Samsung Galaxy S21 5G technical sheet
The Samsung Galaxy S21 5G suits anyone looking for a compact phone with a standout display and wireless charging; its 4,000 mAh battery and 12 MP main camera are the main trade-offs. The 6.2″ display combines a 120 Hz refresh rate, 421 ppi and peak brightness of 1,300 nits. Its refresh rate is better than most phones of its time, while pixel density and brightness are among the best. At 169 g, it is lighter than most phones launched around the same time, and its body is 7.9 mm thick. IP68 protection adds to its practical compact design.
Performance is better than most phones of its time, with an Exynos 2100 and 8 GB of RAM in this version. The camera system is better than most overall, although its 12 MP resolution is lower than most; it also has optical image stabilization and an ultrawide camera. Battery capacity is lower than most, but 15 W wireless charging is among the best. Wired charging is 25 W, and reverse wireless charging is supported. The phone offers 5G, NFC, Dual SIM and eSIM. Storage is not expandable, and the phone is sold with either 128 GB or 256 GB. The verdict is positive for anyone who prioritizes a high-end display, low weight and wireless charging: its NeoScore is 7.0.
