CNET gave the base Galaxy S20 a rating of 8.7 out of 10, naming it the best out of the S20 line. Our reviewer appreciated top-shelf features such as a sharp display and advanced camera capabilities, but noted that the starting price of $1,000 (£799, AU$1,349) was a bit high for what you get. While the S21 is mostly similar in features, unless S20’s price drops more (you can get it refurbished for around $550), it seems worth it to upgrade to the S21. Read our full Galaxy S20 review.
Design, screen size and weight
The Galaxy S21 and Galaxy S20 are extremely similar when it comes to displays. Both feature 6.2-inch Dynamic AMOLED screens, a 120Hz refresh rate and an in-screen fingerprint sensor.

The two phones also appear to be close to identical in design. The only major difference in appearance is the rear camera module — on the S21, it has a metal overlay. Both phones are IP68-rated for water and dust resistance..
In terms of colors, the Galaxy S21 comes in pastels called phantom violet, phantom gray, phantom pink and phantom white (other colors are available for the S21 Plus and Ultra models). The Galaxy S20 is available in cosmic gray, cloud blue, cloud pink and cosmic black.
The base model Galaxy S20 and Galaxy S21 have the exact same camera setup: The rear camera modules have a 64-megapixel telephoto camera, a 12-megapixel wide-angle camera and 12-megapixel ultrawide camera. Both phones also come with a 10-megapixel selfie camera. The cameras are the same on both Plus models, too.
The major camera upgrades come with the S21 Ultra. This model has four rear cameras: a main 108-megapixel wide sensor and a 12-megapixel ultrawide camera, plus two 10-megapixel telephoto lenses — one with 3x zoom and one with 10x zoom. It also boasts a fast Bright Night sensor and, which makes your photos more detailed.

Two of the biggest upgrades to the S21 are the phone’s processor and the software it runs — it’s now on Android 11 with a, which should lead to increases in speed and performance. The S20 was originally released with Android 10 and has a Snapdragon 875.
Winner: Galaxy S21
The base Galaxy S20 and S21 models have the same battery size of 4,000 mAh. The battery size rises to 5,000 mAh in both the S20 Ultra and S21 Ultra.

Winner: Tie (except in the case of the S21 Plus, which wins over the S20 Plus)
All S21 and S20 models support 5G connectivity, so again, no difference there.
One of the bigger differences between the two phone models comes at the Ultra level. The Galaxy S21 Ultra includes(sold separately for $40), whereas none of the S20 models do. That means S21 Ultra owners will soon be able to use the small digital pen to jot notes, take better screenshots, sign documents or draw in their favorite apps.
Outside of the processor, perhaps the biggest difference between the base S20 and S21 is the price tag. The Galaxy S21 is now on sale (), starting at $800 for the 128GB model. In comparison, the Galaxy S20 started at $1,000. Though the price on the S20 has fluctuated since the Galaxy Unpacked event, Samsung didn’t say whether it would get a further decrease, and thus far it doesn’t seem to have done so. For international pricing see the chart below.
