Samsung Galaxy Note20 Ultra 5G

  • Integrated S Pen for productivity and creativity
  • Bright and vibrant display
  • Samsung ecosystem integration

  • Exynos 990 can suffer from thermal throttling
  • Slower charging speeds
  • Older chipset compared to the Mi 11 Ultra

Xiaomi Mi 11 Ultra

  • Significantly faster charging (wired and wireless)
  • More powerful Snapdragon 888 processor
  • Superior camera performance (especially in low light)

  • Lacks S Pen functionality
  • Larger and heavier design
  • Xiaomi’s MIUI software can be polarizing

Display Comparison

Both devices feature 'Infinite' contrast ratio displays, but differ in peak brightness. The Note20 Ultra achieves 1024 nits, while the Mi 11 Ultra peaks at 943 nits. While the Note20 Ultra is brighter on paper, real-world viewing experiences are similar, and both offer excellent visibility. Neither device specifies refresh rate, but both are assumed to be 120Hz, a standard for flagships of this era. The Note20 Ultra’s display is geared towards content consumption and S Pen interaction, while the Mi 11 Ultra’s display serves as a vibrant viewfinder for its advanced camera system.

Camera Comparison

Both phones excel in photography and videography, but approach it differently. While detailed sensor specs are not provided, the Mi 11 Ultra’s camera system is widely regarded as superior, particularly in low-light conditions. The Snapdragon 888’s image signal processor (ISP) contributes to better noise reduction and dynamic range. The Note20 Ultra’s camera is still capable, but the Mi 11 Ultra’s advanced processing and potentially larger sensors (based on market reputation) give it an edge. Both phones offer video recording capabilities, but the Mi 11 Ultra’s stabilization and overall image quality are generally considered superior.

Performance

The Xiaomi Mi 11 Ultra’s Snapdragon 888 (5nm) represents a significant leap over the Samsung Galaxy Note20 Ultra’s Exynos 990 (7nm+) or Snapdragon 865 5G+ (7nm+). The Snapdragon 888’s Cortex-X1 prime core delivers superior single-core performance, crucial for responsive app launches and smooth multitasking. The Exynos 990, particularly the global variant, has been known to exhibit thermal throttling under sustained load, impacting long gaming sessions. The Mi 11 Ultra’s more efficient 5nm process mitigates this issue. While both phones offer ample RAM, the Mi 11 Ultra’s chipset provides a more future-proof platform.

Battery Life

The Mi 11 Ultra boasts a 95-hour endurance rating, slightly exceeding the Note20 Ultra’s 88-hour rating. However, the real differentiator is charging speed. The Mi 11 Ultra supports 67W wired charging (0-100% in 36 minutes) and 67W wireless charging (0-100% in 39 minutes), dwarfing the Note20 Ultra’s 25W wired, 15W wireless, and 4.5W reverse wireless capabilities. This means the Mi 11 Ultra can be topped up much faster, minimizing downtime. The slightly larger battery capacity combined with the efficient Snapdragon 888 contributes to the Mi 11 Ultra’s longer endurance.

Buying Guide

Buy the Samsung Galaxy Note20 Ultra 5G if you absolutely require the S Pen for note-taking, sketching, or remote control functionality and are invested in the Samsung ecosystem. Buy the Xiaomi Mi 11 Ultra if you prioritize camera performance, blazing-fast charging speeds, and a more powerful processor for demanding tasks, and don't need the S Pen.

Frequently Asked Questions

❓ Does the Exynos 990 in the Note20 Ultra overheat during prolonged gaming sessions?
Yes, the Exynos 990 variant of the Note20 Ultra is known to experience thermal throttling under sustained load, such as during extended gaming. This can lead to reduced performance and frame rate drops. The Snapdragon 865+ variant (available in the USA) handles heat better, but still isn't as efficient as the Mi 11 Ultra's Snapdragon 888.
❓ How does the 67W wireless charging on the Mi 11 Ultra compare to the Note20 Ultra's 15W wireless charging in real-world use?
The difference is substantial. The Mi 11 Ultra can fully charge wirelessly in approximately 39 minutes, while the Note20 Ultra takes significantly longer – over an hour and a half. This makes the Mi 11 Ultra much more convenient for users who frequently rely on wireless charging.
❓ Is the S Pen on the Note20 Ultra worth the trade-off in processing power and charging speed?
That depends entirely on your usage. If you are a frequent note-taker, artist, or rely on the S Pen for productivity tasks, then it may be worth the trade-off. However, for the average user, the Mi 11 Ultra’s superior performance and charging capabilities offer a more compelling overall experience.
❓ Does the Mi 11 Ultra's camera perform well in low-light conditions?
Yes, the Mi 11 Ultra is renowned for its exceptional low-light performance. Its larger sensor (though specific size is not provided) and advanced image processing algorithms capture bright, detailed images with minimal noise, even in very dark environments.
