Ratings

The Samsung Galaxy S21 5G, released in early 2021, and the Apple iPhone XS, launched in late 2018, represent two different eras of smartphone technology. While the Galaxy S21 offers modern features like 5G connectivity and a high-refresh-rate display, the iPhone XS remains a functional choice for those who prefer a more compact form factor and the iOS ecosystem. These devices cater to different user needs, with the Samsung focusing on contemporary hardware and the Apple model providing a classic, streamlined experience. Both smartphones continue to be relevant for users seeking reliable performance without needing the absolute latest release.

Scores

Durability

When evaluating how long these devices will remain functional and supported, the three-year age gap between them plays a significant role in their expected software longevity.

  • Software Support: The Galaxy S21 5G was released much later and continues to receive regular Android updates and security patches, ensuring it remains compatible with the latest apps for several more years. In contrast, the iPhone XS is approaching the end of its official iOS update cycle, which may eventually limit its ability to run newer software versions or receive the latest security features.
  • Physical Build and Repair: The iPhone XS features a stainless steel frame and glass back, offering a sturdy feel, while the Galaxy S21 uses a reinforced polycarbonate back that is less prone to shattering if dropped. Both devices have established repair networks, though finding replacement components for the newer Samsung model is often more straightforward in the current market due to its more recent production cycle.
  • Practical Lifespan: Users can expect the Galaxy S21 to have a longer operational horizon because its internal components were designed to handle the increasing demands of modern software for a longer period than the older hardware in the iPhone XS.

Performance

The performance gap between these two smartphones is most noticeable when handling demanding applications or multitasking between several resource-heavy programs.

  • System Responsiveness: The Galaxy S21 5G provides a very fluid experience when opening apps and navigating the interface, thanks to its more modern internal architecture and higher amount of temporary memory. The iPhone XS still handles daily tasks like messaging and web browsing reliably, but users may notice slight delays when launching large files or switching between many active apps simultaneously.
  • Battery Endurance: With a significantly larger battery capacity, the Galaxy S21 is better equipped to last through a full day of intensive use, including video streaming and navigation. The iPhone XS has a smaller battery that may require a mid-day charge for users who frequently use their device throughout the day for power-hungry tasks.
  • Storage and Multitasking: Both devices offer various storage capacities to house photos and files, but the Galaxy S21's higher memory allowance allows it to keep more apps open in the background without needing to refresh them, which aids productivity for professional users.

Screen quality

The display technology used in these devices highlights the evolution of mobile screens, particularly regarding smoothness and outdoor visibility.

  • Display Fluidity: The Galaxy S21 features a high-refresh-rate screen that makes scrolling through social media feeds and animations appear much smoother than the standard refresh rate found on the iPhone XS. This difference is immediately apparent to users who prioritise a responsive visual experience during gaming or browsing.
  • Size and Clarity: The iPhone XS offers a 5.8-inch display that is easier to use with one hand, while the Galaxy S21 provides a larger 6.2-inch viewing area. Both use OLED technology, which ensures deep blacks and high contrast, but the Samsung model achieves higher peak brightness, making it easier to read under direct sunlight.
  • Viewing Experience: While the iPhone XS has a noticeable notch at the top for its sensors, the Galaxy S21 uses a small circular cutout for the front camera, providing more usable screen real estate for watching videos or playing games without visual interruptions.

Audiovisual

Photography and video capabilities differ significantly due to the hardware advancements made in the years separating these two releases.

  • Camera Versatility: The Galaxy S21 5G features a triple-lens system, including a dedicated high-resolution telephoto lens for zooming and an ultra-wide lens for landscapes. The iPhone XS utilizes a dual-lens setup that performs well for standard portraits but lacks the wide-angle perspective and advanced zoom range of its competitor.
  • Low-Light Performance: In darker environments, the Galaxy S21 uses more advanced image processing to capture clearer photos with less digital noise. The iPhone XS produces natural-looking images in good lighting, but its performance in dim settings shows the limitations of older sensor technology compared to more recent standards.
  • Video and Audio: Both devices record high-quality video, but the Galaxy S21 supports higher resolutions and offers more stable footage during movement. For audio, both feature stereo speakers, though the Samsung model provides a slightly more expansive soundstage for media consumption and clearer microphone pickup for calls.

Miscellaneous

Practical features such as connectivity and physical dimensions often dictate how a device fits into a user's daily routine and existing tech ecosystem.

  • Connectivity Standards: A major differentiator is the Galaxy S21's support for 5G networks, allowing for faster data speeds in areas with coverage. The iPhone XS is limited to 4G LTE, which is still sufficient for most tasks but lacks the future-proofing of the newer standard for users who travel or work in high-speed zones.
  • Biometrics and Ports: The iPhone XS relies on facial recognition for security, which is highly secure but can be slower when wearing certain accessories. The Galaxy S21 uses an ultrasonic fingerprint sensor embedded under the screen for quick access. Additionally, the Samsung uses a universal USB-C port, while the Apple device uses the proprietary Lightning connector.
  • Portability and Build: The iPhone XS is slightly heavier due to its stainless steel construction but has a smaller footprint, making it a preferred choice for those who value pocketability. The Galaxy S21 is lighter and taller, offering a balance between screen size and handling comfort for users who spend a lot of time on their phones.

In summary, the choice between the Samsung Galaxy S21 5G and the iPhone XS depends largely on whether a user prioritizes modern technical capabilities or a compact, familiar interface. User feedback on community forums often praises the Galaxy S21 for its exceptionally smooth screen and versatile camera system, though some users note that the plastic back feels different compared to traditional glass. On the other hand, the iPhone XS is frequently lauded for its durable build quality and the longevity of the iOS experience, even if its battery life and camera features are now surpassed by newer models.

Users who prioritize long-term software support, 5G connectivity, and a larger, smoother display will find the Galaxy S21 5G to be a well-suited choice for their needs. Conversely, users who prefer a smaller device that fits easily in the hand and who are already comfortable within the Apple ecosystem may lean toward the iPhone XS. Choosing a quality-assured refurbished option for either of these models is a sustainable choice that helps reduce electronic waste while providing a reliable smartphone experience. Ultimately, both devices remain capable tools, with the Galaxy S21 offering a more contemporary feature set and the iPhone XS serving as a dependable, eco-friendly alternative for those with more modest requirements.
