Galaxy S21 FE 5G vs iPhone Air

Samsung Galaxy S21 FE 5G, released in January 2022, and the iPhone Air, introduced in September 2025, represent distinct approaches to smartphone design and functionality. While the Galaxy S21 FE 5G operates on the Android platform, offering a customizable experience, the iPhone Air runs on Apple's iOS, known for its integrated ecosystem. The primary differentiators lie in their release timelines, design philosophies, and camera systems, catering to different user preferences.

The longevity of a smartphone is influenced by its build quality, software support, and the availability of replacement parts. These two devices offer different propositions in terms of their expected practical lifespan.

• Release Timeline: The Galaxy S21 FE 5G was released in early 2022, while the iPhone Air debuted in late 2025. This nearly four-year difference means the iPhone Air benefits from a more recent hardware foundation and will likely receive software updates for a longer period, extending its functional life.
• Software Support: Samsung typically provides several years of Android OS updates and security patches for its flagship and FE series devices. The iPhone Air, being a newer Apple device, is expected to receive iOS updates for an extended duration, potentially offering a longer period of access to the latest features and security enhancements.
• Physical Durability: The Galaxy S21 FE 5G features Corning Gorilla Glass Victus on its display and an IP68 rating for dust and water resistance, indicating a robust build for everyday use. The iPhone Air, on the other hand, incorporates a polished titanium frame and Ceramic Shield 2 for enhanced front and back protection, designed to be highly resistant to scratches and cracks, and also carries an IP rating for water and dust resistance.

Performance in a smartphone is about how smoothly it handles daily tasks, demanding applications, and multitasking. Both devices are equipped to deliver capable experiences, though with different underlying architectures.

• Processing Power: The Galaxy S21 FE 5G is powered by a processor that handles demanding apps and multitasking efficiently, providing a responsive user experience for gaming and productivity. The iPhone Air features Apple's A19 Pro system-on-chip, which delivers advanced processing and graphics rendering capabilities, ensuring smooth operation even with the most intensive applications and complex tasks.
• Multitasking and Responsiveness: The Galaxy S21 FE 5G offers various RAM configurations, contributing to its ability to manage multiple applications simultaneously without significant slowdowns. The iPhone Air's optimized hardware and software integration, driven by its A19 Pro chip, allows for fluid transitions between apps and consistently quick response times, even under heavy load.
• Storage Options: The Galaxy S21 FE 5G comes with internal storage options up to 256GB, providing ample space for apps, photos, and videos. The iPhone Air offers larger storage capacities, including 256GB, 512GB, and 1TB, catering to users with extensive digital content needs.

The display is a primary interface for smartphone interaction, and both models offer high-quality visual experiences with distinct characteristics.

• Display Technology and Clarity: The Galaxy S21 FE 5G features a 6.4-inch Dynamic AMOLED 2X display, known for its vibrant colors, deep blacks, and excellent contrast. The iPhone Air sports a 6.5-inch Super Retina XDR OLED display, which also delivers rich colors and deep blacks, offering a highly immersive viewing experience.
• Brightness and Outdoor Visibility: The Galaxy S21 FE 5G's display can reach a peak brightness of 1300 nits, ensuring good visibility in various lighting conditions, including direct sunlight. The iPhone Air significantly surpasses this with a peak brightness of 3000 nits, making its screen exceptionally clear and readable even in very bright outdoor environments.
• Refresh Rate and Smoothness: The Galaxy S21 FE 5G offers a 120Hz refresh rate, providing smooth scrolling and a more fluid visual experience, though it is not adaptive. The iPhone Air features an adaptive ProMotion display with a refresh rate that dynamically adjusts from 1Hz to 120Hz, optimizing smoothness while conserving battery life.

Camera capabilities are a significant factor for many users, and both devices provide advanced photographic and videographic tools, albeit with different configurations.

• Rear Camera System: The Galaxy S21 FE 5G is equipped with a versatile triple-camera system, including a 12MP wide-angle lens, a 12MP ultra-wide lens, and an 8MP telephoto lens with 3x optical zoom, allowing for a range of photographic perspectives. The iPhone Air features a single 48MP Fusion camera system on the rear, which is designed to capture high-quality wide-angle shots and offers 2x optical-quality zoom through advanced processing.
• Low-Light and Video Performance: The Galaxy S21 FE 5G performs well in various lighting conditions, with its main sensor capable of capturing detailed images, and it supports 4K video recording at 30/60fps. The iPhone Air's camera system, combined with its powerful processor, is optimized for excellent image quality across different scenarios, and it supports advanced video features like Dual Capture.
• Front Camera: For selfies and video calls, the Galaxy S21 FE 5G includes a 32MP front camera. The iPhone Air features an 18MP Center Stage front camera, which intelligently adjusts to keep subjects in frame during video calls.
