The Samsung Galaxy S21 Plus 5G and Galaxy S23 both offer a premium Android smartphone experience, but they cater to slightly different priorities. Users often praise the Galaxy S21 Plus 5G for its larger display, which provides an immersive viewing experience for media consumption. Its battery life is generally considered reliable for a full day's use. However, some users might find its camera performance, while good, to be less advanced than newer flagships, particularly in low-light conditions. The S21 Plus 5G also represents an earlier generation of software support, meaning fewer major Android updates remaining compared to its successor.

The Galaxy S23, on the other hand, is frequently lauded for its significantly improved processing power, leading to a smoother and more responsive user experience across all applications, including demanding games. Its camera system, with a higher-resolution main sensor and enhanced low-light capabilities, receives considerable praise for producing detailed and vibrant photos. The S23's more compact size is a notable advantage for those who prefer a device that is easier to handle with one hand. Criticisms are less common but might include its smaller battery capacity compared to the S21 Plus, though its efficiency often compensates for this. The 128GB storage variant using an older UFS standard is also a minor point of consideration for some.

Ultimately, users prioritizing a larger screen and a slightly more substantial feel might lean towards the Galaxy S21 Plus 5G. Conversely, those who value the latest performance, superior camera technology, extended software support, and a more compact form factor will find the Galaxy S23 better suited to their needs. Both devices are excellent choices, and opting for a quality-assured refurbished option can be an eco-friendly alternative for either model.
