Xiaomi has officially pulled back the curtain on its next flagship camera phone, the Xiaomi 17 Ultra. Following a series of executive teasers, the company has confirmed a Christmas Day launch in China, revealing a device that promises significant refinements in design and a major leap in photographic hardware. The new model aims to redefine expectations for mobile imaging with a partnership-driven approach and cutting-edge sensor technology.
Xiaomi Confirms December 25 Launch with Design Reveal
After a cryptic "tomorrow" post from company president Lu Weibing, Xiaomi has solidified the launch timeline for the Xiaomi 17 Ultra. The smartphone is scheduled for release on December 25, 2025, in China, a notable shift from the typical February launch window of its predecessor. This strategic timing positions the device as a potential premium holiday season offering. Alongside the date announcement, Xiaomi provided the first official look at the phone's design, showcasing a more streamlined and user-friendly form factor that marks a departure from previous Ultra models.
Key Specifications (Confirmed & Rumored)
- Launch Date: December 25, 2025 (China)
- Design: 8.29mm thick (thinnest Ultra), 2D flat display, compact camera module.
- Colors: Black, White, Starry Green (mineral particles), Cool Smoke Purple (rumored).
- Chipset: Snapdragon 8 Elite Gen 5 (expected).
- Main Camera: 1-inch type sensor with LOFIC technology.
- Telephoto Camera: 200MP periscope lens ("optical zoom era").
- Battery: 6,800mAh (rumored).
- Charging: 100W wired fast charging (rumored).
A New, Thinner Design Philosophy for the Ultra Series
One of the most striking announcements is the Xiaomi 17 Ultra's new physical profile. President Lu Weibing has confirmed it will be the thinnest Xiaomi Ultra phone to date, with a body measuring just 8.29mm—an 11.3% reduction compared to the last model. The design features a segmented volume rocker and a wraparound middle frame for improved ergonomics. Perhaps the most significant design change is the adoption of a large-radius 2D flat display, a first for the Ultra series, which traditionally used curved screens. The rear camera module has also been made more compact to prevent it from interfering with grip.

Expanded Color Palette and Premium Finishes
Xiaomi is introducing new color options to complement the classic black and white finishes. A new "Starry Green" variant has been officially announced, which incorporates mineral particles into its finish to create a sparkling, textured effect reminiscent of a night sky. While not yet officially confirmed in the latest materials, a "Cool Smoke Purple" color was also mentioned in earlier reveals, suggesting Xiaomi may be preparing multiple aesthetic choices to cater to different tastes, all while maintaining a premium feel.
Revolutionary Camera System Co-Developed with Leica
The core of the Xiaomi 17 Ultra's upgrade lies in its imaging system, born from a deepened "Strategic Co-creation" partnership with Leica. The slogan "Vivid Nightscapes" hints at a focus on low-light performance. The hardware is headlined by a new 1-inch type main sensor equipped with LOFIC (Lateral Overflow Integration Capacitor) technology. This hardware-level solution is designed to prevent pixel saturation, dramatically improving dynamic range and detail preservation in high-contrast scenes, essentially allowing the camera to see more like the human eye.
The 200MP Periscope Telephoto and Optical Zoom Ambitions
Complementing the main sensor is a groundbreaking 200-megapixel periscope telephoto lens. Xiaomi claims this setup ushers in "the era of optical zoom" for its long-range cameras, suggesting a strong emphasis on lossless zoom capabilities. Early rumors and reports indicate the phone may feature a continuous optical zoom mechanism, which would allow for high-quality shots across a range of focal lengths without switching cameras or relying heavily on digital cropping. This could represent a major competitive advantage in mobile photography.
Performance and Battery Expectations
While full specifications will be confirmed at launch, reliable information points to the Xiaomi 17 Ultra being powered by the latest Snapdragon 8 Elite Gen 5 system-on-chip, ensuring top-tier performance. In a significant boost to endurance, the device is rumored to house a massive 6,800mAh battery, a substantial increase from the 5,410mAh cell in the Xiaomi 15 Ultra. It is also expected to support 100W wired fast charging, offering a slight upgrade from the previous model's 90W capability, which should translate to very quick recharge times.
Positioning in a Crowded Premium Market
The Xiaomi 17 Ultra enters a fiercely competitive segment, going head-to-head with other imminent camera-centric flagships like the Vivo X300 Ultra and Oppo Find X9 Ultra. Its success will hinge on how well its new 1-inch LOFIC sensor and 200MP telephoto system perform in real-world conditions against the computational photography and lens innovations of its rivals. The device's thinner, flat-screen design also represents a strategic choice to appeal to users who prioritize ergonomics and a modern aesthetic alongside photographic prowess.
Global Release Timeline Awaited
As of now, Xiaomi has only announced the China release date for the Xiaomi 17 Ultra. Historically, the global launch of the Xiaomi 15 Ultra followed roughly a month after its Chinese debut. If the company maintains a similar schedule, international audiences could expect to see the Xiaomi 17 Ultra on global markets sometime in January 2026, making it one of the first next-generation flagship devices available worldwide in the new year.
