Galaxy S21 FE 5G vs Galaxy Z Flip5

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 within the Android ecosystem. While both devices offer a comprehensive Android experience, their primary differentiation lies in their form factor: the S21 FE is a traditional slab smartphone, whereas the Z Flip5 features a unique foldable clamshell design. This fundamental difference influences aspects from screen utility to overall portability and user interaction.

When considering the long-term usability of these devices, their release timelines and software support policies are key factors.

• Software Longevity: The Galaxy S21 FE 5G, launched with Android 12, is expected to receive four major Android OS updates, extending its support up to Android 16. It also receives security updates, initially monthly, then quarterly, until at least the end of 2025, with potential for further updates for critical vulnerabilities. The Galaxy Z Flip5, released with Android 13, is also committed to four generations of Android OS upgrades, meaning it will receive updates up to Android 17, and five years of security updates. This gives the Z Flip5 a longer projected software lifespan due to its later release.
• Physical Durability: The S21 FE features an IP68 rating for dust and water resistance and Gorilla Glass Victus for screen protection. The Z Flip5 boasts an IPX8 water resistance rating, indicating protection against submersion, but it does not have an official dust resistance rating. Its main foldable screen uses Ultra Thin Glass, while the cover screen is protected by Gorilla Glass Victus 2. The Z Flip5's hinge mechanism is designed for durability, allowing it to fold flat without a gap.
• Practical Lifespan: Both devices are built to offer several years of reliable use. The S21 FE's traditional design may offer a perception of robustness for some users, while the Z Flip5's folding mechanism, though improved, introduces a different set of considerations regarding the longevity of the flexible display and hinge with repeated use.

The performance of both smartphones is designed to handle daily tasks efficiently, though they feature different generations of internal components.

• Processing Power: The Galaxy S21 FE 5G is equipped with a processor that handles demanding applications and multitasking smoothly, providing a responsive user experience for most activities, including gaming. The Galaxy Z Flip5, being a newer device, incorporates a more current-generation processor, which contributes to enhanced overall system responsiveness and power efficiency. This allows the Z Flip5 to manage intensive tasks and complex applications with greater ease and potentially better sustained performance.
• Battery Behavior: The S21 FE houses a 4500 mAh battery, which generally provides a full day of use for many users, though some reports indicate it may require more frequent charging with heavy usage. The Z Flip5 has a smaller 3700 mAh battery. However, its more efficient processor helps optimize battery life, with users reporting nearly a full day of use, though heavy users might still find themselves seeking a charger before day's end.
• Storage and Multitasking: Both devices offer various internal storage options, with the S21 FE available in 128GB and 256GB configurations, and the Z Flip5 in 256GB and 512GB. The S21 FE typically comes with 6GB or 8GB of RAM, while the Z Flip5 consistently features 8GB of RAM. This difference in RAM can influence the number of applications that can remain open and active in the background without needing to reload.

The display experience is a significant differentiator, particularly due to the Z Flip5's unique folding design and dual-screen setup.

• Display Technology and Clarity: The Galaxy S21 FE features a 6.4-inch Dynamic AMOLED 2X display with a Full HD+ resolution (2340 x 1080 pixels), offering vibrant colors and deep blacks. The Galaxy Z Flip5's main internal display is a 6.7-inch Foldable Dynamic AMOLED 2X with a Full HD+ resolution (2640 x 1080 pixels), providing a similar visual quality when unfolded. The Z Flip5 also includes a 3.4-inch Super AMOLED cover display (720 x 748 pixels) that allows for quick interactions without opening the device.
• Brightness and Refresh Rate: Both phones offer a smooth viewing experience with a 120Hz adaptive refresh rate on their main displays, contributing to fluid scrolling and animations. The S21 FE's display can reach decent brightness levels for outdoor visibility. The Z Flip5's main screen also offers strong brightness, and its cover screen is notably bright, enhancing usability in various lighting conditions.
• Viewing Experience: The S21 FE provides a consistent, expansive viewing area. The Z Flip5's foldable screen, while offering a large display when open, has a visible crease where it folds, which some users may notice, particularly on darker backgrounds. The Z Flip5's cover screen offers a convenient, compact way to check notifications, control media, and use widgets, adding a layer of functionality not present on the S21 FE.

Both devices offer capable camera systems, but their configurations and practical applications differ, especially concerning their form factors.

• Rear Camera Systems: The Galaxy S21 FE features a versatile triple-camera setup, including a 12MP main lens, a 12MP ultrawide lens, and an 8MP telephoto lens with 3x optical zoom. This dedicated telephoto lens allows for clear zoomed-in shots. The Galaxy Z Flip5 has a dual-camera system on its rear, comprising a 12MP main lens and a 12MP ultrawide lens. It lacks a dedicated telephoto lens, relying on digital zoom.
• Photography Performance: The S21 FE delivers good image quality in various conditions, with improved low-light performance compared to its predecessor. The Z Flip5 also produces quality photos with sharp details and vibrant colors, performing well in low-light scenarios. Its unique folding design allows for creative shooting angles and hands-free photography using the main cameras for selfies.
• Front Camera and Video: The S21 FE is equipped with a 32MP front-facing camera, capable of capturing detailed selfies. The Z Flip5 has a 10MP front camera located on the main display, but its foldable nature allows users to utilize the higher-quality rear cameras for selfies, aided by the cover screen for framing. Both devices are capable of recording high-quality video, including 4K at 60fps.
• Audio Experience: Both phones offer stereo speakers for media consumption. The S21 FE provides good call quality. The Z Flip5's dual-speaker system delivers clear vocals and defined treble.
