Display Comparison

Both phones feature LCD displays, but the vivo S12 Pro likely has a higher resolution and potentially a more vibrant color reproduction due to its higher price point. The Oppo A57s will offer a decent viewing experience for its price range, but don't expect flagship-level visuals. Screen sizes are likely similar, around 6.5-6.6 inches.

Camera Comparison

The vivo S12 Pro is heavily marketed for its selfie camera, and it likely boasts a higher resolution sensor and advanced features like autofocus and portrait mode enhancements. The Oppo A57s will have a capable main camera, but won't match the vivo's selfie prowess. Both likely have multiple rear lenses (wide, macro, depth).

Performance

This is where the vivo S12 Pro truly shines. The Dimensity 1200 chipset is significantly more powerful than the Helio G35 in the Oppo A57s. Expect smoother multitasking, faster app loading times, and better gaming performance on the vivo S12 Pro. The Oppo A57s will handle basic tasks adequately, but will struggle with demanding games or applications.

Battery Life

The Oppo A57s has a slight edge in charging speed with 33W wired charging versus the vivo S12 Pro's 44W. However, battery capacity is likely similar (around 5000mAh), so real-world battery life should be comparable, with the Oppo potentially lasting slightly longer due to the less power-hungry chipset.

Buying Guide

The vivo S12 Pro is ideal for users who prioritize performance, photography (especially selfies), and a premium design. The Oppo A57s is perfect for those on a tight budget who need a reliable phone for everyday tasks and appreciate a long-lasting battery.
