Xiaomi 15 Ultra : A Premium Flagship with Top Performance and Imaging

On February 27, 2025, Xiaomi officially launched the highly anticipated Xiaomi 15 Ultra. With its exceptional performance and powerful imaging system, the phone quickly caught the attention of numerous consumers upon release.

Design: A Blend of Classic and Innovation
The Xiaomi 15 Ultra continues the circular lens design from the previous generation. The periscope telephoto lens is cleverly placed at the top right corner of the circular lens, with three cameras arranged in a row below it. This unique layout not only offers high recognition but also showcases Xiaomi’s innovative design spirit. The phone comes in four colors: classic black, silver, white, and a special pine green, offering more personalized options for consumers. The white version, for example, features a unique “cloud-pattern texture” on the back panel, providing a delicate feel and a lighter visual appearance, as if the softness and intricacy of clouds were embedded in the phone itself.

Display: A New Visual Experience
The Xiaomi 15 Ultra is equipped with a 6.73-inch full-depth curved display with an ultra-high resolution of 3200×1440 and a pixel density of 522ppi, presenting users with incredibly clear and detailed visuals. The screen supports an adaptive refresh rate of 1 - 120Hz, automatically adjusting to different usage scenarios to ensure smooth visuals while effectively reducing power consumption. With a peak brightness of 3200 nits, the display remains clear even under strong sunlight. Additionally, the screen features 100% P3 wide color gamut, always-on display, professional color accuracy, Xiaomi multi-screen color matching, ultra-dynamic display, and ambient color temperature sensing, all of which have been certified by three eye-care standards, providing users with a comfortable and healthy visual experience.

Imaging System: A Pocket-sized "Big Three"
The Xiaomi 15 Ultra collaborates with Leica to create a new Leica Super Pure Optical System, codenamed “Night God,” which can be considered a pocket-sized “big three.” The rear Leica quad-camera system covers the entire focal length range from 14mm to 400mm, with up to 28x lossless zoom. The 1-inch large main sensor features a 50 MP LYT-900 image sensor, an f/1.63 aperture, and OIS optical stabilization, capturing rich details and excellent image quality. The 14mm f/2.2 ultra-wide-angle lens offers a broader shooting view, perfect for landscape shots. The 70mm f/1.8 floating-focus lens and the 100mm 200MP f/2.6 periscope telephoto lens support up to 200mm / 400mm zoom, making it easy to capture distant scenery or intricate details.
The “Leica Super Pure Optical System” enhances the imaging quality across all focal lengths with new optical components. The lens protection glass features new Leica ultra-low reflection lens glass, greatly improving image quality and reducing ghosting, while enhancing scratch resistance by 82.4%. For video, the phone supports unlimited full-focus 8K video recording and features the first Android ACES LOG video recording format, along with the UIS Super Video Stabilization system for smooth, stable videos.

Performance: Powerful, Smooth, and Unstoppable
The Xiaomi 15 Ultra is powered by the Snapdragon 8 Gen 2 mobile platform, utilizing an advanced 3nm manufacturing process. The CPU has two prime cores with a maximum frequency of 4.32GHz and six performance cores with a maximum frequency of 3.53GHz, paired with the Adreno™ GPU and Qualcomm AI engine. Whether multitasking in daily use, running large games, or processing complex graphics, the phone performs effortlessly. It is equipped with LPDDR5X RAM and UFS 4.0 storage for faster data reading and writing, improving system response time and application load speeds. The phone also includes a “dual-path ring-shaped cooling pump” heat dissipation system that effectively reduces the device’s temperature, ensuring stability during high-performance operation.

Battery Life: Long-lasting and Fast Charging
The Xiaomi 15 Ultra features a 6000mAh Jinshajiang battery with 10% silicon content, offering exceptional battery life that supports a full day of heavy usage. For charging, the phone supports 90W wired fast charging and 80W wireless fast charging, powered by the Surge G2 and P3 chips, enabling users to quickly recharge and reduce battery anxiety. Even with low battery levels, it can quickly restore power in a short period. The overseas version of the Xiaomi 15 Ultra comes with a 5410mAh battery but supports the same 90W wired and 80W wireless fast charging.

Communication: Breaking Limits, Connecting the World
The Xiaomi 15 Ultra features “Xiaomi Star Communication,” supporting 7 km bi-directional calls without a network, ensuring reliable communication in extreme environments. It also includes satellite communication, offering the world’s first direct mobile-to-satellite data connection, with an optional dual-satellite version (Chinese Mobile BeiDou satellite communication), enhancing the phone’s communication capabilities in remote areas or environments with poor signal. Additionally, the phone supports Wi-Fi 7 R2 and 5G-Advanced technologies, delivering ultra-fast internet speeds for seamless web browsing, smooth video watching, and uninterrupted online gaming.

The Xiaomi 15 Ultra’s exceptional design, top-tier display, powerful imaging system, strong performance, long battery life, and outstanding communication capabilities make it a highly competitive flagship phone. Starting at ¥6499, the Xiaomi 15 Ultra is an excellent choice for anyone seeking a phone that delivers a premium experience across all aspects.
