Xiaomi Mi Mix 4 Review: Hidden Selfie Camera Under Smartphone Screen

After my next full testing of the flagship smartphone model Xiaomi Mi Mix 4, I was left with only good and pleasant impressions. For example, one of the advantages I can attribute is the high-quality materials used. For example, the back of the case was made of ceramic, and the front had Gorilla Glass Victus. Also, I did not find any special complaints about the assembly of the device. As for the screen, it also pleased me with its brightness and the presence of great functionality. It’s 120Hz refresh rate, HDR10 +, and more. The performance of the smartphone was also excellent, as demonstrated by the synthetic benchmarks and games. At the same time, I cannot say that the camera showed itself from the bad side, since on board the 108 MP device the sensor shot bright and rich photos and videos. And, of course, battery life was also good, but only when using a 60 Hz refresh rate. Also, the presence of fast charging will allow you to charge the device up to almost 100% for 15-20 minutes.

Xiaomi Mi MIX 4 also has the most luxurious fast charge. To be precise, it is a wired super fast charge of up to 120W and a standard 50W wireless super fast charge. No matter which charging method you prefer, Mi MIX 4 can let you have the fastest charging speed, and the 4500mAh battery is not small.

Model:

Xiaomi MIX 4 is a smartphone that claims to be the pioneer of full screen. Ever since the concept of the full screen was proposed, the market has experienced screen scaling, bangs, water droplets, and perforations from year 2016 to 2021, Finally now smartphones achieve true full screen by having an under-screen camera. Xiaomi used a 6.67-inch Huaxing Optoelectronics AM OLED 1080P pearl screen, which is a diamond-like arrangement. It is theoretically better in resolution than the shadow arrangement. It supports 120Hz refresh rate and 480Hz touch sampling rate, as well as these and other features. The surface is covered with Corning Gorilla Victus glass, and the front is much more resistant to fall than the back. This generation of MIX 4 has an all-in-one ceramic body. Taking into account the addition of ceramic material, the weight of 225g is not bad. The texture and unique luster of the ceramic material can cause it to be heavier. The phone also added screen fingerprints and dual light sensors. Although the edge of the Mi MIX 4 is curved, the curved surface is only slightly curved. The front look and feel are like a straight screen, which takes care of the hand feel and compares to the conventional curved screen edge. MIX 4 also debuted the Snapdragon flagship core 888Plus in the second half of the year, which is featured in the MIX 4. Based on 888, this SoC increased the X1 ultra-large core frequency to 3.0GHz, and the AI performance increased by 23%. It also has LPDDR5 RAM and UFS 3.1 storage and has a graphene soaking plate to better control the temperature.

 

The MIX 4 also gave the best in terms of charging, 120W wired fast charging and 100W wireless fast charging. It is worth mentioning that Xiaomi offers different charging modes this time. In the fast mode, it only takes 15 minutes and 28 minutes for wired and wireless to fill the phone. If you want to charge at "normal temperature" with greater peace of mind, it only takes 21 minutes and 45 minutes to fill the device with wired or wireless. As for the camera, the rear camera consists of 108MP main camera (ISOCELL Bright HMX sensor with optical anti-shake, 7P lens), 13MP ultra-wide angle (using its own curved lens) and 8MP periscope 5x telephoto end (with optical anti-shake) The focal lengths are 12mm, 24mm and 120mm respectively. In addition, this phone also has dual stereo speakers tuned by Harman Kardon (1014 and 1216P super linear speakers on the top and bottom), built-in multifunctional NFC, infrared module and X-axis linear motor, and has an increasingly popular UWB Features. Considering that there are not many Xiaomi products that support UWB at present, the factory also prepares a "One Finger Connecting Companion" so that you can use it with an existing device. Finally, in the system, the factory also added a new anti-lost mode, system-level translation, AI subtitles, voiceprint noise reduction and other functions. In conclusion, Xiaomi MIX 4 is a great choice for users who want an upgrade. It features top notch performance and great looking design which is suitable for any users who want a fresh experience.
