News unit EMGblog.com : Company Xiaomi on Wednesday, August 10, 2021 (19 August 1400) along with the introduction of Mi Pad 5 and Mi Pad 5 Pro tablets from the latest flagship of the Mix series It has also unveiled the Mix 4; Mix 4 should be a follow-up to Mi Mix 3 company. Xiaomi knew that it was unveiled three years ago in October 2018. Mix series in this company’s products has always been accompanied by new innovations, including the first real full-screen panel in Mi Mix, ceramic coating present in Mi Mix 2 and sliding structure Mi Mix 3 pointed out. Mix 4 has also continued this process with the brand’s first in-screen camera, 120W super fast charger and UWB connection.

In-display selfie camera

Speaking of Mix 4 should definitely be started from the in-screen selfie camera where after Axon 20 and Axon 30 ZTE, Xiaomi practically becomes the second brand that has displayed this feature in the form of a commercial product, although the company

Like other notable examples in this field such as The third generation of Oppo technology to use the camera under the display layer, here too, the size of the pixels in the selfie camera area has been reduced to allow more light to pass through, the pixel density of this part still equal to 400ppi and similar to other parts of the screen. The shape of the colored pixels has also been changed, with a diamond shape that Xiaomi calls it Micro Diamond. In terms of brightness, color and other image measurement elements, the image in this area is the same as the rest of the panel, and thus the camera is completely hidden from view.

Xiaomi also combines the software and hardware capabilities of the high quality of photos and videos taken in the selfie camera. has ensured; This is achieved by minimizing light refraction thanks to a new design in the circuit of this part and a new transparent curved wiring system made of ITO or Indium Tin Oxide in combination with different imaging algorithms.

The selfie camera of this phone is a sample of 20 A megapixel has a pixel size of 0.8 microns, which after combining four adjacent cells reaches 1.6 microns in a resolution of 5 megapixels. Autofocus apparently has no place in this camera, and the aperture of this lens is not mentioned in the specifications of the device.

Screen

Going past the selfie camera, we can mention the screen itself, which is a 6.67-inch 10-bit AMOLED sample with Curved edges and a resolution of 1080 x 2400 pixels with a refresh rate of 120 Hz and refreshes 480 times per second to accommodate finger touches. The contrast ratio of this screen is declared to be 5,000,000:1 and it also supports Dolby Vision and HDR10+. As expected, the color accuracy of this display is also at a high level and in addition to supporting the DCI-P3 color spectrum, it also provides JNCD≈0.34 and dE≈0.40 indices. This screen is like Mi 11 Ultra with a coating of

The device’s optical fingerprint sensor is also placed inside the same screen.

Design and appearance of the device

Mix 4 At first glance, it doesn’t look much like Mi 11 Ultra doesn’t look like it; Where the full-screen display and the special shape of the rear cameras speak of the similarities between these two models. The body of this model, like the previous generations of this family, consists of an advanced unibody ceramic design that has been baked three times at 1,400 degrees Celsius, and despite maintaining high strength and durability, it has become 30% lighter than before.

Mix ceramic 4 Chinese dishes of Song dynasty (including the dynasties ruling China between 960 and 1279 AD) ) and its new gray color is also made with a rare metal material as a colorant in a special baking process with a temperature between plus and minus 5 degrees. In this special color, green and light blue tones are also used, which make it a unique example.

The dimensions of the device are 8 x 75.3 x 162.6 mm, which is smaller than a normal Xiaomi phone like Redmi Note 10 Pro with the same screen size in length and width with a certain reduction It is accompanied by importing a more advanced phone from the same brand such as Mi 11X Pro also still maintains its superiority in length and width despite the greater thickness of Mix 4.

This phone is not as light as expected and leaving Mix 2, like other members of this family, weighs more than 200 grams and 225 grams to be exact.

Main cameras

The main camera of the Mix 4 is a 108-megapixel model Samsung ISOCELL HMX has a 1/1.33 inch sensor that The aperture of the 7-step lens in front of it is f/1.95 and it also uses optical image stabilization or OIS. This camera supports recording 8K video at 24 frames per second, and 4K and 1080p at 30 or 60 frames per second and slow motion at a maximum of 480 frames per second.

The second camera is an 8-megapixel telephoto with a 120 mm lens. It is a periscope that provides the equivalent of 5x optical zoom. This camera, which has OIS and automatic focus in its list of features, can reach 50 times zoom by using digital zoom.

The third camera of this part, which is smaller than the others and aligned with the main camera, is a 13 megapixel ultrawide with The 6-step Free-form lens has an aperture of f/2.2 and depicts a 120-degree field of view.

Processor and memory

Xiaomi to process Qualcomm’s latest achievement, Snapdragon 888 has gone from a 2.99 GHz core Cortex-X1 processor, three 2.42 GHz cores A78 and 4 cores 1.8 GHz A55 architectures, and its graphics is still Adreno 660. As usual, the memory slot has no place in this phone, but by equipping it with 128, 256 or 512 GB of UFS 3.1 internal memory, it has eased the imagination of users in terms of storage space. The RAM of the phone is 8 or 12 GB of LPDDR5 type, the 8 memory is offered only in two versions of 128 and 256 GB, and the 12 GB RAM is available in two versions of 256 and 512 GB.

To reduce as much as possible the heat and transfer the generated heat Outside, a 3D graphene plate with an area of ​​1,232 mm2 is used, which covers the motherboard area. The entire heat transfer part in this phone, apart from this graphene plate, is of course completely larger and has an area of ​​11,588 square millimeters.

Battery and charger

Mix 4 is equipped with a relatively large battery with a capacity of 4,500mAh, which compared to Mi 11 Ultra’s 5,000mAh battery has been reduced by 10%. This reduction, of course, is completely compensated by the device’s 120 W fast wired charger, and while the Mi 11 Ultra needed 36 minutes to fully charge with its 67 W charger, this figure in Mix 4 is only 15 minutes (in boost mode and 21 minutes in default mode) is reached. Wireless charging has not been forgotten in this phone and it supports a very high power of 50 watts in this mode. In this situation, Mix 4 needs only 28 minutes of time (in boost mode and 45 minutes in default mode) to fill the battery.

Communication options

At the top of communication options Mix 4 should be UWB pointed out that to date only in some high-end phones including the iPhone 12, Galaxy S21+ and S21 Ultra was present. This option is intended to exchange information at short distances with minimum energy and it can be used to communicate with devices based on the Internet of Things, turn on the car, pass through smart doors without the need for a physical key, and other similar things. UWB is used in Mix 4 with a feature called Point to connect in combination with some smart home products, where it will be enough to quickly connect the device to AioT devices by holding the phone towards them.

Apart from this on the Mix 4 with 5G on both Independent and non-dependent mode (SA and NSA), Wi-Fi 6, Bluetooth version 5.2, NFC connection, infrared and GPS/GLONASS/BeiDou/Galileo/QZSS/NavIC satellite routers (two frequencies in Galileo, GPS and BeiDou). There is no headset jack in this phone, but the stereo speakers tuned by Harman Kardon will probably satisfy music fans.
