Display Comparison
Neither device's display specifications are provided, so a direct comparison is limited. However, given the Y31 Pro's positioning, it likely features a high refresh rate AMOLED panel, common in its price bracket. The Note 12 Pro 5G, historically, has favored LCD panels in this series, potentially resulting in lower contrast and less vibrant colors. Bezels are likely comparable, but the Y31 Pro may benefit from slightly more advanced display calibration due to vivo's focus on image quality.
Camera Comparison
Without specific camera specs, analysis is limited. However, vivo typically emphasizes camera capabilities, suggesting the Y31 Pro may feature a more sophisticated image processing pipeline and potentially a larger primary sensor. The Note 12 Pro 5G likely focuses on providing a versatile camera setup at a competitive price, but may fall short in low-light performance compared to the Y31 Pro. The presence or absence of Optical Image Stabilization (OIS) on either device would be a crucial differentiator, but is unknown.
Performance
The core difference lies in the chipsets. The vivo Y31 Pro’s Mediatek Dimensity 7300 (4nm) boasts a more modern architecture with four Cortex-A78 cores clocked at 2.5 GHz, compared to the Infinix Note 12 Pro 5G’s Dimensity 810 (6nm) which uses two Cortex-A76 cores at 2.4 GHz. The 4nm fabrication process of the Dimensity 7300 translates to significantly improved power efficiency and thermal performance, allowing for sustained peak performance during extended gaming sessions. While the Note 12 Pro 5G’s Dimensity 810 is still capable, it will likely exhibit more throttling under heavy load. The Y31 Pro's CPU configuration also suggests a performance edge in multi-threaded tasks.
Battery Life
The vivo Y31 Pro’s 44W wired charging is a clear advantage over the Infinix Note 12 Pro 5G’s 33W charging. Vivo claims a 50% charge in 40 minutes, while the Note 12 Pro 5G will take considerably longer to reach full capacity. While battery capacity isn't specified for either device, the Dimensity 7300’s superior efficiency in the Y31 Pro could offset a potentially smaller battery size, resulting in comparable real-world battery life. The Y31 Pro also offers reverse wired charging, a feature absent in the Note 12 Pro 5G.
Buying Guide
Buy the vivo Y31 Pro if you need a phone capable of handling demanding games and applications with less thermal throttling, and if faster charging is a priority. Buy the Infinix Note 12 Pro 5G if you prefer a more affordable option and your usage primarily revolves around everyday tasks like social media, browsing, and light gaming, and you don't mind slightly slower charging speeds.
Frequently Asked Questions
❓ Will the Dimensity 7300 in the vivo Y31 Pro handle demanding games like Genshin Impact at high settings?
The Dimensity 7300's architecture and 4nm process are well-suited for Genshin Impact. While you may need to adjust settings slightly for optimal frame rates, the Y31 Pro should provide a smoother and more consistent gaming experience than the Note 12 Pro 5G, which will likely struggle with sustained performance.
❓ How much slower is the charging on the Infinix Note 12 Pro 5G compared to the vivo Y31 Pro?
The vivo Y31 Pro charges at 44W and reaches 50% in approximately 40 minutes. The Infinix Note 12 Pro 5G’s 33W charging will take significantly longer – likely over an hour to reach 50%, and well over two hours for a full charge. This difference is substantial for users who frequently need to top up their battery quickly.
❓ Does the Dimensity 810 in the Infinix Note 12 Pro 5G get hot during prolonged gaming sessions?
The Dimensity 810, being a 6nm chip, is more prone to thermal throttling than the 4nm Dimensity 7300. Expect noticeable heat buildup and potential performance drops during extended gaming sessions on the Note 12 Pro 5G. The Y31 Pro will manage heat more effectively.
