Galaxy A04S Vs Galaxy S25 Ultra

The Samsung Galaxy A04S, released in September 2022, and the Samsung Galaxy S25 Ultra, launched in February 2025, represent distinct segments within Samsung's smartphone offerings. While the A04S focuses on essential smartphone functionalities, the S25 Ultra is engineered for advanced performance and premium features. These devices differ significantly in their processing power, display technology, and camera capabilities, catering to varied user needs and expectations.

The practical lifespan of a smartphone is influenced by its release timeline, software support, and physical durability.

• Release Timeline and Software Support: The Galaxy A04S, released in late 2022, launched with Android 12 and has received updates up to Android 14, which is its final major OS update. In contrast, the Galaxy S25 Ultra, released in early 2025, ships with Android 15 and is guaranteed to receive seven years of major OS upgrades and security updates. This extended support means the S25 Ultra will remain current with software features and security patches for a significantly longer period.
• Physical Durability and Repairability: The Galaxy A04S features a plastic construction, which offers a degree of resilience to everyday bumps but lacks official water and dust resistance. The Galaxy S25 Ultra, however, incorporates premium materials like Corning Gorilla Armor 2 glass on both the front and back, along with a titanium frame, providing enhanced protection against drops and scratches. It also boasts an IP68 rating for dust and water resistance. For repairability, the S25 Ultra received an iFixit score of 5 out of 10, indicating improved ease of repair compared to many previous Samsung flagships, particularly concerning battery replacement.

Performance differences between these two models are substantial, reflecting their respective market positions and design philosophies.

• Processing Power and Responsiveness: The Galaxy A04S is equipped with an entry-level octa-core processor, suitable for basic daily tasks like browsing, social media, and light applications. Users may experience occasional delays or sluggishness when multitasking or running more demanding apps. The Galaxy S25 Ultra, powered by a current-generation, high-performance processor, delivers smooth and rapid execution across all tasks, from intensive gaming and video editing to seamless multitasking. Its architecture is designed to handle complex computations and advanced AI features efficiently.
• Memory and Storage: The A04S typically comes with 3GB or 4GB of RAM and 32GB to 128GB of internal storage, which can be expanded using a microSD card. This configuration is adequate for users with moderate storage needs and limited simultaneous app usage. The S25 Ultra offers a more robust setup with 12GB of RAM as standard in most regions, and up to 1TB of fast internal storage, without microSD expansion. This ample memory and storage capacity support extensive app libraries, large media files, and fluid transitions between numerous open applications.
• Battery Performance: Both devices feature a 5000 mAh battery. The Galaxy A04S, with its less demanding hardware and lower-resolution display, can comfortably last over a full day with moderate usage. The S25 Ultra, despite its powerful components and high-resolution display, is optimized for efficient power consumption, with many users reporting a full day of use, even with demanding tasks. It also supports faster 45W wired charging and Qi2 wireless charging.

The visual experience offered by these two smartphones differs significantly due to their display technologies and specifications.

• Display Technology and Resolution: The Galaxy A04S features a 6.5-inch PLS LCD display with an HD+ resolution (720 x 1600 pixels). This provides clear visuals for everyday content, though fine details might appear less sharp compared to higher-resolution screens. The Galaxy S25 Ultra boasts a larger 6.9-inch Dynamic LTPO AMOLED 2X display with a QHD+ resolution (1440 x 3120 pixels), offering exceptional clarity, deep blacks, and vibrant colors.
• Brightness and Refresh Rate: The A04S has a typical brightness of around 380 nits and a 90Hz refresh rate, which provides smoother scrolling than a standard 60Hz display. The S25 Ultra reaches a peak brightness of 2600 nits, ensuring excellent visibility even in bright outdoor conditions, and features an adaptive 120Hz refresh rate for incredibly fluid animations and responsiveness. The S25 Ultra also includes an anti-reflective coating for improved viewing in various lighting environments.

Camera capabilities are a primary differentiator, with each device catering to different photography expectations.

• Rear Camera System: The Galaxy A04S includes a triple rear camera setup with a 50MP main sensor, complemented by 2MP macro and 2MP depth sensors. It performs adequately in well-lit conditions, capturing decent detail and color, but struggles with low-light environments and dynamic range. The Galaxy S25 Ultra features a sophisticated quad-camera system: a 200MP main sensor with optical image stabilization (OIS), a 50MP ultrawide lens, a 10MP telephoto lens with 3x optical zoom and OIS, and a 50MP periscope telephoto lens with 5x optical zoom and OIS. This array delivers exceptional detail, dynamic range, and versatility across various lighting conditions and zoom levels.
• Front Camera and Video Recording: The A04S has a 5MP front camera and can record video at 1080p at 30 frames per second. The S25 Ultra features a 12MP front camera and supports advanced video recording up to 8K at 30 frames per second and 4K at 120 frames per second, with enhanced stabilization and HDR capabilities. Both devices offer satisfactory selfie quality in good lighting, but the S25 Ultra provides more detail and better performance in challenging conditions.
