vivo iQOO 9
- Slightly faster 50% charge time
- Higher battery endurance rating (though marginal)
- Potentially lower price point (depending on region)
- Older Snapdragon 888+ chipset
- Less efficient 5nm process
- Dimmer display
Xiaomi 12T Pro
- More powerful Snapdragon 8+ Gen 1 chipset
- Brighter display for better outdoor visibility
- More efficient 4nm process for sustained performance
- Slightly slower full charge time
- Lower battery endurance rating
- Potentially higher price point
Display Comparison
The Xiaomi 12T Pro boasts a significantly brighter display, reaching 913 nits measured, compared to the iQOO 9’s 749 nits. This translates to better visibility outdoors under direct sunlight. Both displays share an 'Infinite' (nominal) contrast ratio, typical of AMOLED panels. While neither specification details refresh rate or panel technology (LTPO), the brightness difference is a clear win for the 12T Pro, benefiting users who consume a lot of media outdoors or in brightly lit environments.
Camera Comparison
Both phones are listed as having 'Photo / Video' capabilities, lacking specific details. Without sensor size, aperture, or OIS information, a direct comparison is impossible. However, given Xiaomi’s history of focusing on camera features, it’s reasonable to assume the 12T Pro may offer more advanced image processing algorithms and potentially a more versatile camera system. The absence of detail suggests neither phone is a standout camera performer in this segment.
Performance
The core difference lies in the chipsets. The Xiaomi 12T Pro utilizes the Snapdragon 8+ Gen 1 (4nm), while the iQOO 9 features the Snapdragon 888+ 5G (5nm). The 8+ Gen 1’s smaller 4nm node provides a substantial efficiency advantage, leading to less heat generation under load. This is reflected in the CPU architecture: the 12T Pro’s Cortex-X2 core clocks higher at 3.19 GHz versus the iQOO 9’s 2.99 GHz Cortex-X1. The newer Cortex-A710 cores in the 12T Pro also offer improved performance per watt. Gamers and power users will notice the difference in sustained performance, with less throttling on the 12T Pro.
Battery Life
The iQOO 9 has an endurance rating of 105 hours, while the Xiaomi 12T Pro scores 91 hours. However, this doesn’t tell the whole story. Both support 120W wired charging, but the 12T Pro reaches 100% in 19 minutes, while the iQOO 9 takes 18 minutes. The iQOO 9 gets to 50% in 6 minutes, slightly faster than the 12T Pro. The iQOO 9’s slightly better endurance is likely due to the less power-hungry chipset, but the difference is offset by the 12T Pro’s more efficient processor and brighter display.
Buying Guide
Buy the vivo iQOO 9 if you prioritize the absolute fastest charging speeds and are a casual user who doesn't heavily tax the processor with demanding games or applications. Buy the Xiaomi 12T Pro if you value sustained performance during gaming, video editing, or multitasking, and appreciate a brighter, more vibrant display. The 12T Pro is the better choice for power users.
