Galaxy S21 Ultra 5G Vs Galaxy S23+

The Samsung Galaxy S21 Ultra 5G, released in January 2021, and the Samsung Galaxy S23 Plus, launched in February 2023, represent different generations within Samsung's premium smartphone lineup. While both devices offer a high-end Android experience, the S23 Plus introduces advancements in processing power, display brightness, and battery efficiency, alongside a refined camera system. Both operate on the Android platform, with Samsung's One UI overlay, providing a consistent user experience across the brand.

When considering the long-term usability of these devices, their release timelines and software support are key factors.

• Release Timeline: The Galaxy S21 Ultra 5G, released in January 2021, is an older model compared to the Galaxy S23 Plus, which launched in February 2023. This two-year difference directly impacts their remaining software support.
• OS Support Duration: Samsung typically provides several years of major Android operating system updates and extended security updates for its flagship devices. The Galaxy S21 Ultra 5G has likely received its final major OS updates by early 2026, with security updates continuing for a period. The Galaxy S23 Plus, being newer, is expected to receive major OS updates for a longer duration, potentially until 2028, offering a more extended period of current software features and security patches.
• Practical Lifespan: Both phones feature robust builds with IP68 water and dust resistance, contributing to their physical durability. The S23 Plus benefits from newer Gorilla Glass Victus 2 on its front and back, offering enhanced scratch and drop protection compared to the Gorilla Glass Victus on the S21 Ultra 5G.

The performance of a smartphone is crucial for daily tasks, from app usage to demanding games and multitasking.

• Processing Capabilities: The Galaxy S21 Ultra 5G handles demanding applications and multitasking smoothly, providing a responsive user experience for most tasks. The Galaxy S23 Plus, featuring a newer generation processor, offers enhanced performance, particularly noticeable in graphically intensive games and when running multiple complex applications simultaneously. This newer processor also contributes to improved power efficiency.
• System Responsiveness: Both devices deliver a fluid and responsive interface. However, the S23 Plus exhibits a slight edge in overall system snappiness and faster app loading times due to its more advanced internal components. Users upgrading from older devices will likely perceive a more significant improvement in the S23 Plus's responsiveness.
• Storage and RAM: The S21 Ultra 5G was available with 12GB or 16GB of RAM and storage options up to 512GB. The S23 Plus comes with 8GB of RAM and storage options up to 512GB. While the S21 Ultra 5G offered higher RAM configurations, the S23 Plus's more efficient processor and optimized software ensure smooth multitasking and app management, making its 8GB RAM configuration highly capable.
• Battery Behavior: The Galaxy S21 Ultra 5G is equipped with a 5000 mAh battery, generally providing a full day of use for most users, though heavy usage might necessitate a midday charge. The Galaxy S23 Plus has a 4700 mAh battery, which is slightly smaller, but its more power-efficient processor and display technology often result in excellent battery life, with many users reporting it can comfortably last through a full day, and sometimes even two, under typical usage.

The display is a primary interaction point, and both phones offer high-quality viewing experiences with distinct characteristics.

• Display Technology and Size: Both devices feature Dynamic AMOLED 2X displays, known for deep blacks and vibrant colors. The Galaxy S21 Ultra 5G has a larger 6.8-inch display, while the Galaxy S23 Plus features a 6.6-inch display.
• Resolution and Clarity: The S21 Ultra 5G boasts a higher QHD+ resolution (3200 x 1440 pixels), resulting in a very sharp image. The S23 Plus has an FHD+ resolution (2340 x 1080 pixels). While the S21 Ultra 5G technically offers a higher pixel density, the S23 Plus's FHD+ resolution on its 6.6-inch screen still provides excellent clarity for everyday viewing, with many users finding the difference in sharpness not significantly noticeable in practical use.
• Brightness Levels: The S21 Ultra 5G offers a peak brightness of 1500 nits. The S23 Plus improves upon this with a peak brightness of 1750 nits, making it exceptionally bright and highly visible even in direct sunlight.
• Refresh Rate: Both phones feature an adaptive 120Hz refresh rate for smooth scrolling and animations. The S21 Ultra 5G can dynamically adjust its refresh rate from 10Hz to 120Hz, optimizing for both smoothness and power efficiency. The S23 Plus adjusts its refresh rate from 48Hz to 120Hz, which is still smooth but less dynamic than the S21 Ultra 5G's range.

Both smartphones offer versatile camera systems, but with different configurations and capabilities.

• Rear Camera System: The Galaxy S21 Ultra 5G features a quad-camera setup with a 108 MP main sensor, a 12 MP ultrawide, and two 10 MP telephoto lenses offering 3x and 10x optical zoom. The Galaxy S23 Plus has a triple-camera system with a 50 MP main sensor, a 12 MP ultrawide, and a 10 MP telephoto lens with 3x optical zoom.
• Photography Performance: The S21 Ultra 5G's 108 MP main sensor excels in capturing detailed images, and its dual telephoto lenses provide exceptional zoom flexibility, particularly the 10x optical zoom for distant subjects. The S23 Plus, with its 50 MP main sensor, delivers excellent everyday photos with improved image processing, often resulting in vibrant and well-exposed shots. In low-light conditions, both perform well, but the S23 Plus benefits from newer software optimizations for clearer night shots.
• Video Recording: Both devices are capable of recording high-quality video, including 8K resolution. The S23 Plus offers enhanced video stabilization and improved low-light video performance due to its newer processor and sensor optimizations.
• Front Camera: The S21 Ultra 5G features a high-resolution 40 MP front camera. The S23 Plus comes with a 12 MP front camera, which, despite the lower megapixel count, offers improved autofocus and better low-light performance for selfies and video calls.
