The Xiaomi 17 Ultra has officially entered the arena as an early contender for the best camera phone of 2026, boasting a photographic toolkit that rivals the finest devices on the market. While the collaboration with Leica has produced a camera system of unquestionable quality, potential buyers must weigh this against a surprising critical flaw: despite a massive battery specification, the real-world battery life is reported as poor. This dichotomy defines the devicea masterpiece of imaging technology housed in a chassis that struggles to maintain the endurance expected of a flagship.
The Leica Camera System: A Return to Form
The undisputed highlight of the Xiaomi 17 Ultra is its camera array, which recaptures the high standards set by the Xiaomi 14 Ultra. The device features a 1-inch 50-megapixel main sensor equipped with optical image stabilization (OIS), ensuring professional-grade depth of field and clarity. Complementing the main sensor is a 50MP wide-angle lens and a staggering 200MP telephoto unit.
Xiaomi and Leica have engineered a versatile zoom system that stands out in the 2026 landscape. The setup offers a seamless mechanical zoom range between 3.2x (75mm) and 4.3x (100mm), allowing for consistent color and contrast without the jarring shifts often seen in other multi-lens systems. The optical capabilities extend to an 8.6x (200mm) zoom, producing detailed images that rival the legendary optical zoom performance of previous Samsung flagships. Whether shooting at the base 23mm focal length or pushing to 120x digital zoom, the camera delivers punchy, vibrant, and professional-looking results.
Design and Display: An Identity Crisis
Unlike its predecessors, the Xiaomi 17 Ultra has abandoned the distinct Leica-inspired aesthetic that defined the Ultra series. The new design adopts a more generic approach with flat aluminum sides and a flat fiberglass rear panel, reminiscent of an iPhone rather than a unique Xiaomi creation. While the device is reasonably thin at 8.2mm, the massive camera module creates a significant weight imbalance, making the 219-gram phone fatiguing to hold for long periods and unstable when placed on flat surfaces.
The review unit, finished in a "Starlit Green," was described as having the unfortunate aesthetic of a "70s bathroom suite," lacking the premium feel expected at this tier. On the front, however, the experience is redeemed by a 6.9-inch OLED display with a resolution of 2608 x 1200. The bezels are minimal, and the physical controls feature a thoughtful distinction: round volume keys separated from a stadium-shaped power button.
Performance and Specifications
Under the hood, the Xiaomi 17 Ultra is powered by the Qualcomm Snapdragon 8 Elite Gen 5 SoC, paired with 16GB of RAM and storage options ranging from 512GB to 1TB. The device runs on Android 16 overlaid with Xiaomi's Hyper OS 3. Biometric security is a strong point, with both face recognition and the fingerprint sensor operating quickly and reliably.
| Feature | Specification |
|---|---|
| Processor | Qualcomm Snapdragon 8 Elite Gen 5 |
| Main Camera | 50MP (1-inch sensor), OIS |
| Telephoto | 200MP (75mm - 100mm mechanical zoom) |
| Battery | 6,000mAh (90W wired / 50W wireless charging) |
| Display | 6.9-inch OLED (2608 x 1200) |
The Battery Paradox
A major point of contention is the battery performance. The spec sheet lists a massive 6,000mAh battery, which typically suggests multi-day endurance. However, real-world testing highlights "poor battery life" as a significant con. This suggests potential optimization issues with the new Hyper OS 3 or the power demands of the Snapdragon 8 Elite Gen 5 chipset. Despite the capacity, the device does not deliver the longevity one would assume from such a large cell.
Availability
As of late February 2026, Xiaomi has not announced official pricing. The phone is currently available in China and is expected to launch in the UK and Europe shortly. There are no plans for an official US release, meaning American buyers would need to rely on importing the device.
My Take
The Xiaomi 17 Ultra represents a fascinating but flawed evolution. The camera technology is undeniably top-tier, particularly the mechanical zoom implementation which solves a long-standing pain point in mobile photography. However, the shift to a generic design and the reported battery strugglesdespite a 6,000mAh cellare worrying. For photography enthusiasts, it might be the best phone of the year; for everyone else, the ergonomic issues and battery drain might be deal-breakers.
