Ratings

The Samsung Galaxy S20 Plus 5G, released in March 2020, and the Samsung Galaxy S21 5G, launched in January 2021, represent consecutive generations of Samsung's flagship smartphone line. While both devices offer 5G connectivity and run on the Android operating system with Samsung's One UI, the S21 5G introduced a refined design, an updated processor, and some camera enhancements. This comparison will explore the practical differences between these two models to help users determine which device best suits their needs.

Scores

Durability

When considering the long-term usability of a smartphone, software support and physical resilience are key factors. The Galaxy S20 Plus 5G and Galaxy S21 5G offer different timelines for updates and varying levels of material durability.

  • Software Longevity: The Galaxy S20 Plus 5G, launched with Android 10, received its last major OS update with Android 13 and concluded security updates around March 2025. The Galaxy S21 5G, released with Android 11, received its final major OS update with Android 15 in May 2025, with security updates ending around November 2025 or February 2026. This means the S21 5G benefits from a slightly longer period of official software support.
  • Physical Durability: The S20 Plus 5G features Corning Gorilla Glass 6 on both its front and back, providing a good level of scratch and drop resistance. The S21 5G upgrades the front display protection to Gorilla Glass Victus, which offers improved resistance against drops and scratches. However, the standard S21 5G model utilizes a 'Glasstic' (polycarbonate) back, which some users may perceive differently compared to the glass back of the S20 Plus 5G. Both devices carry an IP68 rating for dust and water resistance, indicating protection against immersion in up to 1.5 meters of fresh water for 30 minutes.
  • Repairability: While specific repairability scores can vary, both models are designed with modern smartphone construction, meaning repairs often require specialized tools and expertise. The lack of a user-replaceable battery in both devices is a common characteristic of contemporary smartphones.

Performance

The performance of a smartphone significantly impacts daily usage, from launching applications to handling demanding tasks. Both the Galaxy S20 Plus 5G and Galaxy S21 5G deliver capable performance, though with generational differences.

  • Processing Power: The Galaxy S21 5G features a newer generation processor compared to the S20 Plus 5G. This translates to a noticeable boost in overall performance, particularly for intensive applications and gaming. Users will experience faster app loading times and smoother transitions on the S21 5G.
  • Multitasking and Responsiveness: The S20 Plus 5G typically came with 12GB of RAM, offering substantial capacity for multitasking and keeping numerous applications open in the background without slowdowns. The standard S21 5G, on the other hand, generally includes 8GB of RAM. While 8GB is sufficient for most users, those who frequently switch between many demanding applications might notice a slight difference in sustained multitasking performance.
  • Storage Options: The S20 Plus 5G offered more flexible storage options, including configurations up to 512GB and the inclusion of a microSD card slot for expandable storage. The S21 5G, while offering 128GB and 256GB options, notably removed the microSD card slot, meaning users are limited to the internal storage chosen at purchase.
  • Battery Behavior: The S20 Plus 5G is equipped with a 4500mAh battery, while the S21 5G has a 4000mAh battery. Despite the S21 5G's smaller battery, its more efficient processor and adaptive refresh rate display can contribute to optimized power consumption. However, some S21 5G users have reported battery drain issues, particularly after certain software updates.

Screen quality

The display is a primary interface for smartphone interaction, and both the Galaxy S20 Plus 5G and S21 5G offer high-quality viewing experiences with some notable distinctions.

  • Display Technology and Size: Both devices feature Dynamic AMOLED 2X displays, known for vibrant colors, deep blacks, and excellent contrast. The S20 Plus 5G has a larger 6.7-inch display, providing more screen real estate for media consumption and productivity. The S21 5G features a slightly more compact 6.2-inch display.
  • Resolution and Clarity: The S20 Plus 5G boasts a higher resolution display at 1440 x 3200 pixels, offering a sharper image with greater pixel density. The S21 5G has a resolution of 1080 x 2400 pixels. While both provide a clear viewing experience, the S20 Plus 5G offers finer detail, especially noticeable when viewing high-resolution content.
  • Refresh Rate and Smoothness: Both models support a 120Hz refresh rate for smoother scrolling and more fluid animations. On the S20 Plus 5G, the 120Hz refresh rate is available at FHD+ resolution. The S21 5G features an adaptive refresh rate that can dynamically adjust between 48Hz and 120Hz, optimizing battery life by lowering the refresh rate when static content is displayed.
  • Brightness: Both displays offer high peak brightness levels, ensuring good visibility even in bright outdoor conditions. The S21 5G's display can reach up to 1300 nits of peak brightness.

Miscellaneous

Beyond core performance and display, several practical elements contribute to the overall user experience of these smartphones.

  • Connectivity: Both the Galaxy S20 Plus 5G and S21 5G support 5G networks, along with Wi-Fi 6 (802.11ax) and Bluetooth 5.0 (S20 Plus 5G) or 5.1 (S21 5G). The S21 5G may offer slightly better 5G technology and connectivity.
  • Ports and Sensors: Neither device includes a 3.5mm headphone jack. Both utilize a USB-C port for charging and data transfer. For security, both feature an in-display fingerprint sensor and support face recognition. The S21 5G's fingerprint sensor is noted by some users as being larger and more responsive.
  • Design and Materials: The S20 Plus 5G features an aluminum frame with Gorilla Glass 6 on both the front and back, giving it a premium feel. The standard S21 5G also has an aluminum frame but uses Gorilla Glass Victus on the front and a 'Glasstic' (polycarbonate) material for the back panel. This material choice on the S21 5G can make it feel less premium to some users, though it can also be more resistant to shattering.
  • Dimensions and Weight: The S20 Plus 5G measures 161.9 x 73.7 x 7.8 mm and weighs 188 grams. The S21 5G is more compact at 151.7 x 71.2 x 7.9 mm and lighter at 169 grams. This difference in size and weight can impact one-handed usability and pocketability.

User feedback for both the Galaxy S20 Plus 5G and Galaxy S21 5G highlights their strengths and areas for consideration. The S20 Plus 5G was generally praised for its high-resolution display, expandable storage, and larger battery. However, some users reported issues with overheating, particularly with the Exynos variant, and microphone problems. The S21 5G, while appreciated for its updated processor, improved camera software, and more compact design, faced some criticism regarding its 'Glasstic' back, the removal of the microSD card slot, and occasional battery drain concerns.

For users prioritizing a larger, higher-resolution display and the flexibility of expandable storage, the Galaxy S20 Plus 5G remains a compelling option. Its glass back also offers a more premium feel. Conversely, those who value a more compact form factor, a newer processor for enhanced performance, and slightly longer software support will find the Galaxy S21 5G well-suited to their needs. The S21 5G also offers a more robust front display glass. Both devices provide a strong Android experience with 5G capabilities.

When making a decision, considering a quality-assured refurbished option for either model can be an eco-friendly alternative, offering a sustainable choice for acquiring these capable smartphones.
