At first glance, the Asus ROG Phone II screams “gamer.” With angular lines, a bold RGB-lit ROG logo on the back, and copper accents around the camera module, it’s unapologetically designed for enthusiasts. But it’s not just about looks—the phone feels substantial in hand, thanks to its glass sandwich construction and metal frame. Weighing in at 240g, it’s definitely on the heavier side, but that heft translates to a premium, durable feel. The rear also features a customizable RGB lighting zone that syncs with notifications, calls, or games, adding a personalized touch.
One of the design’s smartest features is the side-mounted USB-C port, perfect for horizontal gameplay without cables getting in the way. There’s also a second USB-C port at the bottom for charging while using accessories. The air triggers—ultrasonic sensors on the top edge—are seamlessly integrated, maintaining the phone’s sleek profile while offering console-like controls.
Display: Smooth, Vibrant, and Responsive
The ROG Phone II boasts a 6.59-inch AMOLED display with a 1080 x 2340 resolution. While it may not have the highest pixel density compared to some modern flagships, it more than makes up for it with a buttery-smooth 120Hz refresh rate. This was one of the first phones to offer such a high refresh rate, and the difference in gaming and general usability is immediately noticeable. Scrolling is fluid, animations are crisp, and in fast-paced titles like Call of Duty: Mobile or Asphalt 9, the extra responsiveness gives you a competitive edge.
Color accuracy is another strong suit. With support for HDR10 and a delta-E color accuracy of less than 1, the screen delivers vibrant, true-to-life colors. The 240Hz touch sampling rate ensures that every tap and swipe is registered almost instantaneously, reducing input lag to a bare minimum. Whether you’re gaming or binge-watching, this display is a delight.
Performance: No Compromises, Pure Power
Under the hood, the ROG Phone II is powered by the Qualcomm Snapdragon 855 Plus chipset, paired with up to 12GB of RAM. Even by 2025 standards, this combination holds up remarkably well. In synthetic benchmarks like Geekbench 5, it scores around 3600 multi-core, putting it in the same league as many mid-range 2024 devices. But benchmarks only tell part of the story—where this phone truly shines is in real-world gaming performance.
Games like Genshin Impact and PUBG Mobile run at max settings without breaking a sweat. Frame rates remain consistently high, and thanks to the advanced cooling system—which includes a large vapor chamber and optional AeroActive Cooler accessory—thermal throttling is minimal. I played Genshin Impact for an hour straight, and the phone stayed cool to the touch, maintaining a steady 60fps throughout.
Battery Life: All-Day Gaming, and Then Some
With a massive 6000mAh battery, the ROG Phone II is built to last. In everyday use, it easily delivers two full days of moderate usage. For gaming, you can expect around 8-10 hours of continuous playtime, depending on the title and settings. Even with the 120Hz refresh rate enabled, battery drain is manageable, though switching to 60Hz can extend longevity further if needed.
Charging is equally impressive. The included 30W HyperCharge adapter can take the phone from 0 to 100% in just over an hour. There’s also support for reverse charging, allowing you to use the ROG Phone II as a power bank for other devices—a handy feature for gamers on the go.
Software and Gaming Features: Tailored for Enthusiasts
The phone runs on ROG UI, a custom skin based on Android 9 Pie (upgradable to Android 11). While it may not be the latest OS, the software is optimized for gaming with minimal bloatware. The Armory Crate app serves as a hub for all gaming-related settings, allowing you to customize performance profiles, map air triggers, and monitor system stats in real-time.
One standout feature is the X Mode, which maximizes CPU and RAM allocation for gaming. You can also fine-tune settings like touch sensitivity, network priority, and even block notifications during gameplay. For streamers, there’s built-in support for live streaming directly to platforms like YouTube and Twitch, making it easy to share your gameplay without additional hardware.
Accessories: Expanding the Ecosystem
Asus offers a range of accessories that elevate the ROG Phone II from a great gaming phone to a portable console. The Kunai Gamepad transforms it into a handheld gaming device, while the TwinView Dock adds a second screen for multitasking or immersive gameplay. The AeroActive Cooler not only keeps temperatures down but also adds physical buttons and a passthrough charging port. These accessories are well-designed and integrate seamlessly, though they do add to the overall cost.
Camera: Capable, but Not the Main Attraction
Let’s be honest—if you’re buying a gaming phone, the camera isn’t your top priority. That said, the ROG Phone II’s dual setup (48MP primary + 13MP ultra-wide) is decent for everyday photography. In well-lit conditions, photos are sharp with accurate colors. Low-light performance is acceptable with Night Mode, though it can’t compete with dedicated camera phones like the Google Pixel or iPhone.
Video recording tops out at 4K 60fps, with electronic stabilization that works reasonably well for casual use. For gamers who occasionally snap photos or record clips, it’s more than sufficient. But if photography is a priority, you might want to look elsewhere.
Audio: Immersive and Loud
Audio is another area where the ROG Phone II excels. The dual front-facing speakers deliver rich, clear sound with impressive stereo separation. They’re among the loudest on any smartphone, making gameplay immersive even without headphones. For private listening, the 3.5mm headphone jack (a rarity these days) supports high-resolution audio and comes with DAC support for enhanced clarity.
