Xiaomi 12 review

At the end of 2021, the Chinese company Xioami made several important announcements - the MIUI 13 interface and three flagships, representatives of the 12th series - Xiaomi 12, Xiaomi 12X and Xiaomi 12 Pro. According to her, the first device is the ideal flagship. It combines a powerful processor, stylish design, solid cameras and support for a range of innovative technologies. Whether this is the case, you can see in the following lines. From now on, however, we must warn you that the Xiaomi 12 will delight you with its compactness and beautiful OLED screen with a refresh rate of 120 Hz. Under its body is a new processor, and the battery will recharge super fast.

There is nothing disappointing in the look of the smartphone. It will meet the expectations of anyone who wants to hold a modern device. And quite compact. Its dimensions are more than acceptable, and it weighs less than 180 grams. In other words, the Xiaomi 12 works nicely for hours. It is lightweight, and this dignity is complemented by beautiful thin aluminum frames. The rounded edges of the body contribute to ergonomics.

You will find frosted glass on the back of the device. You may think that you will leave a lot of fingerprints on it, but in practice they are invisible.

The Chinese company has offered for Xiaomi 12 four colors - black, blue, green and pink. All are pleasantly gentle and unobtrusive.

The front camera is positioned as standard on the front of the smartphone. The slit is very small and not conspicuous. The screen occupies almost 90% of the entire panel, which is a high performance and an excellent feature for Xiaomi 12. In addition, you can count on the properties of tempered glass Corning Gorilla Glass Victus. However, there is no protection against dust and moisture.


This Xiaomi model has a 6.28-inch OLED display with a resolution of 1080 x 2400 pixels, which is a standard parameter for most flagships on the market. Bypassing the other features, we come across decent performance - 419 pixels per inch, 20: 9 aspect ratio and support for HDR + and Dolby Vision. The maximum brightness - 1100 nits, guarantees trouble-free reading of information when working outdoors on a sunny day.

Since the Xiaomi 12's screen has a maximum refresh rate of 120 Hz, you can count on a smooth picture. From the settings you can lower it to 90 or 60 Hz if necessary.


As already mentioned, Xiaomi 12 has a powerful processor and it literally is. Under its body is a new chipset Qualcomm Snapdragon 8 Gen1, which is made of 4-nm processor. Adreno 730 is responsible for the graphics, which has also been updated. So far, the parameters sound impressive, but there is more to be said.

Snapdragon 8 Gen1 is quite a powerful processor with an excellent cooling system, which guarantees a better level of efficiency. You will find it combined with three memory modifications - 8/128 GB, 8/256 GB and 12/256 GB. The RAM is type LPDDR5, and the storage - UFS 3.1. As the option to insert a memory card is not supported, it is recommended to bet on a modification with more internal memory. This way you will be sure that you will have enough space for everyday tasks and a bunch of memories.

By default, the smartphone runs Android 11 and the new MIUI 13 interface. It runs smoothly and quickly.


Xiaomi 12 is equipped with a triple rear camera, which consists of a main 50-megapixel module Sony IMX766, ultra-wide-angle 13-megapixel sensor and 5-megapixel telephoto macro sensor. You can expect good photos from this set. The quality of the night photos tends to average.

If you like to record videos, their quality will be a maximum of 8K at 24 frames per second. With the ultra-wide angle sensor, they will be only 4K at 30 frames per second. The presence of optical stabilization somewhat improves the final results.

The front camera of the Xiaomi 12 is 32-megapixel and makes selfies satisfying. In the menu you will find standard shooting modes.

In other words, the photo capabilities of the phone are normal, although it is one of the flagships. A compromise has obviously been made here.

Autonomous work

Xiaomi 12 has a battery with a capacity of 4500 mAh. A huge plus is the support of wireless charging with a power of 50W. This means that you will recharge the battery from 0 to 100% in just 39 minutes.

You can also use wired fast charging, and the power is even more impressive - 67W. Recharging is also available, making the Xiaomi 12 a valuable external battery.

As a stand-alone operation, the smartphone remains at the level of the company's previous flagship. For some reason, the developers have decided to bet on a higher refresh rate, cutting the possibilities for longer battery life on a single charge.


Xiaomi 12 is definitely a good flagship that can be yours at an affordable price. It will appeal to anyone looking for a compact device and playing medium-resource-intensive games and applications. Heavier tasks can cause the cabinet to heat up.

Xiaomi 12 handles everyday tasks flawlessly. The capabilities of its cameras are enough for good photos and videos, but not for the exciting results that can offer you flagships of competitors.

Finally, we must mention another advantage of the smartphone - excellent sound. The manufacturer has used Harman Kardon, which should ensure a strong, rich and clear sound.
