  • No lo recomiendo

    Soy un usuario que le brinda más importancia a procesador, sonido, conexión automática a redes. Le brindo menos importancia a aspectos de fotografía.

    Es un móvil con un diseño muy grande, muy incómodo, mal reconocimiento de huellas, no reconoce de manera automática el cambio de redes (datos vs. Wifi) pero lo peor de todo es la calidad del sonido.

    Móviles con tecnologías de hace 3 años son iguales o mejores, a excepción de las dos cosas buenas mencionadas: resolución de pantalla y procesador.

  • Good phone value for money

    A good amoled screen with 120 Hz is, of course, a fat plus. The camera in daylight is quite good, but due to the new not fully optimized processor in night light, the phone makes a lot of noise in terms of photo.The processor is not too powerful, don't expect super performance.But 310k in antutu do a good job with games.For me, the phone in terms of price quality is good.But it could have been better.)I recommend the phone.

  • Great display, good specs overall, average camera performance

    Tested 2 units for 3 whole days each. Comes with pre-installed screen protector and free clear jelly case. 120Hz amoled display is bright enough and gives crisp colors to my casual experience. Camera performance is average, well lighted subjects and scenes are mostly OK, outdoor night shots even on night mode still looks terrible even if you compensated with better lighting. A bit disappointed that Xiaomi's own Game Turbo app was not included on the MiUI14 it came with but I was able to play Arknights well and a bit of Genshin Impact with acceptable graphic hiccups here and there. Wifi, mirror/cast, BT, GPS, mobile signals and FM radio works well. MicroSD and OTG also working fine. Sounds and audio quality on the single speaker are OK too but maybe tinny for audiophiles. The 5000mAh battery can last a day of moderate mobile phone usage and the included 33-watt charger and USB-type C cable charges from <10% to full in about 1.5 hours or so.

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.
