Scores

Durability

When considering the long-term usability of these devices, their respective release timelines and software support policies are key factors.

  • Release Timeline: The Galaxy S21 5G was released in January 2021, making it an older device compared to the Galaxy A23 5G, which launched in late 2022. This age difference impacts the remaining duration of official software support.
  • OS Support Duration: The Galaxy S21 5G, as a former flagship, was promised four years of major Android updates and five years of security updates from its release. This means its major OS updates likely concluded in 2025. The Galaxy A23 5G, a mid-range device, typically receives a commitment of four years of software support, with Android 14 likely being its last major Android update. Users prioritizing the latest Android versions for the longest possible time might find the A23 5G has slightly more runway for major OS updates from its later starting point, though the S21 5G will continue to receive security patches for a period. [9, 22]
  • Practical Lifespan: Both devices are built to last, but the Galaxy S21 5G features an IP68 rating for dust and water resistance, offering an additional layer of protection against environmental elements that the Galaxy A23 5G lacks. [13, 18] The Galaxy A23 5G does feature Gorilla Glass 5 for screen protection, providing a good level of durability against drops and scratches. [5, 7]

Performance

The performance of a smartphone is largely determined by its internal components, influencing how smoothly applications run and how efficiently it handles demanding tasks.

  • Processing Power: The Galaxy S21 5G is equipped with a processor designed for high-end performance, enabling it to handle graphically intensive games and complex applications with ease and responsiveness. [18, 39] In contrast, the Galaxy A23 5G features a mid-range processor that provides snappy performance for everyday tasks and multitasking. While it can manage graphically demanding games, users might experience minimal stuttering at lower graphics settings during extended play. [16, 22, 24]
  • Multitasking and Storage: The Galaxy S21 5G typically comes with 8GB of RAM, facilitating smooth transitions between multiple open applications. It offers 128GB or 256GB of internal storage, but it does not support expandable storage via a microSD card. [13, 23] The Galaxy A23 5G is available with 4GB, 6GB, or 8GB of RAM and 64GB or 128GB of internal storage, with the added flexibility of a microSD card slot for storage expansion up to 1TB. [1, 6]
  • Battery Behavior: The Galaxy A23 5G houses a larger 5000mAh battery, which, combined with its power-efficient processor, often allows for extended usage, with many users reporting up to a day and a half or even two days of power on a single charge. [5, 11, 22, 30] The Galaxy S21 5G has a 4000mAh battery, generally providing a full day of use for most users, though heavy usage may require more frequent charging. [10, 18, 39]

The camera systems on both the Galaxy A23 5G and Galaxy S21 5G are designed to capture moments, but they differ in their capabilities and features.

  • Rear Camera System: The Galaxy S21 5G boasts a versatile triple-camera setup, including a 12MP main sensor with optical image stabilization (OIS), a 12MP ultrawide lens, and a 64MP telephoto lens capable of 3x hybrid optical zoom. This configuration allows for a wide range of photographic styles, from expansive landscapes to detailed zoomed-in shots. [14, 23, 35] The Galaxy A23 5G features a quad-camera system with a 50MP main sensor (with OIS), a 5MP ultrawide, a 2MP macro, and a 2MP depth sensor. The main camera performs well in good lighting, but the ultrawide and other auxiliary lenses offer more modest performance. [1, 5, 6, 7, 22]
  • Photography Performance: The Galaxy S21 5G delivers excellent photo quality across its lenses, with strong low-light performance and improved software processing. [2, 10, 35, 42] The Galaxy A23 5G's main camera captures good detail and color in well-lit conditions, and its night mode is serviceable. However, its ultrawide camera shows a noticeable drop in quality, and indoor photography can be a weaker area. [5, 6, 32]
  • Video Recording and Front Camera: The Galaxy S21 5G offers advanced video recording capabilities, including up to 8K resolution at 24fps and 4K at 60fps, making it suitable for users who prioritize high-quality video content. Its 10MP front camera also provides clear selfies. [17, 23, 40] The Galaxy A23 5G records video at 1080p at 30fps from both its main and 8MP selfie cameras, which is adequate for casual use but less capable for professional-grade video. [5, 6, 19]

The Samsung Galaxy A23 5G and Galaxy S21 5G offer distinct propositions for smartphone users. User feedback for the Galaxy A23 5G frequently praises its exceptional battery life, with many reporting multi-day usage, and its smooth 120Hz display. [11, 22, 30] Some users note that while its main camera is capable in good lighting, video recording quality is not its strongest suit. [5, 6, 32] The Galaxy S21 5G, on the other hand, is often lauded for its powerful performance, vibrant AMOLED display, and versatile camera system, particularly its video capabilities. [10, 18, 39, 40] However, some users have noted that its battery life, while generally good for a day, might not be as long-lasting as devices with larger batteries, and the absence of expandable storage is a common point of discussion. [20, 39]

Users prioritizing extended battery life, expandable storage, and a headphone jack for everyday convenience may find the Galaxy A23 5G to be a well-suited option. It delivers a solid experience for general use, social media, and casual gaming. Conversely, individuals who demand higher processing power for intensive applications, a more advanced camera system with superior video recording, and a more compact design with enhanced water and dust resistance will likely lean towards the Galaxy S21 5G. Both devices offer a reliable Android experience, and choosing a quality-assured refurbished option for either model can be an eco-friendly alternative for consumers.
