Huawei Mate 40 RS Porsche Design

  • Blazing-fast 66W wired charging
  • Unique Porsche Design aesthetic
  • Powerful Kirin 9000 5G chipset

  • Limited software support due to US sanctions
  • Availability is restricted
  • Display likely inferior to S21 Ultra in brightness

Samsung Galaxy S21 Ultra 5G

  • Excellent camera system with versatile features
  • Bright and vibrant display
  • Widespread availability and software support

  • Slower charging speeds (25W wired)
  • Exynos 2100 can exhibit thermal throttling
  • Higher price point for some configurations

Display Comparison

The Samsung Galaxy S21 Ultra’s display dominates with a measured peak brightness of 1023 nits, ensuring excellent visibility even in direct sunlight. While the Mate 40 RS’s display specifications aren’t detailed, it’s unlikely to match the S21 Ultra’s peak output. The S21 Ultra’s 'Infinite' contrast ratio, typical of AMOLED panels, delivers deep blacks and vibrant colors. The S21 Ultra’s adaptive refresh rate (not specified in the data, but standard for the model) further enhances smoothness, a feature likely absent in the Mate 40 RS.

Camera Comparison

Both phones are equipped with advanced camera systems, but the S21 Ultra’s versatility is noteworthy. While both are described as having 'Photo / Video' capabilities, the S21 Ultra’s sensor details (not provided) are likely to include a larger main sensor and more sophisticated image processing algorithms. The Mate 40 RS’s camera system is likely optimized for Huawei’s distinct color science, while the S21 Ultra aims for a more natural look. The absence of detail regarding the Mate 40 RS’s sensor sizes makes a direct comparison difficult, but the S21 Ultra’s reputation for consistent image quality gives it an advantage.

Performance

Both devices utilize 5nm fabrication processes, but the chipsets differ significantly. The Samsung Galaxy S21 Ultra offers a choice between the Exynos 2100 (international) and the Qualcomm Snapdragon 888 5G (USA/China). The Snapdragon 888 generally exhibits superior thermal management and sustained performance. The Huawei Mate 40 RS, powered by the Kirin 9000 5G, features a Cortex-A77 based CPU architecture, while the S21 Ultra utilizes the newer Cortex-X1 and A78 cores. This architectural advantage gives the S21 Ultra a theoretical edge in single-core performance, as evidenced by the 2.9 GHz Cortex-X1 prime core versus the Mate 40 RS’s 3.13 GHz Cortex-A77. However, real-world performance will depend on software optimization and thermal throttling.

Battery Life

The Samsung Galaxy S21 Ultra boasts an endurance rating of 114 hours, indicating solid battery life. While the Mate 40 RS’s battery capacity isn’t specified, its 66W wired charging significantly outpaces the S21 Ultra’s 25W charging. This translates to a much faster 0-100% charge time for the Mate 40 RS. The 50W wireless charging on the Mate 40 RS is also considerably faster than the S21 Ultra’s 15W Qi wireless charging. However, faster charging doesn’t necessarily equate to longer battery life; the S21 Ultra’s endurance rating suggests efficient power management.

Buying Guide

Buy the Huawei Mate 40 RS Porsche Design if you prioritize a unique, head-turning design, exceptionally fast 66W wired and 50W wireless charging, and are comfortable navigating the limitations of Huawei’s software ecosystem. Buy the Samsung Galaxy S21 Ultra 5G if you value a consistently excellent camera experience, a vibrant and bright display, widespread availability, and a fully-featured Android experience with guaranteed software updates.

Frequently Asked Questions

❓ Does the Exynos 2100 in the S21 Ultra overheat during prolonged gaming sessions?
The Exynos 2100 has been known to exhibit some thermal throttling under sustained load, particularly in warmer environments. However, Samsung implemented software optimizations to mitigate this issue, and the Snapdragon 888 variant generally performs better in this regard. The S21 Ultra’s vapor chamber cooling system also helps to manage temperatures.
❓ Is the 2MP macro camera on either phone actually useful for 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. While they can capture close-up shots, the quality is often inferior to using the main camera in a standard photo mode and digitally zooming.
❓ Does the Samsung Galaxy S21 Ultra support 90fps gameplay in demanding titles like PUBG?
The Samsung Galaxy S21 Ultra can achieve frame rates close to 90fps in PUBG Mobile, but it depends on the graphics settings and the specific device variant (Exynos or Snapdragon). Lowering the graphics settings to balanced or smooth will consistently deliver high frame rates. The Snapdragon variant generally maintains higher frame rates for longer periods due to better thermal performance.
❓ How does Huawei's software situation affect the Mate 40 RS Porsche Design's long-term usability?
Due to US sanctions, the Mate 40 RS lacks full Google Mobile Services (GMS) support. This means no pre-installed Google apps like Gmail, YouTube, or the Play Store. While Huawei's AppGallery offers alternatives, the app selection is limited, and some apps may not function correctly. This significantly impacts the long-term usability and convenience for users accustomed to the Google ecosystem.
