The Galaxy S21 5G is Samsung's 2021 flagship, a 6.4-inch phone with a 120Hz Dynamic AMOLED 2X screen, Snapdragon 888-class performance and a 4,500 mAh battery. It stands out for its bright, smooth display, compact size for a flagship and wireless charging. It holds up against newer mid-range phones on screen and build, but its average battery life and fixed 128 GB storage are the main trade-offs.
