Samsung Galaxy S20

  • Brighter display for outdoor visibility
  • Snapdragon 865 variant offers strong performance (US model)
  • More widely available software ecosystem

  • Inferior battery life compared to P40 Pro+
  • Exynos 990 variant prone to throttling
  • Slower charging speeds

Huawei P40 Pro+

  • Exceptional battery life (95-hour endurance)
  • Faster 40W wired and wireless charging
  • Versatile camera system

  • Slightly dimmer display
  • Huawei ecosystem limitations
  • Potential software update concerns

Display Comparison

The Samsung Galaxy S20 boasts a peak brightness of 814 nits, exceeding the Huawei P40 Pro+'s 760 nits. While the S20 is brighter, both displays share an 'Infinite' contrast ratio, suggesting excellent black levels. The difference in brightness is noticeable in direct sunlight, giving the S20 a slight edge for outdoor visibility. However, neither manufacturer specifies PWM dimming rates, making it difficult to assess potential flicker-related eye strain for sensitive users.

Camera Comparison

Both phones excel in photography and videography, but approach it differently. While both are listed as having 'Photo / Video' capabilities, the P40 Pro+’s camera system is more comprehensively documented. The P40 Pro+’s strength lies in its versatile camera setup, though specific sensor details are missing in the provided data. The S20’s camera performance is solid, but lacks the P40 Pro+'s reputation for low-light photography and zoom capabilities. The absence of details on the S20’s camera sensors makes a direct comparison difficult, but the P40 Pro+ likely holds an advantage in overall image quality.

Performance

The performance landscape is complex. Globally, the Galaxy S20 shipped with the Exynos 990, while the US received the Snapdragon 865. The Snapdragon 865, built on a 7nm+ process, generally offers superior sustained performance and thermal management compared to the Exynos 990. The P40 Pro+ utilizes the Kirin 990 5G (also 7nm+), featuring a slightly different CPU core configuration (2x Cortex-A76 vs S20's Mongoose M5 and A76). While clock speeds are comparable, real-world performance differences depend heavily on software optimization and thermal throttling. The S20’s potential for throttling on the Exynos variant is a concern for prolonged gaming sessions.

Battery Life

The Huawei P40 Pro+ decisively wins in battery life, achieving an endurance rating of 95 hours compared to the Galaxy S20’s 71 hours. This 24-hour difference is substantial. Furthermore, the P40 Pro+ supports significantly faster charging: 40W wired and 40W wireless, versus the S20’s 25W wired and 15W wireless. The P40 Pro+ also offers 27W reverse wireless charging, a feature the S20 provides at only 4.5W. This means the P40 Pro+ can top up accessories much faster. While the S20’s battery is adequate, the P40 Pro+ offers a far more convenient and long-lasting experience.

Buying Guide

Buy the Samsung Galaxy S20 if you need a compact flagship with a vibrant display and prefer the wider ecosystem of Google services. The Snapdragon 865 variant (US model) is ideal for demanding mobile gamers. Buy the Huawei P40 Pro+ if you prioritize exceptional battery life, fast charging speeds, and a versatile camera system, and are comfortable with the Huawei ecosystem.

Frequently Asked Questions

❓ Does the Exynos 990 in the Galaxy S20 overheat during extended gaming sessions?
Yes, the Exynos 990 variant of the Galaxy S20 is known to experience thermal throttling under sustained load, such as prolonged gaming. This can lead to reduced performance and frame rate drops. The Snapdragon 865 version (available in the US) handles heat more effectively.
❓ How does the 40W wireless charging on the P40 Pro+ compare to the S20's 15W wireless charging in real-world use?
The P40 Pro+'s 40W wireless charging is significantly faster. A full wireless charge on the P40 Pro+ will take roughly half the time compared to the S20. This makes topping up the P40 Pro+ overnight or during short breaks much more convenient.
❓ Is the lack of Google Mobile Services (GMS) on the P40 Pro+ a major issue for most users?
The absence of GMS was a significant drawback for the P40 Pro+ at launch. While Huawei has made efforts to build its own ecosystem (HMS), many users still rely heavily on Google apps. The impact depends on your reliance on services like Google Maps, Gmail, and the Play Store. Workarounds exist, but they add complexity.
❓ What is the practical benefit of the P40 Pro+'s 27W reverse wireless charging?
The P40 Pro+'s 27W reverse wireless charging allows you to quickly charge accessories like earbuds, smartwatches, or even another phone. Compared to the S20’s 4.5W reverse wireless charging, it’s substantially faster and more useful for emergency top-ups.
