Display Comparison

The Samsung Galaxy S20+ 5G boasts a more visually striking display, though the Xperia 5 II isn’t far behind. While both utilize 7nm+ fabrication, the S20+’s panel likely achieves a higher contrast ratio than the Xperia 5 II’s ‘Infinite’ (nominal) rating suggests. Sony’s display peaks at 600 nits, which is respectable, but falls short of the S20+'s likely higher peak brightness. Both support PD3.0, but the S20+ adds 15W wireless charging and 4.5W reverse wireless, features absent on the Xperia 5 II. The S20+’s 120Hz refresh rate (not specified for the 5 II) would provide smoother scrolling and gaming, though it impacts battery life.

Camera Comparison

Both devices offer capable camera systems, but cater to different shooting styles. While both are listed as having Photo/Video capabilities, the Xperia 5 II emphasizes professional video features, including a dedicated shutter button and real-time tracking autofocus. The S20+ likely benefits from Samsung’s advanced image processing algorithms, known for vibrant colors and strong dynamic range. Sensor sizes and lens apertures are not specified, making a direct comparison difficult, but the Xperia 5 II’s focus on manual controls and video features sets it apart. The inclusion of a 2MP macro camera on the S20+ is largely a marketing gimmick and offers limited practical benefit.

Performance

Both phones are powered by the Qualcomm Snapdragon 865 5G (in the US version of the S20+), but the global S20+ uses the Exynos 990. The Snapdragon 865 offers more consistent performance and better thermal management than the Exynos 990, which has been known to throttle under sustained load. The Xperia 5 II’s CPU configuration (1x2.84 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, 4x1.80 GHz Cortex-A55) is identical to the US Snapdragon S20+’s, suggesting similar raw processing power. However, Sony’s thermal design and software optimization could influence real-world performance. Both phones feature 8GB of RAM, but the type (LPDDR5 vs LPDDR4x) isn’t specified, impacting memory bandwidth.

Battery Life

The Sony Xperia 5 II boasts an impressive endurance rating of 102 hours, significantly exceeding what’s typically seen in flagship smartphones. This is likely due to a combination of its 3600mAh battery (not specified, but typical for the device) and Sony’s power management optimizations. The Samsung Galaxy S20+ 5G, while offering faster 25W wired charging (compared to the Xperia 5 II’s 21W), likely has a shorter battery life. The S20+’s inclusion of 15W wireless charging and reverse wireless charging adds convenience, but at the cost of efficiency. The Xperia 5 II’s 30-minute 50% charge time is competitive, but the S20+ can achieve a full charge faster.

Buying Guide

Buy the Sony Xperia 5 II if you need exceptional battery endurance (102h rating), a dedicated camera shutter button for professional photography/videography, and a clean, near-stock Android experience. Buy the Samsung Galaxy S20+ 5G if you prefer a brighter, more color-accurate display, faster charging speeds, and the broader feature set of Samsung’s One UI, particularly if you’re already invested in the Samsung ecosystem.

Frequently Asked Questions

❓ Does the Exynos 990 in the global S20+ 5G overheat during demanding tasks like gaming?
Yes, the Exynos 990 variant of the S20+ 5G is known to experience thermal throttling under sustained load, particularly during gaming. This can lead to reduced performance and frame rate drops. The Snapdragon 865 variant does not suffer from this issue to the same extent.
❓ Is the 2MP macro camera on the Samsung Galaxy S20+ 5G actually useful?
Generally, no. 2MP macro cameras often lack the detail and clarity needed for truly impressive macro photography. The image quality is typically subpar compared to using the main sensor with digital zoom. It's largely a marketing feature with limited practical benefit.
❓ Does the Sony Xperia 5 II support 90fps or 120fps video recording?
Yes, the Sony Xperia 5 II is specifically designed for videographers and supports high frame rate recording up to 120fps at 1080p, allowing for smooth slow-motion footage. It also offers advanced video features like HDR video and Cinema Pro mode.
❓ Which phone is better for mobile gaming, considering thermal performance?
The Sony Xperia 5 II, with its Snapdragon 865 and potentially better thermal management, is likely the better choice for sustained gaming sessions. The Exynos 990 in the global S20+ 5G is prone to throttling, which can negatively impact gaming performance.
