My Choice

If I were choosing, I'd opt for the Samsung Galaxy S21 5G. Here's why:

  • Prioritized Performance: The Exynos 2100 chipset gives it a significant edge in performance, making it suitable for demanding apps and games. I value that performance for general smoothness and longevity.
  • Superior Screen Brightness: I often use my phone outdoors, so the S21's 1300 nits brightness is a big plus. The brighter screen also helps when I view media outside.
  • Camera Versatility: I prefer having a telephoto lens for zoom, especially for portraits. Additionally, I value video quality and the high-resolution video is an important benefit.
  • Build Quality: The superior Corning Gorilla Glass Victus gives added confidence regarding the screen's durability.
  • Added Features: I like the convenience of wireless charging and reverse wireless charging. The extra sensors, though niche, indicate a greater level of technological integration.
  • DXOMark Scores: The fact that the camera has been tested gives an indication of the quality.

While the Realme 11 Pro+ has its strengths, especially the battery life and larger display, for me, the S21 edges out with a focus on performance and versatility. The Realme's advantages are less valuable to me, and the compromises it makes in brightness, performance, and camera versatility outweigh the benefits in other areas.
