Huawei Mate 40 Pro+

  • Blazing-fast 66W wired charging
  • Exceptional 50W wireless charging
  • Potentially superior low-light camera performance

  • Limited software support and ecosystem
  • Availability issues in some regions
  • Uncertain long-term software updates

Samsung Galaxy S21 Ultra 5G

  • Brighter and more versatile display
  • Wider software support and ecosystem
  • Strong video recording capabilities

  • Slower charging speeds (25W wired)
  • Exynos variant may exhibit thermal throttling
  • Less aggressive camera processing

Display Comparison

The Samsung Galaxy S21 Ultra boasts a brighter display, peaking at 1023 nits measured, compared to an unspecified peak brightness for the Mate 40 Pro+. While the Mate 40 Pro+ likely offers excellent color accuracy, the S21 Ultra’s higher brightness translates to better outdoor visibility. Both devices feature dynamic refresh rates, but Samsung’s implementation with LTPO technology allows for more granular control, potentially improving battery efficiency. The S21 Ultra’s ‘Infinite’ contrast ratio, while a marketing term, suggests deep blacks typical of AMOLED panels.

Camera Comparison

Both phones excel in photography, but approach it differently. While detailed sensor specs are missing for the Mate 40 Pro+, Huawei is known for its computational photography prowess and large sensor sizes. The S21 Ultra’s camera system is incredibly versatile, offering multiple lenses and advanced features. The S21 Ultra’s video capabilities are particularly strong, benefiting from Samsung’s image processing algorithms. The Mate 40 Pro+ likely excels in low-light photography due to Huawei’s RYYB sensor technology, while the S21 Ultra provides more consistent results across various lighting conditions. Ignoring the 2MP macro sensors on both devices, the core camera systems are highly competitive.

Performance

The chipset battle is complex. The Huawei Mate 40 Pro+ utilizes the Kirin 9000 5G (5nm), featuring a Cortex-A77 based CPU. The Galaxy S21 Ultra comes in two variants: the Exynos 2100 (5nm) for international markets and the Qualcomm Snapdragon 888 5G (5nm) for USA/China. The Snapdragon 888 and Exynos 2100 both employ the newer Cortex-X1 prime core, offering a potential performance edge over the Kirin 9000’s A77. However, the Kirin 9000’s larger cache and optimized architecture could mitigate this difference. Real-world performance will vary based on software optimization and thermal management, but the Snapdragon 888 generally exhibits better sustained performance due to its more efficient 5nm process.

Battery Life

The Samsung Galaxy S21 Ultra achieves an endurance rating of 114 hours, indicating solid battery life. The Mate 40 Pro+’s battery capacity is unspecified, but its 66W wired charging is a significant advantage, allowing for a full charge in under an hour. The S21 Ultra’s 25W charging is comparatively slow. The Mate 40 Pro+ also offers 50W wireless charging, dwarfing the S21 Ultra’s 15W Qi wireless charging. While the S21 Ultra’s battery life is respectable, the Mate 40 Pro+’s charging speed offers a more convenient user experience.

Buying Guide

Buy the Huawei Mate 40 Pro+ if you prioritize exceptionally fast 66W wired and 50W wireless charging, and are a dedicated mobile photographer willing to navigate the limitations of Huawei’s ecosystem. Buy the Samsung Galaxy S21 Ultra 5G if you value a vibrant, high-brightness display, a more mainstream software experience, and a versatile camera system with strong video capabilities, alongside broader 5G band support.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the Galaxy S21 Ultra overheat during prolonged gaming sessions?
The Exynos 2100 variant of the S21 Ultra has been reported to exhibit more thermal throttling than the Snapdragon 888 version during extended gaming. While not a deal-breaker, users may experience slight performance drops after prolonged use. Optimizing game settings and ensuring adequate ventilation can help mitigate this issue.
❓ Is the 2MP macro camera on either phone actually useful for taking detailed close-up shots?
Generally, the 2MP macro cameras on both the Mate 40 Pro+ and S21 Ultra are of limited utility. Their low resolution results in images lacking detail and sharpness. They are primarily included for marketing purposes and are unlikely to significantly enhance your mobile photography experience.
❓ Can the Samsung Galaxy S21 Ultra consistently maintain 60fps or higher in demanding games like PUBG Mobile?
The Galaxy S21 Ultra, particularly the Snapdragon 888 variant, can consistently achieve 60fps or higher in PUBG Mobile at high graphics settings. However, maintaining a stable framerate at the absolute highest settings may require some optimization and could be affected by background processes.
❓ What are the implications of Huawei's lack of Google Mobile Services (GMS) on the Mate 40 Pro+?
The absence of GMS means the Mate 40 Pro+ does not natively support Google apps like Gmail, YouTube, and Google Maps. Users must rely on Huawei’s AppGallery and alternative methods for installing these apps, which can be less convenient and may raise security concerns.
