vs

Upgrading from the Galaxy S9 to the Galaxy S21 means you would have skipped a few generations, and that means you will experience a big boost in overall performance. A big reason for the performance is due to the processor, which is an 8-Core Qualcomm Snapdragon 888 in the Galaxy S21. The S21 also brings support for 5G networks, as well as more RAM, more internal storage, and a bigger battery with faster charging. The Galaxy S21 has 8GB of RAM, supports up to 256GB of internal storage, and has a 4000 mAh battery. The battery allows for fast wired charging up to 25W and fast wireless charging up to 15W. It also allows for 4.5W of reverse wireless charging which means you can charge other devices using your Galaxy S21. The front and rear camera setups were also improved with the S21 featuring a 10MP selfie camera on the front with a 12MP wide, 12MP ultrawide, and 64MP telephoto on the back.
