vivo S21 Pro

  • Significantly faster 90W charging
  • More powerful and efficient Dimensity 9300+ chipset
  • Potentially better thermal management

  • Brand recognition is lower than Samsung
  • Display specifications are less detailed

Samsung Galaxy S21+ 5G

  • Established brand reputation
  • High-quality AMOLED display with good brightness
  • Refined software experience

  • Slower 25W charging
  • Older Exynos 2100/Snapdragon 888 chipset
  • Potential for throttling under heavy load

Display Comparison

The Samsung Galaxy S21+ 5G boasts a peak brightness of 883 nits, a respectable figure, but the vivo S21 Pro’s display specifications are not provided. Given vivo’s recent offerings, it’s likely comparable. However, the S21+’s ‘Infinite’ contrast ratio suggests a high-quality AMOLED panel. The absence of LTPO technology in the S21+ means the refresh rate is likely fixed, while the S21 Pro’s display tech is unknown. The S21+'s display is well-regarded for its color accuracy, but without detailed specs for the S21 Pro, a definitive judgment is difficult.

Camera Comparison

Both phones offer capable camera systems, but detailed sensor information is limited. The S21+’s camera is known for its versatile photo and video capabilities. However, without knowing the sensor sizes and apertures of the vivo S21 Pro, a direct comparison is challenging. The S21+'s image processing leans towards vibrant colors, while vivo typically aims for a more natural look. The presence of OIS on both devices is expected, but the effectiveness will depend on the specific implementation. The inclusion of a 2MP macro camera on the S21+ is largely a marketing gimmick and offers limited practical benefit.

Performance

The vivo S21 Pro’s Mediatek Dimensity 9300+ (4nm) represents a significant leap over the Samsung Galaxy S21+ 5G’s Exynos 2100 (5nm) or Snapdragon 888 (5nm). The Dimensity 9300+ features a unique core configuration – 1x3.25 GHz Cortex-X4, 3x2.85 GHz Cortex-X4, and 4x2.0 GHz Cortex-A720 – offering a blend of peak performance and efficiency. The S21+'s CPU, with its Cortex-X1 and A78 cores, is older architecture. The 4nm process of the Dimensity 9300+ provides better thermal efficiency than the 5nm Exynos/Snapdragon, potentially leading to less throttling during sustained workloads. This translates to smoother gaming and faster app loading times for the vivo S21 Pro.

Battery Life

The Samsung Galaxy S21+ 5G has an endurance rating of 114 hours, indicating decent battery life. However, the vivo S21 Pro’s 90W wired charging is a game-changer. While the S21+ tops out at 25W, the S21 Pro can fully charge its battery in a fraction of the time. The S21+ also supports 15W wireless and 4.5W reverse wireless charging, while the S21 Pro offers reverse *wired* charging, a potentially faster option. The faster charging speed of the S21 Pro effectively mitigates any potential battery capacity differences.

Buying Guide

Buy the vivo S21 Pro if you prioritize charging speed, future-proof performance, and a modern chipset architecture. It’s ideal for power users and gamers who demand responsiveness. Buy the Samsung Galaxy S21+ 5G if you prefer a more established brand with a proven track record, and value a slightly more refined software experience, accepting compromises in charging and processing power.

Frequently Asked Questions

❓ Does the Exynos 2100 in the Galaxy S21+ 5G suffer from overheating during prolonged gaming sessions?
The Exynos 2100, particularly in the S21+ 5G, was known to exhibit thermal throttling under sustained load, especially during demanding games. While not catastrophic, users reported reduced performance after extended gaming. The Dimensity 9300+ in the vivo S21 Pro, built on a more efficient 4nm process, is less prone to overheating.
❓ How long does it take to fully charge the vivo S21 Pro with its 90W charging?
The vivo S21 Pro’s 90W charging can typically fully charge a battery from 0% to 100% in around 30-40 minutes, a substantial improvement over the S21+'s 25W charging which takes over an hour.
❓ Is the reverse wired charging on the vivo S21 Pro significantly faster than the reverse wireless charging on the Samsung Galaxy S21+ 5G?
Yes, reverse *wired* charging is considerably faster than reverse *wireless* charging. Wired charging delivers power directly, while wireless charging involves energy loss during transmission. The S21 Pro’s reverse wired charging will top up accessories much quicker than the S21+'s wireless option.
