Xiaomi Mi 12: release date, specifications and relevance in 2026

The question of when exactly the legendary Xiaomi Mi 12 appeared on the market is still of great interest to fans of compact flagships, especially given that in 2026 it is becoming increasingly difficult to find a quality small smartphone.The official premiere of the device took place in China on December 28, 2021, which made it one of the first gadgets to receive the latest at the time chipset Snapdragon 8 Gen 1. The global version was presented a little later, in February 2022, during the MWC event in Barcelona, where the brand confirmed its ambition to capture the premium segment.

Many users confuse the announcement and the actual start of sales, as between the presentation and the appearance of the product on the shelves of stores could be several weeks, December 2021 is considered the starting point for this line, which set the new standard of ergonomics with a diagonal of 6.28 inches. Today, looking back, it is safe to say that this was a turning point for the company decided to experiment with the form factor in the era of giant shovels.

Release history and global expansion

The Chinese market traditionally receives Xiaomi’s new products before the rest, and the Mi 12 was no exception: the start of pre-orders in China began immediately after the presentation, and the first customers received their devices in the first days of 2022. For the international community, including Russia and CIS countries, the device became available in the spring, which is standard practice for certification of global versions of software and adapting communication frequencies.

It is important to understand the difference between the base model and the Pro or X versions, which came out with a small time lag. The base model was positioned as a “people’s flagship” with a focus on compactness, while the Pro version targeted photographers and demanding users. The global expansion was successful, although it faced some logistical difficulties characteristic of the period.

It is worth noting that in some regions, shipments could be delayed, creating artificial excitement and speculation in the market, the real availability of the device in retail networks in most countries in Europe and Asia improved by March-April 2022, which allowed the device to compete with the Samsung Galaxy S22 and iPhone 13, which were also relevant at the time.

Technical characteristics and key features

At the heart of the device was the 4nm Snapdragon 8 Gen 1, a chip that provided tremendous performance for its time, but had a tendency to heat under load, which was the subject of much discussion on forums. The 120Hz AMOLED E5 screen offered incredible interface smoothness and brightness of up to 1,100 nits, making the picture readable even under direct sun.

The camera was another pride of Xiaomi engineers. The 50MP core module with Sony IMX766 sensor and optical stabilization allowed for detailed images even in low light conditions. The wide-angle lens and telemacro camera complemented the main set, giving the user a wide creative range.

• 📱 Screen: 6.28 inches, AMOLED, 120Hz, resolution. 2400x1080 pixel.
• ⚡ Processor: Qualcomm Snapdragon 8 Gen 1 (4 nm), 8 cores.
• 🔋 Battery: 4500 mAh with support for fast charging of 67W and wireless 50W.
• 📸 Camera: Triple system (50 MP) + 13 MP + 5 MP), front 32 MP.

Special attention should be paid to the cooling system, which was significantly redesigned compared to previous generations. The use of graphene film and a large evaporation area allowed to more effectively remove heat from the SoC. However, as practice has shown, in hot climates or in heavy games, the case could still be significantly heated, which is a physical feature of compact housings.

Comparison of Xiaomi Mi 12 and Mi 12 Pro

Choosing between the regular and Pro versions often leaves buyers baffled, as the price difference at the start was significant, but the differences in functionality are not always obvious to the average user. Mi 12 Pro received a larger 6.73-inch screen with WQHD+ resolution and a third telephoto lens with 2x optical zoom. The base model, in turn, benefited from the compactness and ease of use with one hand.

The Mi 12 Pro had a 4600mAh battery in terms of autonomy, but because of its more energy-intensive screen and high resolution, the operating time could be comparable to the base model. For users who care about zoom quality and maximum screen detail, it was worth overpaying for the Pro version. For others, the Mi 12 remained a more rational choice.

💡

When buying a used device, be sure to check the battery status in the engineering menu, since intensive charging could quickly wear the battery over the years of use.

Both devices were designed in the same style, but the Mi 12 Pro looked more massive and heavier. The camera block on the back also had different layouts. If you prioritize ergonomics and the ability to comfortably work in crowded vehicles or keep your phone in your pocket, the standard version wins unconditionally.

Software and Relevance of Updates

At the time of release, the smartphone was running the MIUI 13 shell based on Android 12. Since then, the device has received several major updates to the operating system, including the transition to MIUI 14 and subsequent versions, which confirms the long-term support from the manufacturer. In 2026, the relevance of the software is a critical factor when buying a device of previous generations.

The device can now claim to receive updates to HyperOS, Xiaomi’s new ecosystem, which means that users not only get security patches, but also new features, widgets and improved animations. Support for new versions of the software by old flagships is a rare phenomenon in the Android world that is highly valued by the community.

However, it is worth considering that with each year of updates, older devices may be slower due to increased software requirements to the hardware. If you plan to use the phone for a few more years, make sure that the current version of the firmware is stable and does not cause problems with autonomy.
