The annual Galaxy S update at Samsung’s Unpacked event brought us three new phones in the series.

Design, display, and durability
- 2. Galaxy S10
While there’s no mistaking that these phones belong to the same family, Samsung has made a few design tweaks to the S20. It’s still a curved glass sandwich, but the camera module on the back is now vertically stacked and shifted off to the top left. The headphone port is gone from the S20 and so is the Bixby key.
Samsung has managed to squeeze in a tiny bit more screen without increasing the overall size by much — an impressive feat given the expanded battery and 5G support. The hole-punch camera that was top right on the S10 has been centered on the S20. The Dynamic AMOLED screen on the S20 improves on its predecessor’s already excellent display with a much higher 120Hz refresh rate that lends a silky smooth feel to scrolls and swipes and ensures that even the most demanding of games look as they should.
Dropping either of these phones is liable to cause severe anxiety, so cases are advisable, but they do have an IP68 rating, which means they can survive submersion in fresh water for up to half an hour.
Winner: Samsung Galaxy S20
Performance, battery life, and charging
The Samsung Galaxy S20 has the Qualcomm Snapdragon 865 processor inside, or the Samsung Exynos 990 in some markets, and a whopping 12GB of RAM. The S10 has last year’s Snapdragon 855 and 8GB of RAM. While there’s no doubt that the S20 is faster and more capable in the multitasking department, the S10 will still be plenty powerful for most people. The higher refresh rate in the S20 will also make it feel more responsive, but both these phones can run the most demanding games and apps, and that’s likely to be true for some time to come.
Samsung has somehow managed to pack in a much bigger battery for the S20, adding an extra 600mAh. It will need some of that to handle the higher power demands of 5G, the extra RAM, and the larger screen with its higher refresh rate, but it should still outlast the S10. The S20 is also capable of faster wired charging at up to 25W. Both phones can be charged wirelessly.

Cameras
Although the S20 has a triple-lens main camera, just like the S10, Samsung has made some improvements, including upgrading the telephoto lens from 12 megapixels to 64 megapixels, which enables a 3x optical zoom and 30x digital zoom. The ultrawide lens has dropped from 16 to 12 megapixels, but thanks to the larger image sensor, the S20 can capture more light, so it should turn out better photos than the S10 in low-light environments. Samsung also promises that improvements have been made to the artificial intelligence to make it easier to find the ideal settings to capture the best photos in different situations. The S20 is also capable of 8K video recording, while the S10 maxes out at 4K. Both have a 10-megapixel front-facing camera.
Winner: Samsung Galaxy S20
Software and updates
The Galaxy S20 runs Android 10 with Samsung’s streamlined One UI 2.0 over the top. This software combination has already been rolled out to the Galaxy S10, so there’s very little discernible difference between these two phones on the software front. The S20 may get updates a little quicker and for a little longer than the S10, but as it stands, there’s no dividing them here.
Winner: Tie
Special features
The big new feature in the S20, beyond what we’ve already looked at, is support for 5G. However, the Galaxy S20 can only support Sub-6 5G networks and can’t handle the higher frequency mmWave technology — you’ll need to jump to the S20 Plus or S20 Ultra for that. In simple terms, Sub-6 has a better range and penetration than mmWave, but doesn’t offer such fast speeds. The Galaxy S10 is limited to 4G connectivity. If you live in a city or you want to future-proof for 5G, then the S20 is going to be a better pick for you, but we advise checking in with your carrier on coverage and available plans before you decide.
Winner: Samsung Galaxy S20
Price and availability
The Samsung Galaxy S10 is currently widely available starting from $700.
The Samsung Galaxy S20 starts from $1,000. You can pre-order the Samsung Galaxy S20 from February 21, and if you do so before March 5, you’ll get a $100 Samsung credit.
Overall winner: Samsung Galaxy S20
As you would expect, the Galaxy S20 comes out victorious with a faster processor, more RAM, an improved display, a better camera, and a bigger battery. All of that comes before we mention 5G connectivity. Although there are tangible improvements across the board here, they’re mostly incremental. The S10 is still an excellent phone, especially if you’re not in a position to take advantage of 5G yet, and it can be had for several hundred dollars less than the S20.
