Millet MIX Fold 4 release is about to usher in a full moon. As the fourth generation of Xiaomi Banner large folding screen mobile phone, the Xiaomi MIX Fold 4 can be described as a comprehensive upgrade in weight (226g), thickness (4.59mm thickness after expansion, 9.47mm thickness after closing) and appearance design and image experience of these key values, once again from the inside out, a new look.

After nearly a month of use, today, the digital Lab will talk about the intuitive use of this Xiaomi top large folding mobile phone from the two aspects of grip feel and image experience.

When it comes to the grip of the phone, it is closely related to the design of the phone. This one in my hand is the Gentian blue color of Xiaomi MIX Fold 4, which sets the overall business steady style. The back cover of "Gentian Blue" is made of ultra-thin glass fiber process, not traditional glass, which is the reason why it can be thinner and higher strength, and also an important factor in the feel to ensure that it can be held for a long time without leaving sweat stains and fingerprints.

The focus is on the control of the frame and thickness of the millet MIX Fold 4. Thanks to the metal frame and four micro-curved body design, the thickness of the whole machine comes to 9.47mm after closure. After three generations of polishing and market exploration, such a feel is also one of the folding screen mobile phones that are closest to the straight screen experience on the market at present, and even achieve "far beyond" relative to the right Angle frame straight screen machine.

In terms of weight, in order to achieve the installation of a submerged camera and achieve weight reduction, the Millet MIX Fold 4 uses a "full carbon architecture", from the axle float plate to the screen liner board, and then to the battery compartment liner board in the middle frame all use 100% carbon fiber materials, directly reducing the weight of the phone to 226g, which is currently in the first tier of the industry. As for the hinge, millet keel axle 2.0 compared with the previous generation, the overall volume is reduced by 34%, the weight is reduced by 16%, and the axle folding life is more than 500,000 times.

Just from the opening and closing experience, the Xiaomi MIX Fold 4 hinge is somewhat tight in the closed state, and it needs to be opened with a little force. The reason for this is precisely that the frame of the mobile phone is designed to be very thin, but it is naturally good to close some, such as fine particles will not enter the inner screen, and when using the outer screen, the mobile phone feels better, so it is not a big problem.

In other aspects, the external screen part of the Xiaomi MIX Fold 4 also uses a four-micro curved screen design, which also brings a very excellent external screen look and feel. Excluding various factors such as "religious belief", this time millet in the MIX Fold 4 process design, indeed made enough efforts, since I got it, there is no sufficient reason to let me change the machine.

In addition, the Mi MIX Fold 4 is equipped with 7.98-inch inner screen + 6.56-inch outer screen, two screens with top quality in all aspects of parameters, and covered with Mi Dragon crystal glass (outer screen) and UTG protection glass (inner screen). At the same time, the Mi MIX Fold 4 also makes IPX8 waterproof, which is also the first folding screen that supports IPX8 waterproof.

Next to say or mobile phone image, this time the Xiaomi MIX Fold 4 camera module appearance is still changed, the shape has become a "shield" shape, on the lens module, attach a fine mesh texture, silver Leica logo printed on the side of the four cameras, Together with the "shield" lens module, it forms the important product recognition of Xiaomi MIX Fold 4.

In terms of configuration, the millet MIX Fold 4 rear Leica Optical Summilux four camera is still the only "four camera five focal segment" with the current folding screen, respectively using 50 million pixel light hunter 800 main camera (1/1.55", 1G+6P, F1.7, F1.7). OIS) + 12MP ultra wide Angle (OV13B10, 120°)+ 50MP portrait vertical telephoto (Howe OV60A40, floating focus)+ 10MP latent telephoto (Samsung S5K3K1, OIS). The front of the outer screen is 16MP(Howwe OV16F40), and the front of the inner screen is 16MP(Howwe OV16F40).

Although the "good look" of the photo, everyone's aesthetic is different, but in the entire folding screen product category, as well as the mobile phone market, the sample taken by Xiaomi still has a distinct style. We take four focal segments of 0.6 times ultra-wide Angle (15mm), 1 times main lens (23mm), 2 times telephoto (47mm), 4 times telephoto (94mm), and 5 times periscope (115mm) as examples to see the performance of the sample.

The following is a proof shot

0.6x ultra wide Angle (15mm)

Double main camera (23mm)

2x telephoto (47mm)

4x telephoto (94mm)

5x periscope (115mm)

50mm, 35mm portrait modes

From the proof, the Mi MIX Fold 4 film quality is very good, of course, compared with the current high-end plate flagship, due to the limited fuselage architecture space, can not place a larger image sensor and other factors, shooting extremely complex scenes (such as night ultra-dark light, long distance telephoto) there is a certain gap, but the overall photo quality has been the industry's first-class level.

In the photo style, the "Leica flavor" seems to be a natural fit with the Xiaomi style, or now you can directly equate Leica and Xiaomi in the field of mobile imaging. Whether you open "Leica Classic" or "Leica Vivid", the light and shadow presented by the scene come to life.

Specifically, thanks to the 50 megapixel 2x floating lens, the focus gap between the main camera and the periscope is directly filled, and the main lens zoom is not required in this focus segment. The 47mm focal length brought by the 2x lens is quite suitable for portrait shooting, and another important thing is that this independent 2x lens extends the focal length to 4 times and can be perfectly connected with the 115mm stealth lens.

Overall, the Xiaomi MIX Fold 4 showed an impressive performance in a strong light scene. In terms of tolerance, the generation ability of 14bit HDR photos makes it possible to retain and present both highlights and shadows well. In addition, under high zoom, the picture clarity and sharpness of the Xiaomi MIX Fold 4 are equally impressive.

The above is the overall evaluation given by the digital Lab after using the Xiaomi MIX Fold 4 for a period of time, based on the appearance design, grip feel and image experience. As Xiaomi's fourth generation of large folding products, from the perspective of the current mobile phone market, Xiaomi MIX Fold 4 in reducing, thin at the same time, but also to ensure the all-around experience: performance is undoubtedly, Snapdragon 8 Gen3 performance iron triangle; The first Jinsha Jiang battery integrates the large capacity of 5100mAh with thin and light, thus further improving the battery life experience of the mobile phone.

If it is further from the enterprise strategy level, when the technology is mature and stable enough, after three generations of market exploration, through the full use of the advantages of micro four-curve screen, the careful study of the mobile phone architecture and the pursuit of the ultimate thin and light feel, the millet MIX Fold 4 has become a very outstanding product in the current market category of large folding mobile phones. Undoubtedly, it is a major breakthrough for Xiaomi in the field of folding screen mobile phones. At the same time, based on Xiaomi's own continuous accumulation of self-developed technologies, and let these technologies one by one in the millet MIX Fold 4 has been practical application, but also a strong proof of Xiaomi's foothold in the high-end market.
