Galaxy S24 vs Galaxy S25 Ultra

The Samsung Galaxy S24, released in January 2024, and the Samsung Galaxy S25 Ultra, launched in February 2025, represent distinct offerings within Samsung's flagship smartphone lineup. While both operate on the Android platform with Samsung's One UI, the S25 Ultra, as a later and more premium model, introduces advancements in display technology, camera capabilities, and overall processing power. This comparison will explore the practical differences between these two devices to help users determine which aligns best with their needs.

When considering the longevity of a smartphone, both the Galaxy S24 and the Galaxy S25 Ultra offer substantial software support and robust build quality.

• Software Support: Both devices benefit from Samsung's commitment to seven years of operating system and security updates. The Galaxy S24, released in early 2024, is supported through 2031, while the Galaxy S25 Ultra, released in early 2025, extends this support through 2032, offering an additional year of updates.
• Physical Durability: The Galaxy S24 features an Armor Aluminum frame and Gorilla Glass Victus 2 for screen protection, providing a good level of resistance against drops and scratches. The Galaxy S25 Ultra elevates this with a titanium frame and Gorilla Glass Armor 2, which offers enhanced durability and improved scratch resistance, along with anti-reflective properties. Both models carry an IP68 rating for dust and water resistance.
• Expected Lifespan: Given their extended software support and durable construction, both phones are designed for a practical lifespan of several years. The S25 Ultra's newer release date and advanced protective materials may offer a slight edge in long-term physical resilience and software relevance.

Performance is a key differentiator, with the Galaxy S25 Ultra featuring a newer generation of internal components designed for more demanding tasks compared to the Galaxy S24.

• Processing Power: The Galaxy S24 is equipped with a powerful current-generation processor (Snapdragon 8 Gen 3 or Exynos 2400 depending on region) that handles everyday applications, multitasking, and gaming smoothly. The Galaxy S25 Ultra, however, integrates a next-generation processor (Snapdragon 8 Elite, equivalent to Snapdragon 8 Gen 4), which provides a significant boost in CPU, GPU, and AI performance, making it exceptionally responsive for intensive applications and future-proofed for emerging technologies.
• Multitasking and Storage: The Galaxy S24 typically comes with 8GB of RAM, sufficient for most multitasking needs, and offers storage options up to 512GB, utilizing UFS 4.0 for faster data access in higher capacities. The Galaxy S25 Ultra generally starts with 12GB of RAM, with some regions offering 16GB, providing more headroom for heavy multitasking and advanced AI features. Its storage options also extend up to 1TB, with UFS 4.0, potentially with improved speeds.
• Battery Behavior: The Galaxy S24 features a 4000 mAh battery, which users report provides good battery life for a full day of moderate use. The Galaxy S25 Ultra houses a larger 5000 mAh battery, offering extended usage times, though some users have noted that the capacity remains consistent with previous Ultra models rather than seeing an increase. Both support fast wired and wireless charging.

The visual experience on both devices is vibrant, but the Galaxy S25 Ultra offers a larger display with higher resolution and advanced features.

• Display Technology and Size: The Galaxy S24 features a 6.2-inch Dynamic AMOLED 2X display with a Full HD+ resolution, offering clear visuals and vibrant colors. The Galaxy S25 Ultra boasts a larger 6.9-inch Dynamic LTPO AMOLED 2X display with a Quad HD+ resolution, providing a more expansive and detailed viewing area.
• Brightness and Smoothness: Both phones achieve a peak brightness of up to 2600 nits, ensuring good visibility even in bright outdoor conditions. They also feature an adaptive 120Hz refresh rate, contributing to smooth scrolling and responsive interactions. The S25 Ultra includes ProScaler AI upscaling technology to enhance lower-resolution content on its high-resolution display.
• Viewing Experience: While the S24 provides an excellent compact display, the S25 Ultra's larger, higher-resolution screen is better suited for immersive media consumption and detailed work. Some reports indicate the S25 Ultra uses similar display panel materials to the S24 series and an 8-bit panel, which some users might find less advanced compared to other flagships.

Both smartphones offer capable camera systems, but the Galaxy S25 Ultra presents a more advanced and versatile setup, particularly in its ultrawide and telephoto capabilities.

• Rear Camera System: The Galaxy S24 features a triple-camera setup with a 50MP main sensor, a 12MP ultrawide, and a 10MP telephoto lens with 3x optical zoom. This system delivers good image quality in various conditions, though its low-light performance and telephoto results are noted as competent but not always class-leading. The Galaxy S25 Ultra comes with a quad-camera array, including a 200MP main sensor, a significantly upgraded 50MP ultrawide sensor, a 50MP telephoto with 5x optical zoom, and a 10MP telephoto with 3x optical zoom. The enhanced ultrawide sensor is a notable improvement over its predecessor.
• Photography and Video Features: Both devices support 8K video recording. The S24 offers versatile shooting modes and AI-powered editing tools. The S25 Ultra's ProVisual Engine and advanced AI enhancements contribute to improved detail reconstruction and object-aware processing, aiming for superior image quality across its multiple lenses.
• Front Camera and Audio: Both phones include a 12MP front-facing camera for selfies and video calls. For audio, both feature stereo speakers tuned by AKG, providing a rich media consumption experience, and offer good microphone quality for calls and recordings.
