Galaxy S10 Plus vs Galaxy S21 5G


Swappasaurus says...

An upgrade from the Galaxy S10 Plus to the Galaxy S21 means going from the plus-sized model to the regular-sized model. This means you will be getting a slightly smaller display, going from 6.4-inches on the S10 Plus to 6.2-inches on the S21. The display may shrink a little with this upgrade path, but you will be getting a newer processor which brings an overall performance boost. The Snapdragon 855 powers the S10 Plus, and the Snapdragon 888 processor powers the Galaxy S21. You also get a boost in network connectivity due to the 5G support found on the Galaxy S21. Other key features of the Galaxy S21 include a 4800 mAh battery, 8GB of RAM, up to 256GB of internal storage, and a 10MP (f/2.2 aperture) selfie camera on the front.
