Display Comparison
Both devices utilize 7nm+ fabrication processes, suggesting similar efficiency in panel driving. While specific display specs (resolution, refresh rate) aren't provided, both would have been flagship-grade for 2020. The S20+ likely benefits from Samsung's display expertise, potentially offering slightly better color accuracy and outdoor visibility. However, the Ace2's display technology isn't specified, making a definitive comparison difficult. Bezels were likely comparable, reflecting the design trends of the time.
Camera Comparison
Without detailed sensor specifications, a precise camera comparison is challenging. However, the S20+ likely boasts a more sophisticated image processing pipeline, leveraging Samsung's years of camera expertise. The Ace2's camera system is less documented, suggesting a focus on hardware rather than computational photography. The S20+'s OIS (Optical Image Stabilization) is likely more advanced, resulting in sharper images and smoother video recording. The presence of a 2MP macro camera on either device is largely inconsequential; these sensors typically offer limited detail and are often better avoided.
Performance
The chipset is a critical differentiator. The Oppo Ace2 consistently features the Qualcomm Snapdragon 865 5G, built on a 7nm+ process. The Galaxy S20+ 5G, however, shipped with either the Exynos 990 (globally) or the Snapdragon 865 (USA). The Exynos 990, also 7nm+, generally lagged behind the Snapdragon 865 in sustained performance and thermal efficiency. The Snapdragon 865 in the Ace2, with its Cortex-A77 cores, offers a performance edge, particularly in demanding tasks like gaming. The CPU architecture difference – the S20+'s global Exynos using Mongoose M5 cores versus the Ace2's A77 cores – translates to real-world differences in multi-core performance and power consumption. The Ace2's Snapdragon 865 benefits from Qualcomm's optimized GPU, potentially delivering higher frame rates in graphically intensive games.
Battery Life
The battery capacity isn't specified for either device, but the charging speeds are a defining factor. The Oppo Ace2's 65W wired charging is revolutionary, achieving a 100% charge in just 30 minutes. Its 40W wireless charging (56 minutes to full) is equally impressive. The Galaxy S20+ 5G's 25W wired charging (PD3.0) and 15W wireless charging (Qi) are significantly slower. While a larger battery capacity on the S20+ might offer slightly longer runtime, the Ace2's rapid charging mitigates this advantage, allowing for quick top-ups throughout the day. The Ace2 also includes 10W reverse wireless charging, a feature the S20+ offers at a slower 4.5W.
Buying Guide
Buy the Oppo Ace2 if you need incredibly fast charging, both wired and wireless, and value raw performance from the Snapdragon 865. It's ideal for power users who frequently top up their phones throughout the day. Buy the Samsung Galaxy S20+ 5G if you prefer a more established brand with a refined software experience, a potentially better camera algorithm (depending on region), and integration with the Samsung ecosystem of devices. It's a better choice for those who prioritize a holistic user experience over sheer charging speed.
