If you prioritize having the latest technology and don't mind spending more, the Samsung Galaxy S23 offers higher camera quality for both still photos and videos compared to the S21+. It also has a display with higher peak brightness, which can be useful in outdoor conditions, as well as a more compact design and a faster processor for smoother performance. However, if budget is a main concern and you are comfortable with adequate performance and camera quality, the Galaxy S21+ will offer a larger screen and similar battery life at a more affordable price, making it a good value choice. Both phones support 5G, do not have a headphone jack, and offer similar battery life. Give Feedback

Tom's Guide

Jordan Palmer | May 2022
"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."

The Verge

Allison Johnson | February 2023
"The 6.1-inch S23 is the best reasonably sized Android phone on the market in the US, partly because almost every other Android phone sold here is gigantic. But it’s also a really good device, with a battery that gets through a full day more comfortably than its predecessor. The Snapdragon 8 Gen 2 chipset responsible for some of that battery performance improvement is slightly different — and slightly faster — than the 8 Gen 2 in other Android flagships."
