Display Comparison

While both devices utilize a 4nm process, the display specifications aren't provided. However, given the Honor 300 Pro's flagship positioning, it likely features an LTPO panel for adaptive refresh rates, potentially offering better power efficiency compared to a standard AMOLED panel on the Xiaomi 12 Pro. Bezels are expected to be minimal on both, but Honor often prioritizes screen-to-body ratio in its Pro models. Color accuracy is likely excellent on both, but the Honor 300 Pro may benefit from newer color calibration techniques.

Camera Comparison

Camera details are absent, but both phones are expected to feature multi-camera systems. The Honor 300 Pro, being a newer device, likely benefits from advancements in image processing algorithms and potentially larger sensor sizes. The Xiaomi 12 Pro’s Dimensity 9000+ ISP is capable, but the Snapdragon 8 Gen 3’s ISP in the Honor 300 Pro offers improved noise reduction and dynamic range. Without specific sensor details, it’s difficult to make a definitive judgment, but the Honor 300 Pro likely has an edge in image quality due to its newer processing capabilities.

Performance

The core difference lies in the chipsets. The Honor 300 Pro’s Snapdragon 8 Gen 3, built on a 4nm process, features a Cortex-X4 prime core clocked at 3.0 GHz, offering a significant architectural advantage over the Xiaomi 12 Pro’s Dimensity 9000+ and its Cortex-X2 core at 3.20 GHz. While the Dimensity 9000+ boasts a slightly higher clock speed on its prime core, the Snapdragon 8 Gen 3’s newer architecture and improved efficiency translate to better sustained performance and thermal management. The Snapdragon 8 Gen 3’s combination of Cortex-A720 and A520 cores also provides a more balanced performance profile than the Dimensity 9000+'s A710 and A510 cores. The Honor 300 Pro will likely exhibit less throttling under prolonged heavy loads.

Battery Life

The Honor 300 Pro’s charging capabilities are a standout feature. Its 100W wired charging can reportedly add 59% charge in just 15 minutes, and the 80W wireless charging adds 39% in the same timeframe. The Xiaomi 12 Pro’s 67W wired charging, while supporting PD3.0 and QC4, is significantly slower. While battery capacity isn’t specified for either device, the Honor 300 Pro’s faster charging mitigates concerns about a potentially smaller battery. The inclusion of 5W reverse wired and wireless charging on the Honor 300 Pro adds further convenience.

Buying Guide

Buy the Honor 300 Pro if you prioritize peak performance for gaming, content creation, or demanding applications, and if rapid charging – both wired and wireless – is a key requirement. Buy the Xiaomi 12 Pro (Dimensity) if you're seeking a still-capable flagship experience at a potentially lower price point, and aren't as concerned with having the absolute latest processor or fastest charging speeds. The Xiaomi 12 Pro represents a strong value proposition for budget-conscious buyers.

Frequently Asked Questions

❓ Will the Snapdragon 8 Gen 3 in the Honor 300 Pro get noticeably hotter than the Dimensity 9000+ during extended gaming sessions?
While the Snapdragon 8 Gen 3 is more powerful, Qualcomm has focused heavily on thermal efficiency with this generation. The 4nm process and architectural improvements are designed to minimize heat generation and throttling, meaning the Honor 300 Pro is *less* likely to overheat compared to the Xiaomi 12 Pro's Dimensity 9000+ under sustained load.
❓ Does the Honor 300 Pro's 80W wireless charging require a specific charger, and will it work with any Qi-compatible wireless charger?
The Honor 300 Pro's 80W wireless charging requires a compatible Honor wireless charger to achieve those speeds. While it will work with standard Qi wireless chargers, charging speeds will be significantly reduced. Using a standard Qi charger will likely result in charging speeds similar to or slower than the Xiaomi 12 Pro's wired charging.
❓ Is the difference in CPU clock speeds (3.2 GHz Dimensity vs 3.0 GHz Snapdragon) significant in real-world usage?
While the Dimensity 9000+ has a slightly higher peak clock speed, the Snapdragon 8 Gen 3's newer CPU architecture (Cortex-X4) provides a greater performance uplift than a simple clock speed increase. The Snapdragon 8 Gen 3's improved IPC (Instructions Per Clock) and efficiency result in better overall performance, even at a slightly lower clock speed.
