Asus ROG Phone 9 review: specs, battery & used prices

Summary

The Asus ROG Phone 9 is a 2024 gaming flagship on the Snapdragon 8 Elite, with a 6.78-inch 185 Hz OLED rated at 2500 nits, a 5800 mAh battery with 65 W charging, and an IP68 body at 227 grams. Our catalog scores it 79 on gaming and 93 on screen, with the 12/256 GB trim listed new near $999 and a single used example around $680. A 50-megapixel stabilized main camera records up to 8K30 video. The Asus ROG Phone 9 Pro is its higher-trim twin, and the Asus ROG Phone 7 is the earlier generation.

Display and design

The 6.78-inch OLED refreshes at 185 Hz with a 2500-nit peak, and our screen axis of 93 places it at the top of the catalog for brightness and motion clarity together. The sealed IP68 chassis at 227 grams keeps the mainstream-friendly direction the line adopted a generation earlier, with AirTrigger shoulder controls still built in. Rear accent animations remain a gamer-pleasing flourish on the Pro trim.

Performance

The Snapdragon 8 Elite earns an everyday axis of 84 and a gaming axis of 79 in our model, one of the strongest sustained-gaming scores in our records: the efficiency-focused elite platform holds frame rates where predecessors throttled, and the larger 5800 mAh cell extends sessions. Daily use is indistinguishable from a top conventional flagship. Our records leave the software window closing now, a consideration at this price.

Camera

A 50-megapixel main sensor with optical stabilization heads the rear array with ultrawide and telephoto partners, recording up to 8K30. The camera axis of 37 sits a step below the mainstream flagships of the year, which is to say daylight and stabilized clips are dependable while processing finesse is not the point of this phone. It remains the capable-afterthought the line has always carried.

Battery and charging

The 5800 mAh battery scores 56 on our battery axis, a full day of hard gaming or up to two of ordinary use, and the 65 W charger scores 46, refilling in about an hour. Bypass charging keeps long sessions off the cell entirely, and the platform's efficiency does more for endurance than raw capacity alone. Wireless charging is present on this generation.

Verdict

The ROG Phone 9 is the refined gaming flagship of its year, pairing a 185 Hz 2500-nit OLED with the strongest sustained-gaming platform in our records at $999 new, or near $680 used on our single tracked listing. Its software window in our records is closing now, which tempers the price argument. For mobile players who want a phone that is also a complete daily driver, it is the cleanest ROG formula yet, with the ROG Phone 9 Pro as the fully loaded variant.
