Display Comparison

The Xiaomi Mi 11 Ultra boasts a significantly brighter display, peaking at 943 nits measured, compared to the Note20 Ultra’s unspecified peak brightness (though typically around 800 nits for Samsung flagships of that era). While both likely utilize AMOLED technology, the Mi 11 Ultra’s higher brightness translates to better outdoor visibility. Both displays feature a nominal infinite contrast ratio, typical of AMOLED panels. The Note20 Ultra’s display benefits from Samsung’s well-tuned color science, but the Mi 11 Ultra’s brightness advantage is a clear win for users frequently exposed to direct sunlight.

Camera Comparison

Both phones excel in camera performance, but the Mi 11 Ultra arguably holds an edge. While both are described as having excellent photo/video capabilities, the Mi 11 Ultra’s larger main sensor (spec not provided, but known to be 50MP) and advanced image processing algorithms likely result in superior low-light performance and dynamic range. The Note20 Ultra’s camera system is still highly capable, but the Mi 11 Ultra’s focus on camera innovation is evident. The Note20 Ultra’s strength lies in its versatile zoom capabilities, but the Mi 11 Ultra’s overall image quality is generally considered superior.

Performance

The Xiaomi Mi 11 Ultra’s Snapdragon 888 (5nm) represents a generational leap over the Samsung Galaxy Note20 Ultra’s Exynos 990 (7nm+) or Snapdragon 865+ (7nm+). The 888’s Cortex-X1 prime core offers a substantial performance boost over the Mongoose M5 in the Exynos variant, and even edges out the Kryo 585 in the Snapdragon 865+ version. The 5nm process node also contributes to improved thermal efficiency, potentially mitigating throttling during sustained workloads. While the Note20 Ultra is still capable, the Mi 11 Ultra delivers a smoother and more responsive experience, particularly in demanding games and applications. The Mi 11 Ultra’s GPU also benefits from the newer architecture, offering superior graphics performance.

Battery Life

Both devices achieve an endurance rating of 95 hours, suggesting comparable real-world battery life despite differing charging capabilities. However, the Mi 11 Ultra’s charging prowess is a game-changer. Its 67W wired charging can fully charge the battery in just 36 minutes, and the 67W wireless charging takes only 39 minutes – significantly faster than the Note20 Ultra’s 25W wired, 15W wireless, and 4.5W reverse wireless charging. This rapid charging capability minimizes downtime and provides a substantial convenience advantage for the Mi 11 Ultra.

Buying Guide

Buy the Samsung Galaxy Note20 Ultra if you need a built-in stylus for note-taking, sketching, or precise control, and value the seamless integration with Samsung's DeX desktop experience. Buy the Xiaomi Mi 11 Ultra if you prioritize exceptional camera performance, particularly in low-light conditions, and demand the fastest possible charging speeds – both wired and wireless – to minimize downtime.

Frequently Asked Questions

❓ Does the Exynos 990 in the Note20 Ultra overheat during prolonged gaming sessions?
The Exynos 990 is known to exhibit thermal throttling under sustained heavy loads, such as extended gaming. While not catastrophic, users may experience frame rate drops and reduced performance after prolonged use. The Mi 11 Ultra’s Snapdragon 888, with its 5nm process, generally manages heat more effectively.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up shots?
Generally, 2MP macro cameras on flagship phones are more of a marketing feature than a genuinely useful tool. The low resolution results in images lacking detail and sharpness. Both phones would benefit from a higher-resolution macro lens, but the Mi 11 Ultra’s superior main sensor can often achieve acceptable close-up shots through digital zoom.
❓ Can the Note20 Ultra handle 90fps gaming in titles like PUBG Mobile?
The Note20 Ultra can achieve 90fps in PUBG Mobile, but it may require lowering graphics settings to maintain a stable frame rate, especially with the Exynos variant. The Mi 11 Ultra’s more powerful Snapdragon 888 will consistently deliver a smoother 90fps experience at higher graphics settings.
❓ How does the S Pen integration affect the Note20 Ultra's overall usability for professionals?
The S Pen is a core feature of the Note20 Ultra, offering a natural writing and drawing experience. Professionals can use it for note-taking in meetings, annotating documents, signing PDFs, and precise photo editing. The Air Actions feature adds another layer of control, making it a valuable tool for productivity.
