New Samsung Galaxy S21 Features & Functions

When comparing the new Samsung Galaxy S21 to its predecessor the S20, they share most of the same features, but there are some upgrades to enjoy on Galaxy S21 specs. The basic S21 and S20 share the same design, camera, durability, and battery life. The biggest differences in the basic S21 is in processing speed; the S21 is now on Android 11 with a Snapdragon 888 processor. This should lead to increases in speed and performance in the Galaxy S21 series. The S21 is also slightly heavier than earlier models.

The majority of the upgrades in the S21 line, however, come from the Galaxy S21 Ultra model. The S21 Ultra comes with four rear cameras, a main 108 megapixel wide sensor, a 12 megapixel ultrawide camera, two 10 megapixel telephoto lenses (one with 3x zoom and the other with 10x zoom). It also has special technology for night photos and pixel binning technology to make your photos clearer. Battery life is another improvement in the S21 Ultra, with 4,800 mAh that should last you the whole day. The Galaxy S21 Ultra also offers S Pen stylus support, which can be used as a digital pen to take notes, easily sign documents, draw or take better screenshots.
