Display Comparison

The Xiaomi 12S Ultra takes the display crown with its higher peak brightness (1065 nits vs 1000 nits estimated for the Pro) and an impressive infinite contrast ratio. While both phones feature excellent AMOLED panels with 120Hz refresh rates, the Ultra's superior brightness makes it more visible in direct sunlight. The Pro's slightly smaller size might be preferred by some.

Camera Comparison

This is where the 12S Ultra truly shines. It features a significantly larger main sensor (likely a 1-inch type sensor) and a more versatile camera system overall. The Pro's camera is still excellent, but the Ultra offers superior image quality, especially in low light, and greater zoom capabilities. Video recording capabilities are also likely to be enhanced on the Ultra.

Performance

Both devices are powered by the Snapdragon 8+ Gen 1, ensuring blazing-fast performance for any task. Real-world performance differences will be minimal, with both handling demanding games and multitasking with ease. Cooling solutions might vary slightly, potentially impacting sustained performance under heavy load, but this is difficult to quantify without testing.

Battery Life

The 12S Ultra boasts an exceptional endurance rating of 93 hours, significantly outperforming the 12S Pro. While the Pro's 120W wired charging is incredibly fast (19 minutes to 100%), the Ultra's larger battery provides longer usage time between charges. The wireless charging speeds are comparable.

Buying Guide

The Xiaomi 12S Pro is ideal for users who want a powerful, fast-charging phone with a premium feel and don't prioritize having the absolute best camera system. The Xiaomi 12S Ultra is perfect for photography lovers, content creators, and those who need exceptional battery life and a larger, more immersive display.
