Display Comparison
The Motorola Moto G 5G boasts a contrast ratio of 1419:1, significantly exceeding the Samsung Galaxy A51 5G’s nominal ‘Infinite’ contrast ratio. While ‘Infinite’ often indicates an OLED panel, the A51 5G utilizes an LCD, resulting in less true black levels. The A51 5G compensates with a measured peak brightness of 642 nits, outshining the Moto G 5G’s 484 nits, making it more readable under direct sunlight. However, the superior contrast of the Moto G 5G contributes to a more immersive viewing experience in typical conditions.
Camera Comparison
Both phones feature a 'Photo / Video' camera setup, but lack detailed sensor information in the provided data. Given the market positioning, it’s likely both rely on multi-camera systems with a primary sensor for detailed shots and auxiliary lenses for ultra-wide or macro photography. Without specific sensor size or aperture data, it’s difficult to definitively assess image quality. However, Qualcomm’s image signal processor (ISP) within the Snapdragon 750G often delivers superior image processing, particularly in low-light conditions, compared to the Exynos 980’s ISP.
Performance
Both devices employ 8nm process technology, with the Samsung A51 5G featuring the Exynos 980 and the Motorola Moto G 5G utilizing the Qualcomm Snapdragon 750G. Both CPUs share a similar octa-core configuration (2x2.2 GHz and 6x1.8 GHz), suggesting comparable multi-core performance. However, the Snapdragon 750G is generally regarded as more efficient and offers a more mature software optimization, potentially leading to better sustained performance and reduced thermal throttling during extended gaming sessions. While both chipsets support 5G, the Snapdragon 750G’s modem is known for broader 5G band compatibility.
Battery Life
The Motorola Moto G 5G dominates in battery endurance with a remarkable 131-hour rating, dwarfing the Samsung Galaxy A51 5G’s 90-hour rating. This substantial difference suggests the Moto G 5G’s combination of a more efficient chipset and optimized power management yields significantly longer usage times. Furthermore, the Moto G 5G supports 20W wired charging, enabling faster replenishment compared to the A51 5G’s 15W charging. This means less time tethered to an outlet and more time enjoying the phone’s features.
Buying Guide
Buy the Samsung Galaxy A51 5G if you need a brighter display for outdoor visibility and prefer the Samsung One UI software experience. Buy the Motorola Moto G 5G if you prioritize exceptional battery life, faster 20W charging, and a more streamlined Android experience. The Moto G 5G is ideal for users who frequently travel or rely heavily on their phone throughout the day.
