If camera quality is important to you, the Samsung Galaxy S21 stands out with better photo and video capabilities. It also has a sharper screen with a higher refresh rate, which makes for smoother visuals. The S21 is lighter and comes with more storage, but if you're looking for longer battery life, the Samsung Galaxy A13 will last longer on a single charge. Both have plastic backs and run on Android, but the S21 does not have a headphone jack, whereas the A13 does, which might be important if you use wired headphones. Keep in mind, the S21 supports 5G whereas the A13 does not. Give Feedback

"The Galaxy S21 delivers the flagship Samsung experience in a phone that's much more pocketable (and affordable) than the top-end S21 Ultra.The triple-camera system is incredibly capable, Samsung's One UI 3.1 software is chock-full of features and settings to mess with, and I've not once missed having expandable storage."
