K80

1. Core configuration: The performance cornerstone of the Snapdragon 8 Gen3

As the benchmark model in the mid-market in 2024, the Redmi K80 is equipped with the third-generation Snapdragon 8 processor of TSMC's 4nm process, using 1 × Cortex-X4 (3.3GHz) + 5 × Cortex-A720 (3.0GHz) + 2 × Cortex-A520 (2.0GHz) architecture, AntuTu breaks through the 2.10 million. With LPDDR5X memory and UFS 4.0 flash memory, the daily application startup speed is increased by 20%, and the multi-task switching is smooth without cards. The average frame rate of the measured "Yuan Shen" Sumi City scene is 58.7 frames, the fuselage temperature is controlled at 39.2 ° C, and the energy efficiency ratio is better than that of competitors at the same price.

Heat dissipation and battery life : 4500mm ² graphene ice-sealed cooling system covers the core area, and the frame rate fluctuation is less than 3% after 2 hours of continuous game. 6550mAh silicon carbon negative electrode battery supports 90W fast charging, DOU battery life is 1.9 days, heavy use (4 hours of game + 3 hours of video) The remaining power is 22%, and 30% power can be restored after 5 minutes of charging.

2. Screen and interaction: 2K delicate display and ultrasonic fingerprint

6.67 inch 2K LTPS OLED straight screen (3200 × 1440 resolution) adopts M9 luminous material, peak brightness 3200nit, support 120Hz refresh rate and 2560Hz instantaneous touch sampling rate, touch delay is as low as 4.1m. "Aoyama Eye Protection 2.0" technology implementation full brightness DC dimming + circularly polarized light, through Rheinland triple certification, visual health friendliness up to S ++ level, night reading comfort is 35% higher than traditional PWM dimming.

Ultrasonic fingerprint and stereo interaction : The world's first 3D ultrasonic fingerprint recognition, wet hand unlock success rate of 99%, speed increased by 200% compared to optical fingerprints, support 0.18 seconds speed unlock and live detection. Ultra-wideband X-axis motor (0809 specification) starts and stops 40% faster, "Game for Peace" shooting shock feedback is accurate; symmetrical stereo double Yang (Upper Goertek 1014D + lower 1115F) achieves a large amplitude of 0.7mm, low frequency dive to 85Hz, and external amplifier sound quality is comparable to flagship.

3. Imaging system: Daily creativity of light and shadow hunter 800

Rear 50 million pixel light and shadow hunter 800 main camera (1/1.55-inch outsole, OIS optical image stabilization, f/1.6 aperture) + 8 million pixel ultra-wide-angle lens, supports AI magic elimination and generative ultra-clear algorithms, the dynamic range of the daytime scene is 12.8EV, and the noise control of the night scene is better than that of competitors at the same price. The front 20 million pixel lens supports AI beauty and background blur, and the clarity of WeChat video calls is increased by 20%, but the background blur transition of portrait shooting is slightly stiff.

AI image upgrade : LivePhoto 2.0 increases the frame time by 3 seconds, supports night scene/anti-shake algorithm optimization; Mi clip supports dynamic frame import, and can generate movie frame size with one click. AI generative ultra-clear technology can repair blurred photos, save waste films with one click, and meet daily social sharing needs.

4. Design and quality: mid-range presentation of flagship texture

The fuselage adopts aviation-grade aluminum alloy middle frame + glass fiber backplane, providing four color schemes such as basalt black and snow rock white. The weight is 205g and the thickness is 8.12mm. It is comfortable to hold in one hand and has outstanding texture. IP68/IP69 dustproof and waterproof supports 1.5 meters water depth immersion for 30 minutes. It has passed the military-grade 1.5 meters six-sided drop test, and its durability exceeds that of the same price model. The metal camera Deco adopts a storm eye design and is matched with the aviation aluminum lens ring precisely cut by diamond knives. It has both recognition and aesthetics.

5. System and ecology: The full-scene experience of Surging OS 2.0

Runs Surging OS 2.0 system, supports multi-device interconnection (mobile phones, tablets, cars seamlessly cooperate), cross-screen clipboard and split-screen multitasking. In terms of communication, equipped with Surging T1S signal enhancement chip, supports 5G-A, WiFi 7 and "kilometer-level no Netcom" voice calls, and the 5G signal switching delay in high-speed rail scenes is reduced to less than 25ms.

AI interaction upgrade : Super Xiao Ai supports multi-modal interaction, can perceive screen content through the camera, and realize complex operations such as "help you find" and "help you execute"; AI writing, voice recognition, and translation functions cover the whole world, and the real-time transcription accuracy of conference scenes reaches 97%.
