Ratings

The Samsung Galaxy S9, released in March 2018, and the Apple iPhone 7 Plus, launched in September 2016, represent two distinct approaches to smartphone design and functionality from their respective eras. While both devices offered premium experiences at their release, they differ significantly in their operating systems, display technologies, and camera philosophies. The Galaxy S9 runs on Android, offering a customizable interface, while the iPhone 7 Plus operates on Apple's iOS, known for its integrated ecosystem. These differences cater to varying user preferences and usage patterns.

Scores

Durability

When considering the long-term usability of these devices, their release timelines and software support are key factors. The iPhone 7 Plus, being older, has naturally reached the end of its major iOS update cycle, with its last official update being iOS 15. The Galaxy S9, released later, received its last major Android update to Android 10 in late 2020, with security updates concluding around March 2022.

  • Software Longevity: The iPhone 7 Plus received support from iOS 10 up to iOS 15, which was released in 2021, and continued to receive security updates for some time after. The Galaxy S9 launched with Android 8.0 and was officially updated to Android 10, with security updates ending in early 2022.
  • Physical Durability: Both devices offer water and dust resistance, with the Galaxy S9 rated IP68 and the iPhone 7 Plus rated IP67. This means they can withstand immersion in water to a certain depth for a limited time. The Galaxy S9 features a glass front and back with an aluminum frame, while the iPhone 7 Plus has an aluminum unibody design.
  • Practical Lifespan: Given that both phones are past their major software update cycles, their practical lifespan for daily use depends more on hardware resilience and user tolerance for older software. Users of both devices might find app compatibility becoming an issue over time, though security updates for older iOS versions have been provided even into early 2026 for some older iPhones.

Users often praise the Samsung Galaxy S9 for its vibrant AMOLED display, versatile camera with variable aperture, and the inclusion of a headphone jack and expandable storage. Common criticisms sometimes pointed to its battery life, which some heavy users found to be just average, and the software experience could be overwhelming for some. Conversely, the iPhone 7 Plus was frequently lauded for its robust performance, reliable iOS ecosystem, and the introduction of its dual-camera system with optical zoom and Portrait Mode. Some users, however, expressed disappointment with the removal of the headphone jack and a design that was largely similar to its predecessors.

Users prioritizing a highly customizable Android experience, a vivid display, and the flexibility of expandable storage and a traditional headphone jack may find the Galaxy S9 well-suited to their needs. Those who value a streamlined user experience, consistent performance within the Apple ecosystem, and a camera system focused on optical zoom and portrait photography might lean toward the iPhone 7 Plus. Both devices, while older, still offer functional smartphone experiences. For those looking for a sustainable choice, considering a quality-assured refurbished option for either model can provide an eco-friendly alternative to purchasing new.
