Galaxy S21 FE 5G • Locked AT&T vs iPhone 15 • Locked AT&T

The Samsung Galaxy S21 FE 5G, released in January 2022, and the Apple iPhone 15, launched in September 2023, represent distinct approaches to the modern smartphone experience. While both devices offer robust performance and advanced camera systems, they cater to different user preferences through their respective operating systems and hardware philosophies. The primary distinctions lie in their software ecosystems, display refresh rates, and biometric security methods.

When considering the long-term usability of a smartphone, factors such as software support and physical durability are key. These two devices offer different timelines for updates and varying approaches to construction.

• Software Longevity: The iPhone 15, running on iOS, typically receives major operating system updates for a longer duration, often extending to five or six years from its release. The Galaxy S21 FE 5G, an Android device, generally receives around four to five years of major Android updates and security patches from its January 2022 launch.
• Physical Durability: Both devices feature an IP68 rating for dust and water resistance, indicating protection against immersion in water. The iPhone 15 incorporates a Ceramic Shield front cover, designed for enhanced drop performance, alongside a color-infused glass back and an aluminum frame. The Galaxy S21 FE 5G utilizes Corning Gorilla Glass Victus for its display and features a plastic back with an aluminum frame.
• Repairability: While specific repairability scores can vary, both manufacturers offer repair services. The availability of parts and ease of repair can influence the practical lifespan of the device, allowing users to extend their phone's use through quality-assured refurbished options.

The performance of a smartphone is crucial for daily tasks, from navigating applications to engaging in demanding multimedia. Both the Galaxy S21 FE 5G and the iPhone 15 deliver capable experiences, though with differences in their underlying architecture and real-world impact.

• Processing Power: The iPhone 15 features a current-generation processor that handles demanding applications and multitasking smoothly, providing a responsive user experience. The Galaxy S21 FE 5G is equipped with a powerful processor that allows for efficient multitasking and graphics rendering, suitable for livestreaming and video editing.
• Battery Behavior: The Galaxy S21 FE 5G houses a 4500mAh battery, which, for many users, can last through a full day of typical use, though heavy usage, especially with the higher refresh rate display, may require more frequent charging. The iPhone 15, with its 3349mAh battery, is optimized for power efficiency, and users often report it comfortably lasting a full day on a single charge, showing improvements over previous models.
• Multitasking and Storage: Both devices offer various internal storage configurations, typically ranging from 128GB to 512GB, providing ample space for apps, photos, and media. The iPhone 15 comes with 6GB of RAM, while the Galaxy S21 FE 5G offers options for 6GB or 8GB of RAM, influencing how many applications can remain active in the background without needing to reload.

The display is a primary interface for smartphone interaction, and both devices offer vibrant and clear viewing experiences, albeit with distinct characteristics that cater to different visual preferences.

• Display Technology and Clarity: The iPhone 15 features a 6.1-inch Super Retina XDR OLED display, offering deep blacks, vibrant colors, and a high resolution of 2556x1179 pixels, resulting in sharp images and text. The Galaxy S21 FE 5G comes with a slightly larger 6.4-inch Dynamic AMOLED 2X display, also providing excellent color accuracy and contrast with a 1080 x 2400 pixel resolution.
• Refresh Rate and Smoothness: A notable difference is the refresh rate. The Galaxy S21 FE 5G boasts a 120Hz adaptive refresh rate, which contributes to smoother scrolling and more fluid animations, particularly noticeable during gaming or fast-paced content. The iPhone 15 maintains a standard 60Hz refresh rate, which is sufficient for most everyday tasks but does not offer the same level of visual fluidity as a higher refresh rate display.
• Brightness and Viewing Experience: The iPhone 15 offers high brightness levels, with a typical maximum of 1000 nits and a peak outdoor brightness of up to 2000 nits, ensuring good visibility even in bright sunlight. The Galaxy S21 FE 5G also provides ample brightness for outdoor use, though specific peak brightness figures are generally lower than the iPhone 15. The iPhone 15 also integrates the Dynamic Island, an interactive area around the front camera that displays alerts and live activities.

Both smartphones offer advanced camera systems designed to capture high-quality photos and videos, but they differ in their sensor configurations and image processing philosophies.

• Rear Camera Systems: The iPhone 15 features a dual-camera setup with a 48MP main sensor and a 12MP ultrawide lens. The 48MP main camera often produces 24MP images by default, leveraging pixel binning for enhanced detail and light capture, and can achieve a 2x optical-quality zoom by cropping the main sensor. The Galaxy S21 FE 5G comes with a versatile triple-camera system, including a 12MP main lens, a 12MP ultrawide lens, and an 8MP telephoto lens capable of 3x optical zoom.
• Photography Performance: The iPhone 15 excels in overall image quality, particularly in challenging lighting conditions, due to its larger sensor and advanced computational photography. The Galaxy S21 FE 5G delivers good results in well-lit environments, with consistent color balance across its lenses. Its dedicated telephoto lens provides true optical zoom capabilities.
• Video Recording and Front Camera: Both devices are capable of recording high-quality video, including 4K resolution at 60 frames per second. The iPhone 15 has a 12MP front camera with autofocus, offering clear selfies and video calls. The Galaxy S21 FE 5G features a 32MP front camera, which often uses pixel binning to produce detailed 8MP or 12MP images.
