Galaxy S9 • Unlocked vs iPhone 12 Pro • Unlocked

The Samsung Galaxy S9, released in March 2018, and the iPhone 12 Pro, launched in October 2020, represent different eras and operating systems within the smartphone landscape. While both were flagship devices at their respective launches, they cater to distinct user preferences and offer varying capabilities. The primary distinctions lie in their operating systems, overall performance, and camera systems, reflecting the technological advancements over their two-and-a-half-year release gap.

When considering the practical lifespan of these devices, their release timelines and software support cycles are key factors.

• Release Timeline: The Galaxy S9 was introduced in early 2018, making it an older device compared to the iPhone 12 Pro, which arrived in late 2020. This age difference directly impacts the remaining period of official software updates and security patches.
• OS Support Duration: The iPhone 12 Pro, running on iOS, typically receives software updates for a longer duration than Android devices of a similar age. The Galaxy S9 likely concluded its major Android OS updates around Android 10 or 11, while the iPhone 12 Pro continues to receive the latest iOS versions, extending its software longevity.
• Expected Practical Lifespan: Users prioritizing the latest software features and security updates will find the iPhone 12 Pro offers a longer practical lifespan. Both devices feature robust build quality, with the iPhone 12 Pro introducing Ceramic Shield for enhanced front cover durability and both offering IP68 water and dust resistance.

The performance of a smartphone is crucial for daily operations, from launching applications to handling demanding tasks.

• Processing Capabilities: The iPhone 12 Pro features a newer generation processor, which translates to noticeably faster application loading times, smoother multitasking, and more responsive performance in graphically intensive games and advanced applications. The Galaxy S9, while powerful for its release year, will exhibit slower speeds in comparison, particularly with newer software and more complex tasks.
• Storage Options: The Galaxy S9 was available with storage options up to 256GB, with the added flexibility of expandable storage via a microSD card. The iPhone 12 Pro starts with a base storage of 128GB and goes up to 512GB, but does not offer expandable storage.
• Battery Behavior: The iPhone 12 Pro's battery capacity is 2815 mAh, while the Galaxy S9 has a 3000 mAh battery. Despite the Galaxy S9's slightly larger capacity, its older processor and software optimizations may result in comparable or even shorter real-world battery life for heavy users, especially given the natural degradation of older batteries. The iPhone 12 Pro's power-efficient processor generally provides reliable power management for a full day of typical use, though 5G connectivity can increase power consumption.

The display is a primary interface for smartphone interaction, and both devices offer high-quality viewing experiences with some notable differences.

• Display Technology and Resolution: Both the Galaxy S9 and iPhone 12 Pro feature OLED display technology, known for deep blacks and vibrant colors. The Galaxy S9 has a 5.8-inch Super AMOLED display with a resolution of 2960x1440 pixels, resulting in a pixel density of 570 ppi. The iPhone 12 Pro has a 6.1-inch Super Retina XDR OLED display with a resolution of 2532x1170 pixels, offering 460 ppi.
• Brightness and Clarity: The iPhone 12 Pro's Super Retina XDR display offers higher peak brightness, reaching up to 1200 nits for HDR content, which provides better visibility in bright outdoor conditions and a more impactful HDR viewing experience. The Galaxy S9's display also supports HDR10 and offers good brightness for its generation.
• Screen Size and Viewing Experience: The iPhone 12 Pro offers a slightly larger 6.1-inch display compared to the Galaxy S9's 5.8-inch screen, providing a marginally more expansive viewing area. Both displays operate at a standard 60Hz refresh rate.

Camera capabilities are a significant consideration for many users, and these two devices offer different approaches to mobile photography.

• Camera System Configuration: The Galaxy S9 features a single 12-megapixel rear camera with a unique variable aperture (f/1.5 and f/2.4) designed to adapt to different lighting conditions. The iPhone 12 Pro boasts a more versatile triple 12-megapixel camera system, including a wide (f/1.6), ultra-wide (f/2.4), and telephoto (f/2.0) lens, along with a LiDAR Scanner for improved low-light focusing and augmented reality.
• Photography Performance: The iPhone 12 Pro excels in low-light photography with its dedicated Night mode and Deep Fusion processing, producing detailed and well-exposed images in challenging conditions. Its telephoto lens also provides optical zoom capabilities. The Galaxy S9's variable aperture was innovative for its time, allowing it to capture more light in dark environments, and it was praised for its overall image quality upon release.
• Video Recording Quality: The iPhone 12 Pro supports HDR video recording with Dolby Vision at up to 60 frames per second, offering professional-grade video capture with enhanced dynamic range and color accuracy. The Galaxy S9 can record 4K video at 60 frames per second and features a notable super slow-motion mode at 720p and 960 frames per second.
