The 2025 Spring Flagship Showdown: An In-Depth Comparison of the OPPO Find X8 Ultra and Xiaomi 15 Ultra

Spring 2025 brings two highly anticipated flagship smartphones to the market: the OPPO Find X8 Ultra and the Xiaomi 15 Ultra. Both phones heavily emphasize "Night God"-level imaging capabilities, promising to redefine mobile night photography through hardware innovations and algorithmic optimizations, captivating photography enthusiasts. Their striking similarities in imaging systems and numerous other specifications make choosing between them a difficult task for consumers. This article provides a detailed comparison of their specifications to help inform your purchase decision.

Imaging Systems: Distinct Styles, Compelling Capabilities

The imaging system is the core battleground for the OPPO Find X8 Ultra and Xiaomi 15 Ultra. Both utilize extremely large main sensors, but their implementations differ.

The OPPO Find X8 Ultra features a 1-inch Sony IMX900 sensor (50MP, f/1.8 aperture), leveraging the advantages of a large sensor for significantly increased light intake. It incorporates a dual periscope lens combination: a Sony IMX906 (3x optical zoom) and an IMX882 (6x optical zoom), covering the 3x-6x focal length range to offer greater creative freedom. Additionally, a 50MP Sony IMX882 sensor is included, with hardware optimizations to suppress distortion and support high-specification video recording. Notably, the Find X8 Ultra adds a 135mm focal length IMX882 lens, paired with a Hasselblad multispectral sensor and Hasselblad color tuning along with AI algorithms for white balance and dynamic range optimization, ultimately achieving its advertised "Night God" night photography performance.

The Xiaomi 15 Ultra is equally impressive. Its main camera also boasts a 1-inch sensor and claims to have the "industry's largest aperture" (f/1.63), further maximizing light intake. It features a 200MP periscope telephoto lens (100mm focal length, f/2.6 aperture), supporting up to 28x lossless zoom and covering a full focal length range from 14mm to 400mm. A 14mm ultra-wide-angle lens with floating focus technology is also included, enhancing compatibility with both close-up and distant subjects. The Xiaomi 15 Ultra's lens combination is equally powerful. On the optical front, it utilizes Leica's co-developed "Ultra-Pure Optical System," using lens coatings and structural optimizations to significantly reduce ghosting and flare, enhancing night scene clarity.

In summary, the OPPO Find X8 Ultra focuses on mid-to-long telephoto ranges with its dual periscope lenses, while the Xiaomi 15 Ultra achieves broader coverage through its full focal range and ultra-high-resolution telephoto lens. They represent two distinct imaging styles. In terms of color and optical performance, the Hasselblad multispectral sensor emphasizes accurate color reproduction, while the Leica Ultra-Pure system prioritizes optical purity a noticeable difference.

Core Specifications: Flagship-Level Performance, Minor Differences

Beyond the imaging systems, the differences between the two phones in other core specifications are minimal. Both are powered by the Snapdragon 8 Gen 3 processor, easily satisfying the needs of gamers. Battery capacity is comparable, with both phones boasting around 6000mAh batteries and supporting high-speed wired and wireless charging, eliminating range anxiety in daily use.

Display: Flat vs. Curved

The screen choices differ slightly. The OPPO Find X8 Ultra features a 6.82-inch 2K flat display utilizing LIPO ultra-narrow packaging technology, achieving the narrowest bezels among contemporary Ultra flagship phones from domestic brands. The Xiaomi 15 Ultra, conversely, uses a 6.73-inch 2K slightly curved display (LTPO AMOLED) with a 1-120Hz adaptive refresh rate for a smoother visual experience. Both phones feature ultrasonic fingerprint unlocking and high-frequency PWM dimming, ensuring top-tier screen quality. However, due to different screen suppliers, the final display effect requires hands-on experience to judge.

Features and System: Feature Parity, Distinct UI

In terms of features, the two phones are almost identical, both supporting full-function NFC, infrared remote control, dual speakers, X-axis linear motors, and IP68/IP69 dust and water resistance. System-wise, the OPPO Find X8 Ultra runs ColorOS 15, while the Xiaomi 15 Ultra runs MIUI 15 (or a potential successor); both offer different system styles and functionalities, demanding a user preference-based choice.

Design and Price: Different Aesthetics, Potential Price Increase

The design language is distinct. The OPPO Find X8 Ultra adheres to a flat-screen design with a metal frame and a centrally positioned large circular camera module, with excellent camera bump control and an expected thickness below 9mm. The Xiaomi 15 Ultra continues the slightly curved screen design, featuring a glass and vegan leather back cover, resulting in a heavier overall feel.

Regarding price, both phones are expected to see a price increase of around 200 Yuan over their predecessors; the official prices will be announced later.

Release Date: Xiaomi First, OPPO to Follow

The Xiaomi 15 Ultra will be released this month, followed by the OPPO Find X8 Ultra in March.

Summary: Which One to Choose?

The OPPO Find X8 Ultra and Xiaomi 15 Ultra are among the most anticipated flagship phones of Spring 2025, each excelling in imaging systems, displays, and system experiences. If you prioritize a flat screen, Hasselblad color science, and a relatively slim profile, the OPPO Find X8 Ultra is a better choice. If you prefer a curved screen, full focal length range coverage, and the pure imaging of the Leica optical system, the Xiaomi 15 Ultra might be more suitable. The final decision depends on your personal preferences regarding smartphone functions and design aesthetics. Ultimately, hands-on experience is crucial before making the best choice for you.
