Scores

Durability

When considering the longevity of these devices, their release timelines and software support policies are key factors.

  • Software Support: The Galaxy S21 5G, having launched with Android 11, is expected to receive operating system updates up to Android 15 and security updates until early 2026. The newer Galaxy Z Flip5, released with Android 13, is slated for four generations of Android OS updates, extending to Android 17, and five years of security updates, continuing through August 2028. This provides the Z Flip5 with a longer period of official software support.
  • Physical Durability: The Galaxy S21 5G features a Gorilla Glass Victus front, an aluminum frame, and a plastic back, along with an IP68 rating for dust and water resistance. The Galaxy Z Flip5 boasts an Armor Aluminum frame and Gorilla Glass Victus 2 on both its cover screen and back panel, coupled with an IPX8 water resistance rating. Its redesigned hinge allows the device to close completely flat, reducing the gap seen in earlier foldable models and potentially enhancing its structural integrity when folded.
  • Practical Lifespan: While both devices offer robust build quality, the Z Flip5's newer components and extended software support suggest a slightly longer practical lifespan for receiving the latest features and security patches.

Performance

The performance of a smartphone is crucial for daily tasks, from app usage to multitasking and gaming.

  • Processing Power: The Galaxy S21 5G is equipped with an octa-core processor, either the Snapdragon 888 or Exynos 2100, depending on the region. The Galaxy Z Flip5 features a more recent octa-core processor, specifically optimized for Galaxy devices. This newer processor in the Z Flip5 generally translates to improved efficiency and faster handling of demanding applications and complex tasks.
  • Memory and Storage: Both devices typically come with 8GB of RAM, which is sufficient for smooth multitasking and app management. For internal storage, the Galaxy S21 5G offers 128GB or 256GB options, while the Galaxy Z Flip5 provides 256GB or 512GB. Neither model includes a microSD card slot for expandable storage.
  • Real-world Responsiveness: Users of the Z Flip5 generally report a very fluid experience, with applications loading quickly and smooth transitions, attributed to its newer processing architecture. The S21 5G also delivers a responsive experience for everyday use and gaming, though the Z Flip5's newer processor offers a performance advantage for future-proofing and the most intensive workloads.

Screen quality

The display is a primary interaction point, and these two devices offer distinct viewing experiences.

  • Display Technology and Size: The Galaxy S21 5G features a 6.2-inch Dynamic AMOLED 2X flat display. The Galaxy Z Flip5, on the other hand, has a 6.7-inch foldable Dynamic AMOLED 2X main screen. The Z Flip5 also includes a 3.4-inch Super AMOLED cover screen, which is significantly larger and more functional than previous Flip models, allowing for more interactions without unfolding the device.
  • Resolution and Clarity: Both main displays offer Full HD+ resolution (2400x1080 pixels for S21 5G, 2640x1080 pixels for Z Flip5), resulting in sharp and clear visuals for typical viewing distances. The pixel density is around 421 ppi for the S21 5G and similar for the Z Flip5's main screen.
  • Brightness and Refresh Rate: Both phones feature an adaptive 120Hz refresh rate, providing smooth scrolling and fluid animations while conserving battery life by adjusting to content. The Z Flip5's main screen can reach a peak brightness of 1750 nits, while the S21 5G reaches 1300 nits, offering good visibility in various lighting conditions.

Audiovisual

Both smartphones offer capable camera systems, but with different strengths and features.

  • Rear Camera Systems: The Galaxy S21 5G features a versatile triple-camera setup on the rear: a 12MP wide-angle lens with optical image stabilization (OIS), a 64MP telephoto lens offering 3x hybrid optical zoom, and a 12MP ultrawide lens. This configuration allows for a range of photographic options, including detailed zoomed shots. The Galaxy Z Flip5 has a dual-camera system on the rear, consisting of a 12MP wide-angle lens with OIS and a 12MP ultrawide lens. It lacks a dedicated telephoto lens, relying on digital zoom for magnification.
  • Photography Performance: The S21 5G is noted for its sharp photos, good dynamic range, and effective telephoto capabilities, with 8K video recording support. The Z Flip5 delivers vibrant and detailed photos, particularly in good lighting, and benefits from its foldable design for unique shooting angles (FlexCam) and high-quality selfies using the main cameras via the cover screen.
  • Front Camera and Audio: Both devices include a 10MP front-facing camera for selfies and video calls. Both also offer stereo speakers for an enhanced audio experience during media consumption.

Miscellaneous

Beyond core features, several practical elements differentiate these two Samsung smartphones.

  • Connectivity: Both the Galaxy S21 5G and Galaxy Z Flip5 support 5G networks, ensuring access to faster mobile data speeds. The S21 5G supports Wi-Fi 6 and Bluetooth 5.0, while the Z Flip5 features Wi-Fi 6 and the slightly newer Bluetooth 5.3, potentially offering more stable and efficient connections with compatible accessories.
  • Ports and Sensors: Both devices utilize a USB-C port for charging and data transfer and notably lack a traditional 3.5mm headphone jack or a microSD card slot for expandable storage. The Galaxy S21 5G incorporates an ultrasonic in-screen fingerprint sensor for biometric authentication. The Galaxy Z Flip5, due to its foldable design, features a side-mounted fingerprint sensor integrated into the power button.
  • Design and Handling: The S21 5G has a conventional slab design, weighing around 169-171g and measuring 151.7 x 71.2 x 7.9 mm. The Z Flip5, while heavier at 187g, offers a unique compact form factor when folded (85.1 x 71.9 x 15.1 mm), making it highly portable. When unfolded, its dimensions are 165.1 x 71.9 x 6.9 mm. The S21 5G has a plastic back, whereas the Z Flip5 uses Gorilla Glass Victus 2 on its exterior.

The Samsung Galaxy S21 5G and Galaxy Z Flip5 cater to different user priorities, each excelling in its own right. The S21 5G is often praised for its robust camera system, reliable performance, and traditional smartphone experience. Users appreciate its consistent performance for everyday tasks and its ability to capture quality photos and videos. Some common criticisms for the S21 5G included its plastic back, which some perceived as less premium than glass, and the removal of the microSD card slot.

The Galaxy Z Flip5 receives acclaim for its innovative, compact foldable design, which enhances portability and offers unique photographic angles through its FlexCam feature. The larger, more functional cover screen is also a significant highlight, allowing for more interactions without unfolding the device. However, user feedback sometimes points to its battery life as an area that could be improved, and the absence of a telephoto lens is a notable difference compared to many traditional flagships.

Users prioritizing a conventional, powerful smartphone with a versatile camera system and a proven track record of performance may find the Galaxy S21 5G well-suited to their needs. Its stable form factor and comprehensive feature set make it a reliable daily driver. Conversely, individuals who value portability, a distinctive design, and creative photography options will likely lean towards the Galaxy Z Flip5. Its ability to fold into a compact size makes it ideal for those who want a device that easily fits into smaller pockets or bags, and its unique features offer a fresh take on smartphone interaction.

For those considering either device, exploring quality-assured refurbished options can provide an eco-friendly alternative, extending the life cycle of these technologies.
