Display Comparison
Both the OnePlus 7 Pro and Asus ROG Phone II feature excellent displays, but subtle differences exist. The ROG Phone II edges out the OnePlus 7 Pro with a measured peak brightness of 626 nits versus 616 nits, offering slightly better visibility in direct sunlight. Both displays offer a smooth 90Hz refresh rate, but the ROG Phone II’s infinite contrast ratio (nominal) suggests a superior OLED panel capable of deeper blacks. While both lack official HDR certification, the ROG Phone II’s display characteristics are more conducive to a vibrant and immersive viewing experience.
Camera Comparison
Both phones offer capable photo and video recording, but neither excels in this area compared to contemporary flagships. Both feature similar camera setups, focusing on versatility rather than groundbreaking innovation. Analysis is limited by the context data, but the ROG Phone II’s slightly larger sensor (assumed, based on market positioning) likely provides better low-light performance. The focus here isn’t on photographic prowess, but on providing acceptable image quality for casual use.
Performance
The Asus ROG Phone II leverages the Snapdragon 855+, a minor but meaningful upgrade over the OnePlus 7 Pro’s Snapdragon 855. The 855+ features slightly higher clock speeds (2.96 GHz vs 2.84 GHz on the prime core) and improved thermal management. While real-world performance differences are often marginal in everyday tasks, the ROG Phone II demonstrates a sustained performance advantage during prolonged gaming sessions, minimizing throttling. Both devices utilize an octa-core CPU configuration with the same Kryo 485 architecture, but the ROG Phone II’s chipset provides a small but measurable edge.
Battery Life
The most significant difference between these two devices lies in battery life. The Asus ROG Phone II’s 114-hour endurance rating dwarfs the OnePlus 7 Pro’s 85-hour rating. This translates to a substantial real-world advantage, allowing the ROG Phone II to easily last a full day of heavy use, while the OnePlus 7 Pro may require a top-up. Both support 30W wired charging, but the ROG Phone II adds 10W reverse wired charging and Quick Charge 4.0 compatibility, offering greater charging flexibility.
Buying Guide
Buy the OnePlus 7 Pro if you prioritize a sleek design, a more conventional software experience, and a generally more polished daily driver. It’s ideal for users who want a premium phone without the overtly ‘gamer’ aesthetic. Buy the Asus ROG Phone II if you are a serious mobile gamer, or someone who heavily relies on their phone for extended periods away from a charger. The larger battery, enhanced cooling potential, and slightly faster processor make it the clear winner for power users.
