia) and name the serial number of the battery - the operator will confirm the authenticity.

If you buy a battery on AliExpress or other marketplaces, ask the seller for a video check through Mi Verify.

I want to make sure the originality of the product is before I buy it.


Please make a video like you:




1 Unpack the battery on camera (see box and stickers).




2. Scan the QR-code through Mi Verify and show the result.




3. Verify the serial number on the box and battery.




Thank you!

💡

If the seller refuses to provide a video with verification or offers a “guarantee of originality” without proof, this is a reason to doubt the honesty.

7.Where to buy the original battery: proven sources

Even though you know all the ways to test, you still run the risk of getting a fake if you buy a battery in a place that is not safe, and here are the official and proven sources for buying Xiaomi’s original batteries:

Avoid buying on Avito, Yule, or small repair shops, where you are more likely to get caught in a counterfeit, and if you buy a battery for an older model (like the Redmi Note 5), ask the seller if the product is reconditioned, which is cheaper, but their capacity is already reduced by 20 to 30 percent.

Important: Since 2023, Xiaomi has been labeling the original batteries with a special hologram with the microtext "MI AUTHENTIC", which is visible only under the magnifying glass.
