How to find out the year of release of Xiaomi Redmi 5: the full guide

Owning a Xiaomi smartphone often involves knowing the exact characteristics of a device, especially if you are planning to sell it, buy a used gadget or just want to understand the history of your device. The Redmi 5 model, released in late 2017, was a real hit due to its metal body and affordable price, but over time, data on the production date can be lost. Users often confuse the date of the model’s release on the market and the actual day of assembly of a particular instance, which leads to misunderstanding when assessing the state of the battery or residual life of the device.

There are several proven methods to establish the truth without going to the service center. The exact date of production is important not only for collectors, but also for those who buy a device from hand, because a lithium polymer battery has the ability to degrade even without active use. In this article, we will discuss in detail the software and physical ways of identifying the age of your gadget, and explain how to decipher complex factory codes.

Don’t rely on just one source of information, as data can be displayed differently in different delivery regions, and we’ll look at a combination of methods that will give you a 100% guarantee of getting the right information about your Redmi 5, which will help you avoid fraud in transactions and better understand the technical condition of your equipment.

Verification through the engineering menu and system settings

The fastest way to get the initial build date information is through the use of built-in MIUI system utilities. However, it is worth considering that the standard settings menu does not always display the full date in an understandable format, often limited to the model year.

You'll need to open the Phone app and dial a special character combination. Once you enter the #6484##, the CIT menu automatically opens on the screen. This is all the diagnostic data, including the hardware version and sometimes the component calibration date. Please note that on some global firmwares, this code can be changed or blocked by the carrier.

If the code didn't work, try an alternative path through standard settings. Go to Settings → About Phone → All settings. The MIUI version or Android version may contain indirect information, but the more reliable option is to search for a date in the Status section, which often indicates the year of release of the batch, although the specific day of assembly may be hidden.

It is important to understand that software data can be changed when the device is flashed by unscrupulous sellers. Therefore, the information from the CIT menu must be matched with physical markers. If the engineering menu date differs significantly from the expected one (for example, indicates the future or deep past), this can signal interference with the code.

💡

If the ##6484### code doesn’t work, try entering *#06# to check for IMEI, which also contains encrypted factory information.

Analysis of factory packaging and stickers on the body

The most reliable source of information about the date of production is the original box from the device. On the side or end of the cardboard packaging Xiaomi always has a white sticker with barcodes and text information. Look for a line labeled Date or Mfg Date, where in the format of GGYG-MM or GGYG/MM/DDD shows the exact day of the release of the device from the conveyor.

If the box is not preserved, carefully examine the smartphone itself. The back of the Redmi 5, which is made of aluminum, can also be marked, although on global versions it is often replaced by the brand logo. In some regions, especially in China and India, the model and year data are stamped on the bottom of the case in fine print.

Notice the status of the sticker: if it's overstuffed, has autopsy marks, or the data on it doesn't match the information in the system, it's a warning sign. The original label is flat, bubble-free, and the text is clearly printed. The factory marking is the first step in testing when you buy a used device.

In the absence of external signs, you can try to carefully remove SIM-Sometimes, though rarely, there may be microscopic marks under or near the tray, but this method is more expertly evaluated and requires a magnifying glass.

Transcription IMEI-code and serial number

Each mobile phone has a unique identifier — IMEI (International Mobile Equipment Identity, which is 15 digits long and contains encrypted information about the manufacturer, model and batch. Redmi 5 has two main features. IMEI, The device supports two SIM-maps, and they may differ in the last digits, but the prefix and structure will be similar.

To find out the date, you can use online services to check IMEI. Type a 15-digit code in the appropriate field on specialized sites, and the system will give a report that often indicates Manufacturing Date. However, beware: free databases may not be updated, and for older models like Redmi 5 information may be missing or inaccurate.

A more complex but reliable method is to self-decrypt the serial number (SN). In Xiaomi devices, the serial number often contains a date code in the format of GGMM (year and month) at a particular line position. For example, if the SN has a sequence of 1712, this can indicate December 2017, the exact location of these numbers depends on the assembly plant (Foxconn, Wingtech, etc.).

To get the serial number, go to Settings → About Phone → All settings or dial *#06# and click on Serial Number. Write it down in full. Don't try to guess the date without an exact decoding table for a specific plant, as the structure of the SN can vary. It's better to use this number to request official support.

Using diagnostic applications

Modern utilities for Android allow you to access hidden parts of the system, which does not allow the standard interface. to determine the age of Redmi 5 are great applications like CPU-Z, AIDA64 or Device Info HW. These programs read data directly from the hardware registers of the processor and memory, making information almost invulnerable to software forgeries.

Once you install an application like CPU-Z, open the Device or System tab, and you'll find information about the time of first system boot or the kernel compilation date, which indirectly indicates the age of the device, and if the kernel is dated, say, November 2017, the phone was released no earlier than that.

But remember, the kernel compilation date isn't always the phone's build date. Devices could have been in storage for months before activation. However, the gap between software compilation and build is usually small. Apps will also show real screen resolution, number of cores, and the Snapdragon 450 processor model, which will help confirm the authenticity of the device.

⚠️ Note: Only download diagnostic snails from trusted sources, such as Google Play, to avoid installing malware that could steal your personal data.

Some specialized Xiaomi authentication apps may request access to the manufacturer’s servers to verify the serial number.This is the most accurate method, but it requires an active internet connection. If the app shows the status of “Warranty expired” and the activation date, this is the actual start of your smartphone’s life.

Comparative Characteristics Table of Redmi 5

To make sure you are looking at Redmi 5, not a modification or a fake, check your device’s parameters against the reference data. The model came in two main versions of memory, and knowing these nuances will help in identification.

If your phone’s settings have different options than the tabular ones (like 4GB of RAM or a Helio processor), you’re either on another model (like the Redmi 5 Plus) or a re-flashed copy. Redmi 5 has never been equipped with MediaTek processors in global versions.

Official request for Xiaomi support

If none of the above methods gave a clear answer, the most reliable, albeit longer, way is to contact official support Xiaomi. the company maintains a strict record of all released devices by serial numbers, you can write to the support chat on the official website or send an email.

To do this, you will need to provide a clear photo of the box with the sticker (if any) and a photo of the device itself, as well as specify the IMEI and serial number. Operators have access to an internal database that shows the exact date of production and the date of first activation (if the phone is connected to the Mi Account network).

This method is especially relevant if you are planning a lawsuit or return of goods, the response from support will be official, but consider the waiting time for a response, which can range from 24 hours to several business days depending on the workload.

In the request, be sure to specify the region of purchase of the device, as the databases can be divided by geographical area.The Chinese versions of Redmi 5 (CN) and global (Global) can have different prefixes in the serial numbers, which is important for correct identification.

💡

The combination of IMEI verification through online services and a visual inspection of a factory sticker gives 95% accuracy in determining the age of a smartphone without contacting the service.
