Design, Display, & Build

Moving to its design front, the Redmi K50i 5G looks familiar, the design offers a camera on the back with two big ones and a small one that might be familiar to you, so there’s nothing much special in the design. The back has a sparkling effect with reflections, however, the back isn’t glossy. The Redmi K50i 5G comes in three color variants – Stealth Black, Quick Silver, and Phantom Blue.

The surface on the back isn’t glass, but rather polycarbonate, we would like to see glass instead for premium quality. The sides are flat, the corners are round, and it gives a nice grip. The phone seems quite bulky, it’s 8.9 mm thick and weighs around 200 grams. We didn’t find any IP rating or water-resistant design on the phone.

On the front side, you will find a 6.6-inch Liquid FFS LCD display with Full HD+ resolution (2460 x 1080 pixels, 407 ppi) and a whopping 144 Hz refresh rate with 650 nits brightness. The phone offers an 85.1% screen-to-body ratio and is protected by Corning Gorilla Glass 5. The display highlights include Dolby Vision and HDR10 and offer a smooth 144 Hz refresh rate, likely to be useful for gamers.

Moving to the sides, you get a power key on the right side with a fingerprint scanner mounted on it, and volume control just beside it while the left side area is empty. The bottom side has dual slots for 5G SIMs, no microSD card slot is available, a USB Type-C port for fast charging and data transfer, a microphone (another at the top side), and a loudspeaker (stereo). The top side has another loudspeaker, an IR Blaster, and surprisingly a 3.5 mm port which is good.
