Reviews Xiaomi 15 Ultra, The Xiaomi 15 Ultra has stormed onto the smartphone scene in 2025, positioning itself as a formidable contender in the flagship market, particularly for those who prioritize mobile photography. With its Leica-backed camera system, cutting-edge performance, and sleek design, this phone aims to redefine what a smartphone can achieve. In this blog post, we’ll dive deep into the Xiaomi 15 Ultra’s features, focusing on its camera capabilities, design, performance, and overall user experience, tailored specifically for tech enthusiasts who demand the best from their devices. This review draws on insights from recent tech blogs to provide a comprehensive look at what makes this phone stand out.
A Design That Screams Premium
At 229 grams, it’s on the heavier side, and the large, volcano-shaped camera module creates a noticeable bump, which may affect ergonomics for some users. However, the included transparent silicone case and the optional Photography Kit Legend Edition, which adds a camera grip with a shutter button, zoom lever, and 2000mAh battery pack, enhance both functionality and grip. With IP68 water and dust resistance and Xiaomi’s Shield Glass 2.0, the 15 Ultra is built to withstand daily wear and tear, surviving drops and tumbles during testing without a scratch.
The 6.73-inch WQHD+ LTPO AMOLED display is a standout, boasting a 120Hz refresh rate, 3200 nits peak brightness, and Dolby Vision support. Its quad-curved design makes swiping smooth, though it can lead to occasional mispresses due to the curved edges. Tech enthusiasts will appreciate the customizable color modes, including the highly accurate Original Color PRO, and features like Wet Touch technology for usability in rain.
Camera: A Leica-Powered Masterpiece
The Xiaomi 15 Ultra’s camera system is its crown jewel, designed for photography enthusiasts who want professional-grade results from a smartphone. The quad-camera setup, developed in partnership with Leica, includes:
- 50MP Main Sensor (Sony LYT-900, 1-inch, f/1.63): Delivers sharp, detailed images with natural colors and excellent dynamic range, particularly in daylight. Low-light shots retain detail with minimal noise, though some warm color casts may appear indoors.
- 50MP Ultra-Wide (Samsung ISOCELL JN5): Offers solid performance but falls short in dynamic range compared to the main sensor.
- 50MP Floating Telephoto (2.6x zoom): Provides versatile macro and portrait capabilities, though group shots may struggle with a narrow depth of field.
- 200MP Periscope Telephoto (4.3x zoom): A standout feature, this lens captures stunning detail at long range, excelling in portrait and macro photography. It’s a step up from the Xiaomi 14 Ultra’s 5x zoom but sacrifices some versatility.
Leica’s Authentic and Vibrant color profiles allow users to choose between natural tones and punchier hues, with the Authentic mode earning praise for its realistic rendering. The camera app includes Leica-designed filters (BW, Sepia, Blue) and supports 8K video at 30FPS and 4K at 120FPS with Dolby Vision, making it a videographer’s dream. The optional Photography Kit transforms the phone into a point-and-shoot camera, complete with manual controls for EV, shutter, ISO, and white balance, appealing to serious shutterbugs.
However, there are minor drawbacks. The loss of the variable aperture from the Xiaomi 14 Ultra limits depth-of-field control, which may disappoint landscape photographers. Additionally, slight color inconsistencies between lenses and occasional highlight blowouts were noted in testing. Despite these, the 15 Ultra’s camera system is widely regarded as one of the best in 2025, rivaling the likes of the iPhone 16 Pro and Vivo X200 Ultra.
Performance and Software: Power Meets Polish
Powered by Qualcomm’s Snapdragon 8 Elite and paired with up to 16GB of LPDDR5X RAM and UFS 4.1 storage, the Xiaomi 15 Ultra is a performance beast. It handles multitasking, gaming (titles like Wuthering Waves and Honkai: Star Rail), and heavy workloads with ease, thanks to excellent thermal management. The Adreno 830 GPU ensures smooth graphics, making it a favorite for mobile gamers.
Running HyperOS 2 based on Android 15, the phone offers a fluid interface with Google Gemini and Circle to Search integration. Xiaomi’s AI tools, including text summarization, proofreading, and photo editing (Expand, Erase Pro, Enhance), are useful but require an internet connection. While the software is polished, the promised four OS upgrades and six years of security patches lag behind competitors like the Galaxy S25, which offer seven OS upgrades.
Battery Life and Charging: Reliable but Not Revolutionary
The 15 Ultra’s 5410mAh silicon-carbide battery is a significant upgrade over its predecessor, lasting up to a day and a half under normal use. It supports 90W wired and 80W wireless charging via Xiaomi’s HyperCharge technology, with a 67W charger restoring 46% in 15 minutes and 81% in 30 minutes. However, the lack of a charger in the box and the absence of 120W charging (available on some previous Xiaomi models) disappointed some reviewers.
Who Is It For?
The Xiaomi 15 Ultra is a dream device for photography enthusiasts and tech lovers who want a phone that doubles as a professional-grade camera. Its high-end specs, stunning display, and robust performance make it a well-rounded flagship, but its premium price (starting at €1499 or S$1699) and limited availability in markets like the U.S. may deter casual users. If you’re passionate about mobile photography and don’t mind the weight or camera bump, this phone is a top-tier choice.
FAQs
For photography enthusiasts, the Leica-backed camera system and premium features justify the €1499 price tag. However, casual users may find better value in more affordable flagships like the Xiaomi 15 or Galaxy S25.
