Xiaomi 17 Ultra: Leica Coating Revolutionizes Photography
Xiaomi 17 Ultra: Leica’s Revolutionary Coating Redefines Mobile Photography
Get ready for a game-changer! The Xiaomi 17 Ultra is arriving this month, poised to revolutionize mobile photography. Leaks from insiders like Smart Pikachu suggest Xiaomi is launching the Ultra ahead of schedule in China, armed with a revolutionary Leica coating. This tech promises crystal-clear images, eliminating chromatic aberration and unwanted reflections. If you thought the Xiaomi 15 Ultra set a high bar, prepare to be amazed. The Xiaomi 17 Ultra is shaping up to be the definitive “photophone” of 2025.
Why Now? The Xiaomi 17 Ultra’s Early Arrival
Xiaomi’s decision to fast-track the Xiaomi 17 Ultra launch is strategic. While the standard Xiaomi 17 and 17 Pro earned praise for their balanced performance and price in September, the Ultra’s early debut aims to steal the spotlight from rivals like the Samsung Galaxy S25 Ultra and iPhone 17 Pro Max. Reports indicate a late December launch in China, with model numbers like 25128PNA1C and 2512BPNDAC. A global release might follow in March 2026 at the Mobile World Congress, but the anticipation is already building.
The timing is perfect for capitalizing on holiday shopping and end-of-year sales. With an estimated starting price of around 6,000 yuan (800-900 euros), this flagship phone remains relatively accessible.
The Leica PureCoat Revolution: A Quantum Leap in Mobile Optics
The heart of the Xiaomi 17 Ultra‘s innovation lies in its exclusive Leica coating, a nanotech layer applied to the lenses. Leaks suggest this “Leica PureCoat” eliminates chromatic aberration (those annoying color fringes around objects) and reduces reflections by a staggering 50%! This technology also boosts light transmission by 20% compared to previous generations, delivering high-definition images with unparalleled color fidelity.

Capturing Perfection: How Leica PureCoat Works
Imagine capturing a vibrant sunset without purple fringing or shooting a stunning night portrait without distracting lens flares. Leica, Xiaomi’s partner since the 12S series in 2022, has refined this multi-layered coating (up to 7P in Summilux lenses) to mimic professional camera performance. This coating essentially makes the phone “understand” light, correcting ghosting and glare in real-time. It’s a dream come true for content creators and astrophotography enthusiasts. For comparison, you can check the advancements of previous generations on Xiaomi 15 Ultra.
- Eliminates Chromatic Aberration: Say goodbye to distracting color fringes.
- Reduces Reflections: Capture cleaner, clearer images even in challenging lighting.
- Boosts Light Transmission: Enjoy brighter, more vibrant photos.
- Corrects Ghosting and Glare: Achieve pristine image quality in any situation.
This isn’t just marketing hype. The PureCoat addresses real-world problems. Reflections accounted for roughly 1% of complaints about the Xiaomi 15 Ultra, according to some reviews. With PureCoat, Xiaomi aims to eliminate that issue, solidifying the 17 Ultra as the king of pure, unadulterated photography.
