Display Comparison

The Xiaomi 13 Ultra's display shines with a measured peak brightness of 1207 nits, significantly brighter than the Mix 4. While the Mix 4 has a good display, the 13 Ultra's superior brightness and potentially better color accuracy (though not explicitly stated) give it an edge. Both likely feature AMOLED panels with high refresh rates.

Camera Comparison

The Xiaomi 13 Ultra's camera system is a major highlight. It features a more advanced sensor setup, likely including a larger main sensor and improved image processing capabilities. The Mix 4's camera is decent, but it doesn't compete with the 13 Ultra's flagship-level photography performance. Expect better low-light performance, dynamic range, and overall image quality from the 13 Ultra.

Performance

The Snapdragon 8 Gen 2 in the Xiaomi 13 Ultra is a substantial upgrade over the Snapdragon 888+ in the Mix 4. The newer chipset offers improved CPU and GPU performance, resulting in smoother multitasking, faster app loading times, and better gaming experiences. The 13 Ultra's 4nm process also contributes to better power efficiency.

Battery Life

The Xiaomi 13 Ultra demonstrates superior battery endurance, with an active use score of 10:09h and an endurance rating of 108h. The Mix 4, while offering incredibly fast charging (120W wired, 50W wireless), doesn't match the 13 Ultra's longevity. The 13 Ultra also includes reverse wireless charging, a feature absent in the Mix 4.

Buying Guide

The Xiaomi Mix 4 is a good choice for users prioritizing blazing-fast charging speeds and a more compact design. The Xiaomi 13 Ultra is ideal for photography enthusiasts, power users needing top-tier performance, and those who value long battery life and a premium build.
