If you prioritize camera quality, the Samsung Galaxy S21+ offers a better overall camera experience including higher quality photos and videos, particularly in HDR and low light situations. In contrast, the Galaxy A25 has a more modest camera setup with lower performance in these areas. For those concerned with battery life, the A25 edges out slightly, providing slightly longer usage per charge. Screen size is similar, but the S21+ has a slightly larger and higher-quality display, and both phones have high refresh rates for smooth visuals. If operating system updates and support are essential, consider that the S21+ is older and may receive updates for a shorter period than the newer A25. The choice between plastic and glass backs might influence durability and design preference, with the A25 featuring plastic and the S21+ glass. Overall, if camera and screen quality are more critical for you and you don't mind potentially shorter support timelines, the slightly less expensive S21+ could be the better option; if battery life and potentially longer software support are higher priorities at a slightly higher price, consider the A25.

"All told, Samsung nailed it with the Galaxy S21 Plus. It has most of the strengths of the smaller S21 in a bigger package. It’s got a lot going for it. If you’re coming from an older device, like the Galaxy S10 series, this is a solid upgrade."
