Galaxy S21 vs S20: What’s Different?


Both devices – Galaxy S21 and S20 – features a 6.2 inches display for users’ viewing pleasure. However, there’s a slight, almost unnoticeable difference in the aspect. While the S20 device came with a 3,200 x 1,440 display resolution, it was watered down to 2,400 x 1,080 in the Galaxy S21 device. To be fair, a 2,400 x 1,080 display resolution is very decent and users might not even tell the difference.


Galaxy S21

An impressive 8GB RAM is available on the Galaxy S21 device. However, this isn’t as impressive as the 12GB RAM that ships with the predecessor. So, imagine how impressive your S20 performs right now, do you really want to “upgrade” to the S21? I should note that this shouldn’t be a really big deal if you’re a light smartphone user – 8GB RAM is decent for the average smartphone user.

Internal Storage

The S20 device comes with 128GB of internal storage for your files and docs. This can be expanded up to 1TB with the use of a microSD card. The Galaxy S21 is available in two variants—128GB and 256GB. It cannot be expanded with an external SD card.

Dimensions and Weight

Well, as the manufacturers attempt various designs and models, this is bound to change. The Galaxy S21 is slightly heavier and has higher dimensions than the S20. While the S21 weighs 171g and measures 71.2 x 151.7 x 7.9mm, the S20 weighs 163g and measures 69.1×151.7×7.9mm.

There’s also a drop in this aspect, which is a reflection of the watered-down specs. The S21 device currently retails for $799 while the S20 retailed for $999 when it launched.

Should You Upgrade to the S21 Device?

From the differences in specifications covered above, the S20 is obviously superior to the S21. Hence, ditching the S20 device for the S21 doesn’t seem like the best move. But again, if you prefer to use the latest devices regardless of specs, by all means, go for the Galaxy S21.
