Galaxy S9 • Unlocked vs iPhone SE (2020) • Unlocked

The Samsung Galaxy S9, released in March 2018, and the iPhone SE 2020, launched in April 2020, represent distinct approaches to smartphone design and functionality from their respective manufacturers. While the Galaxy S9 offered a premium Android experience with a focus on display technology and multimedia, the iPhone SE 2020 brought powerful internal components within a classic Apple design. These devices cater to different user preferences, primarily differing in their operating systems, design philosophies, and long-term software support.

The practical lifespan of a smartphone is significantly influenced by its release timeline and the duration of software support it receives.

• Release Timeline: The Samsung Galaxy S9 was released in March 2018, making it two years older than the iPhone SE 2020, which launched in April 2020. This age difference directly impacts their remaining support cycles.
• Software Longevity: The Galaxy S9 officially concluded its major Android updates with Android 10, and its security updates ended in April 2022, meaning it no longer receives official software enhancements or security patches. In contrast, the iPhone SE 2020, which launched with iOS 13.4, has continued to receive updates, including iOS 17, and is expected to support future iOS versions for several more years, offering a longer period of official software and security support.
• Durability Features: Both devices feature glass front and back panels with aluminum frames. The Galaxy S9 has an IP68 rating for dust and water resistance, allowing submersion up to 1.5 meters for 30 minutes. The iPhone SE 2020 has an IP67 rating, protecting against submersion up to 1 meter for 30 minutes. While both offer good protection against everyday spills, the Galaxy S9 has a slightly higher water resistance rating.

Evaluating the performance of these devices involves looking at their processing capabilities, memory, and how they manage power for daily use.

• Processing Power: The iPhone SE 2020 is equipped with a more recent-generation processor, which allows it to handle demanding applications, complex games, and intensive multitasking with greater fluidity and responsiveness. The Galaxy S9, while capable for general use, features an older processor that may exhibit slower performance with newer, more resource-intensive applications.
• Multitasking and Storage: The Galaxy S9 typically comes with 4GB of RAM, while the iPhone SE 2020 has 3GB of RAM. Despite the difference in raw RAM numbers, the iPhone's optimized operating system often allows it to manage applications efficiently. Both devices offer similar internal storage options, ranging from 64GB to 256GB. The Galaxy S9 also includes a microSD card slot for expandable storage, a feature not present on the iPhone SE 2020.
• Battery Behavior: The Galaxy S9 houses a 3000 mAh battery, while the iPhone SE 2020 has a smaller 1821 mAh battery. Despite the larger capacity in the S9, real-world battery life can vary based on display technology, software optimization, and usage patterns. Users of the iPhone SE 2020 generally report adequate battery life for moderate daily use, benefiting from the efficiency of its processor and operating system.

The visual experience on these two smartphones differs significantly due to their display technologies and design philosophies.

• Display Technology and Resolution: The Samsung Galaxy S9 features a 5.8-inch Super AMOLED display with a high resolution of 2960 x 1440 pixels, resulting in deep blacks, vibrant colors, and excellent contrast. The iPhone SE 2020 utilizes a 4.7-inch Retina IPS LCD with a resolution of 1334 x 750 pixels. While the LCD offers good color accuracy, it does not achieve the same level of contrast or black depth as an AMOLED panel.
• Screen Size and Design: The Galaxy S9's larger, curved display with minimal bezels provides a more immersive viewing experience, especially for media consumption. The iPhone SE 2020 retains a more traditional design with thicker bezels and a physical home button, resulting in a smaller screen-to-body ratio.
• Brightness and Refresh Rate: Both devices offer sufficient brightness for indoor use. The Galaxy S9's AMOLED panel generally performs well in direct sunlight. Both phones feature a standard 60Hz refresh rate, providing a smooth but not exceptionally fluid scrolling experience compared to devices with higher refresh rates.

Both devices offer capable camera systems for everyday photography, though with different strengths and features.

• Rear Camera Capabilities: The Samsung Galaxy S9 features a 12-megapixel rear camera with a unique variable aperture (f/1.5-f/2.4) that adjusts to lighting conditions, allowing for strong low-light performance. It also includes optical image stabilization (OIS). The iPhone SE 2020 also has a 12-megapixel rear camera with a fixed f/1.8 aperture and OIS. The iPhone benefits from more advanced computational photography, which can enhance image quality, particularly in areas like Portrait mode for people.
• Front Camera and Video: The Galaxy S9 has an 8-megapixel front camera, while the iPhone SE 2020 features a 7-megapixel front camera. Both devices are capable of recording 4K video with their main rear cameras.
• Audio Experience: The Galaxy S9 includes stereo speakers tuned by AKG and retains a 3.5mm headphone jack, offering versatile audio connectivity. The iPhone SE 2020 also has stereo speakers but omits the traditional headphone jack, relying on its Lightning port or wireless audio solutions.
