Despite its large 6,000 mAh battery, the phone maintains a balanced weight of 225g. The button placement is ergonomic, with a textured power button for easy identification. It feels solid, expensive, and carries an IP69 rating, meaning it can survive high-pressure water jets and deep submersion.
Display Quality
Xiaomi has equipped this device with the C10 LTPO AMOLED panel, pushing a staggering 35,00 nits of peak brightness. Outdoor visibility is the best in the industry, making the screen perfectly legible even under the harsh Cambodian sun.
The 2K resolution provides incredible sharpness for editing photos, while the 1-144Hz adaptive refresh rate ensures ultra-smooth scrolling. Color accuracy is professionally tuned to the Delta E < 0.3 standard, making it a reliable tool for color-grading videos directly on the device.
Performance & Daily Usage
Powered by the Snapdragon 8 Elite Gen 5, the Xiaomi 17 Ultra is a beast. App opening speeds are instantaneous, and with up to 24GB of RAM, you can keep dozens of heavy apps like Premiere Rush or Lightroom open without the phone breaking a sweat.
During daily use—including heavy multitasking, 5G hotspot tethering, and GPS navigation—there is zero lag. HyperOS 3.0 is highly optimized, offering fluid animations and a “Workstation Mode” that turns the phone into a desktop-like experience when connected to a monitor.
Gaming Performance
Driven by the Snapdragon 8 Elite Gen 5, this device handles AAA titles like Genshin Impact at a stable 120 FPS. The upgraded 3D Dual-Channel IceLoop cooling system prevents thermal throttling during marathon sessions. With a 300Hz touch sampling rate and a vivid 3,500-nit display, it provides a highly responsive and immersive competitive gaming environment.
This phone is a “silent” gaming giant.
- Games Tested: Genshin Impact, Honkai: Star Rail, and Warzone Mobile.
- Settings: All games ran at Max/Ultra settings at 90-120 FPS.
- Thermals: The new “IceLoop” cooling system keeps the device under 42°C even after an hour of heavy gaming.
- FPS Stability: Frames remained rock-solid with no noticeable throttling, making it a top-tier choice for competitive mobile gamers.
Camera
The Xiaomi 17 Ultra is a photography powerhouse, featuring a 1-inch Light Fusion 1050L main sensor with LOFIC HDR technology for unmatched dynamic range. Its standout feature is the 200MP periscope telephoto lens, offering a mechanical 75–100mm lossless zoom. Whether shooting 8K video or Leica-textured portraits, the detail and low-light clarity are industry-leading.
The Xiaomi 17 Ultra is essentially a camera that happens to be a phone.
- Daylight: The 1-inch main sensor produces a natural shallow depth-of-field (bokeh) that no software can truly mimic.
- Low-Light: Its “Ultra-Night” algorithm captures detail in shadows while maintaining a realistic night-time look without artificial noise.
- Portrait: The 75mm floating telephoto lens is arguably the best for portraits, providing perfect skin tones and sharpness.
- Front Camera: The 4th Gen Under-Display Camera is nearly invisible and captures much clearer selfies than previous iterations.
Battery Life & Charging
The 6,000 mAh Silicon-Carbon battery is a game-changer. Even with the 2K display and 144Hz enabled, we averaged 9+ hours of Screen-on Time (SoT). It easily lasts a full day of heavy photography.
Charging is handled by 90W HyperCharge (wired) and 50W wireless. You can go from 1% to 100% in roughly 20 minutes using the included charger. It is one of the few brands that still includes the high-speed power brick in the box.
Connectivity & Features
Equipped with Xiaomi Astral Communication, the 17 Ultra ensures rock-solid 5G and Wi-Fi 7 signals even in low-coverage areas. It introduces Bluetooth 6.0 for low-latency audio and unique offline voice calling up to 1.5km. Integrated Google Gemini AI and an ultrasonic fingerprint sensor round out a truly futuristic, high-security flagship experience.
