Samsung released its Galaxy S25 series earlier this year to generally favorable reviews. It also teased the perplexingly thin S25 Edge, and now that phone is a reality. You can preorder Samsung's thinnest smartphone-ever today, but you should know what you're getting into. This $1,099 smartphone is incredibly slim, at just 5.8 mm, but it also steps down in the camera department and packs an anemic battery that may struggle to last all day.

This is a big, flat phone featuring a 120 Hz 6.7-inch OLED at 1440×3120. Like the S25 Ultra, it has a titanium frame with Gorilla Glass Victus 2 on the back. The front has Gorilla Glass Ceramic 2 for improved scratch protection. There's almost no bezel around the display—in fact, there's almost no phone around the display. The body is only 5.8 mm thick, a substantial reduction from the similarly sized S25+ at 7.3 mm. That's really this phone's claim to fame: It's really thin. Everything else (and we do mean everything) is secondary to that.

Cramming premium camera modules into a smartphone is an engineering challenge even when you're not trying to make the phone as slim as possible. Similar to foldables, there just isn't enough space in the S25 Edge for a full suite of Samsung cameras. Therefore, this phone only has two rear camera modules: a 200 MP primary shooter that appears identical to the S25 Ultra's and a meager 12 MP ultrawide. There's a 12 MP selfie camera on the front as well. There is no telephoto lens at all, which you get even on the base model S25.

While the body of the phone is just 5.8 mm thick, the camera modules stick out a few millimeters more, making the phone quite wobbly when you set it on a table. The cameras have to stick out to leave more space for the internals, which are pretty powerful. Inside, this phone is essentially unchanged from the other S25 phones, with a Snapdragon 8 Elite, 12GB of RAM, and either 256 or 512GB of storage. The battery will be a problem, though.

It is very, very thin.

While the S25+ sports a passable 4,900 mAh cell, the super-slim S25 Edge has just 3,900 mAh of juice. That is a problem because the Snapdragon 8 Elite is a flagship processor designed for speed. While it's relatively efficient in low-power mode, it will devour the Edge's battery in short order if you're playing games or multitasking. A 20 percent reduction in battery life compared to the Galaxy S25+, which is a one-day phone, is a tough sell.

Most smartphone manufacturers could never justify making such a strange, niche device. This is Samsung showing off its engineering skills, and the S25 Edge does look neat. But the novelty of a super-slim phone will probably wear off when you have to start plugging it in to get a boost mid-afternoon. It doesn't even charge very fast, topping out at a mere 25 W. And you'll be paying $1,099 for the privilege, which slots the Edge between the S25+ ($1,000) and the S25 Ultra ($1,300).

If you want a phone that is thin at the expense of everything else, you can order the Galaxy S25 Edge from Samsung or Best Buy. It comes in black, icy blue, and silver colors and will ship on May 30.
