Display Comparison

Both phones feature Super AMOLED displays, known for their vibrant colors and deep blacks. The Galaxy S III boasts a slightly higher contrast ratio in sunlight (3.419:1 vs 2.832:1), suggesting better visibility outdoors. Both have a 'nominal' infinite contrast ratio, which is a marketing term and not a measurable value. Screen sizes are similar, with the S III having a slightly larger 4.8-inch display compared to the S II's 4.3-inch.

Camera Comparison

While both phones offer Photo/Video capabilities, the Galaxy S III generally produced slightly better image quality, particularly in low-light conditions. The S III's camera also benefited from Samsung's image processing algorithms, which were more refined at the time. Specific megapixel counts are not provided, but the S III's image processing gave it an edge.

Performance

The Galaxy S III's Exynos 4412 Quad-core processor is the clear winner here. Its quad-core architecture and 1.4 GHz clock speed provide a noticeable performance boost over the Galaxy S II's dual-core 1.2 GHz Exynos 4210. Expect smoother multitasking and faster app loading times on the S III.

Battery Life

The Galaxy S III's endurance rating of 50h significantly surpasses the Galaxy S II's 40h. This translates to longer screen-on time and overall usage between charges, making the S III a more practical choice for extended use.

Buying Guide

The Galaxy S III is ideal for Android enthusiasts seeking a capable, albeit older, device with a bit more power. The Galaxy S II might appeal to those on an extremely tight budget or specifically looking for a smaller, more compact phone, but be prepared for compromises in performance.
