Official Statement

What does Xiaomi say about the product?

A summary of Xiaomi's official product description.

Official Xiaomi source

Xiaomi positions the 15 Ultra as its uncontested photography flagship, built around Leica optics.

Announced and released on February 27, 2025, the Xiaomi 15 Ultra pairs a 1-inch f/1.6 main sensor with a 200MP periscope telephoto and a second 50MP telephoto, both carrying Leica-branded optics, alongside a 6.73-inch 3200-nit display and 90W wired charging.

Review β€” 4.6 / 5
β€œOne of our favorite camera phones, and it may emerge as the uncontested number one for photography this year.”

GSMArena rates the Leica-branded dual telephoto system, the bright Dolby Vision display and the camera-inspired design highly, while noting the phone runs warm under sustained load, lacks an IPX9 rating and ships without an in-box charger.

Editorial Analysis

Strengths and points to consider

Compiled by the Kacbu editorial team from spec sheets, independent press reviews and reported user feedback.

Strengths based on the specs
One of the best cameraphones available, with a genuine chance at being the top choice for photography in its year.
Bright, high-nit display with Dolby Vision support.
Classic camera-inspired design that stands out from typical slab phones.
Dual telephoto lenses (3x and 4.3x) cover a wider useful zoom range than a single lens.
90W wired and 80W wireless charging are both genuinely fast.
1-inch main sensor with f/1.6 aperture gathers significantly more light than typical flagship sensors.
Things to consider
Runs warmer than rivals when pushed hard for extended periods.
No IPX9 rating, which puts it behind some Chinese rivals on paper.
No charger included in the box despite the fast charging capability.
Global battery capacity (5410 mAh) is notably smaller than the China variant (6000 mAh).
Only four years of major OS updates promised, shorter than several rivals.

FAQ

The most common questions about this product

What the numbers on the spec sheet actually mean in day-to-day use.

Should you buy the Xiaomi 15 Ultra?
The Kacbu decision box currently says WAIT for the Xiaomi 15 Ultra: either the model has been on the market long enough that a successor may be near, or owner data is weak. The reasons are in the decision box at the top of this page.
Is the 200MP telephoto actually useful, or just a marketing number?
The high resolution mainly buys crop headroom β€” past the native 4.3x optical zoom you can push in digitally and the 200MP sensor still holds real detail. Paired with the second 3x telephoto, you get a much more usable zoom range than phones with a single telephoto lens.
Is it too heavy for daily one-handed use?
At 226 g it's on the heavier side for a 6.73-inch phone, especially with the leather-back variant's slightly thicker profile. It's manageable but noticeable compared to lighter flagships like the Pixel 10 Pro.
Does the smaller global battery (5410 mAh vs 6000 mAh in China) hurt battery life?
It's a real difference, but 5410 mAh with efficient software still comfortably covers a full day of typical use. If all-day battery under heavy camera use is your top priority, know you're not getting the China unit's larger cell.
