Display Comparison
Both devices feature displays with an 'Infinite' (nominal) contrast ratio, suggesting excellent black levels. However, the Asus ROG Phone II distinguishes itself with a measured peak brightness of 626 nits, significantly exceeding what’s available on the OnePlus 7T Pro. This brighter display translates to better visibility in direct sunlight, a crucial benefit for outdoor gaming. While both likely utilize AMOLED technology, the ROG Phone II’s higher brightness provides a more vibrant and usable experience in various lighting conditions. The lack of refresh rate data for both phones means we can't compare smoothness, but both were considered high-end for their time.
Camera Comparison
Both phones offer 'Photo / Video' capabilities, but detailed camera specifications are absent. Given the ROG Phone II’s gaming focus, it’s reasonable to assume the OnePlus 7T Pro may have prioritized camera quality slightly more. However, without sensor size, aperture, or image processing details, a definitive comparison is impossible. The absence of information suggests neither phone was a standout in the camera department compared to other flagships of the era.
Performance
Both the OnePlus 7T Pro and Asus ROG Phone II are powered by the Qualcomm SM8150 Snapdragon 855+ (7 nm) chipset, featuring an identical octa-core CPU configuration. This means raw processing power will be nearly indistinguishable between the two. However, the ROG Phone II’s larger chassis and more robust cooling system likely allow it to sustain peak performance for longer periods, mitigating potential thermal throttling during extended gaming sessions. While both utilize the same chipset, the ROG Phone II’s thermal design gives it an edge in sustained performance.
Battery Life
The Asus ROG Phone II boasts a clear advantage in battery endurance, achieving a rating of 114 hours compared to the OnePlus 7T Pro’s 100 hours. This 14-hour difference translates to a noticeable improvement in real-world usage, particularly for power users and gamers. Both support 30W wired charging, but the ROG Phone II adds the convenience of 10W reverse wired charging and Quick Charge 4 (QC4) compatibility, allowing it to charge other devices. This versatility is a significant benefit for users who frequently travel or rely on multiple devices.
Buying Guide
Buy the OnePlus 7T Pro if you need a sleek, refined flagship with a smooth user experience and prioritize a more understated design. It’s ideal for users who value a balance of features and don’t require the specialized gaming extras. Buy the Asus ROG Phone II ZS660KL if you prioritize extended gaming sessions, demand maximum battery life, and appreciate features like reverse wireless charging and a brighter display. This phone is built for power users and mobile gaming enthusiasts.
