Xiaomi Mi Mix 2: What year is the model and is it worth buying?

In a mobile world where new products are introduced every few months, some devices are becoming legends, setting trends for years to come. This is the category that includes the Xiaomi Mi Mix 2, a smartphone that many experts still call revolutionary. The question of what year the Xiaomi Mi Mix 2 is released, often arises for those who are looking for a balance between high performance and affordable prices in the secondary market.

The device is a continuation of the Chinese giant’s bold experimental lineup, offering users a nearly bezelless screen long before it became the industry standard: the device was officially unveiled on September 11, 2017, bringing it to the same level as the flagships of the period, such as the iPhone X and Samsung Galaxy Note 8. Understanding the release year is critical to assessing the relevance of its hardware and software support.

In this article, we will analyze the model’s release timeline, analyze its key features that are relevant even after years, and answer the most frequent questions of potential buyers. You will learn why this gadget is still of interest to collectors and enthusiasts, and whether it is worth considering buying it as a primary or a backup device.

History of creation and date of entry into the market

The concept smartphone was developed in secrecy and came as a shock to the tech community, and after the success of the first Mi Mix, the company’s engineers set out to make it more ergonomic and accessible to the general public while maintaining a futuristic design.

The presentation was held simultaneously in Beijing and at a global event in India, which underscored the strategic importance of the model for the brand’s entry into international markets, and unlike its predecessor, which was more of an experimental prototype, the second version received full certification and widespread distribution.

The launch in China began just days after the announcement, in late September 2017, and the global version reached the shelves of Europe and Asia a little later, in October and November of that year, and for its time, it was an incredibly fast launch cycle, demonstrating the readiness of the production chains to mass-produce complex devices.

Importantly, in early 2018, a special version of the Xiaomi Mi Mix 2S was introduced, which featured a more powerful processor and an improved camera. However, the classic Mi Mix 2 remained in history as a model of 2017, cementing the company’s status as a manufacturer of premium devices.

Technical characteristics and key features

At the time of its release, the smartphone had the top-end features that allowed it to compete with the best flagships of the time, the heart of the device was the Qualcomm Snapdragon 835 processor, made on a 10-nanometer process, which ensured high energy efficiency and excellent performance in heavy games.

One of the big things was the 18:9 aspect ratio, which was new to the industry, and it had a 5.99 inch display, but it had a thin frame that was comparable to a typical 5.5-inch smartphone, which was a completely immersive experience when viewing content.

• 📱 Screen: IPS LCD, permit 2160x1080 pixels, Corning Gorilla Glass 4 protection.
• ⚙️ Memory: Operational memory 6 GB, built-in 64/128/256 GB without support for microSD cards.
• 🔋 Battery: 3400mAh with Quick Charge 3.0 support.
• 📷 Camera: Basic module 12 MP (Sony) IMX386) dual-phase autofocus.

The frame is made of 7000 series aluminium aircraft alloy, and the back cover is made of ceramics, which not only gave the device a premium look, but also provided excellent heat sink, which is critical for a powerful processor.

Design and ergonomics of frameless housing

The visual style of the device became his hallmark, and engineers managed to minimize the top and side bezels, leaving only a small strip at the bottom to accommodate the electronics and logo, a solution that achieved a screen area utilization rate of 81.5%.

The ceramic back panel is not only beautiful, it's also nice to touch, it doesn't scratch as easily as glass, and it doesn't collect fingerprints to the same extent, but it's worth remembering that ceramics are fragile, and if you fall on a hard surface, the risk of splitting is quite high.

⚠️ Attention: Due to the lack of a top frame, the speaker (conversational) is made in the form of a piezoelectric system vibrating with the screen. The sound quality depends on the density of the ear adjacent to the top of the screen.

The ergonomics of the device also changed from the first Mi Mix. The smartphone is narrower and more comfortable in the hand. Weight 185 grams feels quite comfortable, despite the metal frame. The location of the camera module and fingerprint scanner on the back was thought out for easy access with the thumb.

💡

When buying a used Xiaomi Mi Mix 2, be sure to check the integrity of the ceramic cover around the camera - this is the most vulnerable place when falling.

Software and relevance of the OS

At the time of launch, the smartphone was running the Android 7.1 Nougat operating system with a proprietary shell MIUI. Subsequently, the device received updates to Android 9.0 Pie, which was the last major update to the OS version from the manufacturer.

Despite the end of official support, the model remains popular in the development community, thanks to the unlocked bootloader, you can install custom firmware on the device, including the latest versions of Android 11, 12 and even 13, which allows you to extend the life of the gadget for several years.

However, users should consider that newer versions of Android may run less stable on older hardware or consume more battery life.The official shell of MIUI, even in the latest available versions, remains quite optimized for this processor.

Comparison with 2017 competitors

To understand the Mi Mix 2's place in history, you need to compare it with contemporaries. The main competitor was considered the Samsung Galaxy Note 8, which offered the best AMOLED screen and stylus, but cost much more. Apple iPhone X, released almost simultaneously, set the new Face ID standard, but had a controversial bang.

Unlike its competitors, Xiaomi offered a near-complete screen with no cutouts, a unique selling proposition at the time: the fingerprint scanner on the back worked quickly and reliably, while the iPhone X’s biometrics were only switching to facial recognition.

In terms of performance in games, the smartphone performed at the level of the leaders of the AnTuTu ratings of the time, cooling copes with loads better than many glass competitors, thanks to the ceramic body and competent heat distribution inside.

Should you buy Xiaomi Mi Mix 2 in 2026?

Buying a 2017 smartphone in 2026 is a decision that requires a measured approach, and on the one hand, you get a high-quality screen, premium materials and a design that still looks more modern than many public sector employees.

On the other hand, the battery could degrade over the years, and the lack of security updates makes the device vulnerable, and spare parts like screens or back covers are becoming rare and expensive.

• ✅ Pros: Unique design, high-quality sound, 3.5 mm connector, IR port, good performance for basic tasks.
• ❌ Cons: No Android updates, battery wear, fragile ceramics, no waterproofing IP68.

It's a great device for collectibles, a baby device, a second phone for calls, or a media player, and may be a little weak for use as a primary device in 2026 due to the demands of modern applications.

⚠️ Note: When buying a used device, pay attention to the presence of a Mi Account. If the previous owner did not untie the device, you will not be able to fully use the smartphone.
