Display Comparison

The Mi 4c boasts a higher nominal contrast ratio (1609:1) compared to the Mi 4s (975:1). However, the Mi 4s shines in direct sunlight with a significantly better contrast ratio of 2.095 versus the Mi 4c's 2.574. This suggests the Mi 4s offers better outdoor readability, a crucial factor for many users.

Camera Comparison

Camera performance on both devices is comparable, relying on a 13MP rear camera and a 5MP front camera. Image quality will be adequate for casual photography, but don't expect flagship-level results. Low-light performance will be a weakness on both.

Performance

Both phones are powered by the same Qualcomm Snapdragon 808 chipset and Hexa-core CPU. Performance will be largely similar in everyday tasks and most apps. However, the Mi 4s might exhibit slightly better sustained performance due to its potentially more efficient thermal management, though this is difficult to confirm definitively without testing.

Battery Life

This is where the Mi 4s truly stands out. It offers a significantly better endurance rating of 75h compared to the Mi 4c's 52h. This translates to considerably longer battery life for the Mi 4s, making it a more practical choice for users who need their phone to last throughout the day.

Buying Guide

Who should buy the Xiaomi Mi 4s? Users prioritizing longer battery life and better outdoor visibility. Who should buy the Xiaomi Mi 4c? Those seeking a slightly more compact device, though the battery performance is a notable drawback. Considering their age, both are best suited for budget-conscious users or those needing a secondary device.
