Chronology of release and global release

The official presentation of the smartphone took place at the end of 2016, but it was a version for the domestic market of China. 2016 is considered the year of birth of the model in the line of Redmi. the Global version, adapted for Europe and CIS countries, reached the shelves much later.

The global launch of the device came in early 2017, when it was unveiled at MWC in Barcelona, which is the starting point for an international version with the necessary frequencies and languages, with a gap of about three months between the Chinese and global releases.

It is important to understand that the production date of a particular instance may differ from the announcement date.The back cover or box often has a build month.Devices released in late 2017 or even 2018 may have a slightly modified component base, despite the model being from the 2016-2017 generation.

Technical specifications and iron

At the heart of the device was Qualcomm's Snapdragon 435 processor, which was a great 28-nanometer eight-core chipset at the time of its release, and it provided a balance between performance and power consumption that was rare in the budget segment.

The screen of the smartphone had a diagonal of 5 inches and resolution HD (1280 by 720 points) Use IPS-It was standard for the (at the time) public sector, but today, this detail can cut the eye of those who are used to Full. HD+ user-user.

The case deserves special attention. Unlike many competitors who received glass or plastic backs, the Redmi 4X sported an all-metal body made of aviation aluminum, which gave the device a premium look and excellent heat transfer, although it degraded the cellular signal, for which plastic inserts were introduced.

Memory and configuration versions

Several modifications were released to the market, which differed significantly in the amount of RAM and internal memory, which is an important point when buying a used device, since the ability to install modern applications depends on this.

The base version offered 2GB of RAM and 16GB of internal storage, a more advanced version received 3GB of RAM and 32GB for files, and there was also a rare version with 4GB of RAM, but it was found mainly in the Chinese market.

Support for microSD cards allowed for storage to expand to 128 GB, which partially compensated for the lack of built-in capacity, but the speed of reading data from the card often limited the ability to install applications on an external medium.

Software and updates

At the time of release, the smartphone was running a MIUI shell based on Android 6.0 Marshmallow. Subsequently, the device received an update to Android 7.0 Nougat, which was the last major update of the operating system.

Support for security updates for this model was phased out a few years ago, meaning that system vulnerabilities found in recent years will not be fixed by the manufacturer.

⚠️ Note: Due to the lack of security updates, modern banking applications may not work or require complex system manipulations (root rights, Magisk) to run.

However, enthusiasts continue to port custom firmware to the device, which allows you to install more recent versions of Android, but the stability of the camera and communication modules in such cases is not guaranteed.

Relevance of the model in 2026

Almost a decade after its release, the Xiaomi Redmi 4X is becoming a rarity or device for specific tasks, and as a mainstream smartphone in 2026, it will only suit a very limited number of users with minimal requirements.

However, the device has a chance of a second life in the following scenarios:

• 📱 Digital photo frame or desktop clock.
• 🎵 MP3-podcaster.
• 🎮 Portable console for retro games (Dendy, Sega emulators, PS1).
• 📹 Video surveillance camera with Wi-Fi connection.

Buying this phone today is only justified as a temporary “bell ringer” or a device for a child to teach gadgets without the risk of smashing an expensive screen.

Battery problems and their solution

One of the main reasons for the model’s popularity was the 4100 mAh battery. Combined with an energy-efficient screen and processor, the smartphone lived easily for two days.

If you buy a used one, the probability that the battery has retained its original capacity is extremely small, and battery wear leads to rapid discharges and unexpected shutdowns in the cold.

Replacing the battery in this model is a moderately complex procedure. The back cover is not removed without heating, but access to the board and battery is opened after unscrewing a few screws. The original batteries are no longer manufactured, so the market reigns high-quality copies and outright marriage.

⚠️ Warning: When buying a new battery, avoid options with a declared capacity above the standard (for example, 5000 mAh in the case). 4X). Physically increase the capacity in the same dimensions is impossible, such markings are a fraud.
