Samsung Galaxy S21 128GB
As part of the Galaxy S series, Samsung Electronics has created, developed, marketed, and produced a number of Android-based smartphones with the name Samsung Galaxy S21. They all serve as the Samsung Galaxy S20 series' successors.
The Galaxy S21 series has four different models: the entry-level Galaxy S21, the plus Galaxy S21+, the camera-focused Galaxy S21 Ultra, and the mid-range Galaxy S21 FE. A display with a 120 Hz adaptive refresh rate, an enhanced camera system providing 8K video recording (76804320) for the first three models, and a super-resolution zoom of 30-100x for the extreme model are significant improvements over the previous generations in addition to better specifications.
Non-removable Li-Po batteries with capacities of 4000 mAh, 4,500 mAh, 4800 mAh, and 5000 mAh are found in the S21, S21 FE, S21+, and S21 Ultra, respectively.
 All four versions enable Qi inductive charging at up to 15W and cable charging over USB-C at up to 25W (using USB Power Delivery). The phones also contain the "Wireless PowerShare" feature, which allows them to charge other Qi-compatible devices at up to 4.5W from the S21's own battery.
