Redmi K40 Gaming Edition with 6.67-inch FHD+ 120Hz AMOLED display, Dimensity 1200, dual magnetic gaming triggers announced

Xiaomi under its Redmi brand just announced the Redmi K40 Gaming Edition, the company’s first gaming smartphone in China. It has a 6.67-inch FHD+ flexible AMOLED screen with 120Hz high refresh rate, 480Hz simultaneous three-fingerprint simultaneous touch sampling rate, 1.8mm trilateral equal width, 2.7mm ultra-narrow chin.

It is powered by 6nm Dimensity 1200 SoC with multi-stacked graphite layers combined with super-large vapor chambers, and new aerospace-grade heat dissipation material with a built-in “white graphene” layer that covers 11540mm², which not only efficiently dissipates heat for the charging chip, but also offers good insulation to reduce its impact on nearby antennas to reduce the temperature by 2°C.

The phone has a magnetic dual-trigger design, allowing users to play games using four fingers, instead of only two. This offers stable and realistic pressing feedback, thanks to its mechanical structure. Compared with the traditional mechanical transmission structure, the magnetic triggers can effectively reduce the wear-out in daily use, with a lifespan of up to 1.5 million taps. The phone has Dolby Atmos and is approved by the JBL synthesis certification system, offering a truly immersive gaming experience.

The phone has a 64MP rear camera, 8MP ultra-wide angle camera and a 2MP telemacro camera. The phone has an X-axis Linear Motor and packs a  5,065mAh large battery with 67W fast charging that can charge the phone up to 100% in just 42 minutes. It features  RGB lighting and gaming details and also adopts a low-key and restrained overall appearance.
