Galaxy S9 Plus vs Galaxy S21 5G

Going from a Galaxy S9 Plus to a Galaxy S21 means skipping several generations, and going from a model that was released in early 2018 to a model that was released in early 2021. This upgrade path will not only give you a big boost in performance but will also give you a boost in terms of display quality and overall looks. The display goes from a 6.2-inch (2960 x 1440) Super AMOLED on the S9 Plus to a 6.2-inch (2400 x 1080) Dynamic AMOLED 2x Infinity-O on the S21. The Infinity-O aspect also speaks to the improved looks, which come courtesy of the slimmer bezels. The Galaxy S21 is powered by an 8-Core Qualcomm Snapdragon 888 processor, which is compared to the Snapdragon 845 in the S9 Plus. Other highlight features of the S21 include 8GB of RAM, up to 256GB of internal storage, an IP68 rating for water and dust resistance, and a 4000 mAh battery that supports 15W fast wireless charging and 25W fast wired charging.
