Display Comparison

Both phones feature excellent AMOLED displays with vibrant colors and smooth 120Hz refresh rates. The Xiaomi 12 has a slightly higher measured peak brightness of 896 nits, while the 12S's display is generally well-regarded. The Xiaomi 12's infinite contrast ratio is a nominal specification and doesn't necessarily translate to a significantly better viewing experience in real-world use. Overall, display performance is very close.

Camera Comparison

Both phones offer capable camera systems, but the 12S is generally considered to have a slight edge. The 12S often features a Sony IMX707 main sensor, known for its excellent image quality. While both phones capture good photos and videos, the 12S's image processing and low-light performance are often slightly better. Specific camera configurations varied by region, so results can differ.

Performance

This is where the Xiaomi 12S truly shines. The Snapdragon 8+ Gen 1 offers a noticeable performance boost over the Snapdragon 8 Gen 1 in the Xiaomi 12. The 8+ Gen 1's improved efficiency results in less throttling during extended gaming sessions and better overall sustained performance. Both phones handle everyday tasks with ease, but the 12S is the clear winner for demanding applications.

Battery Life

The Xiaomi 12 holds a slight advantage in battery life, boasting an impressive endurance rating of 82 hours. The 12S, while still offering good battery life, doesn't quite match the 12's longevity. However, the 12S's faster charging speeds (67W wired vs 39 min for the 12) help to mitigate this difference.

Buying Guide

The Xiaomi 12S is ideal for power users, gamers, and those who prioritize performance and efficient cooling. The Xiaomi 12 remains a great option for budget-conscious buyers who still want a premium experience with excellent battery life and a vibrant display.
