XIAOMI REDMI K20 REVIEW

XIAOMI REDMI K20 DETAILED REVIEW
The mid-range smartphone segment has a new contender, and it isn’t one companies should be taking lightly. The Redmi K20 comes packing a Qualcomm Snapdragon 730, the first mid-range smartphone to do so, giving it an obvious advantage over the existing devices in the market. Hot on the heals of the Realme X, we have the Redmi K20, priced slightly higher, but is that price difference worth it? We’ve got answers.

 PERFORMANCE
The Redmi K20 has the first mover’s advantage of bringing the Snapdragon 730. What that means is that for now, it tops out our performance charts. First, let’s talk CPU Performance. On our AnTuTu test, we see the Snapdragon 730 powered Redmi K20 blast past the Realme X with a score of 215186, almost 28 percent higher than the Realme X’s 168272. This kind of performance difference is further confirmed by our Geekbench numbers. For single core performance, The Redmi K20 has a score of 2543, 74 percent higher than the Realme X’s 1455. This difference in performance can be attributed to the fact that the big cores on the SD730 are based on ARM’s Cortex A76 while on the SD71, its Cortex A75. On multi-core test, the performance difference is a little more modest, with the K20 scoring 6963 and the Realme X getting 5968. Mobile Xprt scores also put the Redmi ahead by anywhere between 17 to 36 percent, depending on the level of photo manipulation.

CAMERA
The Redmi K20 sports three cameras on the back, each with a function. There is a 48-megapixel primary camera. This is a Sony IMX 582 sensor, identical in every way to the IMX 586, save for its limit of frame rates when it comes to shooting 4K video. Other than that, their performance is supposed to be the same. We also have an 8 megapixel 2x telephoto lens and a 13 megapixel ultra wide camera (12mm). Neither of the cameras offer optical image stabilization and only offer EIS, so final focal lengths could vary depending on the amount of shake detected by the camera.
Testing the primary camera first, we note that the binned results (default shooting mode) is excellent with impressive center sharpness. The edges tend to lose sharpness a little, but that’s only visible if you’re shooting a large group of people or shooting something close up. The 48 megapixel output of the same scene, however, shows a great lack of sharpness and contrast. Evaluating the 48MP images by themselves, we feel the results are definitely unimpressive, but kick the camera into the regular 12 MP mode and we have a winner on our hands. The HDR algorithms handle backlighting fairly well. As we have seen on several other phones before the Redmi K20, the 48MP sensor has great output during the day.

DISPLAY
The third impressive feature of this phone is the display. Xiaomi has managed to put an HDR certified display on the Redmi K20, making this phone a natural choice for those who enjoy streaming content from Netflix and YouTube. Yes, the Redmi K20 is certified by Netflix and YouTube to playback HDR content.

Thanks to the use of an AMOLED panel instead of IPS-LCD, we not only get better colour but also great brightness levels. The Redmi K20 topped out at a more-than-adequate 589 lux in our testing, with a minimum brightness of 4 lux. While this isn’t the brightest display by any means, it is still quite something to look at.

BATTERY LIFE
How far does 4000mAh get you? Well, according to Geekbench’s battery test, as far as 12 hours of continuous use. According to our video loop test, you can get round-about 652 minutes of video playback, although this number will vary based on what you play. We also noted only a 6 percent drop in battery percentage while navigating for one hour and a 4 percent battery drop during our 15 minute round of PubG. The phone takes 110 minutes to charge from zero to 100 and that’s because the K20 supports 18W fast charging, and not faster. In our daily use, the phone easily lasted a day and a half of medium-to-heavy use. Although it should be noted that we used the phone with the interface set to dark mode. Suffice to say, we have no complaints here, although we would have loved faster charging.
