Galaxy S8 vs Galaxy S21 Plus 5G

Swappasaurus says...
Upgrading from the Galaxy S8 to the Galaxy S21 Plus will result in a big boost in terms of performance, and also a noticeable difference in the display size and quality. The improved performance comes by way of the new 8-Core Qualcomm Snapdragon 888 processor that powers the Galaxy S21 Plus, which is paired with 8GB of RAM. The display size increases by nearly a full inch, going from 5.8-inches on the S8 to 6.7-inches on the S21 Plus. Highlight features for the S21 Plus display include a refresh rate of up to 120Hz and a resolution of 2400 x 1080. The remaining specs for the S21 Plus include a 10MP selfie camera, a 12MP wide, 12MP ultrawide, and 64MP telephoto camera array on the back, a 4000 mAh battery, and options for 128GB or 256GB of internal storage space.
