Foldable Xiaomi: a revolution in pocket format

The mobile market is undergoing a period of transformation, and the foldable smartphone is no longer just a concept from futurists. Xiaomi, which has long watched the experiments of competitors, entered this arena with the Mix Fold line of devices, offering users a unique combination of flexible display and flagship stuffing. This device that folds, changes the very idea of multitasking and ergonomics in the hands of the user.

When you pick up a gadget like this, the first thing that catches your eye is the engineering marvel of the hinge mechanism. The 120Hz flexible AMOLED screen provides interface smoothness comparable to the best monoblocks, but when folded, the device becomes a compact device that is easy to carry in any pocket. It was UTG (Ultra-Thin Glass) technology that allowed engineers to create glass that can withstand hundreds of thousands of additions without losing transparency and tactile sensations.

But the choice between a conventional flagship and a foldable model often makes it difficult for buyers. Should you overpay for the ability to fold the screen in half? The answer lies in use cases: if you constantly work with documents, watch videos or play emulators, Xiaomi with a large internal screen will become an indispensable assistant. At the same time, for those who appreciate classic reliability and water resistance, traditional models may seem more familiar.

The evolution of the hinge: from the first Mix Fold to current versions

Xiaomi’s foldable phone story didn’t start with a perfect product, but with a bold experiment: the first Mix Fold had a noticeable crease in the middle of the screen and lacked full-blown water protection, which drew criticism from technology observers. But the company’s engineers quickly took into account the mistakes, introducing the second generation, where the hinge became significantly thinner, and the gap between the halves of the case in the folded state almost disappeared.

In the (third) and fourth generation of the device, the Chinese giant has been betting on collaborating with Leica and using titanium alloys, not only to reduce the overall weight of the structure, but also to increase its strength. The addition mechanism now withstands up to 200,000 bending cycles, as confirmed by TÜV Rheinland laboratory tests. It is important to note that each new iteration became lighteration and thinner than its predecessors, approaching the dimensions of conventional smartphones.

Modern models are equipped with advanced materials, such as carbon fiber, which is used in the inner structure of the frame, which allows you to distribute the load during bending and avoid deformation of the display in the area of the plume. If you are planning to buy, pay attention to the availability of the SPL (Swiss Precision Lubricant), which guarantees the use of a special lubricant in the hinge for silent and smooth operation of the mechanism even at low temperatures.

⚠️ Warning: Despite claims of strength, sudden movements when opening the device in the cold can damage the flexible plume.Let the smartphone warm up in your pocket before using it outdoors in winter.

Technical characteristics of displays and performance

The heart of any foldable Xiaomi is a processor. Current models use the top-end Snapdragon 8 Gen series chipset, which ensures the interface works without delay. The feature of optimizing the HyperOS system is adapting the interface to two form factors: an external narrow screen and an internal large panel. Applications are automatically rebuilt using a multi-window mode, which turns the smartphone into a pocketable tablet.

The image quality on the flexible LTPO AMOLED matrix deserves special attention. Support for HDR10+ and Dolby Vision makes viewing content incredibly bright and contrasting. The external screen usually has a standard aspect ratio of 21:9, which is convenient for typing with one hand. The internal display unfolds in a format close to square or 4:3, which is ideal for reading books, working with spreadsheets and surfing the web.

💡

Use Split Screen mode, running both the navigator and the messenger or YouTube and chat, which is the main thing that you buy foldable devices for.

In terms of autonomy, engineers have had to make trade-offs: the battery in foldable models is often composite or custom-shaped to fit in a thin case. However, quick charging with 67 watts or even 100 watts (depending on the model) allows you to replenish energy in 30-40 minutes. Optimizing power consumption in the background is critical here, as the large screen consumes a significant resource.

Camera and photo capabilities in the form factor "book"

One of the main problems of early warehouses was the camera, because of the thickness constraints, manufacturers put mediocre modules, but in the latest Mix Fold, the situation has changed dramatically thanks to the partnership with Leica. The large-sized main sensor, periscopic telephoto lens and ultra-wide-angle module now correspond to the level of the best camera phones in the market.

The unique thing about this is that you can use the external screen as a viewfinder, so you can fold the phone down, put it on the table, take a group photo, or you can move it from the main, better module, and you can control it through a small window, so you don't have to use a timer or ask people to take a picture of you.

The software includes Leica Authentic and Leica Vibrant filters. The former gives the photos a classic, slightly muted look with an emphasis on light and shadow, the latter makes the colors more saturated and bright. For video enthusiasts, image stabilization is available that compensates for the tremors of the hands, which is especially true when shooting with outstretched arms on the big screen.

⚠️ Warning: When shooting in folded phone mode, make sure the hinge is completely closed so that dust does not get on the external screen matrix if the design involves open camera modules.

Software and interface adaptation

The Android operating system in the HyperOS shell (formerly MIUI) for foldable devices has a deep adaptation. Developers have provided special widgets that occupy half the screen when folded, showing the weather, calendar or music management. When opened, these widgets can transform into full-fledged applications or move to the sidebar.

Drag and Drop works between open windows, so you can drag an image from the gallery directly into the text of a message or document, without the need for complex manipulations, just swipe your finger across the screen, and the system itself offers the optimal space division: 50/50, 70/30 or a floating window.

An important aspect is that it supports the stylus in some versions, and although it may not be available as a basic package, the digitizer allows you to take handwritten notes on a screen that is off or edit photos with high accuracy, making the smartphone a full-fledged working tool for designers and journalists.

Comparison with competitors: Samsung and Honor

When it comes to choosing, the Samsung Galaxy Z Fold and Honor Magic V come to mind immediately. Samsung offers longer-term update support and an ecosystem, but their devices are often thicker and have a noticeable fold. Honor relies on thinness and ergonomics, sometimes even ahead of Xiaomi in this parameter.

Xiaomi is in the “smart balance” niche in this race: They offer faster charging speeds than the Korean competitor and often more aggressive pricing policies in the domestic Chinese market, although global versions can cost a lot.

When looking at liquidity in the secondary market, Samsung is still leading the way, but Xiaomi’s stockpiles are growing in popularity, especially among tech enthusiasts, often boiling down to interface preferences: OneUI is more like one, and HyperOS philosophy is more like one.

Practicality and durability in everyday use

The main fear of folding smartphone buyers is fragility, the reality is that modern models are better protected than they seem, but the rules of operation still exist, and it is not recommended to drop the device down on the asphalt, since flexible glass is still more vulnerable to spot impacts than tempered glass monoblocks.

The IPX8 moisture protection in the new models makes it easy to avoid rain or accidental immersion in water, but dust protection (IP5X) has only come in the latest versions.

To extend the life of the device, it is recommended to periodically clean the flexion zone with a soft, dry cloth.The use of a protective case specially designed for a particular Mix Fold model is also necessary, since it takes on part of the impact load when falling.

⚠️ Warning: Never attempt to remove the factory protective film from the internal screen by yourself, which can cause the matrix to fail immediately, as the film is part of the display design.
