REDMI K80 Pro: Powerful Flagship with Stunning Display and Fast Charging

Lu Weibing once explained the reason for the price increase of Xiaomi, stating that “3999 yuan ($552) is a challenge for us.” However, even with such tight control to maintain at 3999 yuan, sales have continued to soar. In less than two months, more than a million units of the Xiaomi Mi 15 series were sold, creating a new milestone for Xiaomi’s high-end phones, including the Redmi K80 Pro.

While prices have steadily risen from the Xiaomi 13 to the Xiaomi 15, demand has remained strong, proving that Xiaomi’s move toward premium devices has been successful. However, the 4,000-yuan price range now needed a new product to fill the gap. Instead of launching a new line, Xiaomi turned to the popular Redmi K series. In celebration of its 10th anniversary, Redmi was rebranded as REDMI, emphasizing strength and boldness.

Positioning in the higher series, K series will seek dominance in the flagship market, with the star being the REDMI K80 Pro. Powered by the powerful Snapdragon 8 Extreme processor, Rage Engine 4.0, and a newly upgraded 2K display, this model guarantees the best user experience. With its 6000mAh battery, 120W fast charging, IP69 dust and water resistance, and top-notch image shooting capability, this will be the ultimate flagship within 4,000 yuan.

Design

So far, the REDMI K80 Pro has a very fresh and bold design from an aesthetic point of view; hence, the double-piece splicing back cover and firm metal frame create a premium sensation. The model we are reviewing is the Snow Rock White version, which enjoys a Light Dance Duplex material. The back panel in this device is more in light blue color, especially from light to sky blue, with intricate snowflake-like patterns. It looks extremely youthful and stylish.

It comes with only 1.9mm of the screen border for its display, achieved thanks to advanced in-screen wiring technology, and protected with Xiaomi Dragon Crystal Glass 2.0. That 2K display from Huaxing M9 supports 12-bit color and is capable of output up to 3200 nits of peak brightness-clear view even under a really sunny day. Support is extended to full-brightness DC dimming and round polarization technology to add safety against flicker damage while preventing retinal damage of vision.

Furthermore, the K80 Pro includes an integrated Storm Eye lens module, representing its leap in innovation. The metal frame adds to its premium feel, and the phone is fitted with IP69 dust and water resistance. Inside the package, there is also a 120W fast-charging kit, showing that the brand does not save on top performance and experience.

Performance

The Redmi K80 Pro is powered by the flagship Snapdragon 8 Extreme Edition, built on TSMC’s second-generation 3nm process, delivering exceptional performance. The chip uses an Oryon architecture, with two ultra-high frequency 4.32GHz cores and six 3.53GHz large cores, offering a significant boost in speed. The Adreno 830 GPU further enhances gaming performance with a 40% improvement, making it well-equipped to handle even the most demanding games.

Equipped with Rage Engine 4.0 and a dedicated D1 game graphics chip, the K80 Pro has an excellent performance in games: it supports game interpolation and super resolution, so the gameplay is smoother. Below is a summary of performance across various tests and games.

Game Testing:

Temperature Control: The 5400mm² 3D dual-loop ice-sealed cooling system helps to control temperatures and ensure that the device will keep cool even under the most severe gaming sessions. Light-intensity games like Honor of Kings or hardcore-consuming games such as Genshin Impact and Honkai Impact 3rd are no problem, as the K80 Pro will be able to sustain it smoothly at the highest setting. Frame rate interpolation further boosts performance, pushing frame rates in demanding games up to 120FPS.

Overall, the Redmi K80 Pro stands out as a true powerhouse with top-tier gaming performance and excellent thermal management.

Camera

The camera of the Redmi K80 Pro is one of its standout features, offering a versatile combination of lenses that deliver excellent image quality across various scenarios. Here’s a breakdown of its camera system and performance:

Main Camera:

The 50MP Light Hunter 800 sensor is at the core of the K80 Pro’s imaging capabilities. This large 1/1.55-inch CMOS sensor with 2.0μm pixels ensures excellent light capture and detail, especially in low-light conditions. The sensor also features OIS, which reduces shake and enhances clarity. Having been used in several Xiaomi models, including the Civi and some earlier K series phones, it has been fine-tuned for polished, realistic photography. The main camera produces natural “Lei flavor” images, a signature of Xiaomi’s image processing—delivering true-to-life colors suitable for everyday shooting.

The 50MP Samsung JN5 telephoto lens uses a 1/2.76-inch CMOS sensor with 0.64μm pixels. It supports 2X, 2.5X, and 5X optical zoom, with up to 60X digital zoom. Borrowing its optical design from the Xiaomi Mi 15, the high-quality floating telephoto system enables sharp and detailed images even at higher zoom levels. It performs particularly well at 2.5X and 5X zoom, delivering impressive detail with minimal distortion.

Ultra-Wide Angle Lens:

The 32MP ultra-wide-angle lens provides a broader field of view, perfect for landscape shots or group photos. The lens excels in edge control, minimizing distortion and delivering well-balanced wide-angle shots with accurate detail across the frame.

Imaging Performance:

Overall, the Redmi K80 Pro delivers a powerful and versatile photography experience. Its combination of the Light Hunter 800, Samsung JN5 telephoto, and 32MP ultra-wide-angle lenses provides flexibility and high-quality results, positioning it as a strong contender in mobile photography within its price range.

Battery

In summary, the REDMI K80 Pro is powered by a large 6000mAh Jinshajiang battery, a significant increase from its predecessor, the K70 Pro, which had a 1000mAh smaller battery. Combined with the energy efficiency of the Snapdragon 8 Extreme Edition, this results in a notable extension of battery life, allowing for more hours of use on a single charge.

Charge Capability:

The device supports 120W wired and 50W wireless fast charging, ensuring rapid power restoration. It also integrates Xiaomi’s custom-developed Surge P3 charging chip and G1 power management chip, both of which help optimize the charging process and enhance battery management.
