Display Comparison

The Samsung Galaxy S21 Ultra 5G features a significantly brighter display, peaking at 1023 nits measured, compared to the Mate 40 Pro 4G (brightness data unavailable). This translates to better outdoor visibility. While the Mate 40 Pro’s display quality is likely excellent given Huawei’s history, the S21 Ultra’s ‘Infinite’ contrast ratio and higher peak brightness provide a more immersive viewing experience. The S21 Ultra’s panel likely utilizes LTPO technology for variable refresh rates, potentially improving battery efficiency, a feature not confirmed for the Mate 40 Pro.

Camera Comparison

Both phones excel in photography, but approach it differently. While detailed sensor information is missing for the Mate 40 Pro, Huawei’s computational photography is renowned. The S21 Ultra’s camera system, with its multiple lenses, offers versatility. The larger main sensor on the S21 Ultra (spec not provided in context) likely captures more light, improving low-light performance. Both devices offer video recording capabilities, but the S21 Ultra’s 8K video recording provides a higher resolution option. The Mate 40 Pro’s image processing tends towards more vibrant colors, while Samsung typically aims for a more natural look.

Performance

Both devices utilize 5nm fabrication processes, but the chipsets differ significantly. The Huawei Mate 40 Pro 4G’s Kirin 9000 employs a Cortex-A77 based CPU architecture, while the S21 Ultra’s Exynos 2100 (International) or Snapdragon 888 (USA/China) utilizes the newer Cortex-X1 and A78 cores. The Cortex-X1 in the S21 Ultra offers a performance advantage in single-core tasks. The S21 Ultra’s RAM configuration, offering up to 12GB, is comparable to the Mate 40 Pro. However, the Exynos 2100 has faced criticism regarding thermal throttling, potentially impacting sustained performance, a concern less prevalent with the Snapdragon 888 variant and the Kirin 9000.

Battery Life

The Samsung Galaxy S21 Ultra 5G boasts an endurance rating of 114 hours, indicating excellent battery life. While the Mate 40 Pro 4G’s battery capacity is unknown, the S21 Ultra’s 25W wired charging is significantly slower than the Mate 40 Pro’s 66W wired charging. The Mate 40 Pro also offers 50W wireless charging, dwarfing the S21 Ultra’s 15W wireless charging. This means the Mate 40 Pro can achieve a full charge much faster, a significant advantage for users who frequently need to top up their battery. The 4.5W reverse wireless charging on the S21 Ultra is also slower than the Mate 40 Pro’s 5W reverse wireless charging.

Buying Guide

Buy the Huawei Mate 40 Pro 4G if you prioritize camera versatility, exceptionally fast 66W wired and 50W wireless charging, and are comfortable with a 4G-only experience. Buy the Samsung Galaxy S21 Ultra 5G if you need 5G connectivity, a brighter and more color-accurate display, and a broader ecosystem of software support and accessories.

Frequently Asked Questions

❓ Does the Exynos 2100 chip in the Galaxy S21 Ultra 5G overheat during prolonged gaming sessions?
The Exynos 2100 variant of the Galaxy S21 Ultra 5G has been reported to experience thermal throttling under sustained load, such as during extended gaming. This can lead to reduced performance. The Snapdragon 888 variant generally performs better in this regard, offering more consistent performance over longer periods. However, even the Snapdragon version can get warm during intensive tasks.
❓ Is the 4G limitation of the Huawei Mate 40 Pro 4G a significant drawback in 2024?
Yes, the lack of 5G support is a significant drawback in 2024, especially as 5G networks become more widespread. While 4G remains functional, users will experience slower data speeds and may miss out on the benefits of 5G-enabled applications and services. This limitation significantly impacts the phone's future-proofing.
❓ How does the image processing differ between the Huawei Mate 40 Pro 4G and the Samsung Galaxy S21 Ultra 5G?
Huawei’s image processing typically emphasizes vibrant colors and strong contrast, often resulting in visually appealing but less natural-looking photos. Samsung, on the other hand, generally aims for a more realistic and balanced color profile. This difference in processing style caters to different user preferences.
