Ratings

The Samsung Galaxy S23 Plus and the Samsung Galaxy S24 Ultra are flagship smartphones from consecutive generations, offering distinct experiences within the Android ecosystem. While both devices provide a premium Android experience, the S24 Ultra, released in January 2024, introduces a more advanced camera system, a newer processor, and extended software support compared to the S23 Plus, which launched in February 2023. Both run on Samsung's One UI atop the Android operating system, but the S24 Ultra benefits from a more recent Android version at launch and a longer commitment to future updates.

Scores

Durability

When considering the long-term usability of these devices, several factors contribute to their expected practical lifespan, including software support and physical resilience.

  • Software Longevity: The Galaxy S23 Plus, released in February 2023, was launched with Android 13 and is expected to receive four years of operating system updates and five years of security updates, extending its support until approximately 2028. In contrast, the Galaxy S24 Ultra, launched in January 2024 with Android 14, offers a significantly longer commitment of seven years of both OS and security updates, meaning support will continue until around 2031. This extended support period provides the S24 Ultra with a longer window for receiving new features and security patches.
  • Physical Durability: Both devices feature an IP68 rating for dust and water resistance, indicating protection against immersion in up to 1.5 meters of fresh water for 30 minutes. The S23 Plus utilizes Corning Gorilla Glass Victus 2 for its front and back, paired with an aluminum frame. The S24 Ultra elevates this with a titanium frame and Corning Gorilla Glass Armor on the display, which offers superior scratch resistance.
  • Repairability: The Galaxy S24 Ultra has demonstrated a high repairability score, with teardowns indicating a score of 9 out of 10. This suggests that components like the battery and charger port are relatively accessible for replacement, contributing to a potentially longer serviceable life.
