Galaxy S21 5G Vs iPhone 16 Plus

The Samsung Galaxy S21 5G, released in January 2021, and the iPhone 16 Plus, launched in September 2024, represent different generations and operating system ecosystems. While the Galaxy S21 5G runs on Android, offering a customizable experience, the iPhone 16 Plus operates on Apple's iOS, known for its integrated ecosystem and long-term software support. Key differentiators include their respective release timelines, display technologies, and camera system philosophies.

The practical lifespan of a smartphone is heavily influenced by its release date and the manufacturer's commitment to software updates and repairability.

• Release Timeline: The Galaxy S21 5G was introduced in early 2021, making it a device from a previous generation. The iPhone 16 Plus, released in late 2024, benefits from being a much newer model.
• Software Longevity: The Galaxy S21 5G launched with Android 11 and received major OS updates up to Android 15 (One UI 7), with security updates extending until early 2026, after which they became quarterly and have now ended. [9, 13, 21, 33] In contrast, the iPhone 16 Plus, launching with iOS 18, is expected to receive major iOS updates for a minimum of five years from its release date, likely extending to seven years or more, offering a significantly longer period of software support.

• Repairability: While both manufacturers offer repair services, the iPhone 16 Plus features an internal design that facilitates easier battery replacements compared to previous models, potentially extending its usable life. [6]

Performance is a critical aspect for daily use, encompassing how smoothly applications run, the device's responsiveness, and its ability to handle demanding tasks.

• System Responsiveness: The Galaxy S21 5G, powered by its generation's flagship processors (Exynos 2100 or Snapdragon 888), delivers smooth performance for everyday applications and multitasking. [1, 12, 15] The iPhone 16 Plus, featuring a newer generation processor, offers enhanced speed and efficiency, resulting in quicker app loading times and a more fluid user experience, especially with more intensive applications and future software features like Apple Intelligence.

• Multitasking and Storage: Both devices come with 8GB of RAM, allowing for efficient multitasking. [1, 12, 15, 18, 30] The Galaxy S21 5G offers 128GB or 256GB of internal storage, without expandable options. [1, 12, 15, 27] The iPhone 16 Plus provides more storage flexibility with options up to 512GB. [4, 5, 7, 34]
• Battery Behavior: The Galaxy S21 5G is equipped with a 4000 mAh battery, providing approximately 1.5 days of typical use, or around 10 hours of Wi-Fi streaming. [1, 12, 27, 32, 36] The iPhone 16 Plus, with its 4674 mAh battery and more efficient components, offers extended usage times, rated for up to 27 hours of video playback and 24 hours of streaming video.

• Brightness and Smoothness: The Galaxy S21 5G's display can reach a peak brightness of 1300 nits and features an adaptive 120Hz refresh rate, providing smooth scrolling and responsive interactions. [24, 29] The iPhone 16 Plus offers higher peak brightness for outdoor use at 2000 nits, but it maintains a fixed 60Hz refresh rate, which means animations and scrolling may not appear as fluid as on the Galaxy S21 5G.
