vivo NEX 3S 5G

  • Extremely fast 44W wired charging
  • Unique waterfall display design
  • Snapdragon 865 5G chipset (comparable to S20+ USA variant)

  • Potentially limited software support and updates
  • Waterfall display may introduce accidental touches

Samsung Galaxy S20+ 5G

  • Versatile and high-quality camera system
  • Polished and feature-rich software experience
  • Wireless and reverse wireless charging

  • Slower 25W wired charging
  • Exynos 990 variant may experience thermal throttling

Display Comparison

Both devices utilize 7nm+ fabrication, but display differences are significant. While specific display specs (resolution, refresh rate) are missing for the NEX 3S, its defining feature is the 'waterfall' display, maximizing screen real estate. The S20+ features a 6.7-inch Dynamic AMOLED 2X display. Samsung’s AMOLED technology is known for its vibrant colors and excellent contrast. The S20+ likely benefits from a higher peak brightness and potentially better color accuracy due to Samsung’s display calibration expertise. The NEX 3S’s waterfall design, while visually striking, may introduce accidental touch inputs.

Camera Comparison

The Galaxy S20+ 5G boasts a more comprehensive camera system. While specific sensor details for the NEX 3S are limited, the S20+ features a 12MP main sensor with OIS, a 64MP telephoto lens with 3x hybrid optical zoom, and a 12MP ultrawide lens. Samsung’s image processing is renowned for its vibrant colors and detail preservation. The S20+ also excels in video recording, offering 8K video capture. The NEX 3S likely relies heavily on software processing to compensate for potentially less advanced hardware. The S20+'s superior optical zoom capabilities and video recording features provide a significant advantage for photography enthusiasts.

Performance

The performance landscape is complex due to the S20+'s chipset variation. The USA variant receives the Qualcomm Snapdragon 865 5G (7nm+), identical to the NEX 3S. This means both will offer comparable CPU performance, with the Snapdragon 865’s octa-core configuration (1x2.84 GHz Cortex-A77, 3x2.42 GHz Cortex-A77, 4x1.80 GHz Cortex-A55) mirroring the NEX 3S. However, the global S20+ uses the Exynos 990 (7nm+), featuring a different CPU architecture (2x2.73 GHz Mongoose M5, 2x2.50 GHz Cortex-A76, 4x2.0 GHz Cortex-A55). The Exynos 990 has historically faced criticism for thermal throttling under sustained load, potentially impacting gaming performance compared to the Snapdragon variant. Both devices utilize LPDDR5 RAM, ensuring fast memory access.

Battery Life

The vivo NEX 3S 5G distinguishes itself with 44W wired charging, significantly faster than the S20+'s 25W wired charging (with PD3.0 support). This translates to a substantially quicker 0-100% charge time for the NEX 3S. The S20+ compensates with 15W wireless charging (Qi standard) and 4.5W reverse wireless charging, features absent on the NEX 3S. While battery capacity isn’t specified for the NEX 3S, the S20+ packs a 4500mAh battery. The faster charging of the NEX 3S is beneficial for users who frequently need to top up their battery quickly, but the S20+'s wireless charging and larger capacity offer greater convenience and longevity.

Buying Guide

Buy the vivo NEX 3S 5G if you prioritize extremely fast 44W charging and a unique, nearly bezel-less waterfall display, and are comfortable with potential software quirks. Buy the Samsung Galaxy S20+ 5G if you value a polished software experience, a versatile camera system with strong video capabilities, and the benefits of Samsung’s broader ecosystem, particularly if you can secure the Snapdragon 865 variant.

Frequently Asked Questions

❓ Does the Exynos 990 in the global S20+ 5G overheat during prolonged gaming sessions?
Yes, the Exynos 990 has been known to exhibit thermal throttling under sustained load, particularly during graphically intensive gaming. This can lead to reduced performance and frame rate drops. The Snapdragon 865 variant does not suffer from this issue to the same extent.
❓ Is the waterfall display on the vivo NEX 3S 5G prone to accidental touches?
The curved edges of the waterfall display can indeed lead to accidental touches, especially when holding the phone. vivo likely implemented software optimizations to mitigate this, but it remains a potential usability concern.
❓ How does the image processing differ between the NEX 3S and the S20+?
Samsung's image processing tends to produce vibrant, saturated images with enhanced detail. The NEX 3S likely relies more on software algorithms to improve image quality, potentially resulting in a less natural look. The S20+ also offers more advanced features like Single Take and Pro Video mode.
❓ Does the Samsung Galaxy S20+ 5G support 90fps gaming?
While the S20+ 5G's display has a 120Hz refresh rate, achieving 90fps in games depends on the game's optimization. Some titles support higher frame rates, while others are capped at 60fps. The Snapdragon 865 variant is better equipped to handle higher frame rates consistently.
