Galaxy S21 5G Vs Galaxy S23+

The Samsung Galaxy S21 5G, released in January 2021, and the Samsung Galaxy S23 Plus, launched in February 2023, are both premium Android smartphones from Samsung's flagship S series. While they share the core Android operating system and Samsung's One UI interface, the S23 Plus introduces advancements in processing power, camera capabilities, and overall device longevity due to its more recent release.

The expected practical lifespan of a smartphone is significantly influenced by its release date and the manufacturer's software support policy. These two models, separated by two years, offer different outlooks on long-term usability.

• Software Updates: The Galaxy S21 5G, having launched with Android 11, has likely concluded its major operating system updates, typically receiving four generations of Android updates. The Galaxy S23 Plus, released with Android 13, is expected to receive major OS updates until Android 17 and security updates until February 2028, offering a longer period of current software support.
• Build Materials: The Galaxy S21 5G features a polycarbonate back, which can be more resistant to shattering than glass, paired with Gorilla Glass Victus on the front. The Galaxy S23 Plus upgrades to Gorilla Glass Victus 2 on both the front and back, along with an Armor Aluminum frame, providing enhanced scratch and drop protection.
• Repairability: The Galaxy S21 5G has been noted for being relatively straightforward to disassemble, with some modular components, contributing to a repairability score of around 7.5 out of 10 by some assessments. However, the battery often requires strong adhesive removal. Information on the S23 Plus's repairability suggests a similar approach with glued components, making battery replacement a common challenge for both.

Performance differences between the two devices are notable, primarily due to the generational leap in internal components, impacting everything from app responsiveness to battery efficiency.

• Processing Power: The Galaxy S23 Plus features a more advanced processor, which translates to smoother operation, faster app loading times, and more efficient handling of demanding applications and multitasking. Users will experience a noticeable difference in responsiveness, especially with graphically intensive games or complex productivity tasks.
• Battery Endurance: The Galaxy S23 Plus houses a larger 4700 mAh battery compared to the 4000 mAh battery in the Galaxy S21 5G. Combined with a more power-efficient processor, the S23 Plus generally offers significantly longer battery life, with many users reporting it can comfortably last through a full day, and sometimes even two, of moderate use. The S21 5G's battery life was considered adequate for a full day for many users, but heavy usage often required more frequent charging.
• Storage and RAM: Both models typically come with 8GB of RAM, which is sufficient for smooth multitasking. Storage options for both devices generally start at 128GB, with 256GB and 512GB variants also available for the S23 Plus, offering ample space for apps, photos, and videos.

Both smartphones offer high-quality display experiences, but the newer model brings enhancements in brightness and overall viewing comfort.

• Display Technology and Size: Both devices feature Dynamic AMOLED 2X displays with a 120Hz refresh rate, providing fluid scrolling and vibrant colors. The Galaxy S21 5G has a 6.2-inch display, offering a more compact form factor. The Galaxy S23 Plus features a larger 6.6-inch display, providing more screen real estate for media consumption and productivity.
• Brightness and Clarity: While both screens offer excellent clarity with a Full HD+ resolution (1080 x 2400 pixels for S21 5G, 1080 x 2340 pixels for S23 Plus), the Galaxy S23 Plus boasts a higher peak brightness of 1750 nits, compared to the S21 5G's 1300 nits. This makes the S23 Plus's display more visible in bright outdoor conditions.
• Viewing Experience: The adaptive 120Hz refresh rate on both phones ensures smooth visuals. The larger screen of the S23 Plus enhances the immersive experience for videos and games, while the S21 5G's smaller size makes it easier for one-handed use.

The camera systems on both devices are capable, but the Galaxy S23 Plus benefits from newer sensor technology and improved image processing.

• Rear Camera System: The Galaxy S21 5G features a triple camera setup with a 12MP main sensor, a 12MP ultrawide sensor, and a 64MP telephoto lens offering 3x hybrid optical zoom. The Galaxy S23 Plus also has a triple camera system, but with a 50MP main sensor, a 12MP ultrawide, and a 10MP telephoto lens with 3x optical zoom. The S23 Plus's larger main sensor and improved processing contribute to better detail and color accuracy.
• Low-Light and Video Performance: The Galaxy S23 Plus shows improvements in low-light photography, often producing brighter and more detailed images. Video recording on the S23 Plus also sees enhancements, including better stabilization and more natural color rendition, with the ability to record 8K video at 30fps, an improvement over the S21 5G's 8K at 24fps.
• Front Camera: The S21 5G includes a 10MP front camera, while the S23 Plus upgrades to a 12MP front camera. The S23 Plus's front camera also benefits from improved processing, leading to crisp and well-lit selfies.
