Display Comparison

The Samsung Galaxy A30s features a vibrant Super AMOLED display, offering richer colors and deeper blacks compared to the Oppo R7s' likely IPS LCD. While the R7s boasts a high contrast ratio (nominally infinite, 3.964 in sunlight), the A30s' AMOLED technology provides a superior viewing experience overall. The A30s also likely has a higher resolution.

Camera Comparison

The Samsung Galaxy A30s generally has a more versatile camera system, likely including a main lens, ultrawide lens, and depth sensor. While the Oppo R7s' camera is capable, the A30s' newer sensors and image processing algorithms should produce better photos and videos, especially in low light. The A30s also likely offers more shooting modes and features.

Performance

The Samsung Galaxy A30s' Exynos 7904 chipset, built on a 14nm process, is significantly more efficient and powerful than the Oppo R7s' Snapdragon 615 (28nm). The A30s' CPU configuration (2x1.8 GHz Cortex-A73 & 6x1.6 GHz Cortex-A53) offers better performance in both single-core and multi-core tasks. The R7s' Octa-core (4x1.5 GHz Cortex-A53 & 4x1.0 GHz Cortex-A53) feels dated by comparison.

Battery Life

The Oppo R7s shines in this category. Its endurance rating of 73h is exceptional. However, the Samsung Galaxy A30s, despite having a smaller battery capacity, benefits from a more efficient chipset and still provides respectable battery life. The A30s also supports 15W charging, while the R7s offers faster 20W charging, but the overall battery endurance is the R7s' strength.

Buying Guide

Who should buy the Oppo R7s? Users prioritizing extreme battery life above all else and are comfortable with an older device. Who should buy the Samsung Galaxy A30s? Anyone seeking a modern smartphone with a good balance of performance, camera quality, and features at an affordable price.
