  • Pretty dang good

    There's only a few kinks. For one, I wish MIUI chose which process to kill to save on battery a bit better than it currently does. It took a while to get Snapchat notifications to show as a result of that. Secondly, the navbar buttons could use a bit more adjustment than MIUI allows. Lastly, and this is the biggest issue, MIUI on the China releases of phones doesn't allow you to change the launcher to anything other than what Xiaomi approves of. So you're basically stuck with either the Poco launcher or the stock launcher. I couldn't find out any way to get the Google news feed on either of them so that was a bit of a shame. Other than those kinks the phone is great.

    Pros
    • Display
    • Performance
    • Battery life
    • Charging speed
    Cons
    • A few things with MIUI (that can somewhat be solved by getting the Poco F3, the global version of this)

    Very powerful phone with super fast charging

    Performance in games is very high, you can play any games at ultra settings with at 120Hz and 60fps minimum. Screen 120 hertz amoled works smoothly eyes do not hurt there is a function of converting 60fps video to 120 works bright colors Charging from 20% to 100% in 29 minutes and autonomy for the whole day. The camera is good, especially the macro camera, it has various functions and effects for shooting video. Stereo speakers sound quality. The only drawback is the location of the fingerprint. I am very pleased with the purchase

    The best in the market quality price

    A mobile for about 500 euros with 12gb of ram and 256gb of memory, the best components on the market, no rival can face it

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.
