Display Comparison

The Asus ROG Phone 3 boasts a significantly brighter display at 719 nits compared to the Xperia 5 II’s 600 nits, offering improved visibility in direct sunlight. While both feature an 'Infinite' contrast ratio (typical for OLED panels), the ROG Phone 3’s 120Hz refresh rate provides a smoother gaming experience, a feature absent on the Xperia 5 II’s 60Hz panel. The ROG Phone 3’s larger 6.59-inch screen also provides a more immersive experience, while the Xperia 5 II’s 6.1-inch display prioritizes pocketability.

Camera Comparison

Both devices offer capable camera systems, but their approaches differ. While both are listed as having Photo/Video capabilities, detailed sensor information is missing. Given Sony’s expertise in camera technology, the Xperia 5 II likely prioritizes image quality and color accuracy, leveraging Sony’s image processing algorithms. The ROG Phone 3, while capable, likely focuses more on versatility and features geared towards content creation for social media. Without specific sensor details, it’s difficult to definitively declare a winner, but Sony’s brand reputation suggests a slight edge in overall image quality.

Performance

Both phones utilize the Qualcomm Snapdragon 865 5G chipset, but the ROG Phone 3 steps up to the Snapdragon 865+ variant. This translates to a slightly higher CPU clock speed – 3.10 GHz on the ROG Phone 3 versus 2.84 GHz on the Xperia 5 II – offering a marginal performance boost in CPU-intensive tasks. Both share the same CPU core configuration (1x Cortex-A77 at higher clock, 3x Cortex-A77, 4x Cortex-A55). The ROG Phone 3’s larger size and more robust cooling system likely allow it to sustain peak performance for longer periods, mitigating thermal throttling during extended gaming sessions. Both devices feature 8GB of RAM, but the ROG Phone 3’s optimized software and hardware configuration are geared towards maximizing gaming performance.

Battery Life

The Asus ROG Phone 3 delivers a clear advantage in battery endurance, boasting a 120-hour rating compared to the Xperia 5 II’s 102-hour rating. This is likely due to a larger battery capacity (not specified in the data) and the ROG Phone 3’s more aggressive power management features. Furthermore, the ROG Phone 3 supports 30W wired charging with Quick Charge 4 and Power Delivery 3.0, significantly faster than the Xperia 5 II’s 21W charging. The ROG Phone 3 also offers 10W reverse wired charging, a feature absent on the Xperia 5 II.

Buying Guide

Buy the Sony Xperia 5 II if you need a premium smartphone that easily fits in one hand, prioritizes a balanced multimedia experience with a strong camera, and values a more understated design. Buy the Asus ROG Phone 3 if you prefer maximum gaming performance, require extended battery life for marathon sessions, and appreciate features like AirTriggers and a high refresh rate display, even if it means a larger, more aggressive aesthetic.

Frequently Asked Questions

❓ Does the Snapdragon 865+ in the ROG Phone 3 offer a noticeable performance difference in real-world gaming compared to the Snapdragon 865 in the Xperia 5 II?
While the difference isn't massive, the Snapdragon 865+ in the ROG Phone 3 provides a slight performance edge, particularly in sustained gaming sessions. The higher clock speed and improved thermal management allow it to maintain peak performance for longer, reducing the likelihood of frame drops and throttling.
❓ How much does the larger size of the ROG Phone 3 impact usability and comfort?
The ROG Phone 3 is significantly larger and heavier than the Xperia 5 II. This can make it difficult to use one-handed and less comfortable to carry in a pocket. However, the larger size also allows for a larger battery and more effective cooling, which are crucial for gaming.
❓ Is the 21W charging on the Xperia 5 II slow compared to the 30W charging on the ROG Phone 3?
Yes, the 30W charging on the ROG Phone 3 is considerably faster. While 21W is still respectable, it will take significantly longer to fully charge the Xperia 5 II. The ROG Phone 3 can reach 50% charge in a shorter timeframe, offering a quicker top-up for gaming sessions.
❓ Given the lack of detailed camera specs, what should a photography enthusiast prioritize between these two phones?
If photography is a high priority, the Sony Xperia 5 II is likely the better choice, leveraging Sony’s established expertise in camera technology and image processing. While the ROG Phone 3 is capable, it’s geared more towards versatile content creation rather than pure image quality.
