Display Comparison

The Note5 features a 5.7-inch Quad HD (2560 x 1440) Super AMOLED display, offering vibrant colors and sharp details. The A21s has a 6.5-inch HD+ (1600 x 720) display with a 1287:1 contrast ratio. While the A21s has a good contrast ratio, the Note5's higher resolution and AMOLED technology provide a significantly better viewing experience.

Camera Comparison

While the A21s has more lenses, the Note5's image processing was generally considered excellent for its time. Low-light performance is likely better on the A21s due to newer sensor technology.

Performance

The Note5's Exynos 7420 chipset and Octa-core CPU deliver noticeably faster performance than the A21s' Exynos 850. The Note5 handles demanding apps and games with ease, while the A21s is better suited for everyday tasks. The Note5's RAM advantage (4GB vs 3GB) also contributes to smoother multitasking.

Battery Life

The A21s shines in this category. Its endurance rating of 119h is exceptional, significantly outperforming the Note5's battery life. The Note5's 3000mAh battery struggles to keep up with modern usage patterns.
