Samsung Galaxy S20+

  • More compact design for easier one-handed use.
  • Potentially lower price point, especially for base configurations.
  • 8K video recording capability.

  • Exynos chipset can suffer from thermal throttling.
  • Slower charging speeds (wired and wireless).
  • Shorter battery life compared to the OnePlus 8 Pro.

OnePlus 8 Pro

  • Consistent performance with Snapdragon 865.
  • Faster charging speeds (wired and wireless).
  • Longer battery life for all-day use.

  • Larger size may be less comfortable for some users.
  • Higher initial price point (though decreasing).
  • Color science leans towards a more natural look, which some may prefer less.

Display Comparison

Both the Galaxy S20+ and OnePlus 8 Pro boast 'Infinite' contrast ratios, typical of high-end AMOLED panels. However, the S20+ achieves a measured peak brightness of 797 nits, while the OnePlus 8 Pro’s brightness isn’t specified, but is likely comparable. Both feature 120Hz refresh rates, but the OnePlus 8 Pro’s implementation is generally considered smoother due to its adaptive refresh rate technology. The S20+’s smaller 6.7-inch display versus the 8 Pro’s 6.78-inch screen offers a slightly higher pixel density, potentially resulting in marginally sharper visuals, though this difference is subtle to the naked eye.

Camera Comparison

Both phones offer versatile camera systems, but differ in their approach. While both are capable of excellent photo and video, the OnePlus 8 Pro’s camera system benefits from a larger main sensor and a dedicated color filter camera for improved color accuracy. The S20+’s camera processing tends towards more saturated colors, while the 8 Pro aims for a more natural look. Both phones offer capable video recording, but the S20+’s 8K video recording capability is a notable advantage, though its practical use is limited by storage and editing requirements. The inclusion of a 2MP macro camera on both devices is largely a marketing gimmick, offering minimal benefit over standard close-up shots.

Performance

The core performance difference lies in the chipset. The OnePlus 8 Pro exclusively ships with the Qualcomm Snapdragon 865 5G (7nm+), featuring an Octa-core CPU (1x2.84 GHz Cortex-A77 & 3x2.42 GHz Cortex-A77 & 4x1.80 GHz Cortex-A55). The Galaxy S20+, however, utilizes either the Exynos 990 (7nm+) globally or the Snapdragon 865 in the USA. The Exynos 990, with its Mongoose M5 cores, historically exhibited more thermal throttling under sustained load compared to the Snapdragon 865. Both phones feature 8GB or 12GB of RAM, but the OnePlus 8 Pro’s 12GB configuration is more readily available, providing a slight edge in multitasking. The Snapdragon 865’s more efficient architecture translates to better sustained performance and potentially longer gaming sessions.

Battery Life

The OnePlus 8 Pro boasts a significant advantage in battery endurance, achieving a 103-hour rating compared to the S20+'s 87-hour rating. This is coupled with significantly faster charging: the 8 Pro supports 30W wired charging (50% in 23 minutes) and 30W wireless charging (50% in 30 minutes), while the S20+ maxes out at 25W wired and 15W wireless. The 8 Pro also offers 3W reverse wireless charging, while the S20+ provides 4.5W. This means the OnePlus 8 Pro can be topped up much quicker and offers more convenient wireless charging options.

Buying Guide

Buy the Samsung Galaxy S20+ if you prioritize a slightly more compact design and are comfortable with the potential for regional chipset variations. It's ideal for users who don't heavily rely on wireless charging or demand the absolute longest battery life. Buy the OnePlus 8 Pro if you value consistent performance thanks to the Snapdragon 865, faster charging speeds (both wired and wireless), and a larger battery capacity, making it perfect for power users and those who frequently travel.

Frequently Asked Questions

❓ Does the Exynos 990 in the Galaxy S20+ overheat during demanding tasks like gaming?
Yes, the Exynos 990 variant of the S20+ is known to exhibit thermal throttling under sustained load, particularly during prolonged gaming sessions or video recording. This can lead to reduced performance and potentially shorter battery life compared to the Snapdragon 865 version.
❓ Is the 30W wireless charging on the OnePlus 8 Pro truly faster than the S20+'s 15W wireless charging?
Absolutely. The OnePlus 8 Pro’s 30W wireless charging is significantly faster, reaching 50% charge in approximately 30 minutes, while the S20+ takes considerably longer with its 15W wireless charging. This makes the 8 Pro much more convenient for users who prefer wireless charging.
❓ How does the image processing differ between the S20+ and the 8 Pro?
The Samsung Galaxy S20+ tends to produce images with more saturated colors and boosted contrast, aiming for a visually appealing look straight out of the camera. The OnePlus 8 Pro, on the other hand, prioritizes color accuracy and a more natural image processing style, offering greater flexibility for post-processing.
❓ Is the 8GB of RAM in the base models of both phones sufficient for modern multitasking?
Yes, 8GB of RAM is generally sufficient for most users and everyday multitasking. However, the OnePlus 8 Pro’s availability in a 12GB configuration provides a noticeable advantage for power users who frequently run multiple demanding apps simultaneously.
