Galaxy S21 5G Vs Google Pixel 9 Pro Fold

The Samsung Galaxy S21 5G (2021) and the Google Pixel 9 Pro Fold (2024) represent two distinct eras and philosophies in smartphone design. While the Galaxy S21 is a classic, compact flagship smartphone designed for traditional use, the Pixel 9 Pro Fold is a modern foldable device that transforms from a standard phone into a small tablet. Both devices operate on the Android ecosystem, though they offer different user interfaces and software priorities.

The primary differentiator between these two models is their form factor: the Galaxy S21 prioritises portability and one-handed ergonomics, whereas the Pixel 9 Pro Fold focuses on maximum screen real estate and multitasking capabilities. This comparison explores how these differences impact daily usage, longevity, and overall performance for different types of users.

The age gap between these two devices significantly influences their remaining software support and physical resilience over time.

• Software Longevity: The Galaxy S21, having launched in 2021, is nearing the end of its major operating system update cycle, though it may continue to receive security patches for a limited time. In contrast, the Pixel 9 Pro Fold was released with a commitment to seven years of software and security updates, ensuring it remains current and functional well into the next decade.
• Physical Durability: The Galaxy S21 features a flat display and a polycarbonate back, which is generally more resistant to impact than glass. The Pixel 9 Pro Fold utilizes a complex hinge mechanism and a flexible internal screen; while it is built with modern materials, the moving parts and the nature of foldable screens require more careful handling to avoid long-term wear.
• Repairability: Standard smartphones like the Galaxy S21 are widely understood by repair technicians, making battery or screen replacements relatively straightforward. The Pixel 9 Pro Fold, due to its intricate folding design and dual-screen setup, often requires specialised service and may be more complex to maintain over several years of use.

Despite the generational gap, both devices provide a responsive experience, though they are optimized for different types of workloads.

• Multitasking and RAM: The Pixel 9 Pro Fold is specifically engineered to handle complex multitasking, allowing users to run multiple applications simultaneously on its expansive internal screen without experiencing lag. This is supported by a high amount of temporary memory that ensures background tasks remain active. The Galaxy S21 is optimized for single-task efficiency, handling everyday apps smoothly but with less headroom for intensive multi-window use.
• Battery Behaviour: The Galaxy S21 features a battery capacity suited for a full day of moderate use, such as browsing and messaging. The Pixel 9 Pro Fold has a larger battery to power its two screens, but users will find that frequent use of the large internal display will consume power more rapidly than using the smaller external screen.
• System Responsiveness: While the Galaxy S21 remains snappy for standard social media and web browsing, the Pixel 9 Pro Fold offers a more fluid experience in demanding mobile games and AI-assisted tasks. The newer internal hardware in the Pixel ensures that the system feels faster when processing large files or launching heavy applications.

The most striking difference between these devices lies in their display technology and the sheer amount of viewing area available to the user.

• Display Versatility: The Galaxy S21 offers a high-quality 6.2-inch AMOLED screen that provides deep blacks and vibrant colours in a compact frame. The Pixel 9 Pro Fold provides a dual-screen experience, featuring a standard-sized outer display and a massive 8-inch internal folding screen. This larger canvas is particularly beneficial for users who frequently read long documents or watch videos.
• Brightness and Outdoor Use: Both devices feature high peak brightness levels, making them legible in outdoor environments. However, the Pixel 9 Pro Fold utilizes newer panel technology that can reach higher brightness levels, which helps maintain clarity and colour accuracy even under direct, harsh sunlight.
• Refresh Rates and Smoothness: Both models support a 120Hz refresh rate, which ensures that scrolling through menus and animations looks fluid. The Pixel 9 Pro Fold uses more advanced variable refresh rate technology, which can slow down the screen when it is static to help manage battery consumption more effectively than the older system in the S21.

Photography and media consumption are handled differently, with the Pixel focusing on software-driven processing and the S21 offering a reliable traditional setup.

• Camera Versatility: The Galaxy S21 includes a dedicated high-resolution telephoto lens that is excellent for capturing detailed shots from a distance. The Pixel 9 Pro Fold uses a combination of modern sensors and advanced software processing to deliver consistent, high-quality images across its wide, ultra-wide, and telephoto lenses, with a particular focus on natural skin tones.
• Low-Light Performance: Users will find that the Pixel 9 Pro Fold captures more detail and less noise in dark environments thanks to its newer sensor technology and Google's specialized night-mode processing. The Galaxy S21 remains capable in low light but may show more grain in very dark scenes compared to the newer model.
• Video and Audio Quality: The Pixel 9 Pro Fold excels in video recording with enhanced electronic stabilisation and clear microphone pickup, making it a strong choice for video calls and content creation. The Galaxy S21 provides a balanced audio experience with stereo speakers that are clear and loud enough for everyday media consumption.
