Xiaomi 17 Ultra Launch – Slim, Stunning, and Built for Low‑Light Legends
Xiaomi has officially confirmed that the Xiaomi 17 Ultra will launch in China on December 25, 2025 at 7PM local time. The event will take place during the Xiaomi x Leica Imaging Strategic Cooperation Upgrade showcase, which will highlight the brand’s next step in smartphone imaging. As a result, fans are already excited to see what the new Ultra can deliver.
Slimmest Ultra Flagship Yet
With a thickness of just 8.29mm, the Xiaomi 17 Ultra turns out to be the company’s thinnest Ultra model ever. Moreover, it keeps the signature style of its predecessors, featuring a large circular Leica‑branded camera island on the back. Because of its balanced design and flat screen, the new Ultra looks sleek and premium.
Shimmering Starry Sky Green Design
In addition to black and white variants, Xiaomi revealed a bold Starry Sky Green colour. This special finish includes ore particles that sparkle like stars under light, giving the phone a vivid, eye‑catching look. Furthermore, the handset has segmented circular volume buttons and a smooth 2D flat display, which together create a refined and comfortable hold.
Leica Cameras and Low‑Light Boost
The Xiaomi 17 Ultra will feature a triple‑camera setup, led by a 50MP primary 1‑inch OmniVision OV50X sensor. Alongside, it includes a 200MP Leica periscope telephoto lens for stronger zoom quality and clear night shots. Plus, Xiaomi teased a new simultaneous telephoto optical system, promising a huge upgrade in low‑light photography performance.
Designed for Light, Speed, and Clarity
In sample photos shared online, the sensor captured crisp results at ISO 64, with a 1/50s shutter speed and f/1.67 aperture. Hence, image details looked bright even in dim settings. Clearly, Xiaomi’s close work with Leica continues to push its Ultra series toward professional‑level imaging.
The Flagship That Redefines Slim and Sharp
Considering its thinner frame, new colour, and advanced camera system, the Xiaomi 17 Ultra stands out as the most refined Ultra device so far. Whether for style, photography, or technical innovation, Xiaomi aims to make this flagship its most impressive release yet.
