Xiaomi MIX Fold 2 Review: Enough For Everything

0

Xiaomi MIX Fold 2 uses the first-generation Qualcomm Snapdragon 8+ processor based on TSMC’s 4nm process technology. Under the same performance, the power consumption is 33% lower than that of Snapdragon 8, and there is 12GB LPDDR5 6400MHz + 1TB UFS 3.1 storage. combination. The camera is a 50-megapixel IMX766 main camera, a 13-megapixel 123° ultra-wide-angle, and an 8-megapixel telephoto Leica triple-camera combination.

These are just the basic elements that a flagship phone needs to have. Compared with the previous generation MIX Fold and other folding screen phones, Xiaomi MIX Fold 2 has made the following innovations and improvements!

Design

The thickness of the foldable mobile phones on the market is usually 16~18mm. The main reason is that the thickness of the mainstream water droplet shaft is 11.25mm, while the thickness of Xiaomi’s self-developed micro-droplet shape shaft is only 8.8mm. Combined with other technologies, the thickness is finally achieved. At 11.2mm, this is the thinnest folding screen phone at the moment.

On the left is the MIX Fold. The thick hinge causes a large gap in the screen when folded, while the MIX Fold 2 can completely fit the screen when it is folded. When folded, the thickness of MIX Fold 2 is only 11.2mm, which is the thinnest folding screen phone. When unfolded, the MIX Fold 2 is only 5.4mm thick, making it the thinnest smartphone ever!

Display

MIX Fold’s external screen resolution is 2520*840, a typical special-shaped screen, which is too narrow to be used as a normal mobile phone screen. Since the 8.01-inch internal screen has only a 60Hz refresh rate, it is obviously stuck in use, commonly known as a “jelly screen”.

First of all, the external screen uses a 6.56-inch Samsung E5 material AMOLED screen. The 21:9 screen ratio and 2520*1080 resolution are no different from normal mobile phone screens and can be used independently from the internal screen. The inner screen is the first mobile phone product in the industry to use the Samsung Eco2 OLED screen, 8.02-inch size, 4:3.55 ratio, 2160*1914 resolution, and its overall display area is comparable to the 8.3-inch iPad mini 6.

In addition, the two internal and external screens have been color-corrected before leaving the factory, with Delta-E≈0.34. In terms of parameters, they are all 120Hz refresh rate, 1000nit brightness, and support Dolby Vision and HDR10+. On the left is the remote control (MIX Fold), and the MIX Fold 2 on the right not only uses a standard-scale screen but also adopts a four-sided narrow frame design.

In addition, we have tested a variety of games, and they can display full screen when using the internal screen. The weight of the MIX Fold is 317g, and the weight of the MIX Fold 2 is 268g, which is nearly 50g lighter. The weight of 268g is about 20g heavier than a common 6.6″ mobile phone, but when looking at it as an 8″ mobile phone, this weight is actually very light.

The specifications of Xiaomi MIX Fold 2 are as follows:

Design & Appearance

In the folded mode, the size of the phone is 161.6 x 73.9 x 11.2mm, which is not much thicker than a normal gaming phone. The external screen uses a 6.56-inch Samsung E5 material AMOLED screen with a resolution of 2520*1080, a screen ratio of 21:9, a 120Hz refresh rate, 1000nit brightness, and also supports Dolby Vision, HDR10+, Delta-E≈0.34

In the unfolded mode, the measurements of the phone become 161.6 x 144 x 5.4mm, and it is difficult to find a thinner phone than it. The insider uses an 8.02-inch Samsung Eco2 OLED screen with a resolution of 2160*1914. Since the screen ratio is 4:3.55, the display area is the same as the iPad mini 6 with 8.3 memory.

Other parameters of the inner screen are almost the same as the outer screen, with a 120Hz refresh rate, 1000nit brightness, and also supports Dolby Vision, HDR10+, Delta-E≈0.34

Feel it, in the unfolded mode, it is much thinner than the 7.65mm iPhone 13 Pro. In the folded mode, it is not much thicker than the iPhone 13 Pro.

The MIX Fold 2 adopts a flat design, and the left and right heights are completely straight after unfolding, which is 5.4mm.

Verdict

The measurements of the mobile phone and the screen size of the tablet! I don’t know how many players’ dreams this is. From the release of the Galaxy Fold in 2019 to the present, the author has paid attention to every foldable phone on the market, hoping to find a miracle foldable phone in my mind. However, from hope to disappointment, it is almost numb now.

Before receiving MIX Fold 2, the author’s psychology did not fluctuate much. After all, the various gaffes of the MIX Fold are obvious to all. Even if the MIX Fold 2 is improved, it will definitely not be able to satisfy all the fantasies about the folding screen suddenly. Perhaps the truly practical folding screen needs to be iterated for another 5 generations, and the MIX Fold 7 in 2026 should be almost the same.

When the Xiaomi MIX Fold 2 was actually held in my hand, I was somewhat shocked. Even when it’s folded, it’s really a phone in your hand, not a thick and long remote. The 11.2mm folding thickness is the thinnest folding screen mobile phone at present, and the setting is not much thicker than the normal game phone.

Both the internal and external screens have a 120Hz refresh rate, and both have top-level screen quality, the same 1000nit ultra-high brightness, and the same color accuracy. There will be no situation where the external screen is just a decoration in the past, and the 60Hz internal screen operation feels like jelly.

That’s a bit too much to say, so let’s make a brief summary of this review.

1. Performance

Limited by the thickness of 5.4mm, the heat dissipation capacity of MIX Fold 2 is definitely not as good as that of top e-sports mobile phones like Xiaomi Mi 12S. However, in the limited space, the MIX Fold 2 has done its best to improve the heat dissipation performance and stuffed it into the 2520mm² liquid-cooled VC soaking plate.

The actual measurement found that the performance release of MIX Fold 2 is at a slightly above average level among all Snapdragon 8+ mobile phones. The highest image quality of “Genshin Impact” can stabilize at 60FPS, and games such as “Diablo: Immortal”, “Peace Elite”, and “Glory of the King” can also easily full frames.

2. Temperature

The temperature is a small surprise. We constantly run various games under high load, and the battery temperature of the mobile phone is between 37 degrees and 39 degrees most of the time.

After running “Yuan Shen” for 20 minutes, the highest temperature of the mobile phone case measured by the infrared thermometer was only 41 degrees.

3. Take pictures

The 50-megapixel IMX766 main camera, 13-megapixel 123° ultra-wide-angle, and 8-megapixel telephoto Leica triple-camera combination can meet normal photo needs without any problems.

Under the joint polishing with Leica, the camera of MIX Fold 2 also supports Leica Vivid, Leica Classic, All Things Focus, Movie Lens, Long Exposure Neon Luminous, etc. Students who are interested in taking pictures can develop more ways to play.

4. Battery life

When the MIX Fold 2 is folded, the measured battery life of the 6.56-inch screen is close to 11 hours. When using the 8-inch large screen in the unfolded state, the battery life is still nearly 8 hours.

For a folding screen phone, none of the above is the point, although the MIX Fold 2 has done a good job! Think about what the folding screen can bring.

When you play games or read comics, you can double the display area; you can display the map and status in the upper half of the game and the lower half like the 3DS; you can play games and open QQ and MSI chat boxes at the same time; The itinerary code and health code can be displayed on one screen at the same time……

Extremely thin and light, with top-level internal and external screens, and a variety of folding screen gameplay, MIX Fold 2 can be said to be the best folding screen mobile phone at present, and it is also the first folding mobile phone that can be used normally.

Of course, the significance of MIX Fold 2 is much more than that. Its birth has pointed out the direction for a number of domestic mobile phone manufacturers who are good at learning. I believe that it will not be long before we see more excellent and practical folding screen mobile phone products.
