How to check the Xiaomi Redmi phone for authenticity: 7 ways

The mobile market is full of popular brands, and Xiaomi is no exception: Chinese replica manufacturers have learned to create external copies of flagships with amazing accuracy, repeating the packaging design, configuration and even the system interface. However, the internal stuffing of such devices is often outdated components, leading to fast discharge, slow operation and lack of warranty support.

Unscrupulous sellers can pass off fakes as originals, especially in open-market marketplaces or in dubious points of sale. A buyer who does not know the subtleties risks getting a device with a low-resolution screen instead of AMOLED, a weak processor and a fake camera that shoots worse than phones from a decade ago.

In this article, we will discuss all available methods of verification, from visual inspection to complex technical tests through the engineering menu, you will learn how to break the serial number on the official website, what codes to enter into the “caller” and what to look for when you first turn on. The only way to get a 100% guarantee is to buy from official partners, but even in this case, a basic check will not hurt.

Visual assessment of the quality of assembly and packaging

The first thing that a customer encounters is a box: Xiaomi's original packaging is made of dense cardboard with a clear, bright print. Forgeries often have blurry logos, font errors or color mismatches. Notice the technical information sticker: it's flat on the original, with a readable barcode and IMEI, which matches the number on the case.

The build quality of the smartphone itself will also tell a lot about its origins. In the original Redmi and Poco, the gaps between the screen and the frame are minimal, all buttons have a clear, quiet click without backlashes. Copies are often sinned by a creaking body, the protruding camera module or the uneven fit of the glasses. If you see glue around the lens or slits into which you can drive the nail, this is an alarming sign.

The kit is another important indicator. The standard set usually includes a USB cable, a SIM tray clip and documentation. The charger may not be available in new models, but if it is, it has a matte surface, smooth seams and clear power labeling. Cheap power supplies from a fake kit are often glossy, “cheap” plastic and lightweight, which indicates poor internal filling.

⚠️ WARNING: If the box has "Android" in large letters on the front, you're 100% fake. Xiaomi never uses the Android logo on its device packaging.

Check the ports and connectors. USB-C Or Micro-USB is sitting tightly in the case, the contacts inside are smooth and shiny. In replicas, the connector may stagger, be skewed, or have oxidation marks already on the new device. SIM-maps: in the original models, it often has a rubber seal to protect against moisture, which is either absent in copies or made of rigid rubber that does not provide tightness.

Checking IMEI and serial number on the official website

The most reliable software method is to match the device's IDs with the manufacturer's database, and every legal smartphone has a unique identity. IMEI (You can find it on the sticker at the back of the case, in the tray for the mobile phone. SIM-maps (on some models) or system settings. For quick access to information in the dial menu, enter the *#06 combination#.

Once you receive the code, go to the official Xiaomi Verification Portal, enter the number in the appropriate field, the system should display the device model, activation date and warranty status. If the site writes “Invalid” (Incorrect) or shows a model different from yours (for example, you bought a Redmi Note 10, and the site identifies some Mi 5), then the device is unoriginal or assembled from counterfeit parts.

It's important to understand that fraudsters have learned to fake IMEIs, too. They can rewrite a number from the original device to a fake, so if a site shows Activated status years ago or a date that doesn't match your purchase, that's a reason to think. In some cases, the same IMEI can be broken thousands of times, which is also a sign of cloning.

Analysis of MIUI operating system and interface

The interface is the face of a smartphone, and it's very hard to fake it one-to-one. The original MIUI (or HyperOS) shell has specific animations, fonts and features. Fakes often use stock Android with a deliberately set theme that mimics MIUI. Notice the smoothness of transitions: originals work fast, copies are often slowed down even on the menu.

Check for branded apps. The original pre-installed services are Google, Mi Cloud, Mi Browser, Mi Video and other proprietary Xiaomi apps. Forgeries may be missing, replaced by analogues or not running at all. Try logging into your Mi Account: if the system gives a server error or does not accept the correct password, this is a sign of a modified firmware.

Go to Settings → About Phone. This should show you the details: MIUI version, Android version, processor, RAM and ROM. Click a few times on the MIUI logo, the original will run animations with changing versions of Android. In the fakes, either nothing happens, or a link to the site in the browser will open.

Another marker is advertising: Global firmware versions for some regions may have ads in system applications, but they are native and correctly displayed. In fakes, ads can be sewn into the system level, popped up in random places, have a strange format, or lead to Chinese resources that are not relevant to your region.

Use of the engineering menu and USSD-code

For deep diagnostics, engineers and advanced users use hidden menus, which can be entered through the standard dialing interface. One of the most useful codes is ##6484## (or #4636##), which opens the CIT (Customer Information Test) menu, where you can check the operation of all the modules: screen, sensor, cameras, speakers, vibration, GPS and sensors.

In the testing menu, select the screen check point.Original Redmi displays (especially AMOLED) They have high pixel density and color reproduction, and the test will help to identify broken pixels or uneven backlights, which is often found in cheap ones. LCD-You can also check the multi-touch matrices that replace the originals in the fakes. 10 touchpoints, counterfeiting is often limited 2-5.

Code ##4636## opens the phone information menu, and you can see uptime, network status, and connection details, and if you see numbers in the "Last Reboot Time" column that don't match your actions, or fields filled with zeros/unknown values, that's a sign of firmware bugs.

Not all codes work on all firmware versions. In new security updates, Xiaomi may block access to some engineering features for ordinary users. If the code doesn’t work and just disappears from the dial screen, try downloading the Device Info HW or CPU-Z app from Google Play. They will show the real “stuffing” of the device that is difficult to fake at the software level.

Comparison of technical characteristics and performance

The most obvious way to distinguish fake is to compare claimed characteristics with real ones «8 GB of RAM and 256 GB of memory, although inside is a budget chipset with a 2 GB of RAM. Use the AnTuTu Benchmark or Geekbench app. Original Redmi Note 12 Pro's gonna be about 500-600 Thousands of points, while the fake barely reaches 100 thousand.

Note the detail in the benchmark reports. They will show the real name of the processor (e.g. Snapdragon or Dimensity), screen resolution and camera model. If the report says 720p screen resolution instead of 1080p or 1200p, or MediaTek processor instead of Qualcomm (or vice versa if it doesn’t meet the model specification), you’re a fake.

The table below will help you quickly navigate the typical inconsistencies between the original and the replica of popular models:

Special attention is paid to the camera. Counterfeiting often has a cheap 2 MP module that programmatically stretches the image to 48 or 64 MP. Take a photo in good light and under insufficient light. The original will take a clear shot with noise only in the dark, and the fake will give a porridge of pixels even in the daytime. Also check the zoom: optical zoom in budget models is not, but digital zoom on the original works softer.

Checking the battery and charging speed

The battery is one of the most expensive components, so it is saved first. Xiaomi's original batteries have overheating protection, fast-charging controllers and real capacity close to the declared. 2000-2500 MAC, even if the body is written 5000 mic.

You can check the status of the battery through applications like AccuBattery or Ampere. Install the application, discharge the phone to 15-20% and charge the original cable and unit. Original devices support the Quick Charge or Power Delivery protocols, which is reflected in the application (for example, the status of "Charging fast"). Counterfeit charge with normal current (0.5 - 1.0 A) even from a powerful unit.

Note the discharge rate. If a new phone is running for 3-4 hours at an average load instead of the 7-9 hours claimed, it is a sure sign of an old or defective battery. Also, the originals rarely warm up during normal operation (social networks, videos), while counterfeits can get hot after 15 minutes of use due to inefficient processor and poor optimization.

⚠️ Attention: Bloated battery is a sign of defect or counterfeit. If the back of the phone starts to move or the screen is pushed out of the frame, immediately stop using the device!

It is important to use the same power supply and cable that came with the kit (if any). Sometimes the fake is sold with left-hand charging, which can not unlock the potential of even a normal battery. But if you connect a powerful unit (for example, from a laptop or a flagship) and the speed does not increase, the problem is the controller of the phone.

Where to buy and how to protect yourself

The best protection against counterfeiting is the right place to buy. Official stores, large chain retailers and authorized Xiaomi partners value their reputation and will not mess with counterfeit. When buying on marketplaces, choose sellers marked “Official Store” or high ratings and a lot of real reviews.

When buying from hand (Avito, OLX), the risk of getting a fake is maximum. Meet in crowded places where there is Wi-Fi to immediately check the device. Don't settle for a "sealed" box at a price well below the market. There are no miracles: no one will sell the new Redmi Note 13 for half price unless it is stolen or fake.

Keep checks, warranty cards and screenshots of correspondence with the seller. These are your main trump cards in the case of return of goods. If you order from abroad (AliExpress, eBay), be sure to shoot video unpacking, this proof will help win the argument if a brick or a copy comes.

Remember, even a box, a film, and all the documents don't guarantee authenticity. Chinese craftsmen have learned to copy all the attributes of the original, including holograms and other documents. QR-Only a comprehensive check of hardware, software and external features will give an accurate answer.
