  • Shorter battery life (98h endurance)
  • Dimmer display (650 nits) may struggle in sunlight

Display Comparison

Both phones feature displays with an 'Infinite' (nominal) contrast ratio, suggesting excellent black levels. However, the Asus ROG Phone 5 boasts a significantly brighter panel at 806 nits measured, compared to the Realme GT 5G’s 650 nits. This translates to better visibility under direct sunlight. While both likely utilize high refresh rate panels (not explicitly stated, but standard for this segment), the ROG Phone 5’s higher peak brightness is a tangible advantage for outdoor use and HDR content consumption. The lack of LTPO technology on either device means refresh rate scaling isn't as power efficient as on newer flagships.

Camera Comparison

Both phones list 'Photo / Video' capabilities, but lack specific details. Given the market positioning, the ROG Phone 5 likely prioritizes image quality and video stabilization for content creation during gaming streams. The Realme GT 5G, while capable, may lean towards a more social media-focused camera experience. Without sensor size or aperture information, it’s difficult to make a definitive judgment. It's reasonable to assume both utilize a multi-camera setup, but the ROG Phone 5 might offer more advanced software features tailored to gamers.

Performance

Both devices are powered by the Qualcomm SM8350 Snapdragon 888 5G (5 nm) chipset, featuring the same CPU configuration: an octa-core setup with 1x2.84 GHz Cortex-X1, 3x2.42 GHz Cortex-A78, and 4x1.80 GHz Cortex-A55 cores. Therefore, raw CPU performance will be nearly identical. The key differentiator lies in thermal management. The ROG Phone 5, designed for sustained gaming, likely incorporates a more robust cooling solution, potentially mitigating thermal throttling during extended, demanding sessions. While RAM configuration isn't specified, the ROG Phone 5's gaming focus suggests a higher probability of faster LPDDR5 RAM, further enhancing performance.

Battery Life

The Asus ROG Phone 5’s endurance rating of 110 hours significantly surpasses the Realme GT 5G’s 98 hours. This difference is crucial for gamers who require extended playtime. While both support 65W wired charging, the ROG Phone 5 takes 52 minutes to reach 100%, while the Realme GT 5G achieves full charge in 35 minutes. This faster charging speed on the Realme GT 5G is a convenience, but the ROG Phone 5’s larger battery capacity provides a more substantial advantage in real-world usage. The inclusion of 10W reverse wired charging on both devices is a minor convenience feature.

Buying Guide

Buy the Asus ROG Phone 5 if you need maximum battery life for extended gaming sessions, prioritize a high-brightness display for outdoor visibility, and value gaming-specific features like AirTriggers. Buy the Realme GT 5G if you prefer a more streamlined design, faster charging speeds, and a potentially lower price point without sacrificing core performance capabilities.

Frequently Asked Questions

❓ Will the Snapdragon 888 in the Realme GT 5G overheat during prolonged gaming sessions?
The Snapdragon 888 is known to generate heat under sustained load. While the Realme GT 5G has cooling, it's likely less robust than the ROG Phone 5's system. Expect some throttling after extended gaming, potentially impacting frame rates. Shorter gaming bursts will be less affected.
❓ Does the Asus ROG Phone 5's AirTriggers offer a significant advantage in gaming?
Yes, the AirTriggers provide customizable shoulder buttons that can be mapped to in-game actions. This allows for more precise control and faster response times, particularly in competitive games. They offer a tangible advantage over traditional touchscreen controls.
❓ How does the charging speed difference impact daily use between the two phones?
While the Realme GT 5G charges 17 minutes faster, the ROG Phone 5's larger battery means you'll likely need to charge less frequently. The convenience of faster charging is offset by the ROG Phone 5's longer-lasting power.
