Display Comparison

The S23 Ultra's 1274 nits peak brightness and infinite contrast ratio utterly eclipse the Mi Mix 2S's display. The S23 Ultra's Dynamic AMOLED 2X panel offers vibrant colors, deep blacks, and exceptional outdoor visibility, a level of quality the Mi Mix 2S simply can't match. The S23 Ultra also has a higher resolution and refresh rate.

Camera Comparison

The S23 Ultra's camera system is in a different league. It offers significantly higher resolution sensors, improved image processing, and advanced features like Space Zoom. The Mi Mix 2S's camera was decent for its time, but it's no match for the S23 Ultra's versatility and image quality.

Performance

The Snapdragon 8 Gen 2 in the S23 Ultra is a significant leap over the Snapdragon 845 in the Mi Mix 2S. Expect dramatically faster app loading, smoother multitasking, and superior gaming performance on the S23 Ultra. The S23 Ultra's newer architecture and fabrication process contribute to both speed and efficiency.

Battery Life

The S23 Ultra's endurance rating of 126h is far superior to the Mi Mix 2S's 59h. The S23 Ultra also features faster charging (45W wired vs 18W) and wireless charging (15W vs 7.5W), along with reverse wireless charging, a feature absent in the Mi Mix 2S.

Buying Guide

The Xiaomi Mi Mix 2S is only suitable for budget-conscious users seeking a nostalgic experience or a very basic smartphone. The Samsung Galaxy S23 Ultra is for anyone who wants the best Android experience, top-tier camera capabilities, and long-lasting performance – if you're willing to pay the premium.
