The Xiaomi 15 Ultra is here, and it’s aiming directly at the crown for the best camera phone in 2025. Packed with cutting-edge specs, a refined design, and a camera system that rivals professional gear, Xiaomi’s latest Ultra model is a serious contender in the flagship space.
But is it worth your money? Here’s our full breakdown.
Premium Design & Build: Durable, Stylish, and Practical
Xiaomi has crafted a phone that feels as premium as it looks. The aluminum frame and vegan leather finish give it a distinct, luxurious feel, while the new two-tone design adds extra flair. The enormous camera module isn’t just for show—it houses one of the most advanced mobile camera systems on the market.
- IP68 water and dust resistance
- Xiaomi Shield Glass for improved durability
- New camera grip accessory with shutter button, zoom dial, and lanyard mount
- Filter-compatible lens rings for pro-level customization
Stunning 1440p OLED Display with Dolby Vision
The 6.73-inch LTPO OLED display is a visual treat:
- 1440p resolution at 120Hz refresh rate
- 12-bit color for ultra-rich tones
- Peak brightness of 1600 nits – great for outdoor use
- HDR10+ and Dolby Vision support
Sound, Biometrics & Extras: Fully Loaded
The stereo speakers on the Xiaomi 15 Ultra are powerful and deliver a full-bodied sound ideal for music and media. On the security front, the ultrasonic fingerprint sensor is fast and accurate—an upgrade over last year’s optical sensor.
And for legacy tech lovers: the IR blaster is still here, letting you control appliances right from your phone.
Software & AI: Xiaomi HyperOS 2 with Google Gemini Integration
Out of the box, the Xiaomi 15 Ultra runs Android 15 with Xiaomi’s new HyperOS 2, offering a cleaner, faster UI and deeper AI integration. AI tools are a major highlight this year:
- Real-time translation
- AI photo editing tools
- Smart note summarization
- Google’s Gemini AI assistant fully integrated
Xiaomi also promises 4 years of OS updates and 6 years of security patches, making it a solid long-term investment.
Performance: Snapdragon 8 Gen 3 Elite
The Xiaomi 15 Ultra is powered by the Snapdragon 8 Gen 3 Elite processor, making it one of the most powerful Android smartphones in 2025. You can expect:
- Smooth multitasking
- High-end mobile gaming performance
- Fast app loading and switching
However, thermal throttling can occur during extended heavy use—particularly during 8K video recording or long gaming sessions.
Battery Life & Charging: All-Day Power, Super Fast Charging
Battery life is excellent thanks to a large 5410 mAh battery in global models (6000 mAh in China).
- 90W fast charging (0–72% in 30 minutes)
- 51-minute full charge
- Wireless charging supported
- Accessory battery grip adds 2000 mAh
Sadly, no charger is included in the box—something to keep in mind.
