Xiaomi Mi 4s
- Better Battery Life
- Superior Sunlight Display
- More Modern Chipset
- Faster Charging (QC2)
- Potentially slightly slower single-core performance than Mi 3
Xiaomi Mi 3
- Slightly Faster CPU Clock Speed

- Older Chipset
Display Comparison
Both phones feature a 5-inch display, but the Mi 4s takes a slight lead. Its contrast ratio is marginally better at 975:1 compared to the Mi 3's 907:1. More significantly, the Mi 4s boasts a significantly better sunlight readability score of 2.095 versus the Mi 3's 2.001, making it easier to view outdoors.
Camera Comparison
While both phones offer 'Photo / Video' capabilities, detailed camera comparisons are difficult without specific sensor and lens information. Generally, the Mi 4s's newer chipset likely provides better image processing capabilities, resulting in slightly improved photo and video quality. However, both cameras are considered adequate for their time.
Performance
The Mi 3 has a quad-core 2.3 GHz Krait 400 CPU, which initially felt faster. However, the Mi 4s's hexa-core Snapdragon 808 (4x1.4 GHz Cortex-A53 & 2x1.8 GHz Cortex-A57) offers a more balanced and efficient performance profile, especially in multitasking and modern apps. The 20nm process on the 808 is also more efficient than the Mi 3's 28nm Snapdragon 800.
Battery Life
The Mi 4s secures a clear win in battery life, boasting an endurance rating of 75h compared to the Mi 3's 66h. This translates to noticeably longer usage between charges, a significant advantage for daily use.
Buying Guide
The Xiaomi Mi 4s is ideal for users seeking a balance of performance, battery life, and display quality on a budget. The Mi 3 might appeal to those prioritizing raw CPU speed and a slightly more compact design, but its age shows in other areas.
Frequently Asked Questions
❓ Is the Xiaomi Mi 4s still worth buying in [current year]?
While both phones are aging, the Mi 4s's better battery life and display make it a slightly more viable option if you're on a very tight budget and can find one in good condition. However, consider newer budget smartphones for a better overall experience.
❓ Which phone is more likely to receive software updates?
