  • very good overall phone but batterry with the years is pretty bad

    very good phone, have it for already 1 year and a half and its pretty decent. In my opinion you can stay with this xiaomi for 4 to 5 years, the only downgrade is the battery in long term.

  • Great phone, with a custom ROM

    I'm no big fan of MIUI, so I install an AOSP custom ROM. Since I imported it, I didn't have warranty anyway.

    Pros
    • Camera
    • Performance
    • AMOLED screen
    Cons
    • Not a huge DPI (although it helps with performance)

  • An exellent device compared to others with same price

    Unstable cellular connection, lost connection on SIM card frequenty, very unpleasant exp. Overall performance really good since it has snap 855 and 6gb of ram. The design quite good, having right corner cameras setup so you can hold it like a real camera, but the camera chunk rise so high, even a cover can't cover it. The UI works smooth, although sometimes it's a bit buggy but yeah.. it's Xiaomi specialty, be with it :v

    Pros
    • Quality camera
    • Powerful chipset
    • Nice design
    • Exellent screen quality
    Cons
    • 3300mAh battery
    • SIM card get update cause signal lost

  • A very nice phone for the budget, I think nothing can beat it.

    The design is so sleek. The battery is pretty ok since the Snapdragon 855 is a very power-efficient chip to start with. The power usage to performance ratio is so high. The cameras are top notch, though Xiaomi's software for noght mode could be improved. Gcam helps me with that. Video quality, especially the stabilization is the best. You can never be wrong in getting this phone. It's a steal. It's a BEAST!

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.
