Feature-by-Feature Breakdown

Display

  • Galaxy S20: Features a 6.2-inch Dynamic AMOLED 2X display with a 120Hz refresh rate. While still vibrant and smooth, it lacks the peak brightness and color accuracy of newer models.
  • S24: Boasts a 6.2-inch Dynamic AMOLED 2X display with an adaptive 120Hz refresh rate and significantly higher peak brightness. It offers superior outdoor visibility and more vivid colors.
  • Winner: s24

Processor

  • Galaxy S20: Powered by the Exynos 990 or Snapdragon 865, depending on the region. These processors were top-tier at launch but struggle with demanding modern applications and multitasking compared to current flagships.
  • S24: Equipped with the latest Snapdragon 8 Gen 3 for Galaxy or Exynos 2400. These chips offer substantial leaps in performance, power efficiency, and AI capabilities, handling any task with ease.
  • Winner: s24

Camera System

  • Galaxy S20: Comes with a triple rear camera setup: 12MP ultrawide, 12MP wide, and 64MP telephoto. It delivers good photos in daylight but can be outperformed in low light and zoom capabilities by newer devices.
  • S24: Features an upgraded triple rear camera system: 50MP wide, 12MP ultrawide, and 10MP telephoto with 3x optical zoom. Improved sensor sizes and AI processing result in better detail, low-light performance, and zoom quality.
  • Winner: s24

Battery Life

  • Galaxy S20: Has a 4000 mAh battery. With its older processor and less efficient display technology, battery life can be a concern for heavy users, often requiring a midday charge.
  • S24: Equipped with a 4000 mAh battery, but benefits from a more power-efficient processor and display. This translates to noticeably better all-day battery performance for most users.
  • Winner: s24

Software Updates

  • Galaxy S20: Has reached its end of major software updates, receiving only security patches. This means it will not get new Android versions or Samsung One UI feature enhancements.
