Xiaomi Mi 12: release date, specifications and is it worth waiting?

The question of when exactly the Xiaomi Mi 12 flagship smartphone was released is still relevant for those looking for the optimal value for money in the used or residual device market. The initial presentation took place in China in late December 2021, making it one of the first devices to receive the then-new Snapdragon 8 Gen 1 processor. The global version, adapted for the European and Russian markets, reached the shelves a few months later, in early 2022, which created some confusion in the dates of potential buyers.

Many users are still wondering whether to consider this model for purchase in the current realities or better pay attention to the newer generations. The official date of global release is March 15, 2022, this day is considered the starting point for the appearance of the device in international retail. Understanding the release chronology helps not only to estimate the age of the gadget, but also to predict the timing of the end of support for software, which is critical for data security.

In this article, we will take a closer look at the history of the device, the key features of its hardware platform and answer the most frequent questions related to the operation and relevance of the model. If you are looking for a compact flagship with powerful hardware, the analysis of the technical characteristics of the Mi 12 will be especially useful for you, as this series has become a landmark for the company.

Chronology of the exit and regional features

The Xiaomi Mi 12 story is unique in that it made a strategic decision to launch the device in China before the traditional MWC cycle in Barcelona, which was presented in China on December 28, 2021, allowing Xiaomi to capture the holiday sales market.

The gap between the Chinese and global releases was two months, standard practice for calibrating software to Google’s international communications standards and services. In Russia and the CIS, sales started in March 2022, but due to the logistical difficulties of that period, real deliveries to retailers began later, creating a situation where the device was formally long gone and physically available only by mid-spring.

⚠️ Warning: When buying a device released in late 2021, be sure to check the warranty activation date. Often sellers can pass off devices that have been in stock for more than a year as a "new" product, which reduces the battery life.

Importantly, in some regions, the model was sold under different names or memory configurations, and regional features also included support for 5G frequencies, which in the Chinese version were more advanced than the European version, which is worth considering if you plan to use a smartphone on trips or buy a version imported on parallel imports.

Technical specifications and hardware platform

The heart of the smartphone was the 4-nanometer Snapdragon 8 Gen 1, which was the absolute top of the market at the time of its release, providing the highest performance in games and heavy applications. However, as practice showed, the chipset had a tendency to heat, which required Xiaomi engineers to develop a complex cooling system using a graphene layer and a large evaporator.

The screen of the device deserves special attention: it is an AMOLED-matrix diagonal of 6.28 inches with a resolution of 2400×1080 pixels. Unlike the older Pro version, it uses flat glass, which greatly simplifies the sticking of protective glasses and the use of cases. The refresh rate is 120 Hz, and peak brightness reaches 1100 nits, which provides excellent readability even in direct sunlight.

• 📱 Display: 6.28" AMOLED, 120Hz, Gorilla Glass Victus.
• ⚙️ Processor: Qualcomm Snapdragon 8 Gen 1 (4 nm).
• 🔋 Battery: 4500mAh with quick charging of 67W.
• 📸 Camera: 50 MP Basic Module (Sony) IMX766) optically stabilized.

The amount of RAM, depending on the version, is 8 or 12 GB of the LPDDR5 standard, and the built-in storage is based on fast UFS 3.1 memory. This bundle provides instant application launch and high speed video recording. For users who store large amounts of data, it is important to consider the lack of a memory card slot, so choosing a version with a large amount of internal storage (256 GB) may be preferable.

Comparison with competitors and positioning

At the time of its release, the Xiaomi Mi 12 was positioned as a direct competitor to the Samsung Galaxy S22 and iPhone 13. The main trump card of the Chinese manufacturer was the price: the flagship cost much cheaper than its counterparts from Samsung and Apple, while offering similar or even superior performance in synthetic tests, which made the model a hit sales among those who do not want to overpay for the brand.

But in terms of photo and video stabilization, competitors from Cupertino and Suwon still held the palm. Xiaomi’s photo processing algorithms are good, but sometimes they are sinning with excessive sharping or unnatural sky color. However, the presence of optical stabilization (OIS) in all camera modules has reduced the gap in nighttime quality.

Xiaomi's big advantage was the package: the box immediately gave the customer a powerful power supply and protective case, while competitors actively refused to chargers, forcing users to buy them separately, increasing the total cost of ownership, this marketing move significantly influenced the perception of the value of the product.

💡

When comparing prices in the used market, consider the cost of replacing the battery. For the Xiaomi Mi 12, the original battery costs less than for the iPhone, making it more economical in the long run.

Software and updates

The smartphone was originally released on the basis of the Android 12 operating system with the shell MIUI 13. Since then, the device has received several major updates, including the transition to MIUI 14 and the current HyperOS. The company’s policy involves supporting flagship models for 3-4 years with major Android updates, which guarantees the relevance of functions until 2026-2026.

The update process is done via the Settings menu → About Phone → MIUI version. Users can choose between automatic downloading or manual update search. The firmware’s stability improved with each release: if early versions suffered from periodic micro-freezes of the interface, the updates optimized the system’s performance.

• 🚀 HyperOS: New shell reduced the consumption of RAM.
• 🛡️ Google Security patches are released quarterly.
• 🎨 Interface: Improved animation and widgets.

It’s worth noting that global firmware versions come with a delay relative to Chinese ones, due to the need for Google certification and regional adaptation. For advanced users, there is the option of installing Chinese firmware and then installing Google services, but this requires unlocking the bootloader, which may not be safe for inexperienced users.

⚠️ Note: Unlocking the bootloader is officially possible only 7 days (168 hours) after the Mi Account is attached.

Typical problems and operational issues

Despite being a flagship, the model has a number of features to be aware of. The main problem with the Snapdragon 8 Gen 1 platform is heating. In heavy games or when recording video in 4K, the body can heat up to 40-42 degrees, which causes trolling (decreased performance) to protect the components. This is not a defect, but a feature of the chip architecture.

The second thing is the communication module, and in the early global versions, there were complaints about the unstable operation of Wi-Fi 6 and switching between 4G towers. With the release of firmware updates, most of these problems were fixed, but when you buy a device from hand, you should check the version of the software. If there is an old version on board, it needs to be updated.

Users also note that the fingerprint scanner built into the screen works quickly, but can be mistaken with poor quality protective glass. Optical camera stabilization sometimes makes a quiet rattling sound when shaking the phone - this is normal for mechanical OIS modules and is not a sign of failure.

💡

The main risk when buying the Mi 12 is the battery condition, as the model came out a long time ago, and many copies have already passed the full charge-discharge cycle of hundreds of times.

Should you buy Xiaomi Mi 12 in 2026?

In 2026, the Xiaomi Mi 12 moves into the mid-range budget device category for performance, but retains the flagship body materials and screen. Buying it makes sense if your budget is limited, but you want a quality build, a good screen and support for fast charging. For everyday tasks (social networks, navigation, YouTube), its power is still more than enough.

However, if you are a mobile gamer or professional video shooter, it is better to consider newer models that solve overheating problems and improve photo processing algorithms. The market for used technology offers these devices at very attractive prices, often in a “new” state, which makes them an excellent choice as a first smartphone for a child or a spare device.

The deciding factor is price, because if the device costs less than 30-40% of the price of current products, it is a bargain, otherwise, with a little budget, you can find the previous generation of devices with a warranty and a fresher hardware.
