Smartphone Xiaomi Mi 9: advantages and disadvantages

The world of technology is developing very rapidly, and this is happening especially fast with the telecommunications market. Every day a new device appears in the world, which must be something better and must be different from others. Competition develops in parallel and at the same pace.

Xiaomi has already firmly taken the leading position on par with many manufacturers that still manage to win the attention and demand of the consumer. Although it is becoming more difficult every day due to the huge variety and great choice, both in quality and price.

Xiaomi's Mi lineup has decently replenished last year, performance has improved, platforms and operating systems have been updated. It would seem much better, but already at the end of 2018 there were rumors about a high-profile novelty. Presumably in the spring of 2019, the world will see a new Xiaomi Mi 9 model, or maybe it will be called something else.But the fact that it will be cooler and more sophisticated than its predecessors is clear even now.

Main technical parameters

Smartphone design

Mi 9 received a number of external changes from its manufacturer:

First of all, this is the size: the height will be 155 mm, the width is about 75 mm, but the thickness remains the same as that of the predecessor Mi 8, 7.6 millimeters. The phone has increased quite proportionally to the "grown up" screen.

Case - metal / glass. The back and front panels are made of high-quality glass from Corning - Gorilla Glass of the fifth and latest generation. This means that the glass body is now even stronger (four times) than before, even more resistant to drops. Now, according to all tests, even a fall from a height of 1.5 meters will not harm the smartphone.

The frame of the phone is made of 7000 series aluminum.This figure speaks for itself and guarantees three main benefits: increased strength, thinner walls and much lower weight. By the way, the weight of the model itself is not yet known for certain.

The front part of Xiaomi Mi 9 is almost frameless, because the frames are very thin and do not create any discomfort. The front camera is located in the upper part with a small droplet. A feature of this model is a fingerprint scanner, which is located slightly below the center of the front panel, that is, on the screen.

The "back" of the phone is smooth and pleasant to the touch. On the left in the upper corner is the place for the triple main camera, which is located vertically and has a very compact and neat appearance.

On the right side on the edge, you can easily find the well-known on / off buttons. and volume control. The bottom edge is a place for USB Type-C and a polyphonic speaker, as well as a microphone.

You can't even look for a standard mini-jack headphone jack in this model. There is a special input for the headset.

And, of course, the color variety of the case. The manufacturer has provided four colors for its new flagship device: black, white, gold and blue. An excellent solution that will enable the user to choose the shade of their choice.

• Comfortable size and weight of the model (although for some it may seem too big);
• Strength of body materials;
• Frameless "face";
• Choice of color.

• Dedicated headset jack;
• The usual USB has been replaced by USB Type-C.

Xiaomi Mi 9 smartphone display

The screen of the new premium device from Xiaomi has noticeably “grown up” and reached 6.4 inches.At the same time, thanks to the very thin, almost imperceptible frames, the display area seems even larger. It occupies over 80% of the total bezel size or 102.2 sq.cm.

Monitor type - super AMOLED capacitive touch, recognition and display - up to 16 million colors.

Moderate brightness, harmonious color saturation that fits perfectly into the 1080x2280 pixel resolution. With an aspect ratio of approximately 19:9, the density is approximately 394 ppi. These are very good figures even for this level of smartphone.

At the bottom of the screen is a fingerprint scanner. A rather unusual innovation that will definitely please users with convenience, speed and accuracy.

It is worth mentioning the reliable protection in the form of super durable glass of the fifth generation Corning Gorilla Glass.

• Large frameless screen;
• Reliable protection from Corning;
• Color brightness and good pixel resolution relative to the size of the screen itself;
• The fingerprint scanner is at the bottom of the screen, not on the back.

• Not detected.

Processor, performance and memory

In the new Xiaomi model, the Qualcomm Snapdragon 855 (7 nm) will supposedly “beat the heart”. Now this is not just an eight-core processor, but an assembled powerful mechanism, which consists of 4 small Cortex-A55 cores paired with three large cores based on the Arm Cortex-A76 design and the largest "primary" Cortex-A76 core, designed for higher peak performance, which is up to 45% higher than the previous version. At the same time, despite the improved performance, energy consumption is noticeably reduced, which allows you to extend the battery life of the device.

The chipset includes the Adreno 640 GPU, which has a number of improvements from gaming graphics (HDR pipeline for games) to video and photo images.

Memory Xiaomi Mi 9 is predicted in two versions: operating 6 GB + built-in 128 GB and operating 8 GB + built-in 256 GB without the possibility of additional expansion with a memory card. Although with such volumes of the built-in extension, it may not be necessary.

• Application of the latest platform;
• Up to 45% performance increase over the previous version;
• Upload/download speed, improve network performance;
• Gaming capabilities have increased, 3D images have appeared in games;
• With the improvement of the GPU, the photo and video capabilities of the device have improved;
• Good memory capacities in 2 versions (6/128 GB, 8/256 GB).

• Not detected.

Camera Specifications

The photo and video characteristics of the new Xiaomi smartphone have largely received their improvements from the use of a new platform in the device. After all, it is thanks to the graphics chip that the quality of photographs has been improved, it has become possible to make 3D images in videos, as well as in games.

The main camera of the Mi 9 is triple, it is located in the upper left corner of the back of the phone. These are two full-fledged cameras (48 Mp + 12 Mp) and a TOF camera (25 Mp).

TOF camera

It is worth stopping at the third TOF camera. What is it for and what does it represent. ToF stands for Time of Flight and is translated literally from English - flight time. It is also called a time-of-flight camera.At its core, this is not even a camera in the truest sense of the word, but a separate special sensor that emits light and fixes the speed of its reflection on an object that enters the picture. That is, the task of this camera is not the color of the image or its external indicators, but the distance. It is thanks to this “third eye” of the smartphone that the image is improved, as well as the fixation of 3D forms.

The features of the main camera include dual LED flash, HDR technology, panorama mode.

Camera resolution for video, respectively, in the same order: 2160 pixels at 30/60 fps, 1080 pixels at 30/120/240 fps, 720 pixels at 960 fps.

Selfie camera - 24 MP - a good indicator for frontal shots and very good for video images (1080 pixels 30 frames per second).

Auto focus + auto lighting and brightness - what else do you need for high-quality photos and videos.

The Xiaomi Mi 9 camera capabilities upon its release promise to be the best in its line of flagship devices.

• The main camera is triple and has good performance (48, 12, 25 MP);
• Availability of all necessary sensors for high-quality operation of cameras;
• The front camera has all the necessary properties;
• Dual LED flash main camera;
• HDR mode for photo processing.

• None.

Smartphone battery and battery life

Non-removable advanced design - 3500 mAh lithium polymer (Li-pol) battery with fast charging up to 32W. The capacity will be more than enough to work for 8-9 hours with the active use of the Internet and related programs.The processor part of the phone consumes energy economically and this allows you to reduce the load on the discharge / charge, thereby saving the life of the battery itself. Video viewing is possible up to 13-14 hours, audio listening is about 55 hours of continuous playback. The presence of such a battery in the device can be considered in two ways, since there are a lot of pros and cons.

• High energy density;
• Reduced level of self-discharge;
• Compact form;
• Endurance in a wide range of temperature conditions (-20 + 40).

• Fire hazard in case of overcharging or overheating of the battery;
• It is necessary to adhere to a certain scheme for charging the battery in order to extend its service life.

Based on the presented parameters and characteristics, the new flagship Xiaomi Mi 9 promises to win a wide range of adherents among users. Presumably, the price of a new miracle smartphone will range from 450 to 550 US dollars. This cost relative to the features offered is quite acceptable, because other brands offer the same performance at a much higher price. All this can only mean one thing: Xiaomi will not only strengthen its position, but also take a leading position among its competitors.
