  • Less established brand recognition in some markets
  • No integrated stylus support

Display Comparison

The Xiaomi Mi 10 Pro boasts a brighter display, reaching a measured 858 nits, compared to the Note20's unspecified peak brightness. While both offer excellent viewing experiences, the Mi 10 Pro’s higher peak brightness translates to better visibility under direct sunlight. Both displays feature an infinite (nominal) contrast ratio, suggesting deep blacks. The Note20’s display technology isn’t specified, but given Samsung’s expertise, it likely utilizes a high-quality AMOLED panel. However, the Mi 10 Pro’s brightness advantage is a clear win for outdoor usability.

Camera Comparison

Both phones are equipped with capable camera systems, but details are limited to 'Photo / Video' for both. The Mi 10 Pro likely benefits from Xiaomi’s image processing algorithms, focusing on vibrant colors and detail. Without specific sensor size or aperture information, it’s difficult to definitively declare a winner. However, the Mi 10 Pro’s reputation for strong camera performance, particularly in low light, suggests a slight edge. The Note20’s camera is competent, but the lack of detailed specifications hinders a precise comparison. We can safely ignore the likely inclusion of 2MP macro lenses on both devices, as their utility is minimal.

Performance

The performance landscape is complex. The Mi 10 Pro consistently utilizes the Qualcomm Snapdragon 865 5G (7nm+), while the Note20 splits paths – the Exynos 990 (7nm+) for global markets and the Snapdragon 865 5G+ (7nm+) for the USA. The Snapdragon 865+ in the US Note20 offers a slight CPU clock speed advantage (3.0 GHz Kryo 585 vs 2.84 GHz Cortex-A77 on the Mi 10 Pro), but the core architecture is similar. The Exynos 990, however, has historically faced criticism for thermal throttling under sustained load, potentially impacting long gaming sessions. The Mi 10 Pro’s consistent Snapdragon chipset provides a more predictable and sustained performance profile. Both devices utilize LPDDR5 RAM, ensuring fast memory access.

Battery Life

Both the Note20 5G and Mi 10 Pro 5G achieve an endurance rating of 101 hours, indicating similar overall battery life. However, the charging speeds are drastically different. The Mi 10 Pro supports 50W wired charging with PD3.0, allowing for a significantly faster 0-100% charge time compared to the Note20’s 25W wired charging. The Mi 10 Pro also offers 30W wireless charging, dwarfing the Note20’s 15W wireless charging. While both offer reverse wireless charging, the Mi 10 Pro’s 5W output is less powerful than the Note20’s 4.5W. The Mi 10 Pro’s charging speed is a major advantage for users who prioritize quick top-ups.

Buying Guide

Buy the Samsung Galaxy Note20 5G if you absolutely need the S Pen for note-taking, sketching, or remote control functionality, and value Samsung's software ecosystem. Buy the Xiaomi Mi 10 Pro 5G if you prioritize faster charging, consistent performance from the Snapdragon 865, and a brighter display, all while potentially saving money.

Frequently Asked Questions

❓ Does the Exynos 990 in the global Note20 5G overheat during extended gaming sessions?
The Exynos 990 has been known to exhibit thermal throttling under sustained load, particularly during graphically intensive games. While Samsung implemented cooling solutions, the Snapdragon 865 in the US version and the Mi 10 Pro generally maintain more consistent performance over longer periods.
❓ How much faster is the 50W charging on the Mi 10 Pro compared to the Note20's 25W charging?
The Mi 10 Pro’s 50W charging can fully charge the battery in approximately 35-40 minutes, while the Note20’s 25W charging typically takes around 1 hour and 15 minutes to reach 100%. This represents a significant time saving for users who frequently need to quickly top up their battery.
❓ Is the S Pen on the Note20 5G worth the extra cost if I don't regularly take notes or draw?
If you don't anticipate using the S Pen's core features – handwriting recognition, sketching, Air Actions – the added cost of the Note20 5G may not be justified. The Mi 10 Pro offers comparable performance and features at a potentially lower price point.
❓ Does the Mi 10 Pro support 90fps gaming?
The Snapdragon 865 in the Mi 10 Pro is capable of running many popular games at high frame rates, including 60fps and potentially 90fps depending on the game's optimization. However, achieving consistently high frame rates may require adjusting graphics settings.
