Redmi K50 Extreme Edition: Stunning Design, Comfortable to Hold

The front of the Redmi K50 Extreme Edition features a 6.7-inch OLED display with a resolution of 2,710 x 1,220 and a pixel density of approximately 356 PPI. Additionally, the device boasts a high refresh rate and touch sampling rate of 480 Hz, along with 12-bit color depth and a high frequency of 1,920 Hz, effectively eliminating PWM flickering.

The front camera of the Redmi K50 Extreme Edition is housed in a center-hole punch cutout on the screen, utilizing a Sony IMX596 20 MP sensor. The earpiece speaker is integrated into the frame, snug against the phone's edge. The screen bezels are very narrow, especially the chin, which helps to create a more expansive viewing experience.

The rear camera cluster of the Redmi K50 Extreme Edition features a layout similar to that of the Xiaomi Mi 12, with a large 100 MP main sensor at the top, an 8 MP ultra-wide lens, and a 2 MP macro lens at the bottom. To the right of these two secondary lenses is the dual-LED flash module.

The back of the Redmi K50 Extreme Edition is made of glass using AG matte processing technology, with deeply curved edges, providing a more ergonomic grip and a comfortable feel.

At the top edge of the Redmi K50 Extreme Edition, you'll find the speaker system, noise-canceling microphone, and infrared remote control sensor. The bottom edge is equipped with another speaker system, creating a dual stereo speaker setup. Adjacent to the speaker cluster at the bottom is the location for the microphone, Type-C charging port, and SIM card slot. It's quite unfortunate that the device still lacks a 3.5mm headphone jack.

The Redmi K50 Extreme Edition's 1.5K resolution display optimizes the user experience

The reason why the Redmi K50 Extreme Edition features a rather unusual 1.5K resolution screen is because Xiaomi conducted research and found that the frequency of users opting for a 2K screen is not high. Especially on devices with small battery capacities, reducing the screen resolution is a solution that many people choose to ensure longer battery life.

Therefore, the choice of 1.5K screen resolution is to balance battery life and clarity. This is also a better way to balance the display capabilities of screens at the current time.

If you think this upgrade from the company is just about raising the resolution from Full HD to Full HD+ like some other manufacturers, you're mistaken! The screen of the Redmi K50 Extreme Edition is customized to sit between the two popular resolution options of Full HD and 2K, or simply put, the device has a screen that meets the 1.5K standard.

The device's screen is not a product from an external manufacturer supplied to Redmi, but Redmi has directly participated in the design, customization, trial production, and mass production expansion process. This is a result of their research with screen suppliers to ensure that each screen is customized according to the company's standard process. This is considered a core technology of Redmi.

Igeek Phone has compared and found that the pixel aperture ratio of the Redmi K50 Extreme Edition (left) is significantly larger than that of the K50 Gaming Edition (right), ensuring the efficiency of light transmission and also benefiting the brightness of the Redmi K50 Extreme Edition's screen. This website also evaluates that the screen of the Redmi K50 Extreme Edition is sharper, providing a more impressive daily usage experience compared to the K50 Gaming Edition.

The Redmi K50 Extreme Edition features powerful hardware with the Snapdragon 8+ Gen 1 chip

The Snapdragon 8+ Gen 1 processor, manufactured by TSMC, includes eight cores: 1 large Cortex-X2 core clocked at 3.19 GHz, 3 Cortex-A710 cores clocked at 2.75 GHz, and 4 Cortex-A510 cores clocked at 2.0 GHz.
