Asus ROG Phone 9 Pro review: specs, battery & used prices
Hands-on-style overview of the Asus ROG Phone 9 Pro with Qualcomm Snapdragon 8 Elite (Gen 4): screen, cameras, battery, performance and what it costs used.
Summary
The Asus ROG Phone 9 Pro is a 2024 gaming phone through and through: a 185 Hz OLED — the highest refresh rate we track — the Snapdragon 8 Elite, a 5,800 mAh battery, shoulder triggers, and Asus's Armoury Crate gaming suite. It launched at $1,199 for the 16/512 GB configuration, and that tier now trades used for around $1,125: a resale score of 100/100 makes it one of the stickiest-value phones in the catalog.
Display and design
The 6.78-inch OLED combines a 185 Hz refresh rate with a 2,500-nit peak for a screen-quality score of 93/100 — the smoothest display in the catalog matters most in fast shooters. At 227 g with gaming-oriented ergonomics and a compactness score of 65/100, it is unapologetically a gaming tool first, rated IP68.
Performance
The Snapdragon 8 Elite plus Asus's extended vapour chamber and bypass charging deliver our gaming score of 79/100 with class-leading sustained behaviour: long sessions hold frame rates where conventional flagships throttle. AirTrigger shoulder buttons and a huge 720 Hz touch sampling rate complete the package. The cost is software: two years of updates means the runway is already spent — a 2026 buyer owns the current build as its last.
Camera
Cameras are the concession: a 50 MP stabilised main sensor with ultrawide and 3x telephoto companions reaches 8K at 30 fps, and our camera score of 48/100 is mid-catalog — competent, never the argument. Gaming phones accept this trade; photographers should not.
Battery and charging
The 5,800 mAh battery earns a 56/100 battery-life score with bypass charging that feeds the phone directly during plugged-in sessions, extending cell life. 65 W wired charging scores 46/100 — a full charge in under an hour.
Verdict
The ROG Phone 9 Pro is the definitive 2024 gaming phone and still the one to beat for sustained performance — around $1,125 used, held up by that 100/100 resale score. Buy it for gaming; accept the mid camera and finished update window. For the same formula at roughly $450 less, the previous ROG Phone 8 Pro remains a compelling used buy, and its price curve shows how quickly gaming-flagship values settle once support ends.
