Galaxy S21 FE 5G vs Galaxy S23 Ultra

The Samsung Galaxy S21 FE 5G, released in January 2022, and the Samsung Galaxy S23 Ultra, launched in February 2023, represent different segments and generations within Samsung's smartphone lineup. While both operate on the Android platform, the S23 Ultra offers a more advanced feature set and higher-end specifications compared to the S21 FE 5G, which is designed to deliver a flagship-like experience at a more accessible point. Key differentiators include processor power, camera capabilities, and overall display technology.

When considering the longevity of these devices, several factors come into play, including their release timelines, software support, and physical resilience.

• Release Timeline: The Galaxy S21 FE 5G was released in January 2022, making it approximately a year older than the Galaxy S23 Ultra, which launched in February 2023. This age difference directly impacts the duration of software support each device is expected to receive.
• Software Longevity: Samsung typically provides several years of Android operating system updates and security patches for its devices. The S23 Ultra, being newer, is anticipated to receive software updates for a longer period, generally offering four years of Android updates and five years of security patches from its release date. The S21 FE 5G, having launched earlier, will have a shorter remaining support window, though it has received updates up to Android 14.
• Physical Durability: Both models feature an IP68 rating for dust and water resistance, indicating protection against immersion in up to 1.5 meters of fresh water for 30 minutes. The S21 FE 5G uses Corning Gorilla Glass Victus for screen protection, while the S23 Ultra incorporates the newer Corning Gorilla Glass Victus 2 on both its front and back, along with an Armor Aluminum frame, offering enhanced resistance to drops and scratches. The S23 Ultra has also shown improvements in repairability, with easier battery replacement noted in teardowns.

The performance of a smartphone is largely determined by its internal components, influencing how smoothly applications run, how quickly tasks are completed, and the overall responsiveness of the user interface.

• Processing Power: The Galaxy S21 FE 5G is equipped with a processor capable of handling everyday tasks and moderate gaming efficiently. The Galaxy S23 Ultra, however, features a more advanced, current-generation processor specifically optimized for Galaxy devices, which delivers significantly faster CPU and GPU speeds. This results in a more fluid experience for demanding applications, intensive multitasking, and graphics-heavy gaming.
• System Responsiveness and Multitasking: The S23 Ultra's more powerful processing unit and often higher RAM configurations (up to 12GB compared to the S21 FE 5G's up to 8GB) contribute to superior overall system responsiveness and smoother transitions between multiple open applications. Users engaging in heavy multitasking or running complex software will likely notice a more immediate and consistent performance on the S23 Ultra.
• Storage and Efficiency: Both devices offer various internal storage options, though neither supports expandable storage via microSD cards. The S23 Ultra, particularly in its higher storage variants, often utilizes newer, faster storage technologies, which can translate to quicker app loading times and file transfers.

The visual experience on a smartphone is primarily defined by its display, encompassing factors like technology, resolution, brightness, and refresh rate.

• Display Technology and Clarity: Both the Galaxy S21 FE 5G and the Galaxy S23 Ultra feature Dynamic AMOLED 2X displays, known for their vibrant colors and deep blacks. However, the S23 Ultra offers a larger 6.8-inch display with a higher QHD+ resolution (3088x1440 pixels) and a pixel density of 500 ppi, providing a sharper and more detailed image compared to the S21 FE 5G's 6.4-inch FHD+ display (1080x2400 pixels) with 401 ppi.
• Brightness and Outdoor Visibility: The S23 Ultra boasts a significantly higher peak brightness of 1750 nits, which enhances visibility in bright outdoor conditions and improves HDR content viewing. The S21 FE 5G has a peak brightness of 1200 nits, which is still good but less intense than the S23 Ultra.
• Refresh Rate and Smoothness: Both models feature a 120Hz refresh rate, contributing to smoother scrolling and more fluid animations. The S23 Ultra further enhances this with an adaptive refresh rate that can scale from 1Hz to 120Hz, optimizing power consumption by adjusting to the content being displayed.

The camera systems on both devices offer distinct capabilities for capturing photos and videos, catering to different levels of photographic ambition.

• Rear Camera System: The Galaxy S21 FE 5G features a versatile triple-camera setup with a 12MP wide lens, a 12MP ultrawide lens, and an 8MP telephoto lens with 3x optical zoom. The Galaxy S23 Ultra elevates this significantly with a quad-camera system, including a high-resolution 200MP wide sensor, a 12MP ultrawide, a 10MP telephoto with 3x optical zoom, and another 10MP telephoto with an impressive 10x optical zoom. This allows the S23 Ultra to capture much finer detail and offer greater zoom flexibility.
• Photography Performance: The S23 Ultra's larger main sensor and advanced image processing contribute to superior low-light performance, capturing more detailed and vibrant photos in challenging conditions. While the S21 FE 5G performs well in good lighting, the S23 Ultra generally provides more consistent and higher-quality results across various scenarios, including astrophotography capabilities.
• Video Recording and Front Camera: Both phones support 4K video recording at 30/60fps. The S23 Ultra extends its video capabilities to 8K recording at 24/30fps, offering higher resolution video capture. For selfies, the S21 FE 5G has a 32MP front camera, while the S23 Ultra features a 12MP front camera, both capable of capturing detailed self-portraits and video calls.
