Galaxy S9 Vs iPhone SE (2020)

The Samsung Galaxy S9, an Android smartphone released in March 2018, and the iPhone SE 2020, an iOS device launched in April 2020, represent distinct approaches to smartphone design and functionality. While the Galaxy S9 offered a premium Android experience with a focus on display technology and camera innovation at its release, the iPhone SE 2020 brought powerful internal components into a more compact, familiar Apple design. These differences extend to their operating systems, with the Galaxy S9 running Android and the iPhone SE 2020 operating on iOS, influencing user experience and software longevity.

When considering the practical lifespan of these devices, their release timelines and software support are key factors. The Galaxy S9, launched in 2018, received major Android OS updates up to Android 10 (One UI 2.5), with security updates continuing for a period thereafter. The iPhone SE 2020, released two years later in 2020, benefits from Apple's typically longer software support, having received updates up to iOS 26.4 as of March 2026.

• Software Longevity: The iPhone SE 2020 offers a longer expected period of major operating system updates and security patches compared to the Galaxy S9, which has reached the end of its official update cycle.
• Physical Durability: Both devices feature glass front and back panels with aluminum frames. The Galaxy S9 uses Corning Gorilla Glass 5, while the iPhone SE 2020 has ion-strengthened glass. The iPhone SE 2020 also carries an IP67 rating for water and dust resistance, offering protection against splashes and submersion up to 1 meter for 30 minutes.
• Repairability: The iPhone SE 2020 generally scores higher in repairability assessments, with some components being interchangeable with the iPhone 8, making common repairs like display and battery replacement relatively straightforward. The Galaxy S9 received a lower repairability score due to its intricate glass construction and strong adhesives, making repairs more challenging.

The performance capabilities of the Galaxy S9 and iPhone SE 2020 reflect their respective release eras and design philosophies. The iPhone SE 2020, being a newer device, incorporates a more recent generation of processing technology, leading to noticeable differences in speed and efficiency.

• Processing Power: The iPhone SE 2020 delivers significantly faster processing speeds, enabling smoother operation for demanding applications, complex multitasking, and graphic-intensive games. The Galaxy S9, while capable at its release, offers performance suitable for everyday tasks and moderate usage.
• System Responsiveness: Users will experience quicker app loading times and more fluid navigation on the iPhone SE 2020 due to its advanced internal components. The Galaxy S9 provides a responsive experience for general use, though it may show signs of slower performance with newer, more resource-intensive applications.
• Battery Behavior: The Galaxy S9 is equipped with a 3000 mAh battery, which typically provides a full day of moderate use, though heavy users might find themselves needing to recharge before the day ends. The iPhone SE 2020 has a smaller 1821 mAh battery, and while optimized for efficiency, heavy usage can also necessitate more frequent charging.

The visual experience on these two smartphones is shaped by their distinct display technologies and design choices.

• Display Technology and Clarity: The Galaxy S9 features a 5.8-inch Super AMOLED display, known for its deep blacks, high contrast, and vibrant colors. It offers a Quad HD+ resolution of 2960x1440 pixels, resulting in a high pixel density of 570 ppi, providing a very sharp and detailed image. The iPhone SE 2020 utilizes a 4.7-inch Retina HD IPS LCD display with a resolution of 1334x750 pixels, yielding 326 ppi. This display offers accurate color reproduction and good viewing angles.
• Brightness and Outdoor Visibility: The Galaxy S9's Super AMOLED panel can reach a peak brightness of up to 1130 nits in high brightness mode, making it highly visible even in direct sunlight. The iPhone SE 2020 has a typical maximum brightness of 625 nits, which is sufficient for most indoor and outdoor conditions.
• Screen Size and Viewing Experience: The Galaxy S9 offers a larger, curved display with a modern 18.5:9 aspect ratio, providing an immersive viewing experience for media consumption. The iPhone SE 2020 has a more compact 4.7-inch screen with a traditional 16:9 aspect ratio and noticeable bezels, which some users may prefer for one-handed use.

Both the Galaxy S9 and iPhone SE 2020 offer capable camera systems, though they differ in their approach and features.

• Rear Camera Capabilities: The Galaxy S9 features a 12-megapixel rear camera with a unique variable aperture (f/1.5-f/2.4), allowing it to adapt to different lighting conditions. It includes Dual Pixel autofocus and optical image stabilization (OIS), and can record 4K video. The iPhone SE 2020 also has a 12-megapixel wide camera with an f/1.8 aperture, OIS, and benefits from advanced image processing for features like Portrait mode and Smart HDR. It supports 4K video recording at up to 60 frames per second.
• Low-Light and Everyday Photography: The Galaxy S9's variable aperture can be advantageous in very low light, allowing more light to reach the sensor. The iPhone SE 2020, while lacking a dedicated night mode, leverages its powerful processor for good low-light performance and excellent everyday photography with accurate colors and detail.
• Front Camera and Video: The Galaxy S9 has an 8-megapixel front camera. The iPhone SE 2020 features a 7-megapixel front camera that supports Portrait mode and 1080p video recording. Both devices offer solid video recording capabilities for their respective generations.
