Display Comparison
Both the Oppo A5x and Poco M3 Pro 5G share a contrast ratio of 1475:1, suggesting similar visual pop. However, the Poco M3 Pro 5G boasts a measured peak brightness of 536 nits, offering a brighter viewing experience, particularly outdoors. While the Oppo A5x’s display specifications are not provided, the brightness difference is a clear advantage for the Poco. Both displays likely utilize LCD technology, common in this price bracket, and lack high refresh rates, focusing on power efficiency.
Camera Comparison
Both devices list 'Photo / Video' capabilities, but lack specific details. Without sensor size or aperture information, a direct comparison is difficult. It’s reasonable to assume both phones employ a multi-camera setup with a primary sensor and supporting lenses, but the quality will likely depend heavily on software processing. The prevalence of 2MP macro lenses in this segment suggests neither phone prioritizes high-end photography, focusing instead on providing versatile camera options.
Performance
The Oppo A5x’s Mediatek Dimensity 6300 (6nm) represents a generational leap over the Poco M3 Pro 5G’s Dimensity 700 (7nm). The 6nm process node inherently offers improved power efficiency and thermal characteristics. While both chipsets feature an octa-core configuration with 2x Cortex-A76 and 6x Cortex-A55 cores, the A5x’s A76 cores are clocked slightly higher at 2.4 GHz versus 2.2 GHz on the Poco. This translates to a potential performance edge in CPU-intensive tasks. The A5x’s newer architecture should also benefit from improvements in MediaTek’s core design, leading to better overall responsiveness.
Battery Life
The Poco M3 Pro 5G claims an endurance rating of 121 hours, indicating strong battery life. However, the Oppo A5x compensates with significantly faster charging. The A5x supports 45W wired charging, including 33W PPS and 13.5W PD, capable of reaching 50% charge in just 37 minutes. The Poco M3 Pro 5G is limited to 18W charging, a substantial difference. While the Poco may last longer on a single charge, the A5x’s rapid charging mitigates the impact of a potentially smaller battery capacity (not specified).
Buying Guide
Buy the Oppo A5x if you prioritize fast charging speeds and a more modern chipset for potentially better long-term performance and efficiency. This phone is ideal for users who frequently top up their battery throughout the day or need a phone that can handle moderate multitasking without significant slowdown. Buy the Xiaomi Poco M3 Pro 5G if battery endurance is your absolute top priority and you don't mind slower charging. It's a solid option for users who primarily use their phone for basic tasks and want a device that can reliably last a full day on a single charge.
Frequently Asked Questions
❓ Does the Oppo A5x's Dimensity 6300 handle demanding games like Genshin Impact?
While the Dimensity 6300 is a capable chipset, Genshin Impact will likely require reduced graphics settings for a smooth experience. The 6nm process and higher clock speeds offer an advantage over the Dimensity 700, but it's not a gaming-focused processor. Expect playable frame rates at medium settings.
❓ How much slower is the 18W charging on the Poco M3 Pro 5G compared to the Oppo A5x's 45W?
The difference is substantial. The Oppo A5x can reach 50% charge in approximately 37 minutes, while the Poco M3 Pro 5G will take considerably longer – likely over 90 minutes to reach the same level. This makes the A5x much more convenient for quick top-ups.
❓ Is the lack of 5G carrier aggregation on either phone a significant drawback?
For most users in areas with good 5G coverage, the absence of carrier aggregation won't be immediately noticeable. However, in congested areas or when further from a tower, carrier aggregation can significantly improve 5G speeds and stability. Both phones are likely to offer basic 5G connectivity, but won't maximize potential speeds.
