  • Nice price and with Advertising aspect camera

    I don't understand why used 4 lens weakly necessary ? I prefer used been one lens or two( maybe second 2 megapixels just for depth and portrait) Instead of using four weak, for what? For fake show design? Is Xiaomi still trying to make a phone with low quality parts with a fake design, like brands low quality their level!!!(I'm just talking about this model that really disappointed me with the policy of using four bad lenses)?

  • best entry-level 2020

    I have tried several entry-smartphones of well-known brands and this Redmi 9 is the closest to perfection.
    Nice FHD IPS display, battery that covers up to two days (one safe for heavy use), the camera is the best among phones in this range.
    Fast telephone operations and good reception. Present a very adherent case even challenging to remove .
    Expecting more from a cheap phone is absolutely ridiculous. Spend more money for more quality.

    A cell phone is very good for gaming and networking;)

    I bought the Redmi 9 and the truth is I am very surprised by its performance, I come from a Samsung J7 2015 and the change was very big. So far I have not given a failure, if you do not want to spend a lot this cell phone will be great for you. It gave me 202,000 thousand points in antutu ufff being honest much better than a Samsung A51 in terms of performance and that costs practically half if you compare it with the price of the A51. The screen is FULL HD +, the cameras are good but at night if the quality drops, the brightness is somewhat low but you will only notice it if you are under the Sun, its performance and battery ufff great or if you are looking for Power and a good autonomy;)

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.
