Display Comparison
The Galaxy S23's display is a major upgrade. Its 1198 nits peak brightness blows the Zenfone 6's 455 nits out of the water, making it far more visible in sunlight. The 'Infinite' contrast ratio on the S23 is also a significant advantage over the Zenfone 6's 1201:1. While both offer good color accuracy, the S23's AMOLED technology provides richer colors and deeper blacks.
Camera Comparison
While the Zenfone 6's camera is capable, the Galaxy S23's camera system is far more advanced. The S23 benefits from improved image processing, better low-light performance, and more versatile shooting options. Samsung's software optimizations also contribute to a more polished camera experience.
Performance
The Snapdragon 8 Gen 2 in the Galaxy S23 is a generational leap over the Snapdragon 855 in the Zenfone 6. Expect significantly faster app loading times, smoother multitasking, and better performance in demanding games. The S23's newer CPU architecture and 4nm process also contribute to improved power efficiency.
Battery Life
Both phones offer impressive battery life, with the Zenfone 6 boasting an endurance rating of 112h and the S23 at 101h. However, the S23's faster 25W charging and wireless charging capabilities provide a significant advantage in terms of convenience.
Buying Guide
The Asus Zenfone 6 is ideal for budget-conscious users who prioritize battery life and don't need the absolute latest features. The Samsung Galaxy S23 is perfect for those who demand top-tier performance, a stunning display, and a premium camera experience, and are willing to pay for it.
