Redmi Turbo 4: A Trendy, Powerful Compact Flagship Designed for Young People, Redefining the 2025 Smartphone Standard

Launching at the beginning of 2025, the Redmi Turbo 4 makes a powerful entrance as the year's first major new phone, setting the trend for the 2025 smartphone market. This trendy, powerful compact flagship not only debuts with the Dimensity 8400-Ultra flagship chip but also offers a stylish design, a massive battery, and comprehensive protection, providing users with an unprecedented experience and redefining the standard for performance phones in the $2000 price range. The Turbo 4 is not merely a performance upgrade; it's Redmi's precise understanding and perfect response to the needs of young users. It comprehensively advances in performance, appearance, battery life, and protection, creating an exclusive flagship experience for the younger generation.

I. Design: A Blend of Trend and Texture

The Redmi Turbo 4 achieves a qualitative leap in design, addressing the shortcomings in texture of its predecessor, the Turbo 3. It adopts a new trendy dual-tone textured design. The overall lines of the phone are clean and simple, more minimalist and fashionable, and more modern compared to its predecessor. The 2.5D double-sided glass body with a 2.5D micro-curved frame provides a smooth, natural transition and enhances the grip.

The back of the phone uses AG frosted glass, providing a delicate touch and a premium feel. The diamond-shaped area on the right side of the back uses nano-lithography to precisely etch 80,000 orderly arranged diamond-shaped matrices, forming a regular, simple texture that significantly enhances visual layering and highlights Redmi's meticulous attention to detail. A slender waistline runs across the back of the phone, creating a dynamic design language that conveys a sense of poised energy and showcases the Turbo 4's extraordinary temperament.

The iconic dual-ring camera Deco has evolved again, incorporating a dual-ring light design to further enhance the appearance's technological feel and recognizability. Users can customize the color of the dual-ring light, enabling personalized cool effects such as incoming call flashes and music flashes, providing a more entertaining visual experience.

The front features a 6.67-inch Huaxing Optoelectronics OLED screen with a 1.5K resolution. Using a new light-emitting material, it boasts a peak brightness of 3200 nits, ensuring clear display even in bright sunlight. The screen also incorporates Xiaomi's QingShan eye protection solution, using DC dimming + 1920Hz high-frequency PWM dimming to effectively reduce blue light hazards and comprehensively protect users' eye health, meeting users' eye protection needs in different scenarios.

The power button and volume buttons are located on the right side of the phone for easy one-handed operation. Independent speaker openings are located at the top and bottom of the phone, with a 1014+1115 symmetrical sound field creating a stronger stereo effect and enhancing immersive gaming and entertainment experiences. Pressure relief valves are also located at the top and bottom, providing solid protection for the phone's IP66, IP68, and IP69 full-level waterproof performance.

II. Performance: Dimensity 8400-Ultra Flagship Chip, a Wave of Power

The Redmi Turbo 4 is the world's first phone to feature the Dimensity 8400-Ultra mobile platform. This chip uses TSMC's second-generation 4nm process and a full-large-core design, achieving a comprehensive breakthrough in performance and energy efficiency. The 8Cortex-A725 full-large-core architecture includes one 3.25GHz ultra-large core, three 3.0GHz large cores, and four 2.1GHz large cores. The large cores have higher computing power and support out-of-order execution, significantly improving multi-threading and parallel computing performance while reducing power consumption.

Compared to the previous generation, the Dimensity 8400-Ultra's CPU performance is improved by 12%, and power consumption is reduced by 35%. By significantly upgrading the cache size (L2 +100%, L3 +50%, SLC +25%), it achieves higher operating efficiency and lower memory access latency, ensuring smooth and stable phone operation.

In terms of GPU, the Dimensity 8400-Ultra uses the same generation Mali-G720MC7 architecture as the Dimensity 9300 flagship, with a 24% performance increase and a 42% power consumption reduction. It also supports DVS deferred vertex shading technology, further reducing graphics processing power consumption.

Overall, the Dimensity 8400-Ultra achieves a leapfrog upgrade with a 41% performance increase and a 44% power consumption reduction. Especially in high-frequency daily usage scenarios, it demonstrates lower load and heat generation, representing the biggest energy efficiency improvement in the history of the Dimensity 8000 series.

To verify the actual performance of the Redmi Turbo 4, we conducted comprehensive theoretical performance tests and game tests. During testing, we enabled the phone's "Beast Mode" and disabled memory expansion to maximize the phone's performance potential.

Theoretical Performance Tests: Antutu benchmark score is close to 1,763,000; Geekbench 6 single-core performance is 1642 points, multi-core performance is 6348 points, with a nearly 18.2% year-on-year increase in multi-core capability; GFXBench six 1080P high-level test results show a GPU performance improvement of approximately 20%; Androbench sequential read speed is 3865 MB/s, and sequential write speed is 1769 MB/s, meeting UFS4.0 standards.

Game Tests: We selected three mainstream mobile games, "Honor of Kings," "Genshin Impact," and "Honkai: Star Rail," for testing. In an indoor office environment at 24 degrees Celsius, we conducted tests in frame rate priority mode and recorded the frame rate, power consumption, energy efficiency ratio, and body temperature during gameplay. The test results showed that the Redmi Turbo 4 exhibited excellent performance and smoothness in all three games, with stable frame rates, low power consumption, and excellent heat control. Particularly in "Honkai: Star Rail," the average frame rate reached 58.7 FPS, with stable frame rate fluctuations, completely conquering this new generation of hardware killer.

III. Charging and Battery Life: 6550mAh Super-Large Capacity Battery, Long-Lasting Battery Life, Powerful Fast Charging

The Redmi Turbo 4 is the first model equipped with a dual boost chip. Using partitioned precise boost technology, it effectively releases battery capacity. In an extremely cold environment of -20C, the actual usable battery capacity is measured to be 100% higher than traditional solutions. The dual boost chip manages different power-consuming components in partitions, intelligently adjusting voltage output to avoid device crashes caused by low temperatures or low battery levels.

It features a built-in 6550mAh Jinshajiang battery, the largest capacity battery in the Redmi and even the Xiaomi series of phones, and is compatible with 90W super-fast charging. Charging tests show that it takes only 43 minutes to charge from 1% to 100%, which is a highly desirable charging speed. Battery life tests show that a full charge can last for nearly 11 hours, easily meeting the user's daily needs.

IV. Imaging System: Sony LYT600 Main Camera, Clearly Capturing Wonderful Moments

The Redmi Turbo 4 has a rear dual-camera module. The main camera uses a Sony LYT600 sensor with a 1/1.953-inch photosensitive unit and an F1.5 large aperture, and supports OIS optical image stabilization. The ultra-wide-angle lens uses an 8-megapixel sensor and features distortion correction.

Sample image test results show that in bright daytime scenes, the Turbo 4's main camera can capture photos with color saturation closer to reality, and the image colors are natural and realistic; in nighttime scenes, turning on night mode can accurately restore light and dark details, the picture is clean, and noise control is excellent; the ultra-wide-angle lens can handle the detail capture of ultra-wide images, and the image quality is sufficient to meet daily shooting needs.

V. Comprehensive Protection: IP66/68/69 Full-Level Protection, Safe and Reliable

The Redmi Turbo 4 supports IP66/68/69 full-level protection, providing stronger water and dust resistance for daily use and outdoor scenarios, adding reliable protection and giving users peace of mind.
