Price and Availability
The Xiaomi 15 Ultra was officially announced in China on February 27, with a global debut in Barcelona following shortly after on March 2. Sales began immediately in select markets across Europe and Asia, with the base variant priced at £1,299 / €1,599. A higher-tier 1TB model is available in certain regions, costing an additional £200. Unfortunately, Xiaomi still does not officially sell its smartphones in the United States or Australia. As a result, users in these regions would have to import the device, which also means giving up direct carrier support and some localized services.
Technical Specifications
The Xiaomi 15 Ultra is packed with high-end specifications that place it firmly in flagship territory:
Processor: Qualcomm Snapdragon 8 Elite
Display: 6.73-inch AMOLED, QHD+, 120Hz refresh rate
Camera Array: 50MP main (1-inch sensor), 200MP telephoto, 50MP ultra-wide, 50MP periscope
Front Camera: 32MP
Battery: 5,300mAh (China) / 5,100mAh (EU)
Charging: 90W wired, 50W wireless

Build: Titanium frame, Gorilla Glass Armor, IP68 rating
This combination of components ensures that the phone performs at the highest level across almost every task—gaming, photography, video editing, and productivity.
Design and Build Quality
The Xiaomi 15 Ultra is visually striking, adopting a premium design philosophy that doesn’t deviate drastically from its predecessor but refines it in meaningful ways. The chassis is made of titanium, which not only enhances its durability but gives the phone a luxurious in-hand feel. The rear camera module remains massive, commanding attention with its circular housing and textured detailing. It’s a design that speaks power and capability, even before the phone is switched on.
Improved drop resistance is another win. Xiaomi employs Gorilla Glass Armor, which boasts better resilience against drops and scratches compared to previous materials. Despite the phone’s considerable size and weight, ergonomics are surprisingly manageable due to thoughtful balance and curvature in its construction.
Display and Audio Experience
The 6.73-inch AMOLED display on the 15 Ultra is among the best available on any smartphone today. With QHD+ resolution, adaptive 120Hz refresh rate, and support for Dolby Vision and HDR10+, visuals appear vibrant, crisp, and fluid. Brightness levels peak above 3000 nits, ensuring clear readability even under direct sunlight.
This display excels whether you’re streaming high-definition content, editing photos, or simply navigating through the user interface. Color reproduction is highly accurate, and contrast levels are nearly perfect thanks to OLED technology. On the audio front, the dual stereo speakers deliver powerful, clear sound with good spatial separation, making media consumption immersive.
Software and User Interface
The 15 Ultra ships with HyperOS 2.0, Xiaomi’s custom Android skin layered atop Android 15. While feature-rich and visually modern, HyperOS continues to suffer from complexity and inconsistency. Navigating menus can feel unintuitive at times, and there are occasional hiccups that detract from the fluidity expected at this price point.
AI enhancements are among the more notable additions this year. Real-time translation, productivity tools, and photo editing features powered by artificial intelligence work reliably in most cases. However, some functions—such as Reflection Removal—still need polish, as they failed consistently during testing.
Xiaomi has promised four years of OS updates and six years of security patches, which is an improvement but still lags behind the likes of Samsung and Google. For users prioritizing long-term support, this remains a key drawback.
Photography and Videography
Photography is the standout feature of the Xiaomi 15 Ultra, and the collaboration with Leica continues to yield exceptional results. The upgraded 1/1.4-inch 200MP telephoto sensor joins the already impressive 1-inch main sensor, offering stunning zoom performance without sacrificing detail or color accuracy.
Photos taken on the 15 Ultra feel rich and cinematic. The color science leans toward Leica’s signature look—muted yet natural, with excellent dynamic range. The camera also shines in low light, capturing fine textures and subtle lighting with minimal noise.
Videography is similarly robust. Support for 10-bit LOG video capture, real-time LUTs, and advanced stabilization puts the 15 Ultra on par with dedicated camera gear for mobile filmmakers. The software-based enhancements make manual control more accessible, expanding creative potential for those who want to push beyond point-and-shoot photography.
Performance and Gaming
Under the hood, the Xiaomi 15 Ultra is powered by Qualcomm’s Snapdragon 8 Elite, a custom variant offering even more headroom than the standard Snapdragon 8 Gen 3. Whether you’re multitasking across several demanding apps, editing 4K video, or gaming at the highest settings, this chipset delivers top-tier responsiveness.
Thanks to Xiaomi’s HyperCore resource management and IceCool vapor chamber cooling, the phone remains stable and cool under load. Storage is blazing fast with UFS 4.0, and LPDDR5X RAM ensures seamless transitions and app switching. Benchmarks place the 15 Ultra comfortably ahead of most Android competitors, rivaling even Apple’s silicon in certain tasks.
Gaming experiences are particularly satisfying. Frame rates remain consistent across graphically intensive titles, and thermal throttling is kept in check better than most phones in its class.
Battery and Charging
Battery performance, surprisingly, is one of the weaker elements of the Xiaomi 15 Ultra. The EU model ships with a 5,100mAh battery, slightly smaller than the 5,300mAh unit in the Chinese variant. This change—presumably due to regulatory differences—impacts real-world usage. A full day of moderate to heavy use is possible, but battery anxiety creeps in during extended screen time or heavy multitasking.
Charging speeds, on the other hand, are stellar. The phone supports 90W wired charging and 50W wireless charging, allowing for a near-full charge in under 30 minutes. Wireless charging also remains practical and efficient, though it works best with Xiaomi’s proprietary accessories.
Despite the fast top-ups, the actual longevity between charges leaves room for improvement, especially when compared to rivals like the Galaxy S24 Ultra or iPhone 16 Pro Max.
