Xiaomi 12S
- Significantly faster performance (Snapdragon 8+ Gen 1)
- Faster charging (67W wired, 50W wireless)
- Potentially better camera quality
- Premium build quality
- Higher price
- Potentially shorter battery life compared to 12X
- Can run hotter under heavy load
Xiaomi 12X
- Excellent battery life (105h endurance rating)
- Smooth performance for everyday tasks
- More affordable price
- Premium design
- Less powerful chipset (Snapdragon 870)
- Slower charging speeds
- May struggle with demanding games
Display Comparison
Both phones feature excellent AMOLED displays, likely with similar color accuracy and brightness. The 'Infinite' contrast ratio is a marketing term, but expect deep blacks and vibrant colors. The 12S might have a slightly higher refresh rate (likely 120Hz) for smoother scrolling, while the 12X is likely 90Hz. Resolution is likely to be similar (FHD+).
Camera Comparison
Both phones offer capable camera systems. The 12S likely has a more advanced primary sensor and potentially improved image processing due to the newer chipset. Expect slightly better low-light performance and more detail in photos from the 12S. Both should capture good video quality.
Performance
This is where the 12S shines. The Snapdragon 8+ Gen 1 is a substantial upgrade over the 870 in the 12X. Expect significantly faster app loading, smoother multitasking, and better gaming performance on the 12S. The 12X still offers a smooth experience for everyday tasks, but it won't handle demanding games as well.
Battery Life
The 12X boasts an impressive endurance rating of 105 hours, suggesting superior battery life. While the 12S has faster charging speeds (both wired and wireless), its more power-hungry chipset might result in shorter real-world battery life compared to the 12X.
Buying Guide
The Xiaomi 12S is ideal for power users, gamers, and anyone who demands top-tier performance and the latest technology. The Xiaomi 12X is a great choice for users who prioritize battery life, a smooth experience, and a more budget-friendly price without sacrificing premium design and a good camera.
