When considering the long-term usability of a smartphone, factors like software support, physical resilience, and ease of repair are important. The Galaxy S23 FE and S24 Ultra offer different propositions in these areas.

• Software Longevity: The Galaxy S24 Ultra, being a newer flagship, is promised an extended software support period of seven years, including major Android updates and security patches, ensuring it remains current for a significantly longer duration. The Galaxy S23 FE, while also receiving substantial updates, will likely have a shorter support window, typically around four to five years from its release. [32]
• Physical Durability: The Galaxy S24 Ultra features a titanium frame and Corning Gorilla Armor on its display, offering enhanced resistance to scratches and drops. [5, 9, 20, 21, 29, 32] The Galaxy S23 FE utilizes an aluminum frame and Gorilla Glass 5 for screen protection, providing solid, but less advanced, physical resilience. [16, 42, 46] Both devices carry an IP68 rating for dust and water resistance. [10, 32, 46]
• Repairability: The Galaxy S24 Ultra has demonstrated a high repairability score in teardowns, with components like the battery designed for easier replacement, contributing to a potentially longer practical lifespan through maintenance. [4, 14, 33] Information on the S23 FE's specific repairability score is less prominent, but Samsung has generally been improving repair access across its range.

The performance of a smartphone is crucial for daily operations, from navigating apps to handling demanding tasks. The Galaxy S23 FE and S24 Ultra are equipped with different internal components that translate to varying real-world experiences.

• Processing Power: The Galaxy S24 Ultra is powered by a current-generation processor, enabling it to handle intensive applications, complex multitasking, and advanced mobile gaming with exceptional smoothness and efficiency. [9, 13, 20, 23] The Galaxy S23 FE features a previous-generation flagship processor, which still delivers robust performance for everyday use and most applications, though it may show limitations with the most graphically demanding games or sustained heavy workloads. [7, 31, 37, 44]
• Multitasking and Storage: The S24 Ultra typically comes with 12GB of RAM and offers storage options up to 1TB, providing ample space and memory for extensive app usage and large files. [9, 13, 20, 29] The S23 FE is equipped with 8GB of RAM and storage options up to 256GB, which is sufficient for most users but offers less headroom for power users or those with extensive media libraries. [7, 10, 15, 31]
• Battery Behavior: The Galaxy S24 Ultra, with its 5000mAh battery and efficient processor, consistently delivers excellent battery life, often lasting more than a full day even with heavy usage. [17, 22, 26, 30, 34] Users report significant screen-on time. [11, 22] The S23 FE, with a 4500mAh battery, generally provides a full day of typical use, though heavy users might find themselves needing to recharge before the day ends. [1, 3, 8, 24, 28]

The display is a primary interface for any smartphone, and both the Galaxy S23 FE and S24 Ultra offer vibrant viewing experiences, albeit with distinct differences in technology and capabilities.

• Display Technology and Clarity: Both devices feature Dynamic AMOLED 2X displays, known for deep blacks and vibrant colors. The S24 Ultra boasts a larger 6.8-inch QHD+ display (3120x1440 pixels), offering superior sharpness and detail compared to the S23 FE's 6.4-inch FHD+ display (2340x1080 pixels). [2, 5, 10, 20, 29, 32, 37, 40, 43, 44]
• Brightness and Refresh Rate: The S24 Ultra achieves a peak brightness of 2600 nits, making it exceptionally readable in bright outdoor conditions, and features an adaptive refresh rate from 1Hz to 120Hz for smooth scrolling and power efficiency. [5, 20, 21, 29, 32, 40] The S23 FE offers a peak brightness of 1450 nits (some sources say 1500 nits) and a 120Hz refresh rate, which is still bright and fluid for most environments but less dynamic than the S24 Ultra. [2, 37, 42, 43, 44]
• Viewing Experience: The S24 Ultra features a flat display with an anti-reflective coating, which can enhance the viewing experience by reducing glare. [20, 39, 40] The S23 FE has slightly thicker bezels, which might impact the immersive feel compared to the S24 Ultra's more expansive screen-to-body ratio. [42, 44, 46]

Camera systems are a significant differentiator, and both Samsung devices offer versatile setups, with the S24 Ultra providing a more advanced and feature-rich photography experience.

• Rear Camera System: The Galaxy S24 Ultra features a quad-camera setup, including a 200MP main sensor, a 12MP ultrawide, a 10MP 3x telephoto, and a 50MP 5x telephoto lens, offering extensive zoom capabilities and detail. [9, 12, 13, 18, 20, 27, 29, 32, 35] The S23 FE comes with a triple-camera system: a 50MP main sensor with optical image stabilization, a 12MP ultrawide, and an 8MP 3x optical telephoto lens. [1, 3, 6, 7, 10, 16, 37, 45, 46]
• Photography Performance: The S24 Ultra excels in various lighting conditions, with its larger sensors and advanced processing contributing to excellent low-light performance and detailed images across its zoom range. [12, 18, 27] The S23 FE delivers good quality photos, especially in well-lit conditions, and its 3x optical zoom is a notable feature for its category. [1, 3, 6, 16, 45] However, some users note that S23 FE colors can be oversaturated. [1]
• Video Recording and Front Camera: Both phones can record video up to 8K resolution, with the S24 Ultra supporting 8K at 30fps and the S23 FE at 24fps.
