Display Comparison
Both devices feature similar display technologies, though specific details like peak brightness aren't provided. The S20+ 5G likely benefits from Samsung’s advancements in display calibration and potentially higher peak brightness. However, without specific nit ratings, it’s difficult to definitively declare a winner. Both are expected to offer vibrant colors and excellent viewing angles, typical of Samsung’s AMOLED panels. The S20+ 5G’s slightly larger screen size may appeal to users who consume more media.
Camera Comparison
While both phones likely share similar image processing algorithms, the S20+ 5G likely has an edge in overall camera quality due to its potentially larger sensor and more advanced features. Details on sensor sizes are missing, but the S20+ 5G’s flagship status suggests a more sophisticated camera system. The Quantum 2’s camera is competent, but it doesn’t appear to offer any significant advantages over the S20+ 5G. The inclusion of a 2MP macro camera on the S20+ 5G is largely a marketing gimmick and offers limited practical benefit.
Performance
The core difference lies in the chipsets. The Quantum 2 utilizes the Snapdragon 855+, a 7nm processor known for its stability and solid performance. The S20+ 5G, however, comes in two variants: the Exynos 990 (globally) and the Snapdragon 865 (US). The Snapdragon 865 offers a clear performance advantage over both the Exynos 990 and the 855+ due to its newer architecture and 7nm+ process. The Exynos 990, while powerful, has been known to suffer from thermal throttling under sustained load, impacting long gaming sessions. The Quantum 2’s 855+ avoids this issue, offering consistent performance. The S20+ 5G (Snapdragon variant) benefits from faster RAM speeds (LPDDR5) compared to the Quantum 2 (likely LPDDR4X), further enhancing its performance.
Battery Life
Both devices support 25W wired charging, offering similar charging speeds. However, the S20+ 5G adds 15W wireless charging (Qi standard) and 4.5W reverse wireless charging, providing greater versatility. While battery capacity isn’t specified, the S20+ 5G’s larger size suggests a potentially larger battery. The Snapdragon 855+ in the Quantum 2 is more power-efficient than the Exynos 990, potentially offsetting the S20+ 5G’s larger battery capacity. Real-world battery life will depend heavily on usage patterns.
Buying Guide
Buy the Samsung Galaxy Quantum 2 if you need enhanced security features thanks to the QRNG chipset and prefer a consistently performing device without worrying about potential throttling issues. Buy the Samsung Galaxy S20+ 5G if you prioritize faster 5G connectivity (particularly in the US with the Snapdragon 865 variant), wireless charging, and are comfortable with the possibility of occasional performance dips under sustained load.
