Galaxy S21 FE 5G • Locked AT&T vs Galaxy Z Fold5 • Unlocked

The expected practical lifespan of a smartphone is influenced by its release timeline, software support, and physical durability features. These two devices, released over a year apart, offer different longevity prospects.

• Software Longevity: The Galaxy S21 FE 5G, launched in early 2022, typically receives 4 years of Android OS updates and 5 years of security updates from its release date. The Galaxy Z Fold5, released in mid-2023, benefits from a later launch, offering an additional year of OS and security updates, extending its software support further into the future.
• Physical Durability: The Galaxy S21 FE 5G features a plastic back, an aluminum frame, and Gorilla Glass Victus on its display, providing a good level of everyday durability and IP68 dust and water resistance. The Galaxy Z Fold5, while also featuring an aluminum frame and Gorilla Glass Victus 2 on its cover screen, introduces a complex foldable display and hinge mechanism. It boasts an IPX8 water resistance rating, meaning it can withstand submersion in fresh water, but it does not have an official dust resistance rating due to its folding nature.
• Repairability: Traditional slab phones like the S21 FE generally offer more straightforward repair processes compared to foldable devices. The Z Fold5's intricate design, with two displays and a hinge, can make repairs more complex and potentially more costly.

Performance is a key aspect for any smartphone, influencing how smoothly applications run and how efficiently tasks are handled. Both devices offer capable performance, though they cater to different demands.

• Processing Power: The Galaxy S21 FE 5G is equipped with a high-end processor from its release year, enabling it to handle demanding applications and multitasking with ease. The Galaxy Z Fold5 features a more recent, top-tier processor, which provides enhanced speed and efficiency, particularly noticeable in intensive gaming or when running multiple applications simultaneously across its larger display.
• Multitasking and RAM: The S21 FE 5G typically comes with 6GB or 8GB of RAM, which is sufficient for most daily tasks and moderate multitasking. The Galaxy Z Fold5, designed for advanced multitasking with its expansive screen, includes 12GB of RAM, allowing for a smoother experience when running several applications side-by-side or switching between them frequently.
• Battery Behavior: The Galaxy S21 FE 5G houses a 4500 mAh battery, which generally provides a full day of use for most users. The Galaxy Z Fold5 has a 4400 mAh battery. Despite a slightly smaller capacity, its more efficient processor helps it achieve comparable or even slightly better battery life in some usage scenarios, though heavy use of the large inner display can lead to more frequent charging.

The display is a primary interaction point, and these two devices offer vastly different visual experiences due to their form factors.

• Display Technology and Clarity: Both phones utilize Dynamic AMOLED 2X display technology, known for vibrant colors, deep blacks, and excellent contrast. The Galaxy S21 FE 5G features a 6.4-inch Full HD+ display, offering sharp visuals for everyday content. The Galaxy Z Fold5, however, boasts a unique dual-screen setup: a 6.2-inch cover display and a large 7.6-inch foldable inner display. The inner display provides a tablet-like experience with a higher resolution, enhancing clarity for detailed content.
• Refresh Rate and Smoothness: Both devices offer a 120Hz refresh rate, contributing to smooth scrolling and fluid animations. The S21 FE 5G's display maintains a consistent 120Hz, while the Z Fold5's adaptive refresh rate can dynamically adjust based on content, optimizing for both smoothness and power efficiency.
• Brightness and Viewing Experience: Both displays offer good brightness levels for outdoor visibility. The Z Fold5's main display can achieve higher peak brightness, which can be beneficial in direct sunlight. The S21 FE provides a traditional smartphone viewing experience, while the Z Fold5's large foldable screen is ideal for immersive media consumption, reading, and productivity tasks, though the crease on the foldable display is visible under certain conditions.

Camera capabilities are a significant factor for many users, and both smartphones offer versatile camera systems for capturing photos and videos.

• Rear Camera System: The Galaxy S21 FE 5G features a triple camera setup with a 12MP main, 12MP ultrawide, and an 8MP telephoto lens with 3x optical zoom. This configuration is capable of capturing detailed photos and offers flexibility for various shooting scenarios. The Galaxy Z Fold5 also has a triple rear camera system, including a 50MP main sensor, a 12MP ultrawide, and a 10MP telephoto lens with 3x optical zoom. The higher resolution main sensor on the Z Fold5 can capture more detail, especially in well-lit conditions.
• Low-Light Performance and Features: Both phones include features like Night Mode to enhance low-light photography, combining multiple exposures for brighter and clearer images. The Z Fold5's more advanced image processing, partly due to its newer processor, can lead to improved results in challenging lighting.
• Video Recording and Front Cameras: Both devices support 4K video recording at 60fps. The S21 FE 5G has a 32MP front camera for high-resolution selfies and video calls. The Z Fold5 has a 10MP camera on its cover display and a 4MP under-display camera on the main foldable screen, offering different options for selfies and video conferencing, with the cover camera generally providing better quality.

Beyond core features, several practical elements contribute to the overall user experience and differentiate these two devices.

• Connectivity and Ports: Both phones support 5G connectivity for fast mobile data. The S21 FE 5G includes Wi-Fi 6 and Bluetooth 5.0. The Z Fold5 offers newer standards like Wi-Fi 6E and Bluetooth 5.3, providing potentially faster and more stable wireless connections. Both devices feature a USB-C port for charging and data transfer and lack a traditional 3.5mm headphone jack.
• Biometric Security: The Galaxy S21 FE 5G uses an optical under-display fingerprint sensor for secure unlocking. The Galaxy Z Fold5 incorporates a side-mounted fingerprint sensor, integrated into the power button. Both also support face recognition.
• Design and Handling: The S21 FE 5G is a conventional slab smartphone, weighing 177g and offering a familiar in-hand feel. The Galaxy Z Fold5, at 253g, is significantly heavier and thicker when folded, but it transforms into a much larger, thinner device when unfolded. Its unique form factor allows for a compact phone that expands into a mini-tablet, impacting portability and one-handed use differently than a traditional phone.
• Build Materials: The S21 FE 5G features a plastic back, which contributes to its lighter weight and can be more resistant to shattering than glass. The Z Fold5 uses more premium materials like Gorilla Glass Victus 2 and an aluminum frame, offering a more robust feel, though the foldable screen itself requires careful handling.
