Galaxy S21 FE 5G Vs Galaxy S25+

The Samsung Galaxy S21 FE 5G, released in January 2022, and the Samsung Galaxy S25 Plus, launched in February 2025, represent different generations within Samsung's smartphone lineup. While both devices operate on the Android platform, the S25 Plus introduces significant advancements in processing power, camera capabilities, and long-term software support, reflecting its newer release. These differences cater to varying user needs, from those seeking a reliable, established device to those prioritizing the latest technology and extended longevity.

The expected lifespan and software support differ considerably between these two devices, primarily due to their respective release dates and Samsung's evolving update policies.

• Release Timeline and Age: The Galaxy S21 FE 5G, released in January 2022, is an older model compared to the Galaxy S25 Plus, which launched in February 2025. This age difference directly impacts their remaining support windows.
• OS Support Duration: The Galaxy S21 FE 5G launched with Android 12 and is expected to receive four major OS updates, concluding with Android 16. It also receives security updates for five years, with a shift to a quarterly schedule in late 2025. In contrast, the Galaxy S25 Plus, launching with Android 15, benefits from Samsung's extended commitment of seven generations of OS upgrades and seven years of security updates, meaning support until approximately 2032.
• Practical Lifespan: Users prioritizing the longest possible software and security support will find the Galaxy S25 Plus offers a significantly extended practical lifespan, ensuring access to new features and protection against vulnerabilities for many more years. The S21 FE 5G, while still receiving updates, is nearing the end of its major software support cycle.

Performance is a key area where the newer Galaxy S25 Plus demonstrates a notable advantage over the Galaxy S21 FE 5G, impacting overall system responsiveness and handling of demanding applications.

• Processor Capabilities: The Galaxy S21 FE 5G is powered by a processor that, while capable for its time, can show its age with very demanding tasks or prolonged heavy use, sometimes leading to noticeable warmth. The Galaxy S25 Plus features a current-generation processor designed for enhanced efficiency and raw power, resulting in smoother operation, faster app loading, and more fluid multitasking, even with intensive applications and gaming.
• Multitasking and Responsiveness: The Galaxy S25 Plus typically includes a larger amount of RAM (12GB as standard) compared to the S21 FE 5G (6GB or 8GB), which contributes to its ability to manage numerous open applications and switch between them without hesitation. This translates to a more consistently responsive user experience on the S25 Plus.
• Storage Options: Both devices offer ample internal storage, with the S21 FE 5G available in 128GB and 256GB configurations, and the S25 Plus starting at 256GB and extending to 512GB or 1TB options, providing more headroom for large files and applications.

Both devices feature high-quality AMOLED displays, but the Galaxy S25 Plus offers advancements in resolution, brightness, and refresh rate adaptability for a more refined visual experience.

• Display Technology and Clarity: Both phones utilize Dynamic AMOLED 2X technology, known for vibrant colors and deep blacks. The Galaxy S21 FE 5G has a 6.4-inch display with a Full HD+ resolution (1080 x 2400 pixels), providing clear visuals for everyday use. The Galaxy S25 Plus features a larger 6.7-inch display with a Quad HD+ resolution (1440 x 3120 pixels), resulting in a noticeably sharper image with finer detail.
• Brightness and Refresh Rate: The S21 FE 5G offers a 120Hz refresh rate for smooth scrolling, though it is not adaptive, meaning it consistently operates at 120Hz or 60Hz, which can impact battery consumption. The S25 Plus also boasts a 120Hz refresh rate, but it is adaptive, allowing the screen to dynamically adjust its refresh rate based on content, optimizing both smoothness and power efficiency. The S25 Plus also achieves significantly higher peak brightness levels, improving outdoor visibility.
• Viewing Experience: Users who consume a lot of media or require precise visual detail will appreciate the larger, higher-resolution, and brighter display of the Galaxy S25 Plus. The S21 FE 5G still provides a good viewing experience, particularly for its class.

The camera systems on both smartphones are capable, but the Galaxy S25 Plus benefits from newer sensor technology and enhanced processing, leading to more versatile and higher-quality imaging.

• Main Camera Performance: The Galaxy S21 FE 5G features a 12 MP main camera with optical image stabilization (OIS), performing well in good lighting conditions but showing limitations in low-light environments. The Galaxy S25 Plus steps up with a 50 MP main camera, also with OIS, which captures more detail and generally excels in a wider range of lighting conditions, including improved low-light photography.
• Telephoto and Ultrawide: The S21 FE 5G includes an 8 MP telephoto lens with 3x optical zoom and a 12 MP ultrawide camera. The 8 MP telephoto is often cited as the weakest link in its camera array. The S25 Plus offers a 10 MP telephoto lens with 3x optical zoom and a 12 MP ultrawide camera, providing more consistent image quality across all lenses and better detail retention, especially at zoom levels.
• Video Recording and Front Camera: Both devices support 4K video recording, with the S25 Plus capable of 8K video at 30fps from its main camera and 10-bit HDR video recording across all cameras. The S21 FE 5G has a 32 MP front camera, while the S25 Plus features a 12 MP front camera, both capable of capturing detailed selfies and video calls.
