Samsung Galaxy S20 Ultra 5G

  • Brighter display for outdoor visibility
  • Samsung ecosystem integration
  • Potentially better camera software (depending on preference)

  • Exynos 990 can suffer from throttling
  • Slower charging speeds
  • Lower battery endurance

Xiaomi Mi 10 Pro 5G

  • Snapdragon 865 provides consistent performance
  • Faster 50W wired and 30W wireless charging
  • Longer battery life
  • More aggressive price point

Display Comparison

The Samsung Galaxy S20 Ultra’s display achieves a measured peak brightness of 894 nits, exceeding the Mi 10 Pro’s 858 nits. This difference is noticeable in direct sunlight, giving the S20 Ultra an edge for outdoor use. However, the Mi 10 Pro counters with an 'Infinite' contrast ratio, typical of AMOLED panels, providing deep blacks. Both utilize AMOLED technology, but Samsung’s panel is larger and slightly brighter, though the difference isn’t massive. Neither phone specifies refresh rate, implying standard 60Hz panels, a notable omission compared to later flagships.

Camera Comparison

Both phones feature capable camera systems, but approach image processing differently. While both offer photo and video capabilities, detailed sensor information is lacking in the provided data. The Mi 10 Pro’s image processing tends towards more saturated colors, while Samsung historically favors a more natural look, though often with aggressive sharpening. The absence of specific sensor details makes a direct comparison difficult, but the Snapdragon 865’s ISP is generally regarded as excellent for image processing. The usefulness of any 2MP macro lenses on either device is questionable, offering limited practical benefit over the main sensors.

Performance

The core difference lies in the chipset. The Mi 10 Pro exclusively uses the Qualcomm Snapdragon 865 5G (7nm+), while the S20 Ultra shipped with either the Exynos 990 (7nm+) in global markets or the Snapdragon 865 in the USA. The Snapdragon 865, with its Cortex-A77 cores, generally offers more consistent performance and better thermal management than the Exynos 990. The Exynos 990 has been known to throttle under sustained load, impacting gaming and demanding tasks. Both phones feature an octa-core CPU configuration, but the Snapdragon’s architecture provides a performance advantage. Both utilize LPDDR5 RAM, but the Exynos variant's thermal limitations can negate some of the RAM's benefits.

Battery Life

The Xiaomi Mi 10 Pro boasts a significant advantage in battery endurance, achieving a rating of 101 hours compared to the S20 Ultra’s 87 hours. This is further bolstered by the Mi 10 Pro’s superior charging capabilities: 50W wired charging, capable of a full charge in under 40 minutes, and 30W wireless charging. The S20 Ultra offers 45W wired charging and slower 15W wireless charging. While the S20 Ultra’s battery capacity isn’t specified, the endurance rating suggests it’s less efficient overall, likely due to the Exynos 990’s power consumption.

Buying Guide

Buy the Samsung Galaxy S20 Ultra 5G if you prioritize absolute peak display brightness for outdoor visibility and are heavily invested in the Samsung ecosystem. Buy the Xiaomi Mi 10 Pro 5G if you value faster charging, longer battery life, consistent performance from the Snapdragon 865, and a more aggressive price point.

Frequently Asked Questions

❓ Does the Exynos 990 in the S20 Ultra overheat during prolonged gaming sessions?
Yes, the Exynos 990 variant of the S20 Ultra is known to experience thermal throttling during extended gaming or demanding tasks. This can lead to reduced performance and frame rate drops, impacting the gaming experience. The Snapdragon 865 variant in the US model fares significantly better in this regard.
❓ How long does it take to fully charge the Xiaomi Mi 10 Pro with the 50W wired charger?
The Xiaomi Mi 10 Pro can be fully charged from 0% to 100% in approximately 35-40 minutes using the included 50W wired charger. This is significantly faster than the S20 Ultra’s 45W charging, offering a substantial convenience factor.
❓ Is the 2MP macro camera on either phone worth using?
Generally, the 2MP macro cameras on both the S20 Ultra and Mi 10 Pro offer limited practical benefit. The low resolution and fixed focus often result in images lacking detail and sharpness. The main sensors on both phones can achieve acceptable macro shots with proper technique.
❓ Does the Mi 10 Pro support high frame rate gaming like 90fps in PUBG?
The Mi 10 Pro, powered by the Snapdragon 865, is capable of running PUBG Mobile at high frame rates, potentially up to 60fps depending on the graphics settings. Achieving a consistent 90fps may be challenging, but the phone offers a smooth and responsive gaming experience.
