Galaxy S21 5G Vs Galaxy S23

The Samsung Galaxy S21 5G, released in January 2021, and the Samsung Galaxy S23, launched in February 2023, are both flagship Android smartphones from Samsung's popular S series. While they share a similar design philosophy and operate on the Android platform, the Galaxy S23 introduces advancements in processing power, camera technology, and display brightness, reflecting two years of technological evolution.

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

• Release and Software Support: The Galaxy S21 5G was released in January 2021, initially running Android 11. It typically receives three major Android OS updates and four years of security updates, meaning its major OS support likely concluded around Android 14, with security updates potentially ending in early 2025. In contrast, the Galaxy S23, launched with Android 13 in February 2023, is promised four major OS updates (up to Android 17) and five years of security updates, extending its support until at least 2028.
• Physical Durability: Both models feature an IP68 rating for dust and water resistance, allowing submersion up to 1.5 meters for 30 minutes. The Galaxy S21 5G uses Corning Gorilla Glass Victus for screen protection, while the Galaxy S23 upgrades to Gorilla Glass Victus 2 on both the front and back, offering enhanced scratch and drop resistance.
• Repairability: The Galaxy S21 5G received a repairability score of around 7.5 out of 10, noted for being relatively easy to disassemble, though its battery was secured with strong adhesive. The Galaxy S23, particularly the Ultra model, has shown improvements in repairability, with features like battery pull tabs simplifying battery replacement, contributing to a higher repairability rating in some assessments.

The performance of a smartphone significantly impacts daily usage, from app responsiveness to demanding tasks like gaming.

• Processing Power: The Galaxy S21 5G is powered by a processor that handles everyday applications and multitasking efficiently. The Galaxy S23 features a newer, more advanced processor designed specifically for Galaxy devices, which provides a noticeable boost in overall speed and efficiency. This translates to faster app loading times, smoother transitions, and more capable handling of intensive applications and graphics-heavy games.
• Battery Behavior: The Galaxy S21 5G houses a 4000 mAh battery. The Galaxy S23 has a slightly smaller 3900 mAh battery. However, due to the newer processor's improved power efficiency, the Galaxy S23 often delivers comparable or even extended battery life in real-world usage scenarios, allowing many users to comfortably get through a full day.
• Storage and Responsiveness: Both devices offer 8GB of RAM, which supports smooth multitasking. Storage options for both include 128GB and 256GB. The Galaxy S23 also offers a 512GB option, and its 256GB and 512GB variants utilize a newer, faster storage technology (UFS 4.0) compared to the 128GB variant (UFS 3.1) and the S21 5G, which can result in quicker data access and app launches.

The display is a primary interface for smartphone interaction, and both models offer high-quality viewing experiences with some notable differences.

• Display Technology and Clarity: Both the Galaxy S21 5G and Galaxy S23 feature Dynamic AMOLED 2X displays, known for vibrant colors, deep blacks, and excellent contrast. Both provide a Full HD+ resolution (2400x1080 for S21 5G, 2340x1080 for S23), resulting in sharp and clear visuals for everyday content consumption.
• Brightness and Outdoor Visibility: The Galaxy S21 5G offers a peak brightness of around 1300 nits, providing good visibility in various lighting conditions. The Galaxy S23 significantly enhances this with a peak brightness of up to 1750 nits, making it more comfortable to view content outdoors or in brightly lit environments.
• Refresh Rate and Smoothness: Both devices support an adaptive refresh rate of up to 120Hz, which allows for smooth scrolling and fluid animations. This adaptive technology helps conserve battery by lowering the refresh rate when high speed is not needed. The screen sizes are also very similar, with the S21 5G at 6.2 inches and the S23 at 6.1 inches, offering a compact and manageable viewing experience.

The camera systems on both the Galaxy S21 5G and Galaxy S23 are designed to capture high-quality photos and videos, with the newer model offering refinements.

• Rear Camera System: The Galaxy S21 5G features a versatile triple-camera setup: a 12MP wide-angle lens, a 12MP ultra-wide lens, and a 64MP telephoto lens with 3x hybrid optical zoom. The Galaxy S23 also has a triple-camera system, but with a 50MP wide-angle main sensor, a 12MP ultra-wide lens, and a 10MP telephoto lens with 3x optical zoom. The S23's larger main sensor and improved image processing contribute to better detail and color accuracy, especially in challenging lighting.
• Low-Light and Video Performance: Both phones perform well in good lighting. The Galaxy S23 shows notable improvements in low-light photography, capturing more detail and maintaining better color balance due to enhanced AI processing and a more capable sensor. For video, the S21 5G can record up to 8K at 24 frames per second (fps). The S23 elevates this to 8K at 30fps, offering smoother high-resolution video capture.
• Front Camera and Audio: Both devices feature capable front-facing cameras for selfies and video calls. The S21 5G has a 10MP front camera, while the S23 has a 12MP front camera, both delivering sharp images with good dynamic range. Both phones also include stereo speakers, providing a more immersive audio experience for media consumption.
