    The Xiaomi Mega launch event, which started yesterday with the unveiling of the Mi 11i, Mi 11 Pro, Mi 11 Ultra and Mi 11 Lite (in both 4G and 5G versions), will take place on March 30, 2021 (April 10, 1400) with another different phone in The Mi Mix family continues to be a big difference from all the previous members of the series; The Mi Mix Fold, as its name implies, is Xiaomi's first clamshell phone, which in appearance should be compared to models such as Samsung's Galaxy Z Fold2 and Huawei's Mate X2. The main screen of this phone is bent inwards and another screen can be seen outside. Mix Fold, of course (closed) is thicker and weighs more than the other two competitors.

    Xiaomi Mi Mix series has been a place to showcase the company's innovative ideas for the past 5 years, and each model has had new charms, especially in the field of display; Among these innovations is the original Mi Mix and its successor, the Mi Mix 2, to which today's full-screen displays seem to owe a debt. The Mi Mix 3 slid the selfie camera to the back, and the Mi Mix Alpha concept phone used a screen around the phone. Mi Mix Fold, unlike other innovative members of this series, does not look very different, and despite some new points in design and implementation, and on top of them, the idea of ​​a liquid telephoto camera lens, it can be considered a similar product and close to other common foldable phones. .

    In the first step, get acquainted with Mi Mix Fold from its U-shaped hinge According to the manufacturer, it has resulted in a 27% weight loss compared to other competitors. Xiaomi means this weight loss, of course, apparently belongs to the hinge itself, because the total weight of the device (317 grams in the regular version and 332 grams in the special ceramic version) compared to both Mate X2 weighing 295 grams and Galaxy Z Fold2 5G weighing 282 The heat seems much heavier. Mix Fold, according to the manufacturer, 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 in both cases has been confirmed. .

    Mix Fold has a length of 173.27 mm, which is comparable to a meat With a length of 161.8 mm, the X2 speaks of a big difference; This difference should be attributed above all to the different aspect ratios of the two models, and to be sure of their width; The width of the Mix Fold in both closed and open modes is 69.8 and 133.38 mm, respectively, which are both much smaller than the width of the Mate X2 in these two modes, ie 74.6 and 145.8 mm. In other words, the Mix Fold in the closed position is more elongated and narrower than both the Mate X2 and Galaxy Z Fold2, and although it may not seem easy to access all parts of the external display with one hand, it can fit better in the hand with less width. To take. As mentioned, the weight of the device in the normal and ceramic versions is 317 and 332 grams, respectively, which is much more than usual for a mobile phone.

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

    External display of the device, which according to Xiaomi is the largest example in this category It is a 6.5-inch 90Hz AMOLED model with a resolution of 840 x 2520 pixels, which creates a 27: 9 aspect ratio. For comparison, the second Z Fold2 display is a 6.2-inch 60Hz model with a resolution of 816 × 2260 pixels and a 25: 9 aspect ratio, and the Mate X2 has a 6.45-inch 90-Hz display with a resolution of 1160 × 2700 pixels 21: 9. The normal brightness of this screen is 650 nits and its maximum brightness reaches 900 nits. Other notable features of this panel include 180Hz touch sampling speed and support for HDR10 +. At the top of this screen, on the left side, we find the only selfie camera of this model, which has a resolution of 20 megapixels and supports 1080p/30/60fps video recording.

    The charm of Mix Fold comes naturally, of course, by opening the device and making the main screen appear. begins; The phone uses an 8.01-inch OLED display with a 4: 3 aspect ratio, which Xiaomi calls the largest foldable display on the market today. The screen resolution is 1860 x 2480 pixels, which results in a density of 387 pixels per inch. The brightness of this panel is announced as 600nits and it uses a contrast of 4,300: 000: 1. Support for DCI-P3 and DolbyVision color zones are other features announced on this screen. The Mix Fold's internal display is a 60Hz sample with a 120Hz touch capture rate, both lower than the Mate X2 with a 90Hz panel and a 180Hz touch capture rate.

    A separate desktop mode is defined for this display, which looks like a tablet. And you can move three fingers on the panel at the same time to activate it.

    https://mobiletony.com M < Another attraction of Mix Fold belongs to the video section and its camera set, which is doubly attractive with the presence of Xiaomi's new Surge C1 video signal signal processor (ISP). The processor in the Xiaomi suite is not new, of course, and the company had already unveiled the Surge S1 chip in early 2017. The Surge C1 chip, which Xiaomi considers to be the result of two years of continuous work and research and spending 140 million yuan in research and development, supports the implementation of three algorithms: autofocus, automatic illumination and automatic water balance with more energy efficiency.

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

    The main 108-megapixel camera uses the 1/1.52-inch Samsung HM2 sensor Its pixels, after combining 9 adjacent cells, reach large dimensions of 2.1 microns in the default resolution of 12 megapixels. This camera apparently lacks OIS or optical image stabilization, which due to the very high price range of the device, makes an obvious negative point to Xiaomi's account. The lens in front of this sensor has 7 steps and its aperture is declared f/1.75. The maximum video 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.

    Mix Fold In addition to these two cameras, there is another 13-megapixel ultraviolet unit. Creates a wide-angle image with a 123-degree angle. This camera apparently lacks autofocus and its aperture is f/2.4.

    https://mobiletony.com M < As expected, the device processor is a 5-nanometer Snapdragon 888 processor, which uses a 2.84 GHz Cortex X1 core at the highest level, and in the other two clusters, respectively, 3 2.42 GHz Arm Cortex-A78 cores and 4 1.8 GHz A55 cores, respectively. Taken. Adreno 660 is also responsible for graphics processing in this chipset. The device's LPDDR5‌ RAM is 12 or 16 GB and has 256 or 512 GB of UFS 3.1 internal memory.

    Cooling mechanism of this model is another interesting point that should be mentioned This mechanism The manufacturer, known as the butterfly-type, occupies a large area of ​​22,583 mm2 and, with a combination of a large steam chamber, thermal gel and multiple layers of graphite sheets, heats not only the processing chipset but also the 5G antennas and fast phone charging system go away.

    Another attraction of Mix Fold, which is almost another example of it in mobile phones Can not be found, the presence of 4 speakers in the structure of this model, two numbers on the left and two numbers on the right side of the screen (in the open mode in the horizontal mode) and like other new flagships of Xiaomi Mi 11 series are adjusted by Harman/Kardon have became. The model's 1216-line speakers are powered by powerful 15V amplifiers, which Xiaomi says produce up to 40% more noise than the Mi 10 Pro. Another interesting thing about the quad speakers of this model belongs to their spatial sound algorithm, which determines the pervasive audio experience.

    The battery capacity of the device is 5,020mAh, which is compared to the 4,500 mAh battery Both Mate X2 and Z Fold2 have more capacity and part of the weight of the device should be attributed to this battery. The battery is powered by a fast 67-watt charger that will be able to fully charge in just 37 minutes. Wireless charging is apparently not supported on this phone.
