Galaxy S21 Ultra 5G vs iPhone XS Max

Samsung Galaxy S21 Ultra 5G, a flagship smartphone released in January 2021, and the Apple iPhone XS Max, an earlier premium device launched in September 2018, represent different eras in mobile technology. While both offer large displays and advanced camera systems, the Galaxy S21 Ultra 5G introduces a more modern Android experience with a focus on versatile photography and a highly adaptive screen, whereas the iPhone XS Max provides a refined iOS ecosystem with strong performance for its time.

The practical lifespan of a smartphone is influenced by its release date, software support, and physical resilience. These two devices, separated by over two years, offer different expectations in these areas.

• Release Timeline: The iPhone XS Max, released in September 2018, is an older device compared to the Galaxy S21 Ultra 5G, which launched in January 2021. This difference in age directly impacts their remaining software support window.
• Software Longevity: The Galaxy S21 Ultra 5G, running on Android, typically receives several years of major OS updates and security patches from its release, extending its usability into the future. The iPhone XS Max, an iOS device, has already received numerous updates since its 2018 launch, with user reports indicating it can still run recent iOS versions, though its update cycle is nearing its end compared to the newer Samsung model.
• Physical Durability: Both devices feature robust builds. The iPhone XS Max was noted for using Apple's strongest glass at its release and has an IP68 rating for water and dust resistance, allowing submersion up to 2 meters for 30 minutes. The Galaxy S21 Ultra 5G enhances this with Corning Gorilla Glass Victus on both front and back, offering improved scratch and drop protection, and also carries an IP68 rating.

Performance is a key differentiator, with the newer Galaxy S21 Ultra 5G benefiting from more recent advancements in mobile processing power and memory, while the iPhone XS Max still offers a capable experience for many users.

• Processing Capabilities: The Galaxy S21 Ultra 5G handles demanding applications and intensive multitasking smoothly, providing a responsive experience for gaming, video editing, and complex productivity tasks due to its advanced internal components. The iPhone XS Max, while still performing well for everyday use, web browsing, and most applications, may show its age with the most graphically intensive games or when running many applications simultaneously.
• Multitasking and Storage: The Galaxy S21 Ultra 5G comes with higher RAM configurations, offering 12GB or 16GB, which allows for more applications to run in the background without needing to reload. The iPhone XS Max typically features 4GB of RAM. Both devices offer various internal storage options, including 128GB, 256GB, and 512GB, providing ample space for apps and media.
• Battery Behavior: The Galaxy S21 Ultra 5G is equipped with a larger 5000 mAh battery, consistently delivering a full day of use, even with its high-refresh-rate display enabled. Users report screen-on times often exceeding 10 hours. The iPhone XS Max, with its 3174 mAh battery, generally provides a full day of moderate usage, with some users reporting 10-12 hours under typical conditions. Both support fast charging and wireless charging.

Both smartphones feature large, vibrant displays, but the Galaxy S21 Ultra 5G incorporates newer display technology that offers a more dynamic visual experience.

• Display Technology and Clarity: Both devices utilize OLED technology, known for deep blacks and high contrast. The iPhone XS Max features a 6.5-inch Super Retina HD OLED display with a resolution of 2688x1242 pixels, resulting in a pixel density of 458 ppi. The Galaxy S21 Ultra 5G boasts a larger 6.8-inch Dynamic AMOLED 2X display with a higher resolution of 3200x1440 pixels (QHD+), yielding a pixel density of 515 ppi, providing a slightly sharper image.
• Brightness and Refresh Rate: The Galaxy S21 Ultra 5G offers significantly higher peak brightness, reaching up to 1500 nits, which improves outdoor visibility and HDR content viewing. The iPhone XS Max has a maximum brightness of 625 nits. A key advantage of the S21 Ultra 5G is its adaptive refresh rate, ranging from 10Hz to 120Hz, which provides smoother scrolling and more fluid animations while conserving battery life. The iPhone XS Max has a standard 60Hz refresh rate.
• Viewing Experience: The larger screen size and higher resolution of the Galaxy S21 Ultra 5G, combined with its adaptive refresh rate, offer a more immersive and fluid viewing experience, particularly for media consumption and gaming. The iPhone XS Max still delivers an excellent visual experience with its color accuracy and HDR support.

The camera systems on both devices are capable, but the Galaxy S21 Ultra 5G offers a more versatile setup with advanced zoom capabilities and higher megapixel counts.

• Rear Camera System: The Galaxy S21 Ultra 5G features a quad-camera setup, including a 108MP wide-angle lens, a 12MP ultrawide lens, and two 10MP telephoto lenses (one with 3x optical zoom and another with 10x optical zoom), enabling up to 100x digital 'Space Zoom'. This provides exceptional flexibility for various photography scenarios, from wide landscapes to distant subjects. The iPhone XS Max has a dual 12MP camera system, consisting of a wide-angle lens and a telephoto lens, both with optical image stabilization, offering 2x optical zoom and up to 10x digital zoom.
• Photography Performance: The S21 Ultra 5G excels in detail capture, especially with its 108MP sensor and advanced zoom. Its low-light performance is strong, and it offers a wide dynamic range. The iPhone XS Max captures high-quality photos with natural colors and good dynamic range in ample light, and its Portrait mode with Depth Control is well-regarded.
• Video Recording and Audio: The Galaxy S21 Ultra 5G supports 8K video recording at 24fps, along with 4K at 30/60fps and various slow-motion options. The iPhone XS Max records 4K video at 24, 30, or 60fps and 1080p at up to 240fps for slow-motion, and was one of the first iPhones to record stereo audio for videos. Both offer good microphone quality for calls and recording, and stereo speakers for media consumption.
