Galaxy S21 FE 5G • Locked Verizon vs OnePlus 12 • Unlocked

The Samsung Galaxy S21 FE 5G, released in January 2022, and the OnePlus 12, launched globally in February 2024, are both Android smartphones that cater to different user expectations. While the Galaxy S21 FE offers a balanced experience from a well-established series, the OnePlus 12 arrives with more recent hardware advancements and a focus on high-end performance. Both devices run on the Android operating system, but their release timelines mean they are at different stages of their software support cycles.

The practical lifespan of a smartphone is influenced by its release date, software support, and physical durability. These factors determine how long a device remains functional and secure for daily use.

• Release Timeline and Age: The Galaxy S21 FE 5G was released in January 2022, making it over two years older than the OnePlus 12, which launched globally in February 2024. This age difference directly impacts the remaining period of official software support and the longevity of its internal components.
• OS Support Duration: The Galaxy S21 FE typically receives four years of major Android OS updates and five years of security patches from its release. Having launched with Android 12, it is likely nearing the end of its major OS update cycle. In contrast, the OnePlus 12, launching with Android 14, is promised four years of Android updates and five years of security patches, extending its software relevance further into the future.
• Repairability and Durability: Both devices feature robust build quality. The Galaxy S21 FE comes with an IP68 rating for dust and water resistance, and its display is protected by Gorilla Glass Victus. The OnePlus 12 offers an IP65 rating for dust and water resistance and features the newer Gorilla Glass Victus 2 for enhanced screen protection. User reports suggest the OnePlus 12 has moderate repairability, with some components like the battery being accessible, though strong adhesives are used.

Performance is a critical aspect for users, dictating how smoothly applications run, how quickly tasks are completed, and the overall responsiveness of the device. The core components driving these experiences differ between the two models.

• Processor Capabilities: The Galaxy S21 FE 5G is equipped with a processor capable of handling everyday applications and multitasking efficiently. For more demanding tasks or graphics-intensive games, it provides a solid but not leading-edge experience. The OnePlus 12, featuring a significantly newer generation processor, delivers a more powerful and responsive experience, excelling in heavy multitasking, advanced gaming, and complex computational tasks.
• RAM and Storage: The Galaxy S21 FE typically comes with 6GB or 8GB of RAM and 128GB or 256GB of internal storage. The OnePlus 12 offers higher configurations, starting with 12GB or 16GB of RAM and 256GB or 512GB of faster UFS 4.0 storage, which contributes to quicker app loading and smoother data handling.
• Battery Behavior: The Galaxy S21 FE houses a 4500 mAh battery, providing sufficient power for a full day of moderate use. The OnePlus 12 features a larger 5400 mAh battery, often reported by users to last up to two days on a single charge with typical usage, and supports significantly faster wired and wireless charging.

The display is the primary interface for user interaction, and its quality significantly impacts the viewing experience, from casual browsing to multimedia consumption.

• Display Technology and Resolution: Both devices feature AMOLED displays, known for vibrant colors and deep blacks. The Galaxy S21 FE 5G has a 6.4-inch Dynamic AMOLED 2X display with FHD+ resolution (1080 x 2340 pixels). The OnePlus 12 boasts a larger 6.82-inch LTPO AMOLED display with a higher QHD+ resolution (3168 x 1440 pixels), offering greater clarity and detail.
• Brightness and Refresh Rate: Both phones offer a smooth 120Hz refresh rate for fluid scrolling and responsiveness. However, the OnePlus 12 stands out with a significantly higher peak brightness of up to 4500 nits, making it exceptionally visible even in bright outdoor conditions, compared to the Galaxy S21 FE's generally good but lower brightness levels. The OnePlus 12 also features LTPO technology, allowing its refresh rate to dynamically adjust from 1Hz to 120Hz, which can contribute to power efficiency.
• Viewing Experience: The larger, higher-resolution display of the OnePlus 12 provides a more expansive and immersive viewing experience, particularly for video content and detailed graphics. The Galaxy S21 FE's display remains excellent for its class, offering a clear and vibrant picture suitable for most users.

Camera capabilities are a key consideration for many users, influencing the quality of photos and videos captured in various scenarios.

• Rear Camera Systems: The Galaxy S21 FE 5G features a versatile triple-camera setup with a 12MP wide, 12MP ultra-wide, and an 8MP telephoto lens with 3x optical zoom. The OnePlus 12, with its 4th Generation Hasselblad Camera System, offers a more advanced array: a 50MP main sensor, a 48MP ultra-wide, and a 64MP telephoto lens with 3x optical zoom and 6x in-sensor zoom.
• Photography Performance: The Galaxy S21 FE delivers consistent and good quality photos in well-lit conditions, with its telephoto lens providing useful zoom capabilities. The OnePlus 12, with its larger main sensor and Hasselblad tuning, generally produces images with enhanced detail, improved color accuracy, and better low-light performance. Its telephoto lens also offers greater versatility with higher resolution and in-sensor zoom.
• Video and Audio: Both phones are capable of recording high-quality video. The OnePlus 12 supports up to 8K video recording at 24 FPS and 4K at 30/60 FPS, with the ability to switch between lenses while recording 4K 60fps. The OnePlus 12 also features dual stereo speakers with Dolby Atmos for an enhanced audio experience.
