Galaxy S25 • Unlocked vs Galaxy Z Flip5 • Unlocked

The Samsung Galaxy S25, released in early 2025, represents the latest iteration of Samsung's traditional flagship smartphone line, offering a conventional form factor with cutting-edge technology. In contrast, the Samsung Galaxy Z Flip5, launched in mid-2023, stands out with its unique clamshell foldable design. The primary differentiators between these two Android devices lie in their form factor, the generation of their internal components, and their respective camera systems, catering to distinct user preferences.

The longevity of a smartphone is influenced by its release timeline, software support, and physical resilience. The Galaxy S25 and Galaxy Z Flip5 offer different profiles in these areas.

• Release Timeline: The Galaxy S25 was released in February 2025, making it a newer device compared to the Galaxy Z Flip5, which launched in August 2023. This difference in age means the S25 benefits from more recent hardware and a longer period of future software support.
• Software Longevity: The Galaxy S25 ships with Android 15 and is promised 7 years of major OS and security updates, extending its support until approximately 2032. The Galaxy Z Flip5, initially running Android 13, is committed to 4 generations of OS upgrades (up to Android 17) and 5 years of security updates, with support expected through 2028. Users prioritizing the longest possible software support will find the S25 offers an extended timeline.
• Physical Durability: The Galaxy S25 features Gorilla Glass Victus 2 on both its front and back, encased in an aluminum frame, and boasts an IP68 rating for dust and water resistance, allowing submersion in up to 1.5 meters of water for 30 minutes. The Galaxy Z Flip5 also uses Gorilla Glass Victus 2 for its cover screen and back panel, with an Armor Aluminum frame, and carries an IPX8 water resistance rating, meaning it can withstand submersion but does not have official dust resistance. Its redesigned hinge allows it to fold completely flat, which contributes to its overall structural integrity when closed.

Performance is a key consideration for daily usage, encompassing processing power, multitasking capabilities, and battery endurance. The two devices offer distinct experiences based on their internal hardware.

• Processing Power: The Galaxy S25 is equipped with a current-generation processor, manufactured on a 3nm process, which provides substantial improvements in speed and efficiency for demanding applications and complex tasks. The Galaxy Z Flip5 utilizes a previous-generation processor, built on a 4nm process, which still delivers smooth performance for everyday use and most applications, but may show limitations in highly intensive scenarios compared to the S25.
• Multitasking and Storage: All Galaxy S25 models come with 12GB of RAM, facilitating seamless multitasking and efficient handling of numerous open applications. The Galaxy Z Flip5 features 8GB of RAM, which is sufficient for typical smartphone usage, though power users might notice a difference when juggling many demanding apps. Both devices offer ample internal storage options, with the S25 available in 128GB, 256GB, and 512GB, and the Z Flip5 in 256GB and 512GB configurations.
• Battery Behavior: The Galaxy S25 houses a 4000 mAh battery, which, combined with its efficient processor and display technology, is designed to provide reliable power throughout a full day of varied use. The Galaxy Z Flip5 has a 3700 mAh battery. While it shows improved endurance over its predecessor, heavy users might find themselves needing to recharge more frequently, with some reports indicating around 5 hours of screen-on time on Wi-Fi and 4 hours on 5G.

The visual experience is a significant aspect of smartphone use, and both devices offer high-quality displays with distinct characteristics.

• Display Technology and Clarity: The Galaxy S25 features a 6.2-inch Dynamic LTPO AMOLED 2X display with a resolution of 2340 x 1080 pixels, providing sharp and vibrant visuals. The Galaxy Z Flip5's main display is a 6.7-inch Foldable Dynamic AMOLED 2X with a resolution of 1080 x 2640 pixels, offering a larger viewing area when unfolded. Both utilize AMOLED technology for deep blacks and excellent contrast.
• Brightness and Refresh Rate: The S25's display can reach a peak brightness of 2600 nits, ensuring good visibility even in bright outdoor conditions. The Z Flip5's main screen has a peak brightness of around 1200 nits (some sources indicate 1750 nits), which is still bright for most environments. Both phones feature a 120Hz adaptive refresh rate, contributing to smooth scrolling and fluid animations.
• Unique Display Features: A key differentiator for the Galaxy Z Flip5 is its 3.4-inch Super AMOLED cover screen, which offers a resolution of 720 x 748 pixels. This external display allows users to interact with widgets, view notifications, and even take selfies without unfolding the phone. The S25, with its traditional form factor, offers a continuous, uninterrupted display experience.

Camera capabilities are a significant factor for many users, and both the Galaxy S25 and Galaxy Z Flip5 offer robust systems, though with different strengths.

• Rear Camera Systems: The Galaxy S25 features a versatile triple-camera setup on the rear, including a 50MP wide-angle main sensor with optical image stabilization (OIS), a 12MP ultra-wide lens with a 120-degree field of view, and a 10MP telephoto lens offering 3x optical zoom and OIS. This configuration provides flexibility for various photographic situations, from expansive landscapes to detailed close-ups. The Galaxy Z Flip5 has a dual-camera system on the rear, comprising a 12MP wide-angle main sensor with OIS and a 12MP ultra-wide lens with a 123-degree field of view. While capable for everyday photography, it lacks a dedicated telephoto lens.
• Low-Light and Video Performance: Both devices are designed to perform well in various lighting conditions, with the S25 benefiting from its newer sensor technology and advanced image processing. The S25 can record video at up to 8K resolution at 30 frames per second, offering high-detail video capture. The Z Flip5 records video at up to 4K resolution at 30/60 frames per second.
• Unique Camera Features: The Galaxy Z Flip5 leverages its foldable design for unique camera functionalities, such as Flex Mode, which allows the phone to be partially folded to act as its own tripod for hands-free photos and video calls. The large cover screen also enables high-quality selfies using the more capable rear cameras. The S25, with its traditional design, offers a more straightforward point-and-shoot experience with its advanced hardware.
