Display Comparison

Both phones feature excellent AMOLED displays, but the Mi 11 Ultra's 943 nits peak brightness is slightly higher than the Mix 4's reported brightness (though specific Mix 4 brightness data is less readily available). The Mi 11 Ultra's infinite contrast ratio also contributes to a more vibrant and immersive viewing experience. The Mix 4's display likely has a higher refresh rate, offering smoother scrolling and animations.

Camera Comparison

The Mi 11 Ultra's camera system is arguably its standout feature. Its massive 108MP main sensor, periscope telephoto lens, and ultrawide lens deliver exceptional image quality and versatility. While the Mix 4 has a capable camera, it doesn't quite match the Mi 11 Ultra's overall photographic prowess. The Mi 11 Ultra excels in low-light conditions and offers impressive zoom capabilities.

Performance

The Mix 4's Snapdragon 888+ offers a slight performance advantage over the Mi 11 Ultra's Snapdragon 888, particularly in CPU-intensive tasks. Both phones handle everyday use and demanding games with ease, but the Mix 4's extra processing power can be noticeable in certain scenarios. Both have ample RAM for multitasking.

Battery Life

The Mi 11 Ultra's endurance rating of 95h is significantly better than the Mix 4's, suggesting superior battery life. While the Mix 4's charging speeds are unmatched, the Mi 11 Ultra can last much longer between charges. This is a crucial factor for users who prioritize all-day battery performance.

Buying Guide

The Xiaomi Mix 4 is ideal for power users who prioritize charging speed and a slightly more modern processor. The Mi 11 Ultra is perfect for photography enthusiasts and those who value long battery life and a stunning display.

Frequently Asked Questions
