Redmi has officially unveiled the K80 Ultra in China, solidifying its position at the forefront of high-performance smartphones. Launched alongside the Mix Flip 2, the K80 Ultra introduces cutting-edge hardware, AI enhancements, advanced cooling systems, and top-tier display technology, making it the most powerful model in the K-series to date.
The Redmi K80 Ultra boasts a 6.83-inch 1.5K flat OLED display that delivers fluid visuals with its 144Hz refresh rate and ultra-responsive 480Hz touch sampling rate. The screen features M9 luminescent material, reaching a peak brightness of 3200 nits, which ensures vibrant visibility even under direct sunlight.
Xiaomi hasn’t cut corners on display quality—supporting Dolby Vision, HDR10+, full-brightness DC dimming, and 2560Hz PWM dimming for reduced eye strain. The panel is protected by Xiaomi’s Shield Glass and includes circular polarizers and TÜV low blue light certifications, alongside China's S++ visual comfort rating, marking it as one of the best smartphone displays in the segment.
At its core, the K80 Ultra is powered by MediaTek’s flagship 3nm Dimensity 9400+ chipset, paired with the Immortalis-G925 GPU. The phone has reportedly scored over 3.24 million on AnTuTu, setting a new benchmark for MediaTek-powered devices.
Further enhancing the performance is Xiaomi’s D2 AI Display Chip, which brings AI frame interpolation, real-time resolution upscaling, and gaming enhancements. This AI-powered chipset ensures smoother animations, optimized visuals, and a more immersive experience whether you’re gaming or watching HDR content.
To maintain peak performance, the K80 Ultra is equipped with a massive 6500mm² 3D IceLoop vapor chamber. The two-tier elevated design maximizes thermal dissipation and is supported by Redmi’s fourth-gen Fury Engine, which intelligently manages thermals and performance in real time.
The phone runs on Xiaomi’s HyperOS 2, based on Android 15, offering system-wide improvements in fluidity, battery optimization, and AI features tailored specifically for the K80 Ultra's hardware capabilities.

Charging is equally impressive, thanks to 100W wired fast charging and Bypass Charging Plus, which reduces heat during charging—especially useful while gaming or streaming. The combination ensures quick top-ups without compromising battery health.
