  • Smartphone with no optimization

    I bought the phone cause it looked great and had dual speaker and great specs and an "OK" camera.

    After some months i can say that i would not buy that phone again!
    The overall performance is good for low graphic games like coc ... but if you play hard games it starts so smooth with 60fps. Then it gets hot like shit and starts lagging ... (internet was about 30Mbit/s download and 20Mbit/s upload, so it could not be the internet problem...
    We have about 30°C here in summer like usually but when the phone gets warm in the car or somewhere else where it is warm everthing starts lagging as fuck... you cannot use the phone normally then.

    I thought i should ask the support about the phone...

    Support wrote me for that problem" dont use the phone when it is hot and dont play hardcore games"...
    Wow ... This is the same if you buy a BMW and they say "dont drive more than 100km/h otherwise the car will work just with 10%"...

    Never coolpad again No support, no update no nothing..

    Quality / Price pretty good

    I got the phone for the battery and the hardware features and it did not disappoint me. The performance is very good and the battery is quite durable. I put it to charge almost every night with a 35% approx. battery after all the day of use (some navigation, social networks, calls). The sound is pretty good, You have to keep in mind that it's a mobile phone and not a stereo, so it sounds pretty good.

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.
