If you prioritize a better overall camera system with more features and higher video quality, the Samsung Galaxy S21 would be a good choice, though it's more expensive than the A15. However, if battery life and a lower cost are more important to you and you're less concerned with camera capabilities, the Galaxy A15 would suffice. The S21 features a higher screen quality and performance but has a smaller screen. Both phones have plastic bodies and offer 5G connectivity, but only the A15 includes a headphone jack and the S21 offers wireless charging and an IP rating for water and dust resistance.

Huseman Joe | February 2022
"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."
