Display Comparison

Both devices share a similar contrast ratio of 1324:1, suggesting comparable color reproduction. However, the Realme 6 Pro boasts a measured peak brightness of 421 nits, which will provide better visibility outdoors compared to the Infinix S5 Pro, whose brightness is not specified. The lack of information on the S5 Pro’s panel technology (IPS vs. AMOLED) and refresh rate puts it at a disadvantage, as the 6 Pro likely offers a smoother visual experience.

Camera Comparison

Both phones are listed as having 'Photo / Video' capabilities, but detailed sensor information is limited. The absence of specific details on the Infinix S5 Pro’s camera setup makes a direct comparison difficult. However, given the Realme 6 Pro’s positioning, it likely features a more advanced camera system with features like improved image stabilization and potentially better low-light performance. The Realme 6 Pro’s image signal processor (ISP) within the Snapdragon 720G will also contribute to superior image processing.

Performance

The Realme 6 Pro’s Qualcomm Snapdragon 720G (8nm) is a significant upgrade over the Infinix S5 Pro’s MediaTek Helio P35 (12nm). The 720G utilizes a more efficient 8nm process, resulting in better thermal management and sustained performance. Its CPU configuration – 2x2.3 GHz Kryo 465 Gold & 6x1.8 GHz Kryo 465 Silver – offers a more balanced approach than the S5 Pro’s 4x2.3 GHz Cortex-A53 & 4x1.8 GHz Cortex-A53, leading to faster app loading times and smoother multitasking. The Snapdragon 720G’s Adreno 618 GPU also provides a substantial gaming performance advantage.

Battery Life

Both devices achieve an endurance rating of 107 hours, suggesting similar overall battery life under typical usage. However, the Realme 6 Pro’s 30W wired charging capability, capable of a full charge in just 57 minutes, is a game-changer. The Infinix S5 Pro’s charging speed is not specified, implying a significantly slower charging time. This faster charging allows the Realme 6 Pro to recover quickly, minimizing downtime.

Buying Guide

Buy the Infinix S5 Pro (16+32) if you absolutely need the lowest possible price and your usage is limited to basic tasks like calling, texting, and light social media. Buy the Realme 6 Pro if you prioritize smoother multitasking, gaming, faster charging, and a more responsive overall experience, even if it means spending a bit more.
