What makes this phone particularly compelling are its three standout features: uncompromising gaming performance powered by the latest Snapdragon chipset, industry-leading battery life that keeps you gaming longer, and an advanced cooling system that maintains peak performance even during extended gaming sessions. These elements combine to create a device that doesn’t just compete in the gaming phone space—it defines it.

This comprehensive review will put the ROG Phone 9 Pro through its paces across multiple usage scenarios. We’ll test its gaming capabilities with demanding titles, evaluate its performance for media consumption and everyday tasks, examine its camera system for content creation, and assess whether its premium price tag delivers genuine value for different types of users.

Design & Build Quality

The ROG Phone 9 Pro commands attention with its distinctive gaming aesthetic while maintaining surprising refinement. Measuring 163 x 77 x 8.9mm and weighing 227 grams, this phone sits firmly in flagship territory for size and weight, though it’s noticeably heavier than most conventional smartphones.

ASUS has constructed the device using premium materials throughout. The frame combines aerospace-grade aluminum with Gorilla Glass Victus 2 protection on both front and back panels. The phone achieves an IP68 rating for water and dust resistance, a welcome addition that addresses one of the most common criticisms of previous ROG models.

The back panel features ASUS’s signature AniMe Vision LED matrix display, allowing for customizable animations, notifications, and personalization options. While some may view this as gimmicky, it serves practical purposes like displaying battery percentage, incoming calls, or gaming status without needing to flip the phone over.

Gaming-specific design elements include physical AirTrigger buttons that provide tactile feedback during gameplay, multiple USB-C ports (one on the side for unimpeded charging during landscape gaming), and a comprehensive cooling system with external vents. The included case accessories enhance the gaming experience with additional trigger buttons and improved heat dissipation.

Ergonomically, the ROG Phone 9 Pro excels during extended gaming sessions. The weight distribution feels balanced in landscape orientation, and the textured finish provides secure grip even during intense gaming moments. Button placement is intuitive, with the power button and volume rockers positioned for easy access whether gaming or using the phone normally.

Display Excellence

The ROG Phone 9 Pro features a 6.78-inch AMOLED display with 2448 x 1080 resolution and a variable refresh rate up to 165Hz. The LTPO technology automatically adjusts refresh rates based on content, optimizing battery life without sacrificing smoothness where it matters most.

Brightness performance impresses across different conditions. The display reaches 1000 nits in typical usage and peaks at 2500 nits for HDR content, ensuring excellent outdoor visibility even in direct sunlight. Indoor usage reveals rich colors and deep blacks characteristic of high-quality AMOLED panels.

Color accuracy meets professional standards with support for DCI-P3 and sRGB color spaces. HDR10+ certification delivers enhanced contrast and color depth when consuming compatible content. Gaming-specific display modes through the Game Genie interface allow for fine-tuning of color temperature, contrast, and saturation to match personal preferences or optimize visibility in specific game genres.

The display’s responsiveness sets it apart from conventional smartphones. With a 720Hz touch sampling rate and reduced touch latency, the screen responds instantaneously to inputs during gaming. Ghosting and motion blur are virtually eliminated, even during fast-paced action sequences, creating a smooth visual experience that competitive gamers will appreciate.

Performance & Thermals

Under the hood, the ROG Phone 9 Pro runs on Qualcomm’s flagship Snapdragon 8 Gen 3 processor, paired with up to 16GB of LPDDR5X RAM and 512GB of UFS 4.0 storage. This hardware combination delivers exceptional raw performance that handles any current mobile game or application without hesitation.

Benchmark results position the ROG Phone 9 Pro among the highest-performing Android devices available. AnTuTu scores consistently exceed 1.6 million points, while Geekbench 6 results show impressive single-core and multi-core performance that rivals desktop processors from just a few years ago.

Real-world gaming performance lives up to the benchmark promises. Demanding titles like Genshin Impact run smoothly at maximum settings with sustained frame rates above 60fps.

The cooling system deserves special recognition for its effectiveness. ASUS’s GameCool 8 thermal management combines a large vapor chamber, graphite thermal pads, and strategically placed heat dissipation elements. During our testing, the phone maintained peak performance for over two hours of continuous gaming without thermal throttling.

Special features like bypass charging mode prevent battery heat generation during extended gaming sessions by routing power directly to the system while plugged in. This feature alone can extend comfortable gaming time significantly while preserving long-term battery health.

Battery Life & Charging

The ROG Phone 9 Pro houses a substantial 6000mAh battery, representing a meaningful increase over its predecessor’s 5500mAh capacity. This larger battery directly translates to extended usage time across all scenarios, but gaming performance sees the most significant benefits.

Real-world battery testing reveals impressive endurance figures. Gaming sessions with demanding titles average 8-10 hours of continuous play, depending on graphics settings and display brightness. Video streaming extends to 16-18 hours, while social media and web browsing can stretch beyond 20 hours of active use.

Standby performance also impresses, with minimal battery drain during idle periods. The phone consistently loses less than 2% battery overnight, indicating efficient power management when not in active use.

Charging capabilities match the premium positioning with 65W wired charging that takes the battery from empty to 50% in approximately 25 minutes and reaches full charge in just under 90 minutes. While wireless charging supports 15W speeds—sufficient for overnight charging but not particularly fast by current standards.

The bypass charging feature mentioned earlier provides additional value by preventing charging-related heat during gaming sessions. Battery durability improvements include optimized charging curves and temperature monitoring that should maintain battery capacity longer than conventional smartphones.

Cameras & Multimedia

The camera system balances gaming priorities with everyday photography needs. The rear setup includes a 50MP main camera with optical image stabilization, a 13MP ultra-wide lens, and a 5MP macro camera. While not reaching the photography heights of camera-focused flagships, the system delivers solid results across most shooting scenarios.

Main camera performance excels in good lighting conditions, producing sharp images with natural colors and good dynamic range. Low-light photography benefits from computational photography improvements, though it doesn’t quite match the best camera phones in challenging conditions. The ultra-wide camera provides useful versatility for group shots and landscape photography.

The 32MP front-facing camera delivers quality results for streaming, video calls, and social media content. Gaming streamers will appreciate the camera’s ability to maintain good image quality even under the varying lighting conditions common in gaming setups.

Video capabilities extend to 8K recording at 30fps on the main camera, with excellent stabilization for handheld shooting. Gaming content creators benefit from features like simultaneous screen and camera recording, picture-in-picture modes, and real-time streaming integration.

Audio performance stands out as a particular strength. The stereo speaker system delivers powerful, clear sound with impressive bass response for gaming and media consumption. The retained 3.5mm headphone jack supports high-impedance headphones and provides a clean audio signal that audiophiles will appreciate. Advanced Bluetooth codec support ensures high-quality wireless audio for gaming headsets and music listening.

Software & Gaming Features

The ROG Phone 9 Pro runs Android 14 with ASUS’s ROG UI overlay, which strikes a balance between gaming optimization and clean Android experience. ASUS commits to four years of major Android updates and five years of security patches, addressing previous concerns about long-term software support.
