Galaxy S9 Plus vs Galaxy S21 Ultra 5G

Swappasaurus says...
Upgrading from a Galaxy S9 Plus to a Galaxy S21 Ultra means skipping several generations, and also going from a plus-sized model to an ultra-sized model. Going from the Plus to Ultra means you will be getting a bigger display, which in this case has you going from 6.2-inches on the S9 Plus to 6.8-inches on the S21 Ultra. The S21 Ultra display has a resolution of 3200 x 1440 and supports a refresh rate of up to 120Hz. Other areas of improvement include more RAM, more internal storage, a bigger battery, a better camera setup, and 5G connectivity. The Galaxy S21 Ultra offers up to 12GB of RAM, up to 512GB of internal storage, a 5000 mAh battery with fast wired charging and fast wireless charging, a 40MP front-facing camera, and a 108MP wide, 12MP ultrawide, 10MP telephoto, and a 10MP periscope zoom setup on the back.
