How to find out the release date of the phone Xiaomi Redmi Note 5A

The issue of determining the exact date of production of the device often arises for users planning to buy a used gadget or trying to assess the relevance of their device. Smartphone Xiaomi Redmi Note 5A (also known under the code name Ugglite or Ugg) is a popular budget model released several years ago, so checking its age becomes critical.

Electronics manufacturers rarely list a full calendar day on a box, limited to a month and a year, but there are proven methods for obtaining more detailed information. In this article, we will examine all the available methods, from simple visual inspection to using an engineering menu.

Understanding the age of the device will help you estimate the residual life of a lithium polymer battery, which degrades even in the absence of active use, and knowing the release date is necessary when searching for compatible parts or specific versions of firmware.

⚠️ Note: The activation date of the device in the Mi Account system may differ from the physical production date by several weeks or even months.

Analysis of factory labeling on packaging

The easiest and fastest way to get a firsthand look at the age of your Redmi Note 5A is to look closely at the original cardboard box. One side facet or end end usually has a white sticker with barcodes and basic technical information.

The format of the recording may vary depending on the region of delivery: it may be familiar DD/MM/YYYY more concise YYYY/MM. For example, a record "08/2017" Augustus 2017 It's important to understand that this is the final assembly date at the factory, not the date of sale.

If the box only shows the month and year, it means that the device was manufactured during that calendar period. The exact day in this format is not displayed, but for an overall assessment of the freshness of the battery, this is quite enough.

• 📦 Look for a white sticker with black text on the side of the box.
• 📅 Note the abbreviations "Mfg" (Manufacturing) or "Date of Mfg".
• 🌏 Please note that the date format can be Chinese (GYG-MM-DD) or European.

💡

Keep a photo of the sticker from the box in cloud storage – this will help when selling the device, as buyers often ask about the date of production.

Use of the Engineering Menu through USSD-code

To get more detailed technical information hidden from the average user, Xiaomi smartphones have a special engineering menu, accessed through a set of specific character combinations in the Phone app, which works even without an Internet connection.

Type ##4636## into the dialer. If the code is entered correctly, the system will automatically redirect you to the Testing menu. Here you need to select Phone Information. In the list that opens, look for lines that contain the words "Build date" or "Compile time."

This date indicates the time of compilation of the software that was installed in the factory. Usually, the firmware is installed on the device 1-3 days before packaging, so this date is a very accurate indicator of production time.

Checking Date Through System Files and ADB

More advanced users can access system logs and configuration files, which store the exact date of the build of the operating system, which requires a connection to the computer and the presence of Android Debug Bridge (ADB) tools installed.

Once you connect your smartphone to your PC in USB debugging mode, you can execute a command to output system properties. We're interested in the property ro.build.date.utc, which contains a time stamp in Unix format, or ro.build.date with a readable format.

adb shell getprop ro.build.date

The resulting date corresponds to the time of the firmware compilation. In the case of the Redmi Note 5A, which originally came out on Android 7.0 Nougat, this date will be close to the date of the model release in your region. If the phone was reflashed, this method will show the date of installation of the current firmware, not the iron production.

IMEI decoding and online services

Unique device identifier IMEI (International Mobile Equipment Identity contains encoded information about the manufacturer and model, but does not always include a direct release date in a readable form. IMEI, You can use third-party databases.

On mi.com or the Mi Store, you can sometimes check warranty status. By entering IMEI, you can see the date of first activation of the device or the warranty expiration date. By subtracting one year from the warranty expiration date (the standard term for Xiaomi), you can approximately calculate the purchase date.

There are specialized services, such as IMEI.info or PhoneCopy, that aggregate data from carriers and manufacturers, and they can show the expected month of release based on the IMEI range allocated to a particular batch of devices.

Redmi Note 5A Prime and Standard

It is important to consider that the line of Redmi Note 5A has two main modifications: standard (Standard) and improved (Prime/High Edition), which went on sale almost simultaneously in August-September 2017, but could have different dates of the beginning of mass production.

The Prime model was equipped with a fingerprint scanner and a large amount of RAM. If your device specifies a Snapdragon 435 processor and there is a scanner on the back, then this is the Prime version, which often comes in late 2017 or early 2018 for global markets.

The Chinese ROM always comes 2-3 months ahead of the global version, so if you buy a device that comes from China, the date on the box may be significantly earlier than the date of purchase in your region.

• 🆔 Model Model Standard (MDG1/MDG2) Often has earlier production dates.
• 🚀 Prime version (UGG) It was in great demand and produced longer editions.
• 🇨🇳 Chinese versions (China) ROM) They are marked with dates before global analogues.

⚠️ Note: When buying a used device, pay attention to the condition of the connectors. If the phone is 2 years old and the charging connector is very loose, it may be that the device was used very intensively.

Indirect signs of ageing of the device

Even without an exact release date, you can estimate the age of the Xiaomi Redmi Note 5A by indirect signs, especially the version of the operating system out of the box. If you see Android 7.0 or 8.1 on the first turn on without the possibility of rollback, the device is produced in the appropriate period.

Also worth paying attention to is the screen type: different Redmi Note 5A batches used arrays from different vendors (Tianma, EBBG, and others). While this doesn’t give an exact date, knowing the delivery period of screens by a particular vendor can help with expertise.

Physical wear is also eloquent: clouding of the plastic of the case, erasing the inscriptions near the charging connector and loss of battery capacity (less than 80% of the nominal value) are characteristic of devices older than 3-4 years of active use.

💡

Comprehensive check (box + engineering menu + appearance) gives the most reliable picture of the age of the device.
