Introduction: Can the Redmi K80 Supreme Edition Reign Supreme as the "King of Cost-effectiveness" in 2025?

Amidst a mobile phone market stagnating in incremental innovation, the Redmi K80 Supreme Edition returns with a formidable set of "king-sized specifications" — an all-big-core processor, a 7500mAh battery, 3D ultrasonic fingerprint recognition, and a metal frame. Can this model, designated by Redmi as a "performance flagship," set a "new benchmark" for mid-range phones? Let's dissect it step by step.

I. Performance Powerhouse: Dimensity 9400+ All-big-core, Benchmark Scores Surpass 3 Million

The Redmi K80 Supreme Edition's core configuration is a veritable "performance beast."

Dimensity 9400+ Processor: Boasting an all-big-core architecture comprising 1×Cortex-X925 (3.7GHz) + 3×X4 (3.3GHz) + 4×A720 (2.4GHz), it decisively sheds the performance-limiting small cores. AnTuTu benchmark scores have soared past the 3 million mark, putting it in direct competition with the Snapdragon 8 Gen4.

Cooling and Motor: Equipped with the "Turbo Engine 3.0" cooling system, real-world testing while playing "Genshin Impact" for an hour in Sumeru City yields an average frame rate of 59.8 and a temperature of only 43.2°C. The 0916 large-size X-axis linear motor boosts vibration intensity by 30%, providing a more immersive gaming experience.

Competitive Analysis:

The OnePlus Ace 3 Pro, equipped with the Snapdragon 8 Gen3, scores around 2.8 million on AnTuTu, while the Redmi K80 Supreme Edition leads with a score of 3 million.

II. Battery Evolution: 7500mAh + 120W Fast Charging, Say Goodbye to Battery Anxiety

7500mAh Silicon-carbon Anode Battery: A 36% increase over the K70 Supreme Edition, offering up to 58 hours of heavy usage. Real-world testing demonstrates no strain for 14 hours of TikTok browsing or 7 hours of "Honor of Kings" gameplay.

120W Wired Fast Charging: Reaches 50% in just 12 minutes and a full charge in 25 minutes. Despite the absence of wireless charging, the "charge once every two days" battery life is ample for daily use.

Industry Ramifications:

The introduction of the 7500mAh battery may spark a "battery capacity arms race" in the mid-range phone market.

III. Screen Spectacle: 1.5K Straight Screen + 3D Ultrasonic Fingerprint, 3x Faster Unlock

1.5K OLED Straight Screen: A 6.78-inch display with a 144Hz adaptive refresh rate, 2160Hz PWM dimming, and a peak brightness of 2600 nits. Real-world testing confirms crisp visuals even under direct sunlight.

3D Ultrasonic Fingerprint: Unlock speed of 0.15 seconds, with a 300% increase in recognition accuracy for wet or oily hands. Compared to short-focus fingerprint recognition, the unlock experience represents a "qualitative leap".

IV. Design Elegance: Metal Frame + IP68, Brimming with Texture

Metal Frame + AG Glass Back Cover: Weighing 205g and measuring 7.45mm thick, it offers a sleek and comfortable grip.

IP68 Dust and Water Resistance: Capable of withstanding immersion in 2 meters of water for 30 minutes without issues, providing reassurance for outdoor use.

V. Pricing Strategy: Starting at 2599 Yuan? The "Cost-effectiveness Champion"

12GB+256GB Version: Expected to retail at 2599 yuan (same as the K70 Supreme Edition), with potential subsidies bringing it down to 2400 yuan.

Competitive Comparison:

Models with similar specifications (e.g., OPPO Find X8S) are priced above 4000 yuan, underscoring the Redmi K80 Supreme Edition's significant price advantage.

Market Outlook:

The Redmi K80 Supreme Edition sits in the 2500-3000 yuan price bracket, directly targeting competitors like the OnePlus Ace 3 Pro and iQOO Neo10. With sufficient inventory, it is poised to become a "blockbuster" hit in the second half of 2025.

Conclusion: Redmi K80 Supreme Edition, the "Game Changer" for Mid-range Phones

From its all-big-core processor to the 7500mAh battery, from 3D ultrasonic fingerprint recognition to the metal frame, the Redmi K80 Supreme Edition is redefining the standard for mid-range flagships with "hardcore technology." Facing stiff competition, can Redmi make a comeback with its "king-sized specifications" and "cost-effectiveness strategy"? Only time will tell.
