Design: Feel in the Hand
Both phones look and feel like flagships. You get a tough metal frame and Gorilla Glass, big size, and that squared-off look Samsung Ultra users know so well. Set them side by side and you’ll notice the S25 Ultra is just a bit slimmer and lighter. For pockets, it’s not a huge difference, but your hand will thank you after a long day.
The S23 Ultra comes in bright and classic colors, while the S25 Ultra’s new titanium shades are a little more refined and a touch more businesslike. Both keep the handy S Pen, tucked in at the bottom corner, which is still great for notes or a quick doodle when you need it.
Displays
The displays on these phones are huge and hard to fault. Both use Samsung’s sharp AMOLED tech with a silky-smooth 120Hz refresh. The big win, though, goes to the S25 Ultra for brightness.

But Samsung couldn’t leave it there. The S25 Ultra upgrades to the Gen 3 version with snappier memory.
