Xiaomi 17 Pro review: specs, battery & used prices

Summary

The Xiaomi 17 Pro is Xiaomi's 2025 compact flagship, and its specifications read like a contradiction: a 6.3-inch body holding a 6,300 mAh battery — the largest cell ever fitted to a phone this size — alongside the Snapdragon 8 Elite Gen 5 and 100 W charging. It sells new for about $899, and early used listings for the 12/256 GB configuration sit near $846, reflecting how recently it launched.

Display and design

The 6.3-inch OLED runs at 120 Hz with a 1,200-nit peak — bright enough indoors, though our screen-quality score of 66/100 trails the 3,000-nit class leaders. The engineering story is the chassis: 192 g and a compactness score of 85/100 while containing a cell this size. IP68 protection is standard.

Performance

The Snapdragon 8 Elite Gen 5 is the fastest Android chip of its generation, and our gaming score of 99/100 is the highest we award — sustained 3D performance at the absolute front of the catalog. Thermal management holds up in the compact body, which makes the phone a genuine pick for mobile gaming where screen size is negotiable.

Camera

The triple 50 MP system — stabilised main, ultrawide, and telephoto — captures video up to 8K at 30 fps. Our camera score of 60/100 is top-tier: hardware and processing compete comfortably with larger flagships, though zoom reach is more modest than Xiaomi's Ultra line offers.

Battery and charging

This is the phone's headline: a 6,300 mAh battery scoring 66/100 on our battery-life axis — flagship-leading endurance in a compact body — with 100 W wired charging (80/100) restoring a full charge in about half an hour.

Verdict

The Xiaomi 17 Pro solves the compact-phone compromise: nothing else in the small-phone class pairs this endurance with this performance. Around $899 new with used prices already near $846, it is for buyers who want flagship speed without flagship size. Two caveats: the display is a step behind brighter rivals, and long-term US availability runs through import channels. If size is no constraint, the Xiaomi 15 Pro offers a bigger, brighter panel with the same battery philosophy.
