Xiaomi officially unveiled the Xiaomi 17 Max at its ecosystem event. The smartphone is already available for pre-order in China, with open sales starting May 25. With a national subsidy, the starting price is 4299 yuan, or about $594, and the spec sheet makes it one of the strongest models in the company's lineup.
The standout feature is an 8000 mAh battery. It uses an anode with 16% silicon content, achieving an energy density of 894 Wh/L. This silicon-carbon chemistry allows a large battery to fit in a body that doesn't feel overly bulky. In an official Xiaomi test, continuous video playback on Bilibili with the screen on lasted 33.3 hours, surpassing the combined runtime of two fully charged iPhone 17 Pro Max units.
Charging and power management are handled by proprietary Surge P3 and Surge G2 chips. The phone supports 100W wired and 50W wireless charging, so the massive battery doesn't require an all-night charge. According to company claims, a full charge takes about 60 to 70 minutes.
The display is another key highlight. Xiaomi bets on SuperPixel technology, which aims to deliver perceived 2K sharpness with power consumption close to that of a 1.5K panel. The OLED display uses M10 material, supports LTPO with a refresh rate from 1 to 120 Hz, and peaks at 3500 nits of brightness for outdoor visibility. Durability is provided by Dragon Crystal Glass Gen 3, which is said to offer 20 times better drop resistance than standard glass.
The camera system is co-developed with Leica and includes three sensors, led by a 200-megapixel main sensor with a 1/1.4-inch format. The optics feature a special pyramid coating with high light transmittance to reduce internal reflections and improve light capture. Multi-frame merging at 200 MP is used to boost detail, dynamic range, and low-light performance.
The telephoto periscope module is based on a 1/2-inch sensor and offers 3x optical zoom, along with 6x lossless zoom. An unusual feature is the ability to take macro shots at 15 cm using the telephoto lens, useful for subjects like objects, food, and fine details without a dedicated macro camera.
For gaming, the Xiaomi 17 Max includes a cooling system with a 3D ring cold pump. The company claims it can sustain 5.7 hours of Genshin Impact at maximum settings with full frame rate. Combined with the Snapdragon 8 Elite Gen 5, a large display, and an 8000 mAh battery, this makes the device not only a camera phone and a long-lasting performer but also a serious gaming machine.
