Technical sheet of Xiaomi Mi 9T

Description

The 2019 year seems to be the moment in which Xiaomi has decided to mark the rules of the game in the mobile market and again surprises us with a mobile that will meet the needs of 90% of standard users. It is a medium-high range with great features.

Borderless design We forget the notch

Its "borderless" format is its main weapon in terms of design refers. He does it by using a retractable camera and forgetting the notch, so hated by some. As if that were not enough, Xiaomi has not wanted to save on this aspect and has decided to incorporate a supermoled screen, so that we can enjoy the best graphics in our games. Xiaomi wanted to let us choose between different colors: black, blue and red, each more beautiful than the previous one.

Great cameras

Perhaps one of the highlights of this flagship are its cameras. In the back we will enjoy a camera with 3 lenses that will delight anyone. On the one hand, we will have a main sensor Sony IMX582 of 48 Megapixels with an aperture of f/1.75 capable of realizing its full potential in photos with less light, all of this helped by a sensor size of 1/2.25. A second lens helps us to get the farthest photos thanks to its optical zoom, in this case it is an Omnivision OV8865 sensor with an aperture of f/2.4 Finally and perhaps the most interesting of the three, a lens with Ultra Wide Angle It will help us with those landscapes where we want to capture everything in a single shot, or those photos of friends where the group has become too large to fit in a “standard” photo. And the most innovative feature of this mobile: the use of a retractable camera for selfies, which is taken out and inserted as we need it. It is not the first mobile that uses this technology, and it will surely not be the last, but we have to say that Xiaomi has managed to incorporate this functionality to this terminal in a very successful way. In this case it is a sensor with 20 Mpx that will allow us to obtain the best captures of ourselves.

More than enough Battery

Its 4000mAh are more than enough to move the whole set and will not be all the time pending if we have enough charge. In addition, Xiaomi has incorporated fast charging of 27W, which allows us to put our mobile from 0 to 100 in less than 50 minutes and a wireless charging of 18W that will make us forget the cables, or use the increasingly frequent charging spaces Wireless of our cars.

Enough processor for most

In this case, Xiaomi has opted for a mid-high-end processor, the Qualcomm Snapdragon 730. Surely one of the best and most capable of this range that allows us to enjoy any type of content and our most demanding games, although it is true that it is not a top-of-the-range processor and we may have to sacrifice some aspects when we want to squeeze it beyond its possibilities.

And all this seasoned with

If all of the above has seemed not enough, Xiaomi has not wanted to forget about the NFC, which allows us to make payments wirelessly. It also incorporates FM Radio, something not very common in the latest mobile phones that go on the market. And without forgetting a great unlock by fingerprint on screen that works perfectly in most situations. Xiaomi did not want to forget about the software and has updated this phone to the latest version of Android 10 with its own MIUI 11 customization layer.

Ki Cost-effective
Score
Not available
What is a Ki score?
Ki is an automatic score based on the specifications and prices of devices. It is calculated using over 200 variables to rank smartphones, tablets and other devices from best to worst.
How do we calculate the Ki?

In this case, to determine the score we evaluate 5 general aspects:

  • Design and screen
  • Hardware and performance
  • Camera
  • Connectivity
  • Battery

Once these 5 factors have been rated, we introduce the price variable. This means that any two devices with the same ratings get a different Ki score for quality vs price.

Even a device objectively worse than another may have a higher Ki score if it has a better price.

Does the Ki score change?

The Ki varies as time goes by. As new devices with better specifications enter the market the Ki score of older devices will go down, always being compensated of their decrease in price.
