Realme 9 Pro+
- Superior battery life (117h endurance)
- More affordable price point (likely)
- Balanced feature set
- Slower charging speed (60W)
- Less powerful chipset (Dimensity 920)
Xiaomi 12T Pro
- Blazing-fast 120W charging (19 min to full)
- Powerful Snapdragon 8+ Gen 1 chipset
- Brighter display (913 nits)
- Shorter battery life (91h endurance)
- Potentially higher price
Display Comparison
The Xiaomi 12T Pro’s display is a clear standout with a measured peak brightness of 913 nits, significantly brighter than the Realme 9 Pro+'s 613 nits. This translates to superior visibility outdoors under direct sunlight. While both feature similar resolutions, the Xiaomi 12T Pro’s ‘Infinite’ (nominal) contrast ratio suggests a superior panel capable of deeper blacks. The Realme 9 Pro+ doesn’t specify contrast ratio, implying a standard IPS-like panel. The brighter display of the 12T Pro will be more enjoyable for media consumption and gaming.
Camera Comparison
Both phones offer photo and video capabilities, but detailed sensor information is lacking. Without specifics, it’s difficult to make a definitive judgment. However, given Xiaomi’s history of camera innovation, the 12T Pro likely benefits from more advanced image processing algorithms. The Realme 9 Pro+ may focus on a more natural color profile, while the Xiaomi 12T Pro could lean towards more vibrant, social media-ready images. The absence of detailed camera specs makes this a tie, pending further testing.
Performance
The core difference lies in the chipsets. The Xiaomi 12T Pro’s Snapdragon 8+ Gen 1 (4nm) is a substantial upgrade over the Realme 9 Pro+'s Dimensity 920 (6nm). The Snapdragon 8+ Gen 1 features a Cortex-X2 prime core clocked at 3.19 GHz, alongside Cortex-A710 performance cores, offering significantly higher single-core and multi-core performance. The 4nm process node also contributes to better thermal efficiency, reducing throttling during sustained workloads like gaming. While the Dimensity 920 is capable, it will struggle to match the 12T Pro in demanding tasks. The Xiaomi 12T Pro is the better choice for gamers and power users.
Battery Life
The Realme 9 Pro+ boasts an endurance rating of 117 hours, while the Xiaomi 12T Pro manages 91 hours. This indicates the Realme 9 Pro+ offers significantly better battery life. However, the Xiaomi 12T Pro compensates with its blazing-fast 120W charging, achieving a full charge in just 19 minutes, compared to the Realme 9 Pro+'s 44 minutes with its 60W charging. This trade-off is crucial: the 12T Pro sacrifices some endurance for unparalleled charging speed, while the 9 Pro+ prioritizes longevity.
Buying Guide
Buy the Realme 9 Pro+ if you need a phone that will comfortably last a full day and beyond, even with moderate to heavy use, and you value a more balanced feature set. Buy the Xiaomi 12T Pro if you prioritize gaming performance, demand the fastest possible charging speeds, and are willing to trade some battery life for that extra power.
