• Gaming and Demanding Apps: Users will experience improved performance in graphics-intensive games and demanding applications on the Galaxy S23, with better thermal management contributing to sustained performance during extended use. While the S21 Plus 5G still offers capable performance for everyday tasks and many games, the S23 provides a more fluid and powerful experience.
• Battery Behavior: Despite the Galaxy S23 having a smaller battery capacity (3900 mAh) compared to the S21 Plus 5G (4800 mAh), the S23 often delivers comparable or even better real-world battery life due to its more power-efficient processor and optimized software. The S21 Plus 5G generally offers good battery life for moderate use, often lasting a full day.
• Storage Options: Both devices offer 128GB and 256GB internal storage options. The Galaxy S23 also introduces a 512GB option, and for its 256GB and higher variants, it utilizes faster UFS 4.0 storage, which can improve app loading and data transfer speeds compared to the S21 Plus 5G's UFS 3.1.

Both smartphones offer high-quality displays, but there are differences in size, brightness, and overall viewing experience.

• Display Technology: Both the Galaxy S21 Plus 5G and the Galaxy S23 feature Dynamic AMOLED 2X displays, known for vibrant colors, deep blacks, and excellent contrast.
• Size and Resolution: The Galaxy S21 Plus 5G has a larger 6.7-inch display with a 1080 x 2400 pixel resolution. The Galaxy S23 features a more compact 6.1-inch display with a 1080 x 2340 pixel resolution. While the S21 Plus 5G offers more screen real estate, the S23's smaller screen results in a slightly higher pixel density, contributing to sharp visuals.
• Brightness and Outdoor Visibility: The Galaxy S23 offers significantly higher peak brightness, reaching up to 1750 nits, which greatly enhances outdoor visibility and HDR content viewing compared to the S21 Plus 5G's 1300 nits peak brightness.
• Refresh Rate: Both models feature an adaptive 120Hz refresh rate, providing smooth scrolling and fluid animations. The S23's display can dynamically adjust its refresh rate more efficiently, potentially contributing to better power management.

The camera systems on both devices are capable, but the newer Galaxy S23 brings notable enhancements, particularly in image processing and low-light performance.

• Main Camera: The Galaxy S23 features a 50 MP main sensor, which captures detailed images with improved low-light performance and dynamic range. The S21 Plus 5G has a 12 MP main sensor that still produces good quality photos in well-lit conditions.
• Telephoto and Ultrawide: The S23 includes a 10 MP telephoto lens with 3x optical zoom and a 12 MP ultrawide lens. The S21 Plus 5G offers a 64 MP telephoto lens with 1.1x optical zoom and 3x hybrid zoom, alongside a 12 MP ultrawide lens. The S23's dedicated optical zoom lens often provides clearer zoomed-in shots.
• Low-Light Photography: The Galaxy S23 generally excels in low-light conditions, producing brighter and more detailed images with less noise, a common area of improvement in newer smartphone cameras. The S21 Plus 5G performs adequately in low light, but may show more noise and less detail compared to the S23.
