The Samsung Galaxy S25 Slim is one of the thinnest phones ever created by Samsung, with a thickness of just 6.4 mm. This ultra-slim design showcases a technological advancement that prioritizes lightness and elegance while maintaining powerful features. This new addition to the Galaxy S25 series promises an exceptional user experience with its bold design and innovative features.
Galaxy S25 Slim: Ultra-Slim Design
At just 6.4 mm thick, the Galaxy S25 Slim pushes the limits of smartphone design. When the camera module is included, the total thickness doesn’t exceed 8.3 mm. Compared to other phones that are easily 8 to 10 mm thick without the camera module, this figure is remarkable.
The approximate dimensions of the Galaxy S25 Slim are 159 x 76 x 6.4 mm, making it thinner and more compact than the Galaxy S25 Ultra, which measures 162.8 x 77.6 x 8.2 mm. This size difference clearly shows a significant advancement in slimness without compromising performance.

Samsung Galaxy S25 Slim: Screen and Camera
The Galaxy S25 Slim features a flat screen measuring about 6.7 to 6.8 inches diagonally. This model also has an extremely thin bezel design, just like the entire S25 series. On the back, there’s a triple-camera setup, including a 200 MP main sensor, a 50 MP ultra-wide lens, and a 50 MP telephoto lens with 3.5x optical zoom.
Samsung uses an innovative ALoP (All Lenses on Prism) design for the 3.5x telephoto lens, positioning the lenses in front of the prism to maintain the slim design while offering advanced optical zoom.

Powerful Performance Under the Hood
Under the hood, the Galaxy S25 Slim is powered by the Snapdragon 8 Elite chipset, paired with 12 GB of RAM. It runs on Android 15 with One UI 7, providing a smooth and intuitive user experience. According to Geekbench leaks, the S25 Slim achieves impressive scores of 3005 in single-core and 6945 in multi-core, reflecting powerful performance for demanding users.
Compared to older models like the Galaxy A8, which was the thinnest at 4.9 mm but had a much smaller battery (3050 mAh), the Galaxy S25 Slim offers a much larger battery while maintaining a remarkable slimness. This allows for extended usage without compromising thickness.
Expected Launch Date: May 2025
The Samsung Galaxy S25 Slim is expected to launch in May 2025. While it will likely be showcased at the Unpacked event on January 22 alongside the Galaxy S25, S25+, and S25 Ultra, the actual release is scheduled for later in the year.
With ultra-slim smartphones becoming increasingly popular, the Galaxy S25 Slim positions itself as a premium option, offering an innovative design without sacrificing performance.
