Galaxy S23 • Unlocked vs Galaxy S24 • Unlocked

The Samsung Galaxy S23, released in February 2023, and the Samsung Galaxy S24, launched in January 2024, represent consecutive generations of Samsung's compact flagship smartphones. While they share a similar design philosophy and core functionalities, the Galaxy S24 introduces notable advancements in software longevity, display brightness, and subtle performance enhancements. Both devices operate on the Android platform with Samsung's One UI, offering a consistent user experience.

The practical lifespan of a smartphone is significantly influenced by its software support and physical resilience. Both the Galaxy S23 and S24 offer robust build quality, but their long-term software commitments differ.

• Software Support: The Galaxy S23 is guaranteed to receive four years of major Android operating system updates and five years of security updates. In contrast, the Galaxy S24 sets a new standard with a commitment to seven years of both operating system and security updates, providing a considerably longer period of official support.
• Physical Durability: Both models feature an IP68 rating for dust and water resistance, indicating protection against immersion. The Galaxy S23 utilizes Gorilla Glass Victus+ for screen protection and an Armor Aluminum frame. The Galaxy S24 upgrades to Gorilla Glass Armor and a stronger version of Armor Aluminum, suggesting enhanced resilience. However, some independent drop tests have indicated that the Galaxy S24, despite its newer materials, may be more susceptible to damage in certain drop scenarios compared to its predecessor.
• Repairability: While specific repairability scores can vary, both devices are constructed with modern smartphone design principles that can make certain repairs complex. The availability of parts and service expertise generally remains consistent for recent Samsung flagships.

The performance of a smartphone dictates its responsiveness and capability to handle various applications and tasks. Both the Galaxy S23 and S24 deliver strong performance, though the newer model offers generational improvements.

• Processing Power: The Galaxy S23 is equipped with a processor that provides efficient and capable performance for daily tasks, demanding applications, and mobile gaming. The Galaxy S24 features an updated processor, which, depending on the region, can offer smoother operation, faster app loading times, and improved thermal management during extended use. This results in a more fluid experience, particularly with intensive multitasking or graphically rich games.
• Storage and Responsiveness: Both devices offer various internal storage options, typically starting at 128GB, with higher capacities like 256GB and 512GB also available. The Galaxy S24 utilizes faster UFS 4.0 storage for its 256GB and 512GB configurations, which can contribute to quicker data access and app launch times compared to the UFS 3.1 found in the 128GB Galaxy S23. Both models generally come with 8GB of RAM, which is sufficient for managing multiple applications simultaneously.
• Battery Behavior: The Galaxy S23 houses a 3,900mAh battery, while the Galaxy S24 has a slightly larger 4,000mAh battery. In practical use, both phones offer comparable screen-on times, often lasting a full day for moderate users. The Galaxy S24's slightly larger battery and more efficient display technology can contribute to marginally extended usage for some users.

The display is a primary interface for smartphone interaction, and both the Galaxy S23 and S24 offer high-quality viewing experiences with some key distinctions.

• Display Technology and Size: Both devices feature a Dynamic AMOLED 2X display with a Full HD+ resolution, providing clear and vibrant visuals. The Galaxy S23 has a 6.1-inch screen, while the Galaxy S24 offers a slightly larger 6.2-inch display. This minor size increase on the S24 results in a slightly more expansive viewing area without significantly altering the phone's overall dimensions.
• Brightness and Visibility: The Galaxy S23 achieves a peak brightness of 1,750 nits. The Galaxy S24 significantly increases this to a peak brightness of 2,600 nits. This higher brightness on the S24 improves outdoor visibility, making content easier to view under direct sunlight.
• Refresh Rate and Efficiency: Both phones feature an adaptive refresh rate that can go up to 120Hz for smooth scrolling and animations. The Galaxy S23's adaptive refresh rate ranges from 48Hz to 120Hz. The Galaxy S24 enhances this by offering a wider adaptive range, capable of scaling down to 1Hz. This wider range allows the S24 to be more power-efficient when displaying static content, as it can reduce the refresh rate to conserve battery.

The camera systems on the Galaxy S23 and S24 are designed to capture high-quality photos and videos, sharing much of the same hardware while offering subtle differences in image processing.

• Camera Hardware: Both the Galaxy S23 and S24 feature a triple-camera setup on the rear, consisting of a 50-megapixel main sensor, a 12-megapixel ultrawide lens, and a 10-megapixel telephoto lens with 3x optical zoom. The front-facing camera on both models is a 12-megapixel sensor. This identical hardware means both phones are capable of capturing detailed images across various focal lengths.
• Image Processing and Quality: While the hardware is similar, the Galaxy S24 benefits from updated image processing algorithms. Users often report that the S24 produces more natural-looking colors, improved exposure, and better dynamic range compared to the S23, which sometimes tends towards oversaturation. In low-light conditions, the S24 can resolve more detail and produce less noisy images.
• Video and Audio Experience: Both devices are capable of recording high-quality video, including 4K at 60fps and 8K at 30fps, with effective stabilization. The overall video recording experience is largely consistent between the two. For audio, both phones include stereo speakers, providing a capable media consumption experience and clear audio for calls.
