Galaxy S21+ 5G vs Galaxy Z Fold5

The Samsung Galaxy S21+ 5G, released in January 2021, is a traditional slab-style smartphone, offering a familiar and robust design. In contrast, the Samsung Galaxy Z Fold5, launched in August 2023, represents a significant departure with its innovative foldable form factor. The primary distinction lies in the Z Fold5's ability to transform from a compact smartphone into a larger, tablet-like device, while the S21+ 5G provides a consistent, single-screen experience. Both devices operate on the Android platform, offering access to a vast ecosystem of applications and services, though they differ in their approach to user interaction and display technology.

When considering the practical lifespan of these devices, their release timelines and software support policies are key factors. The Galaxy S21+ 5G, having been released in January 2021, has received its promised four major Android OS updates, concluding with Android 15, and its security updates are expected to transition to a quarterly schedule after January 2026. The Galaxy Z Fold5, released in August 2023, benefits from a more recent launch, ensuring major Android OS upgrades up to Android 17 and security updates until August 2028.

• Software Longevity: The Galaxy Z Fold5 offers a longer period of guaranteed major OS and security updates due to its newer release date, providing extended software support compared to the S21+ 5G.
• Physical Durability: The S21+ 5G features a traditional glass and aluminum build with Gorilla Glass Victus, offering a high degree of resistance to drops and scratches. The Z Fold5, while featuring Gorilla Glass Victus 2 on its cover screen and back, has a foldable inner display that, while more robust than earlier foldable generations, requires careful handling and lacks a dust resistance rating.
• Repairability: The Galaxy S21+ 5G generally has a moderate repairability score, with some components like the battery being glued in place. The Z Fold5's complex folding mechanism and dual-screen setup can make repairs, especially for the inner display, more intricate and potentially more costly.

Both devices deliver capable performance for their respective generations, handling daily tasks and demanding applications efficiently. The differences in their internal components translate to varying levels of responsiveness and multitasking capabilities.

• Everyday Responsiveness: The Galaxy S21+ 5G provides smooth navigation and quick app launches, suitable for general use and moderate multitasking. The Galaxy Z Fold5, with its more recent internal architecture and increased RAM, offers a noticeably snappier experience, particularly when running multiple demanding applications simultaneously or engaging in intensive gaming.
• Multitasking Efficiency: The S21+ 5G, equipped with 8GB of RAM, manages several open applications competently. The Z Fold5, featuring 12GB of RAM, excels in multitasking, allowing users to seamlessly switch between numerous apps and utilize its larger screen for split-screen productivity without significant slowdowns.
• Storage Options: The Galaxy S21+ 5G is available with 128GB or 256GB of internal storage. The Galaxy Z Fold5 offers more expansive storage configurations, starting at 256GB and extending to 512GB or 1TB, catering to users with larger digital libraries or extensive app collections.
• Battery Behavior: The S21+ 5G, with its 4800 mAh battery, is generally reported by users to provide a full day of heavy use and potentially two days with lighter usage. The Z Fold5, housing a 4400 mAh battery, offers decent battery life, often lasting around 1.5 days with typical usage, which is commendable given its dual-screen functionality.

The display experience is a primary differentiator between these two Samsung smartphones, with one offering a traditional flat panel and the other a versatile folding screen.

• Display Technology and Clarity: Both devices feature Dynamic AMOLED 2X displays, known for vibrant colors and deep blacks. The S21+ 5G has a 6.7-inch FHD+ (1080 x 2400) display, providing clear visuals for everyday content. The Z Fold5 offers a 6.2-inch cover display with HD+ resolution and a larger 7.6-inch foldable main display with a QXGA+ (2176 x 1812) resolution, delivering a more expansive and detailed viewing area when unfolded.
• Brightness and Refresh Rate: Both phones support a 120Hz refresh rate for smooth scrolling and animations. The Z Fold5's displays can reach a higher peak brightness of 1750 nits, offering improved visibility in bright outdoor conditions compared to the S21+ 5G's 1300 nits peak brightness.
• Viewing Experience: The S21+ 5G provides a consistent, high-quality flat-screen experience. The Z Fold5's main display, when unfolded, offers a tablet-like canvas ideal for media consumption, reading, and multitasking, though a subtle crease is present and can be noticeable under certain lighting or when touched.

Both the Galaxy S21+ 5G and the Galaxy Z Fold5 are equipped with versatile camera systems designed to capture a range of photographic and videographic content, though with some generational advancements in the newer foldable.

• Rear Camera System: The Galaxy S21+ 5G features a triple camera setup with a 12MP main sensor, a 64MP telephoto lens offering 3x hybrid optical zoom, and a 12MP ultrawide lens. The Galaxy Z Fold5 also has a triple rear camera system, comprising a 50MP main sensor, a 10MP telephoto lens with 3x optical zoom, and a 12MP ultrawide lens. Both systems are capable of producing vibrant images with good detail in favorable lighting.
• Low-Light and Video Performance: The S21+ 5G delivers improved low-light performance over its predecessors and offers video recording up to 8K at 24fps. The Z Fold5's larger main sensor generally provides better light gathering capabilities, contributing to enhanced low-light photography, and also supports 8K video recording at 24fps.
• Front-Facing Cameras: The S21+ 5G has a 10MP front camera. The Z Fold5 features a 10MP camera on its cover screen and a 4MP under-display camera on the main foldable screen, with the latter being more suited for video calls than high-quality selfies.
• Audio Experience: Both devices offer stereo speakers for media consumption. The Z Fold5's larger unfolded screen can enhance the immersive audio-visual experience for content viewing.
