Display Comparison

Both the Note20 and OnePlus 8 Pro boast 'Infinite' contrast ratios, indicating excellent OLED panels. However, detailed specifications regarding peak brightness and color accuracy are missing. Given OnePlus’s history, the 8 Pro likely features a slightly more color-accurate display tuned for natural visuals. The Note20’s display, while excellent, is often criticized for its relatively small size compared to the 8 Pro’s expansive 6.78-inch panel, making the OnePlus a better choice for media consumption. Both displays feature a 120Hz refresh rate, but the Note20's implementation is adaptive, potentially impacting battery life.

Camera Comparison

Both phones offer capable camera systems, but differ in their approach. While both feature a photo/video focus, detailed sensor information is limited. The OnePlus 8 Pro’s camera system is known for its versatility and natural image processing, while the Note20 leans towards more saturated colors. The absence of detailed sensor specs makes a direct comparison difficult, but the OnePlus 8 Pro’s consistent image quality and wider dynamic range give it a slight edge. The Note20’s video recording capabilities are excellent, but the 8 Pro’s stabilization is also highly regarded.

Performance

The core difference lies in the chipset. The OnePlus 8 Pro consistently utilizes the Qualcomm Snapdragon 865 5G, while the Galaxy Note20 shipped with either the Snapdragon 865+ (USA) or the Exynos 990 (Global). The Snapdragon 865, with its Kryo 585 core clocked at 3.0 GHz, generally outperforms the Exynos 990’s Mongoose M5 cores (2.73 GHz). The Exynos 990 has been known to exhibit thermal throttling under sustained load, impacting gaming performance. Both phones feature 12GB of RAM in certain configurations, ensuring smooth multitasking. The OnePlus 8 Pro’s optimized software and consistent chipset deliver a more reliable and sustained performance advantage.

Battery Life

The OnePlus 8 Pro boasts a 103-hour endurance rating, indicating solid battery life. Its 30W wired charging (50% in 23 minutes) and 30W wireless charging (50% in 30 minutes) are significantly faster than the Note20’s 25W wired and 15W wireless charging. While the Note20’s battery capacity isn’t specified, the faster charging speeds of the OnePlus 8 Pro translate to less downtime. The 3W reverse wireless charging on the OnePlus 8 Pro is also a slight advantage over the Note20’s 4.5W offering, though both are primarily for charging accessories.

Buying Guide

Buy the Samsung Galaxy Note20 if you absolutely need the S Pen for note-taking, sketching, or remote control functionality, and are willing to accept potentially lower performance and slower charging speeds. Buy the OnePlus 8 Pro if you prioritize raw processing power for gaming and demanding applications, value faster charging, and prefer a cleaner, more streamlined Android experience. The OnePlus 8 Pro is the better choice for those seeking maximum performance per dollar.

Frequently Asked Questions

❓ Does the Exynos 990 in the Note20 overheat during extended gaming sessions?

❓ Is the 3W reverse wireless charging on the OnePlus 8 Pro actually useful?
While 3W reverse wireless charging isn't fast, it's sufficient for topping up accessories like wireless earbuds or smartwatches. It's a convenient feature for users who frequently use these devices and don't want to carry extra cables.
❓ Does the OnePlus 8 Pro support 90fps in PUBG Mobile?
Yes, the OnePlus 8 Pro can achieve 90fps in PUBG Mobile with the appropriate graphics settings enabled. The Snapdragon 865’s powerful GPU and the phone’s 120Hz display contribute to a smooth and responsive gaming experience.
❓ Is the S Pen on the Note20 worth the extra cost if I don't take handwritten notes?
Even if you don't primarily use it for handwriting, the S Pen offers unique features like Air Actions for remote control, screen-off memo, and precise photo editing. If these features appeal to you, the S Pen adds value. Otherwise, the OnePlus 8 Pro offers a better performance-to-price ratio.
