Compact size, huge performance and a two-day battery

The meticulously crafted 6.3-inch LTPO AMOLED display with 3500 nits of brightness and video up to 8K ensure that every experience looks as good as it deserves.

A display that redefines the compact category

The Xiaomi 17 features a 6.3-inch LTPO AMOLED panel with a resolution of 2656 × 1220px and a density of 460 PPI – one of the highest in its entire smartphone class. The variable 1–120Hz refresh rate automatically adapts to the content on screen, saving battery when viewing static text and switching to full fluidity for fast-paced games or scrolling. A peak brightness of 3500 nits guarantees perfect readability even in direct sunlight, while 2160Hz PWM dimming eliminates flickering and protects your eyes during prolonged use. The display shows 68 billion colours in the full DCI-P3 colour space, supports both HDR10+ and Dolby Vision, and is protected by proprietary Xiaomi Shield Glass, which is resistant to scratches and accidental drops. The result is a display that would not be out of place on a flagship phone a class above.

The smallest flagship with big ambitions

With dimensions of 151.1 × 71.6 × 8.06mm and a weight of just 191g, the Xiaomi 17 phone is one of the most compact and lightweight flagship smartphones on the market. The slim aluminium frame combined with the precision-machined glass body creates a premium feel that you will appreciate from the very first touch. The phone sits naturally and securely in the palm of your hand – one-handed operation is a given, not a compromise. Xiaomi Shield Glass protects the display from everyday hazards, and the IP68 certification provides peace of mind in the rain or during accidental contact with water. Available in several elegant colour options, it proves that true premium design does not need large dimensions to attract attention.

The Xiaomi 17 features three Leica lenses

The Xiaomi 17's camera system is built around a trio of 50Mpx Leica lenses that cover the full spectrum of photographic situations, from wide landscapes to distant details. Each lens has a precision multi-layer optical coating that suppresses glare and haze, resulting in images with true-to-life colours and crystal clarity, regardless of lighting conditions. Thanks to the uniform 50Mpx resolution across the entire setup, you maintain full image quality every time you switch lenses, without having to think about which one to choose.

The Xiaomi 17 has a large sensor for great results in any light

At the heart of the setup is a 50Mpx main lens with a 23mm focal length, an f/1.67 aperture and a 1/1.31" sensor, which captures significantly more light than standard mobile phone cameras. Optical Image Stabilisation (OIS) eliminates shaky hands, and dual-pixel PDAF guarantees fast and accurate focusing even when in motion. The result is sharp, detailed images with a natural bokeh effect – whether you're shooting in broad daylight or late in the evening.

Telephoto and ultra-wide-angle lenses

The 50Mpx telephoto lens, with its 60mm focal length and 2.6× optical zoom, opens up a world of detail that would otherwise remain hidden – portraits with a natural perspective, distant architecture, or sporting moments captured sharply even from afar, all with OIS. At the other end of the spectrum is the 50Mpx ultra-wide-angle lens with a 17mm focal length and a 102° field of view, which effortlessly captures expansive landscapes, interiors, or group photos. Both lenses are fully equipped for night photography and can also handle macro shots with ease.

Professional video – 8K, Dolby Vision and LOG format for demanding creators

The Xiaomi 17 isn't just a camera – it's a comprehensive tool for mobile videography. You can shoot video in up to 8K@30fps with HDR or in 4K@60fps with support for 10-bit Dolby Vision and 10-bit LOG for professional post-production and colour grading. Gyro-EIS stabilisation ensures smooth shots even when filming on the move, and slow-motion video up to 720p@1920fps opens up creative possibilities that were once exclusive to professional cameras. The stereo speakers with Dolby Atmos then ensure the sound matches the image quality.

50Mpx for a natural, unembellished portrait

The front camera of the Xiaomi 17 phone offers a 50Mpx sensor with a 21mm focal length, f/2.2 aperture, and PDAF autofocus, which ensures fast and precise focusing even when moving. Every portrait captures the natural texture of skin with true-to-life tones, without excessive editing. Selfie videos can be shot in up to 4K@60fps with HDR10+ and gyro-EIS stabilisation, so even handheld footage looks professional. Whether you're taking a picture of yourself or a group of friends, the wide 21mm lens always fits plenty in the frame.

The Xiaomi smartphone uses Snapdragon 8 Elite Gen 5 for uncompromising performance

The Xiaomi 17 smartphone is powered by the latest Qualcomm Snapdragon 8 Elite Gen 5, manufactured using a cutting-edge 3nm process, which delivers a 20% increase in CPU performance, a 23% faster GPU, and 37% more powerful AI processing compared to the previous generation. The octa-core Oryon V3 processor with a clock speed of up to 4.6GHz, combined with the Adreno 840 graphics chip, handles demanding games, 4K video editing, and running dozens of apps in parallel. Fast LPDDR5X memory and UFS 4.1 storage ensure instant data loading and a snappy system response under all circumstances.

Xiaomi 17 uses unique IceLoop cooling

Performance on paper is one thing – sustaining it under long-term load is another. That's why the Xiaomi 17 comes with a proprietary 3D IceLoop cooling system, which uses a bionic microstructure vapour chamber inspired by natural structures for maximum heat transfer. An extensive heat dissipation area of 4497mm² disperses heat evenly across the entire phone body, providing 50% higher thermal conductivity compared to standard solutions.

A battery that keeps up with your lifestyle

It hides a true capacity of 6330mAh – and in practice, that means battery life that easily covers a full day of demanding use and more. 100W wired charging tops up the battery from zero to full in a matter of minutes, so waiting by the socket is a thing of the past. Convenient 50W wireless charging will be appreciated by those who prefer a cable-free life, and 22.5W reverse wired charging lets you charge other devices from the phone in an emergency. The Xiaomi 17 thus offers a complete charging ecosystem that covers every scenario.

The Xiaomi 17 mobile phone can withstand a lot

The durability of the Xiaomi 17 isn't just a marketing slogan – its IP68 certification guarantees protection against dust and submersion in up to 4 metres of water for 30 minutes, so rain, puddles, or an unexpected encounter with water are no problem at all. The front Xiaomi Shield Glass protects the display from scratches and impacts during daily use, while the aluminium frame gives the body the necessary strength without adding unnecessary weight. In a compact body just 8.06mm thick, you get a phone that looks premium, feels secure in your hand, and will easily survive whatever everyday life throws at it.
