Introducing Mi Mix Fold, the first Xiaomi folding phone and the world’s first liquid lens

News unit EMGblog.com: Mega launch event Xiaomi which yesterday unveiled Mi 11i, Mi 11 Pro, Mi 11 Ultra and Mi 11 Lite (in two 4G and 5G version) started, on March 30, 2021 (April 10, 1400), it continued with another different phone in the Mi Mix family, which has a big difference with all the previous members of this series; Mi Mix Fold According to its name, it is the first folding phone of Xiaomi company, which in terms of appearance should be similar to examples such as Galaxy Z Fold2 from Samsung and Mate X2 from Huawei knew. The main screen of this phone is bent inward and another screen can be seen outside. Mix Fold is of course (when closed) thicker than both other competitors and weighs more.

Mi Mix series Xiaomi has been a place to display innovative ideas of this company in the last 5 years, and each model has new attractions, especially in the field of screen; Among these innovations can be Mi Mix The first and its successor is pointed out that today’s full-screen displays look somewhat borrowed from them. Mi Mix 3, moved the selfie camera to the back part in the form of a slide, and the concept phone Mi Mix Alpha also used the screen around the phone. Mi Mix Fold But unlike other innovative members of this series, it doesn’t look very different, and despite some new points in design and implementation, and at the top of them is the idea of ​​the liquid lens of the telephoto camera, it can be considered a similar product and close to other usual folding phones.

Design and appearance

In the first step, getting to know Mi Mix Fold should be mentioned about its U-shaped hinge, which, according to the manufacturer, has led to a 27% reduction in weight compared to other competitors. Of course, what Xiaomi means by this weight reduction apparently belongs to the hinge itself, because the total weight of the device (317 grams in the normal version and 332 grams in the special ceramic version) compared to both the Mate X2 with a weight of 295 grams and the Galaxy Z Fold2 5G with a weight of 282 Warmth seems much heavier. According to the manufacturer, Mix Fold has been opened and closed up to 200,000 times in reliability testing and up to 1 million times in extreme reliability testing, and the accuracy of its performance has been confirmed in both of these modes. .

Dimensions and weight

Mix Fold has a length of 173.27 mm, which is a big difference compared to Mate X2 with a length of 161.8 mm; Above all, this difference should be attributed to the different image ratio of the external screens of these two models, and to be sure, go to their width; The width of Mix Fold in both closed and open modes is 69.8 and 133.38 mm, respectively, which as expected are much less than the width of Mate X2 in these two modes, i.e. 74.6 and 145.8 mm. In other words, Mix Fold in closed mode compared to both models. Huawei Mate X2″>Mate X2 and Galaxy Z Fold2 is a longer and narrower device, and although it does not seem easy to access all parts of its external screen with one hand, but with a smaller width, it can fit better in the hand. take As mentioned, the weight of the device is 317 and 332 grams, respectively, in the normal and ceramic version, which is much more than usual for a mobile phone.

In terms of design and body material, this phone is produced in two standard and ceramic versions, and the back part in the standard version is made of glass Gorilla Glass 5 with ceramic designs, but in the version Ceramic is completely used of this material and the central frame and volume buttons are designed in gold color.

External screen

The external screen of the device, which according to

Internal screen

Attractiveness Mix Fold Naturally, it starts with opening the device and displaying its main screen; This phone uses an 8.01-inch OLED screen with a ratio of 4:3, which Xiaomi refers to it as the biggest folding screen currently on the market. The resolution of this screen is 1860 x 2480 pixels, which results in a density equal to 387 pixels per inch. The brightness of this panel is announced as 600 nits and it uses a contrast of 4,300:000:1. DCI-P3 color gamut and Dolby Vision support are other announced features of this screen. The Mix Fold’s internal screen is a 60Hz sample with a 120Hz touch sampling rate, both of which are lower than the Mate X2’s 90Hz panel and 180Hz touch sampling rate.

A separate desktop mode has also been defined for this screen, which looks like a tablet, and to activate it, you can move three fingers on the panel at the same time.

main cameras

another The attractions of the Mix Fold belong to the image section and its camera set, which offers a double attraction with the presence of the new image signal processor (ISP) made by Xiaomi, the Surge C1. Of course, making a processor in Xiaomi’s collection is not new, and this company already in the beginning of 2017 used the chip Surge S1 had been unveiled. The Surge C1 chip, which Xiaomi considers to be the result of two years of continuous research and spending 140 million yuan in the research and development department, supports the implementation of three algorithms: autofocus, automatic exposure and automatic watt balance with more efficient energy consumption.

New ISP And independently, of course, Mix Fold is not the only attraction in this section, and more importantly is the Liquid Lens technology used in the device’s telephoto camera; The lens of this camera is a flexible layer that is filled with a clear liquid and its shape and state can be changed thanks to an adjusting motor just like the human eye. Mix Fold’s 8-megapixel telephoto camera supports 3x optical zoom and 10x digital zoom, and thanks to liquid lens technology, it will be able to shoot from a very close distance of 3 cm. The mechanism of this set is resistant to temperature changes and offers the possibility of working in a wide temperature range from minus 40 degrees to plus 60 degrees.

The main 108 megapixel camera of the device from 1/1.52 inch sensor Samsung HM2 which After combining 9 adjacent cells, its pixels reach a large size of 2.1 microns at a default resolution of 12 megapixels. This camera apparently does not have OIS or optical image stabilization, which, considering the very high price range of the device, is an obvious negative for Xiaomi. The front lens of this sensor is 7-stage and its aperture is f/1.75. The maximum recording resolution of the main camera of this model is 8K/30fps and it also supports 4K and 1080p resolution with 30 and 60 frames per second.

Apart from these two cameras, Mix Fold uses another 13-megapixel ultrawide unit that creates a wide image with a 123-degree angle. This camera apparently lacks automatic focus and its aperture is f/2.4.

Processor – Memory

Device processor as expected 5nm processor Snapdragon 888 is from a core Cortex X1 with a frequency of 2.84 GHz It uses 3 2.42 GHz cores at the highest level and in the other two clusters respectively. Arm Cortex-A78 and 4 1.8 GHz cores A55 are considered. Adreno 660 is responsible for graphics processing in this chipset. The LPDDR5 RAM of the device is 12 or 16 GB and it has 256 or 512 GB of UFS 3.1 internal memory.

The cooling mechanism of this model is another interesting thing that should be mentioned. This mechanism, which the manufacturer calls butterfly-type, occupies a large area of ​​22,583 square millimeters and combines a large steam chamber. Thermal gel and multiple layers of graphite sheets remove heat not only from the device’s processing chipset, but also from the 5G antennas and the phone’s fast charging system.

Quadruple Speakers

Another attraction of Mix Fold, for which almost no other example can be found in mobile phones, is the presence of 4 speakers in the structure of this model, two on the left and two on the right. The screen (open in landscape mode) is placed and like other new Xiaomi Mi 11 series flagships, it is tuned by Harman/Kardon group. The 1216 line speakers of this model are powered by powerful 15V amplifiers, which according to Xiaomi produce up to 40% more sound than Mi 10 Pro. Another interesting thing to note about the four speakers of this model is their spatial sound algorithm, which creates an immersive audio experience.

Battery – communication options

The battery capacity of the device is 5,020mAh, which compared to the 4,500 mAh battery present in both Mate X2 and Z Fold2 models, has more capacity and also reduces the weight of the device. It should be attributed to this battery. This battery is powered by a 67W fast charger that will be able to fully charge it in just 37 minutes. Wireless charging is apparently not supported in this phone.

Mix Fold supports Wi-Fi 6, Bluetooth 5.2 and NFC in the communication section, apart from 5G, and dual-frequency routers are also seen in it.

Price – time in the market

Xiaomi Mi Mix Fold with operating system Android 10 and the MIUI 12 user interface are available for pre-order in the Chinese market from today, and its presence in This market has also been postponed to April 16 (April 27, 1400). The standard version of this model with a base memory of 12GB/256GB has a price of 9,999 yuan (at the current exchange rate of nearly 1,521 US dollars), and for the 12GB/512GB version, you have to pay 10,999 yuan (1,674 dollars). Finally, the ceramic visa version of this model is also offered to the market with 16GB/512GB memory at a price of 12,999 yuan ($1,978). As an example, it is not bad to compare the prices of Huawei Mate X2 Let’s remember that in two versions of 256 GB and 512 GB (both with only 8 GB of RAM), they are priced at 18 and 19 thousand yuan, respectively.
