Galaxy S8 vs Galaxy S21 5G


Swappasaurus says...

Choosing to upgrade from the Galaxy S8 to the Galaxy S21 means skipping several generations, which will lead to a large boost in overall performance. The Galaxy S21 is powered by an 8-Core Qualcomm Snapdragon 888 processor, and the Snapdragon 835 powers the Galaxy S8. Another immediately noticeable improvement is the display, which grows in size due and quality. The display on the Galaxy S8 measures 5.8-inches, and the Galaxy S21 brings that to 6.2-inches. The S21 display is FHD+ Dynamic AMOLED 2x with a resolution of 2400 x 1080 and a refresh rate of up to 120Hz. You would also be getting an improved camera setup, with the front-facing camera going from an 8MP on the S8 to a 10MP on the S21, and the rear-camera going from a single 12MP on the S8 to a triple camera array with a 12MP wide, 12MP ultrawide, and 64MP telephoto on the S21. Other highlight features on the Galaxy S21 include a 4000 mAh battery, 8GB of RAM, and up to 256GB of internal storage space.
