Xiaomi 12

  • Slightly better endurance rating (82h)
  • 50W Wireless Charging
  • Established Snapdragon ecosystem

  • Prone to thermal throttling under sustained load
  • Snapdragon 8 Gen 1 is less power efficient

  • Superior sustained performance with Dimensity 9000+
  • Improved thermal management
  • Potentially better camera ISP

  • Endurance rating not provided
  • Wireless charging specs unknown

Display Comparison

Both devices feature high-quality displays, but the Xiaomi 12 boasts a measured peak brightness of 896 nits. While the Xiaomi 12 Pro’s display specifications aren’t provided, it’s reasonable to expect similar or slightly improved brightness given its ‘Pro’ designation. Both displays share an infinite (nominal) contrast ratio, suggesting excellent black levels. The absence of refresh rate information for the Pro model means we can't assess potential differences in smoothness, but both likely support high refresh rates common in flagship devices.

Camera Comparison

Both phones are listed as having 'Photo / Video' capabilities, lacking specific details. Given the Pro model’s positioning, it’s reasonable to assume a more advanced camera system, potentially with a larger main sensor or additional features like improved optical image stabilization (OIS). Without sensor size or aperture information, a definitive camera comparison is impossible. However, the Dimensity 9000+'s superior ISP (Image Signal Processor) could contribute to faster image processing and potentially better low-light performance.

Performance

The core differentiator is the chipset. The Xiaomi 12 utilizes the Qualcomm SM8450 Snapdragon 8 Gen 1 (4nm), featuring an octa-core CPU with a prime Cortex-X2 core clocked at 3.00 GHz. The Xiaomi 12 Pro (Dimensity) counters with the MediaTek Dimensity 9000+ (4nm), boasting a slightly faster Cortex-X2 core at 3.20 GHz, alongside higher clock speeds for its Cortex-A710 performance cores (2.85 GHz vs 2.50 GHz). This translates to a tangible performance advantage for the Dimensity 9000+ in sustained workloads, as the 4nm process and architectural optimizations contribute to better thermal efficiency and reduced throttling. Both devices utilize LPDDR5 RAM, but the Pro model's chipset is more efficient at managing it.

Battery Life

The Xiaomi 12 achieves an endurance rating of 82 hours, indicating respectable battery life. The Xiaomi 12 Pro (Dimensity) lacks this endurance rating, making a direct comparison challenging. Both devices share the same 67W wired charging with PD3.0 and QC4 support, achieving a full charge in 39 minutes. The Xiaomi 12 also offers 50W wireless charging (53 minutes to full) and 10W reverse wireless charging, features not explicitly confirmed for the Pro model. The Dimensity 9000+'s efficiency could partially offset any potential battery capacity difference, but the Xiaomi 12’s endurance rating suggests a slight advantage in longevity.

Buying Guide

Buy the Xiaomi 12 if you prioritize a slightly longer endurance rating and are comfortable with potentially more thermal throttling during extended, demanding tasks. Buy the Xiaomi 12 Pro (Dimensity) if you prioritize consistent, high-end performance, especially for gaming and content creation, and value a chipset known for its efficiency.

Frequently Asked Questions

❓ Does the Snapdragon 8 Gen 1 in the Xiaomi 12 overheat during prolonged gaming sessions?
Yes, the Snapdragon 8 Gen 1 is known to generate significant heat under sustained load, leading to thermal throttling. This can result in reduced frame rates and performance dips during extended gaming sessions. The Xiaomi 12 Pro (Dimensity) with its Dimensity 9000+ chipset is significantly better at managing heat and maintaining consistent performance.
❓ Is the difference in CPU clock speeds (3.00 GHz vs 3.20 GHz) between the two chipsets noticeable in everyday use?
While the 200 MHz difference in peak CPU clock speed might not be immediately apparent in basic tasks like browsing or social media, it contributes to a more responsive experience during demanding applications and multitasking. The Dimensity 9000+'s higher clock speeds, combined with its architectural advantages, result in a noticeable performance boost in CPU-intensive workloads.
❓ Does the Xiaomi 12 Pro (Dimensity) support the same 67W wired charging as the Xiaomi 12?
Yes, both the Xiaomi 12 and the Xiaomi 12 Pro (Dimensity) support 67W wired charging with PD3.0 and QC4 compatibility, allowing for a full charge in approximately 39 minutes. However, the Xiaomi 12 also supports 50W wireless charging, a feature not explicitly confirmed for the Pro model.
