Display Comparison

Both phones feature Super AMOLED displays, offering vibrant colors and deep blacks. The Galaxy S III boasts a slightly larger 4.8-inch screen compared to the S II's 4.3-inch display. While both have a nominal 'infinite' contrast ratio, the sunlight readability is reported as 3.419:1 for both, suggesting similar outdoor visibility. The S III's slightly larger size and potentially improved panel technology give it a marginal edge.

Camera Comparison

Both phones feature Photo/Video capabilities, but the Galaxy S III generally produces slightly better image quality, particularly in low-light conditions. The S III's processing algorithms and potentially improved sensor contribute to more detailed and vibrant photos. Video recording capabilities are comparable.

Performance

The Galaxy S III's Exynos 4412 quad-core processor is a significant upgrade over the Galaxy S II's dual-core OMAP 4430. This translates to noticeably faster app loading times, smoother multitasking, and better overall responsiveness. The S III handles demanding games and applications with greater ease.

Battery Life

Both phones are reported to have an endurance rating of 50 hours. However, real-world battery life depends heavily on usage patterns. The S III's more efficient quad-core processor and slightly larger battery capacity *could* provide a marginal advantage in certain scenarios, but the reported endurance rating suggests similar performance.

Buying Guide

The Samsung Galaxy S II is a good option for budget-conscious users seeking a reliable, albeit older, Android experience. The Galaxy S III is ideal for those wanting a more powerful and feature-rich phone, even if it's a legacy device. Consider your budget and desired performance level.
