Let's consider in detail the technical characteristics, advantages, disadvantages of both options and compare them with each other.

Chinese brand Xiaomi

Xiaomi equipment has been known to the Russian buyer for five years. In terms of sales, the company ranks 4th in the PRC and 6th in the world. In our country, the goods are officially sold by the Svyaznoy chain of stores. Since 2016, the Redmi line of smartphones has been launched and is constantly being improved. Devices with a capacious battery, long battery life and high technical capabilities are offered at an affordable cost and belong to the budget. The rest of the company's smartphones are also produced according to the principle of high quality - average price. A feature of Xiaomi devices is the use of MIUI proprietary firmware - the styles of Samsung TouchWiz and Apple iOS perfectly coexist in it. There are two types of devices on the market: on a pure Android operating system and on Android using the MIUI shell.

Xiaomi Redmi Note 9 Pro and Pro Max

Appearance and design

Both models have a classic candybar appearance. The displays look similar: the frames are almost invisible, the chin is slightly wider than the top and side frames, in the center of the screen at the top there is a neat round peephole of the front camera. The dimensions of the Pro Max case are 165.5 x 76.7mm, the dimensions of the Pro are the same: 165.8 x 76.7mm. The ergonomics are good - the devices fit comfortably in a medium-sized hand. Matrix properties and battery capacity do not allow making a device with a small thickness, therefore the thickness of the models is the same and is 8.8 mm. Both devices weigh 209 grams. The bodies and frames of the devices are plastic.

5th generation Gorilla Glass is installed on top of the screens and cases. It protects smartphones from water and splashes, is considered waterproof, but if used carelessly, scratches, cracks and other mechanical damage may appear on top of the glass. For the greatest protection of devices, in order to avoid the appearance of matte fingerprints on the surface, it will be more convenient to put on a silicone case on smartphones. On the left side there is a card slot, on the right side there are power buttons, volume buttons and a fingerprint sensor. Both phones will hit the market in three colors: Aurora Blue, Glacier Ice White and Interstellar Black. The cost of Pro Max is indicated from 180 euros.

Screens and matrices

Each model is characterized by touch displays with matrices such as IPS LCD, with liquid crystal indicators. Capacitive displays with multitouch function reflect 16 million shades and colors. At the request of the manufacturer, the brightness of the screens varies within 450 units. The IPS matrix prevents the installation of a fingerprint sensor inside the screen. The sensor is mounted on the right side, where the power / lock and volume buttons are located. Products are made with the same display diagonals - 6.67 inches. The total usable area of ​​the screens is 107.4 sq. Cm.The ratio of horizontal to vertical screen sizes is identical and standard, equal to 20: 9, the screen-to-body ratio of the smartphone for the Pro Max is 84.6%, for the 9 Pro - 84.5%. As for the number of pixels per inch of area, they are also equal: for both models, the manufacturer indicates the density of 395 units per inch. The resolution of both screens is the same and equal to 1080 x 2400 pixels, the output is FullHD + format.

When watching movies, the feeling of being at the screen of a large LCD TV is created. The IPS liquid crystal matrices provide high contrast, lifelike tints and natural color rendition. The picture is smoothed, it is visible in any conditions: both in the dark and in bright sunlight. This is the main advantage of the IPS matrix. Among other advantages, the viewing angles of the display can be noted - they show the picture as much as possible without distorting it. An important aspect is the transfer of deep blacks. Of the minuses, it is worth noting the response time of the screen - IPS has it less than all modern cool matrices such as AMOLED and Super AMOLED. This is not noticeable to the human eye. For liquid crystal matrices, the installation of capacitive storage batteries is characteristic, which provide energy saving and long autonomy of devices.

Processor and memory

With multimedia shooting, a large amount of photo and video is obtained. To hold and process such information requires a good amount of RAM. Therefore, the Pro Max smartphone provides 6 and 8 GB of RAM, in the Pro - 4/6 GB, tk. cameras in it are of lower resolution. It is controlled by an 8-core Octa-core processor with Qualcomm SM7125 Snapdragon 720G chipset in 8nm process technology, with powerful GPU Adreno 618 graphics. The accelerator is responsible for smooth operation when scrolling through the menu and Internet pages. The core architecture is as follows: two Kryo 465 Gold cores with a frequency of 2.3 GHz, six Kryo 465 Silver cores operate at a frequency of 1.8 GHz. On the market there are Pro Max models with UFS 2.1 memory of 64/6, 128/6, 128/8 GB, Pro models with 64/4, 128/6 GB volumes. The new products have a dedicated slot for installing a microSDXC card with additional memory up to 512 GB. The operating system used Android 10.0 is decorated with its own development - MIUI 11. The shell is similar to the joint solutions of IOS and Android, includes an accessible easy menu, proprietary applications, improves the performance of devices.

Wired and wireless technologies

Smartphones operate on three main network technologies - 2G GSM, 3G HSPA, 4G LTE; data transmission is carried out at HSPA speed 42.2 / 5.76 Mbit / s. The slot accepts one or two Nano-SIM cards operating in dual standby mode. Among the wireless technologies are Bluetooth 5.0, dual-band Wi-Fi 802.11, with access point and Wi-Fi Direct, infrared sensor. Antennas are built inside for listening to FM radio, there is a recording function for it. The search is carried out using GPS navigation systems, with A-GPS, GALILEO, GLONASS, BDS, NavIC. Among wired communications, there is a USB 2.0 connector, a reversible Type-C 1.0, a mini-Jack with a diameter of 3.5 mm for connecting a headset.

Battery

A non-removable Li-Po battery with a capacity of 5020 mAh ensures long-term autonomy of both devices. According to the manufacturer, 33W fast charging will charge the devices in half an hour from zero to 50%. You will have to check the information only after purchasing one of the devices.

Multimedia and macro cameras

The new products have single front cameras under the display and tetra-blocks on the back with the main cameras. Cameras provide high quality, excellent detailing of photos and videos in different lighting conditions and in different shooting modes.

The output is video of the following dimensions: 2160pix x 30 fps, 1080pix x 30/60/120 fps, 720pix x 960 fps.The EIS stabilizer fixes the movement of the device along three planes, making the image clearer and more stable.

The smartphone saves photos in uncompressed RAW format. The format contains raw information that comes directly from the camera sensor. Further, with the help of photo editors, you can carry out any processing of images. If you just need to take a high-quality photo and send it immediately, for example, to Instagram, there is a Pro Color function that makes photos more detailed and vivid.

The ultra-wide camera captures a 119-degree field of view. Pictures through it are lighter and more detailed than on smartphones from other companies.

A macro camera will allow you to photograph an object at a distance of 2 - 10 cm. Portrait photography is performed with the bokeh effect, when the face looks sharp, and the picture around is blurred, and the frame looks lively.
