Technical sheet of Xiaomi Mi 9

Description

First terminal of Xiaomi in the year 2019. The design with a water drop-shaped notch, reminds a lot of that of the Huawei Mate 20, and is similar to that already used in the Redmi Note 7.

GREAT SCREEN

The Amoled Samsung screen, which is from 6.39 "and with a FullHD + resolution has a brightness of up to 600 nits, Xiaomi has incorporated a Sunlight 2.0 mode, to improve contrast and optimize colors outside, so that it allows us to correctly display the screen in any situation.

It also adds an option to set the screen brightness to a minimum and still maintain a good level of contrast and color, as well as an improved reading mode, aimed at improving visibility in low light. According to Xiaomi we find a terminal with a loudspeaker much more powerful than the previous model, reaching a higher volume level thanks to the DMS dynamic gain control system, unfortunately they still do not incorporate 3.5mm jack or FM radio.

The fingerprint reader, located under the screen glass, makes use of optical technology as in the Xiaomi Mi 8 Explorer Edition. Xiaomi, has improved the accuracy and speed becoming 25% more with a larger size for the area of ​​fingerprint detection.

A KNOWLEGED DESIGN

In the design section, although the changes are not drastic, Xiaomi has opted for a glass finish, with colors with degraded finishes using a laser engraving process and with a double layer coating. The rear panel is curved on all four sides to improve ergonomics.

POWER POWER POWER....

We are facing the first Xiaomi phone to incorporate the Qualcomm Snapdragon 855 processor, accompanied by 6 or 8GB of LPDD4x RAM and 128 and 256GB storage. The Transparent special version, with the image of Battle Angle, has several differences, on the one hand it comes in a single version of 12GB of RAM and 256GB of storage, and the camera has improved the aperture to f/1.47, all with a exclusive exclusive with the back showing components of the mobile, not the real ones, which already caused quite a bit of controversy in the Mi 8.

A MISERABLE BATTERY WITH GIFTS

The battery, with a capacity of 3,300 mAh, seems somewhat short compared to its competitors, but it incorporates a fast charging of 27 W and Qi wireless charging of 20W.

GREAT CAMERA

Regarding the photographic section, Xiaomi, has decided to mount the Sony IMX586 48MP sensor, with Pixel Binning technology, which groups 4 pixels in one to improve the capture of light and leaving the photo in 12MP resolution. Accompanying this main sensor, we have a Samsung 12MP telephoto lens to perform 2X Zoom and a third 16MP sensor with a 117º wide angle that is the Sony IMX481. In the video section, record up to 1080 in slow motion 960 fps, although as indicated by the Xiaomi tab, you have to wait for a software update to use it.

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.
