Display Comparison

The Xiaomi 13 Ultra boasts a significantly brighter display (1207 nits vs 637 nits) and likely better color accuracy and viewing angles due to its modern panel technology. While the Mi 9 SE's contrast ratio is nominally 'infinite,' it's unlikely to match the 13 Ultra's real-world performance. The 13 Ultra also likely has a higher resolution and refresh rate.

Camera Comparison

The Xiaomi 13 Ultra's camera system is a flagship-level powerhouse, likely featuring a larger sensor, advanced image processing, and multiple lenses for versatility. The Mi 9 SE's camera is adequate for basic photography, but it simply can't compete with the 13 Ultra's capabilities in terms of detail, dynamic range, and low-light performance.

Performance

The Snapdragon 8 Gen 2 in the 13 Ultra is a monumental upgrade over the Snapdragon 712 in the Mi 9 SE. Expect drastically faster app loading, smoother multitasking, and significantly improved gaming performance on the 13 Ultra. The 13 Ultra's CPU architecture is also far more efficient.

Battery Life

While the Mi 9 SE has a surprisingly high endurance rating (73h), the 13 Ultra's active use score (10:09h) and even higher endurance rating (108h) suggest superior battery optimization and efficiency despite its more powerful components. The 13 Ultra's significantly faster charging (90W wired, 50W wireless) is another major advantage.

Buying Guide

The Xiaomi Mi 9 SE is ideal for budget-conscious users who prioritize a compact size and decent performance for everyday tasks. The Xiaomi 13 Ultra is for photography enthusiasts, power users, and those who demand the latest and greatest technology, regardless of price.
