We’re likely to get a first look at Samsung’s Galaxy S21 phone line on Jan. 14, at the company’s Unpacked event (here’s how to watch the phone unveiling live). The latest version of Samsung’s flagship Galaxy phone follows the Galaxy S20 line, released in 2020. If you’re in the market for an upgrade, you may be wondering: What exactly are the differences between the two Galaxy phones? And is it worth it to spend a rumored $850 for an upgrade? 

Here’s everything you need to know about how the Galaxy S21 is rumored to compare with the Galaxy S20. (Psst… Here’s why now is the worst time to buy the Samsung Galaxy S20.)

Because the Galaxy S21 has not yet been publicly unveiled, we can only report on the rumors we’ve heard about its specs and features. However, an extensive leak, posted on Android Police in November, documents almost the entire spec sheet for all three phones in the line: the Galaxy S21, the Galaxy S21 Plus and the Galaxy S21 Ultra (read on for how the Galaxy S21 specs compare to those of the S20). Samsung didn’t comment on the leak.

Based on those leaks and others, we know that the S21 has many similar features to the S20, including size (6.2 inches), battery (4,000 mAh), camera features (including a 12-megapixel ultrawide lens), a 120Hz display and 5G connectivity. However, the S21 is also rumored to run on Android 11, as opposed to the S20’s Android 10, and will have a Snapdragon 888 processor. The other major difference will be in the price: While the Galaxy S20 started at $999, the Galaxy S21 is rumored to start at $850a major price decrease, likely due to sales drops that Samsung experienced during the pandemic

Galaxy S20

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 called out top-shelf features, including a sharp display and advanced camera skills, but noted that the starting price of $999 was a bit high for what you get. That price has since dropped to $800 at Amazon and Best Buy. But if the S21 includes many of the same features and a few more upgrades, going for the newer phone could be the better choice, depending on the final price of course.
