Galaxy A35 vs Galaxy S25 Ultra

The Samsung Galaxy A35 and the Samsung Galaxy S25 Ultra are two distinct smartphones from Samsung's 2024 and 2025 lineups, respectively. While both run on the Android operating system with Samsung's One UI, they cater to different user needs through their varied specifications and feature sets. The Galaxy A35, released in March 2024, focuses on delivering a balanced experience for everyday use, whereas the Galaxy S25 Ultra, launched in February 2025, represents Samsung's top-tier offering with advanced capabilities and premium features.

The expected lifespan of a smartphone is significantly influenced by its software support and physical durability. These two Samsung models offer different commitments in this regard.

• Software Longevity: The Galaxy A35, released in March 2024, is promised four generations of Android OS upgrades and five years of security updates, extending its software support until approximately 2029. In contrast, the Galaxy S25 Ultra, launched in February 2025, benefits from Samsung's extended policy, receiving seven generations of OS upgrades and seven years of security updates, ensuring support until around 2032. This difference means the S25 Ultra will remain current with the latest Android features and security patches for a significantly longer period.
• Physical Durability: The Galaxy A35 features a Gorilla Glass Victus+ front and an IP67 rating for dust and water resistance, offering protection against splashes and submersion in shallow water. The Galaxy S25 Ultra elevates this with Gorilla Glass Armor 2 on its display and an IP68 rating, providing enhanced resistance to dust and water, making it more resilient in various environments.
• Repairability: While specific repairability scores can vary by region and independent assessments, both devices are designed with modern smartphone construction. Flagship devices like the S25 Ultra often feature more complex internal designs due to advanced components, potentially impacting the ease of repair compared to more straightforward mid-range models like the A35.

Performance is a key differentiator, with the Galaxy S25 Ultra designed for demanding tasks and the Galaxy A35 for reliable daily usage.

• Processing Power: The Galaxy A35 handles everyday applications and multitasking smoothly, providing a responsive experience for general use. However, users might notice occasional delays when launching very demanding applications or during extended, intensive gaming sessions. The Galaxy S25 Ultra, equipped with a current-generation flagship processor, delivers exceptionally fast and fluid performance across all tasks, from heavy multitasking and graphic-intensive gaming to advanced AI features, maintaining smooth operation even under sustained load.
• Multitasking and Storage: The Galaxy A35 typically comes with 6GB or 8GB of RAM and offers expandable storage via a microSD card, which is beneficial for users who need to store a large volume of media or documents. The Galaxy S25 Ultra, with 12GB or 16GB of RAM, provides substantial headroom for running numerous applications simultaneously without slowdowns, though it does not offer expandable storage.
• Battery Behavior: Both devices feature a 5000mAh battery capacity. The Galaxy A35 is noted for its strong battery life, often lasting up to two days with moderate use or around seven hours of screen-on time with normal usage. The Galaxy S25 Ultra also offers robust battery performance, typically lasting more than a full day even with heavy use, providing around six to seven hours of screen-on time.

The visual experience on both devices is vibrant, though the S25 Ultra offers a more advanced display technology.

• Display Technology and Clarity: The Galaxy A35 features a 6.6-inch Super AMOLED display with Full HD+ resolution, offering deep blacks and vibrant colors suitable for media consumption and daily tasks. The Galaxy S25 Ultra boasts a larger 6.9-inch Dynamic LTPO AMOLED 2X display with a sharper QHD+ resolution, providing superior detail and clarity, making it ideal for high-resolution content and productivity.
• Brightness and Refresh Rate: Both phones feature a 120Hz refresh rate for smooth scrolling and responsive interactions. The Galaxy A35's display offers sufficient brightness for outdoor use, though some users report colors can appear somewhat washed out in direct sunlight. The Galaxy S25 Ultra stands out with a peak brightness of up to 2600 nits and an anti-reflective coating, ensuring excellent visibility and color accuracy even in bright outdoor conditions.
• Viewing Experience: The A35 provides a captivating viewing experience for everyday use, with crisp colors. The S25 Ultra's larger, higher-resolution display with adaptive refresh rate technology and enhanced brightness makes it particularly well-suited for immersive gaming, professional content creation, and extended media viewing.

Both smartphones offer capable camera systems, but the S25 Ultra provides a more versatile and advanced photography experience.

• Rear Camera System: The Galaxy A35 features a triple-camera setup with a 50MP main sensor (with optical image stabilization), an 8MP ultrawide, and a 5MP macro lens. It captures good daylight photos with natural tones, but low-light performance can show blur and noise. The Galaxy S25 Ultra comes with a quad-camera system, including a 200MP main sensor, a 50MP ultrawide, a 50MP telephoto with 5x optical zoom, and a 10MP telephoto with 3x optical zoom. This setup delivers exceptional detail, dynamic range, and versatile zoom capabilities, performing well in various lighting conditions, though motion in low light can be a challenge.
• Video Recording and Features: Both devices support 4K video recording at 30 frames per second on their main and front cameras. The S25 Ultra further enhances video capabilities with features like LOG video capture, which is beneficial for creators seeking more control in post-production.
• Front Camera and Audio: The Galaxy A35 has a 13MP front camera, capable of capturing natural skin tones. The Galaxy S25 Ultra features a 12MP front camera. Both phones include stereo speakers, with the S25 Ultra offering a richer audio experience with Dolby Atmos support.
