Introduction
Xiaomi has done it again! The launch of the Xiaomi 15 Ultra has created shockwaves across the tech world, and for good reason. With unmatched specs, Leica-powered cameras, and performance that leaves both the iPhone 15 Pro Max and Samsung Galaxy S24 Ultra in the dust, Xiaomi is boldly claiming the top flagship spot in 2025.
In this full in-depth review, we break down everything you need to know: design, display, camera, performance, battery life, price, and our final verdict. Is this the best Android flagship of the year? Let’s find out.
Unboxing & First Impressions
Opening the box, you’re greeted with a premium unboxing experience. Inside:
- Xiaomi 15 Ultra handset
- 90W charger (yes, included!)
- USB-C cable
- Transparent case
- SIM ejector tool
- Quick guide and warranty card
The phone immediately feels luxurious — it’s heavy, solid, and screams “flagship.” Whether you choose the ceramic or vegan leather finish, you’re holding something special.
Design & Build Quality
Xiaomi has refined the design of the 14 Ultra and made it even better. The Xiaomi 15 Ultra boasts a curved-edge AMOLED front, ultra-slim bezels, and a smooth matte finish on the back. The giant circular camera module is still there — love it or hate it — but it looks more refined this year.
Build Materials:
- Front: Gorilla Glass Victus 2
- Back: Ceramic / Vegan Leather
- Frame: Aerospace-grade aluminum
IP68 certification is present, making it dust and water-resistant. The phone feels like a direct rival to iPhones in terms of craftsmanship.
Display – Stunning & Bright
The Xiaomi 15 Ultra features a 6.73-inch LTPO AMOLED display with:
- QHD+ resolution (3200×1440)
- 120Hz adaptive refresh rate
- Peak brightness of 3000 nits
- Dolby Vision & HDR10+
Outdoor visibility is excellent, and the colors are vibrant yet natural. Whether you’re gaming or watching 4K HDR videos, the display performs flawlessly.
In simple words: It beats the iPhone 15 Pro Max’s Super Retina display in both brightness and color depth.
Performance – Speed Demon
Under the hood, Xiaomi has packed the Snapdragon 8 Gen 4, paired with:
- 12GB or 16GB LPDDR5X RAM
- 256GB / 512GB / 1TB UFS 4.0 storage
Benchmark Scores:
- Geekbench 6: 2350 (Single) / 7200 (Multi)
- AnTuTu Score: 1.9 million+
In real-world use, the phone feels lightning-fast. Multitasking, app switching, and gaming are silky smooth.
Gaming Test Results:
- Genshin Impact: Max settings, no frame drops
- PUBG Mobile: Ultra HDR + 90FPS support
- COD Mobile: Highest graphics with zero lag
The phone barely heats up thanks to its new liquid cooling system.
Camera – Leica Magic Continues
The main highlight? The camera system. Co-engineered with Leica, Xiaomi 15 Ultra features:
- Main: 50MP 1-inch Sony LYT-900 sensor (f/1.6)
- Ultra-wide: 50MP with 120° FOV
- Periscope Telephoto: 50MP, 5x optical zoom
- Telephoto 2: 200MP Leica ultra-telephoto, 3.2x zoom
- Front Camera: 32MP with 4K video
Real-World Shots:
- Daylight: Ultra-sharp, Leica color grading gives cinematic tones.
- Low Light: Best in class — brighter than iPhone 15 Pro Max.
- Portraits: Natural skin tones and perfect edge detection.
- Zoom: The new 200MP Leica ultra-telephoto lens captures unbelievable detail even at 30x and beyond.
- Video: 8K recording with stabilization, HDR10+, and cinematic modes.
In fact, the Xiaomi 15 Ultra is now competing directly with camera kings like Sony Xperia 1 VII, which we praised for its DSLR-level camera and stunning 4K display in this review.
Still, if you value manual controls, color science, and pure image quality, don’t miss our breakdown of why no one can beat Sony in the smartphone game here.
Both Sony and Xiaomi are pushing the limits — but Xiaomi’s partnership with Leica and its computational photography edge might just give it the upper hand for most users.
If you love mobile photography, this is the phone to get.

- 50W wireless = 0 to 100% in 45 minutes
