Galaxy S21 FE 5G • Locked AT&T vs Galaxy Z Flip5 • Unlocked

The Samsung Galaxy S21 FE 5G, released in January 2022, and the Samsung Galaxy Z Flip5, launched in August 2023, represent distinct approaches to smartphone design and functionality. While the S21 FE offers a traditional, flat-screen experience, the Z Flip5 introduces a foldable clamshell design with a prominent external display. These differences cater to varying user preferences, from those seeking a conventional and robust device to those prioritizing portability and innovative interaction.

When considering the long-term usability of a smartphone, factors like release date, software support, and physical resilience are key. The Galaxy S21 FE 5G and Galaxy Z Flip5 offer different profiles in these areas.

• Release Timeline and Software Support: The Galaxy S21 FE 5G, released in January 2022, launched with Android 12 and is expected to receive four generations of Android OS upgrades and five years of security updates, likely extending its support until early 2027 for security patches. The Galaxy Z Flip5, released in August 2023, launched with Android 13 and is also promised four generations of OS upgrades and five years of security updates, meaning its software support will extend further, potentially until late 2028.
• Physical Durability: The Galaxy S21 FE 5G features a traditional slab design with Gorilla Glass Victus on the front and a plastic back, along with an IP68 rating for dust and water resistance. The Galaxy Z Flip5, with its foldable design, uses Gorilla Glass Victus 2 on its cover screen and back panel, an Armor Aluminum frame, and an IPX8 water resistance rating, meaning it can withstand submersion in water but is not rated for dust resistance. The foldable screen itself is made of ultra-thin glass (UTG) covered with a plastic layer.
• Repairability and Practical Lifespan: While both devices are designed for longevity, the Z Flip5's foldable nature introduces additional mechanical components, such as the hinge, which has been redesigned for improved durability. User reports for the Z Flip5 indicate that while the hinge is robust, the inner screen protector can peel over time, and some users have reported minor hardware issues. The S21 FE, with its more conventional construction, generally presents fewer unique repair challenges related to its form factor.

The performance of a smartphone is crucial for daily tasks, from app usage to demanding games. Both the Galaxy S21 FE 5G and Galaxy Z Flip5 deliver capable performance, though they are equipped with different generations of internal components.

• Processing Power: The Galaxy S21 FE 5G is powered by a processor that handles multitasking and demanding applications smoothly, offering a responsive experience for most users. The Galaxy Z Flip5, being a newer device, features a more advanced processor designed for enhanced efficiency and speed, resulting in quicker app loading times and smoother performance in graphically intensive games and complex tasks.
• Multitasking and Responsiveness: Both devices come with 8 GB of RAM in many configurations, allowing for efficient multitasking. The Z Flip5's newer processor contributes to a slightly more fluid overall system responsiveness, particularly when switching between numerous applications or running several in the background.
• Battery Behavior: The Galaxy S21 FE 5G is equipped with a 4500 mAh battery, which generally provides a full day of use for many users. The Galaxy Z Flip5 has a smaller 3700 mAh battery. Despite the smaller capacity, the Z Flip5's more efficient processor and software optimizations allow it to achieve comparable, and in some tests, even longer battery life than devices with larger batteries, often lasting a full day with typical usage. However, heavy users of the Z Flip5 might find themselves needing to charge more frequently.

The display is a primary interface for any smartphone, and both the Galaxy S21 FE 5G and Galaxy Z Flip5 offer vibrant viewing experiences, albeit with distinct form factors.

• Display Technology and Clarity: The Galaxy S21 FE 5G features a 6.4-inch Dynamic AMOLED 2X display with a Full HD+ resolution (2340 x 1080 pixels), providing deep blacks and vibrant colors. The Galaxy Z Flip5 has a 6.7-inch Foldable Dynamic AMOLED 2X main display with a Full HD+ resolution (2640 x 1080 pixels) when unfolded. Both offer excellent clarity for viewing content.
• Refresh Rate and Smoothness: Both devices boast an adaptive 120Hz refresh rate on their main displays, ensuring smooth scrolling and fluid animations. This high refresh rate enhances the user experience, particularly during gaming or browsing.
• Unique Display Features: The Z Flip5's standout feature is its 3.4-inch Super AMOLED cover display, which offers a resolution of 720 x 748 pixels. This larger external screen allows users to interact with widgets, notifications, and even take selfies without unfolding the phone, adding a layer of convenience and unique functionality. The S21 FE offers a continuous, uninterrupted display experience.

Photography capabilities are a significant consideration for many smartphone users, and both the Galaxy S21 FE 5G and Galaxy Z Flip5 provide capable camera systems for capturing moments.

• Rear Camera Systems: The Galaxy S21 FE 5G features a versatile triple-camera setup on the rear, including a 12MP wide lens, a 12MP ultrawide lens, and an 8MP telephoto lens with 3x optical zoom. This telephoto lens allows for clearer zoomed-in shots. The Galaxy Z Flip5 has a dual-camera system on the rear, consisting of a 12MP wide-angle lens and a 12MP ultrawide lens.
• Photography Performance: The S21 FE's camera system is known for producing detailed and vibrant photos in various conditions, with features like Night Mode available on all lenses, including the front camera. The Z Flip5's cameras, while technically similar to its predecessor, benefit from improved processing, delivering lively photos with good color and dynamic range in daylight. Its unique form factor allows for hands-free photography using Flex Mode.
• Video Recording and Front Camera: Both devices support 4K video recording at 60 frames per second. The S21 FE has a high-resolution 32MP front camera, suitable for detailed selfies and video calls. The Z Flip5 features a 10MP front camera on its main display, but its larger cover screen allows users to utilize the higher-quality rear cameras for selfies and video calls, offering more flexibility.
