Samsung’s Galaxy S25 Edge is its slimmest phone to date, showcasing impressive engineering in a sleek design. A recent teardown of the device provides insights into how Samsung successfully integrated advanced technology into this thinner and lighter smartphone.

Last month, the company shared a blog post explaining their innovative design process, highlighting how they achieved what they call a “beyond slim” structure. One of the key advancements contributing to the Galaxy S25 Edge’s thin profile is a new mounting method that allows precise component placement within 0.1mm.

While Samsung likely streamlined several components, the details of how these elements were compacted can be better understood through a teardown analysis. YouTube’s Zack Nelson, known as JerryRigEverything, conducted a teardown that illuminates the modifications made in the Galaxy S25 Edge.

While the internal layout appears similar to that of the Galaxy S25 Ultra, there are distinct changes. For instance, a thinner vibrator motor was employed for the loudspeaker, marking a shift toward a more compact design.

Although this change alone may not account for the overall slimness, it sets a precedent for Samsung’s effort. Another notable adjustment is the decision to eliminate a standalone housing for the connector pins of the 25W USB-C port.

Instead, Samsung opted to have the Titanium frame serve as the housing, effectively saving space. This minor modification, along with others, contributes to the overall reduction in size.

Additionally, Samsung removed a section of the aluminum frame situated between the vapor chamber and the processors, which helped achieve the impressive 5.8mm thickness. While this teardown does not provide a comprehensive breakdown of every aspect of the design process, it offers a fascinating glimpse into the engineering strategies that led to the Galaxy S25 Edge’s minimalist profile.
