Display Comparison

The Zenfone 7 Pro boasts a display capable of reaching 741 nits of peak brightness, providing good visibility outdoors. While the ROG Phone 5s’s display specs aren’t provided, ROG phones typically prioritize high refresh rates over absolute peak brightness. The Zenfone 7 Pro’s infinite (nominal) contrast ratio suggests a strong OLED panel. The ROG Phone 5s, being a gaming phone, likely features a higher refresh rate panel, crucial for smooth gameplay, but this comes at the cost of potentially higher power consumption. The Zenfone 7 Pro’s smaller size also contributes to a higher pixel density, potentially resulting in a sharper image.

Camera Comparison

Both phones feature capable camera systems, but their approaches differ. The Zenfone 7 Pro’s camera is described as focusing on both photo and video, suggesting a well-rounded experience. Without specific sensor details, it’s difficult to make a direct comparison. However, the Zenfone 7 Pro’s emphasis on photography suggests a focus on image quality and versatility. The ROG Phone 5s, while having a camera, is primarily geared towards gaming, so its camera system is likely less prioritized. The ROG Phone 5s’s camera is likely tuned for quick snapshots and social media sharing, while the Zenfone 7 Pro aims for more detailed and professional-looking results.

Performance

The ROG Phone 5s’s Snapdragon 888+ 5G (5nm) represents a significant leap over the Zenfone 7 Pro’s Snapdragon 865 (7nm+). The 888+ features the newer Cortex-X1 prime core clocked at 2.99 GHz, offering substantial performance gains over the 865’s Cortex-A77. The 5nm process node also improves thermal efficiency, reducing throttling during sustained workloads. While the Zenfone 7 Pro’s CPU configuration (1x3.10 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, 4x1.80 GHz Cortex-A55) is respectable, it cannot match the raw power of the ROG Phone 5s. The ROG Phone 5s is designed for sustained peak performance, while the Zenfone 7 Pro prioritizes a balance between performance and efficiency.

Battery Life

The Zenfone 7 Pro achieves an impressive endurance rating of 99 hours, indicating excellent battery life. It supports 30W wired charging, reaching 60% in 34 minutes and 100% in 93 minutes. The ROG Phone 5s, with its 65W wired charging, significantly outperforms the Zenfone 7 Pro, achieving 70% in 30 minutes and 100% in 52 minutes. While the ROG Phone 5s’s battery capacity isn’t specified, its faster charging and gaming-focused design suggest it’s optimized for quick top-ups during gaming sessions. The Zenfone 7 Pro’s longer endurance is better suited for users who prioritize all-day battery life without frequent charging.

Buying Guide

Buy the Asus Zenfone 7 Pro if you need a compact, high-quality camera system in a relatively understated package, and value long battery life. It's ideal for photographers and everyday users who don't require extreme gaming performance. Buy the Asus ROG Phone 5s if you prioritize mobile gaming, demanding applications, and the fastest possible charging. Its larger size and more aggressive design are trade-offs for its superior performance capabilities.

Frequently Asked Questions

❓ Does the Snapdragon 888+ in the ROG Phone 5s suffer from overheating during prolonged gaming sessions?
While the Snapdragon 888+ is a powerful chip, it was known to run hot under sustained load. However, the ROG Phone 5s incorporates advanced cooling solutions, including a vapor chamber and multiple heat sinks, designed to mitigate thermal throttling and maintain stable performance during extended gaming sessions. These cooling features are a key differentiator for the ROG Phone 5s.
❓ How does the reverse wired charging compare between the Zenfone 7 Pro and ROG Phone 5s for topping up accessories?
Both phones offer reverse wired charging, but the ROG Phone 5s’s 10W output is significantly lower than the Zenfone 7 Pro’s. This means the Zenfone 7 Pro will charge accessories faster, making it a more practical option for topping up earbuds or other small devices on the go.
❓ Is the Zenfone 7 Pro still a good choice for mobile gaming, despite its older chipset?
The Zenfone 7 Pro can handle most mobile games at reasonable settings, but it won't deliver the same level of performance or graphical fidelity as the ROG Phone 5s. The Snapdragon 865 is capable, but the 888+ offers a substantial performance boost, especially in demanding titles. If gaming is a priority, the ROG Phone 5s is the better choice.
