Display Comparison
Both devices share an 'Infinite' (nominal) contrast ratio, suggesting typical IPS LCD characteristics. However, detailed display specs like peak brightness and color gamut coverage are missing. Given the Poco X4 Pro 5G’s positioning, it likely benefits from a slightly more refined panel. The absence of high refresh rate information on either device suggests a standard 60Hz experience, which is common in this price bracket. Bezels are likely comparable, focusing on maximizing screen real estate within their respective budgets.
Camera Comparison
Both phones feature 'Photo / Video' capabilities, but specific details are lacking. Without sensor size or aperture information, a direct comparison is difficult. However, the market positioning suggests the Poco X4 Pro 5G likely incorporates a more capable primary sensor. The inclusion of features like Optical Image Stabilization (OIS) – common in Poco’s mid-range offerings – would further differentiate it. The 2MP macro cameras often found on both devices are generally of limited utility, offering minimal detail and image quality.
Performance
The core difference lies in the chipsets. The Poco X4 Pro 5G’s Qualcomm Snapdragon 695 5G (6nm) boasts a more modern architecture and a smaller fabrication process than the Infinix Note 12i’s MediaTek Helio G85 (12nm). This translates to improved power efficiency and sustained performance. The Snapdragon 695’s Kryo 660 Gold cores, clocked at 2.2 GHz, offer a slight clock speed advantage over the Helio G85’s Cortex-A75 cores (2.0 GHz). While both are octa-core CPUs, the Snapdragon’s architecture and process node provide a clear edge in demanding tasks and gaming. The 6nm process also means less heat generation, reducing the likelihood of performance throttling during extended use.
Battery Life
Both devices achieve an endurance rating of 119 hours, indicating similar overall battery life under typical usage. However, the charging speeds are drastically different. The Poco X4 Pro 5G’s 67W wired charging, supporting PD3.0 and QC3, is a significant advantage, achieving 70% charge in 22 minutes and 100% in 41 minutes. The Infinix Note 12i’s 33W charging is considerably slower. This means the Poco X4 Pro 5G can quickly top up its battery, minimizing downtime, even if the actual battery capacity isn’t significantly larger.
Buying Guide
Buy the Infinix Note 12i if you prioritize a lower upfront cost and are primarily focused on basic smartphone tasks like calling, texting, and light social media use. Buy the Xiaomi Poco X4 Pro 5G if you value smoother multitasking, occasional gaming, faster charging speeds, and the benefits of a more power-efficient 5G chipset, even if it means spending a bit more.
