Let’s explore the information available regarding the thickness of the Samsung Galaxy S25, S25 Plus and S25 Ultra, and examine its implications on the design, performance, and user experience.
As we eagerly anticipate the arrival of Samsung’s next-generation flagship smartphones, the Samsung Galaxy S25 and Galaxy S25 Ultra, leaks and rumours are swirling about the features, design, and specifications of these highly anticipated devices. One key detail that has piqued the interest of tech enthusiasts is the thickness of the new models. Thickness may seem like a minor detail, but it plays a crucial role in the overall ergonomics, aesthetics, and functionality of a smartphone.
1. Samsung Galaxy S25 & S25 Plus
According to recent leaks, the Samsung Galaxy S25 and Galaxy S25 Plus are expected to be slightly slimmer than their predecessors, the Galaxy S24. Early reports suggest that the Galaxy S25 and Galaxy S25 Plus will have a thickness of around 7.2mm, a reduction compared to the 8.2mm thickness of the Galaxy S24. This slimmer profile aligns with Samsung’s trend of refining its flagship devices, making them sleeker and more comfortable to hold.
Impact on Design and Aesthetics
The reduced thickness of the Galaxy S25 and S25 Plus will likely give it a more streamlined and modern look. Slimmer devices tend to be more visually appealing and easier to slip into pockets or bags, making them more portable. Additionally, the thinner design may result in lighter weight, which could improve the overall user experience, especially for those who use their phones for extended periods.

While a thinner phone is often associated with a premium feel, it also brings up concerns about durability and battery capacity. However, Samsung has a history of balancing slim designs with robust performance, and the Galaxy S25 is expected to continue this tradition.
Despite the thinner design, Samsung is focusing on maintaining excellent image quality, packing in advanced sensors and optics. This thinner module allows the phone to feel sleeker, reducing the prominent “camera bump 1.8 mm from the body” which can be cumbersome for some users.
2. Samsung Galaxy S25 Ultra
For those who prefer a more feature-packed smartphone, the Samsung Galaxy S25 Ultra is expected to be slightly thicker than the standard S25, likely around 8.9mm. This thickness is common for “Ultra” models, as they typically come with enhanced features such as a larger battery, more advanced camera systems, and superior display technology.
The Galaxy S25 Ultra, known for its powerful photography capabilities, is likely to have a thicker camera (S25 Ultra would be 2.4 mm thick from body) module to house its more advanced features. The Ultra’s camera system may include larger sensors and improved optical zoom, which require additional space. However, the thickness will be carefully managed to ensure the device remains ergonomic and easy to handle.

The Role of Thickness in Battery and Performance
One of the main reasons for the slightly thicker profile of the Galaxy S25 Ultra is the need to house a larger battery. The Ultra models are known for their extended battery life, often lasting longer than standard models due to the increased battery capacity. A thicker body allows for a bigger battery without compromising the phone’s overall durability or performance.
In addition to the battery, the Ultra model’s thickness will accommodate a more sophisticated cooling system. As flagship devices become more powerful, managing heat becomes critical, especially during intense tasks such as gaming, 5G connectivity, or multitasking. A thicker design provides more space for heat dissipation mechanisms, ensuring that the phone maintains optimal performance without overheating.
3. How Thickness Affects Ergonomics and User Experience
The thickness of a smartphone directly impacts how comfortable it feels in the hand and how easy it is to use one-handed. While many users prefer slim and lightweight devices for daily use, others appreciate the solid, substantial feel of slightly thicker phones like the Galaxy S25 Ultra.
Ergonomics of a Slimmer Galaxy S25 & Galaxy S25 Plus
The reduced thickness of the Galaxy S25 & Galaxy S25 Plus should improve its overall ergonomics. A thinner device is typically easier to grip, especially for users with smaller hands. Additionally, a slim design makes the phone more pocket-friendly, which is essential for users who prioritize portability. The Galaxy S25’s thinner profile may also appeal to those who prefer minimalist designs that do not feel bulky or cumbersome.
The Feel of the Galaxy S25 Ultra in Hand
On the other hand, the Galaxy S25 Ultra’s increased thickness may contribute to a more substantial feel, which some users prefer. Thicker devices often feel sturdier and more robust, making them ideal for those who prioritize durability. Furthermore, the increased thickness might allow Samsung to incorporate larger camera sensors and lenses, enhancing the Ultra’s already impressive photography capabilities.
While the Galaxy S25 Ultra may be slightly heavier and thicker than the standard model, it’s likely that Samsung will employ curved edges or tapered sides to ensure that the device remains comfortable to hold. This design choice helps mitigate any potential discomfort associated with thicker devices.
4. Pros & Cons of Slimmer Design
Although a thinner phone is often seen as more aesthetically pleasing, it can come with certain trade-offs. One of the primary concerns with ultra-thin devices is battery life. As manufacturers strive to make phones slimmer, they sometimes have to reduce the size of the battery, which can impact the device’s endurance.
However, Samsung is expected to use cutting-edge battery technology in the Galaxy S25 to minimize this trade-off. Advanced battery materials and more efficient power management systems could allow the S25 to maintain a long battery life despite its thinner profile.
Additionally, slim phones are often more prone to bending or damage, especially when placed in tight pockets or dropped. It’s essential for Samsung to strike the right balance between sleekness and structural integrity to ensure that the Galaxy S25 remains durable.
5. Conclusion
The thickness of the Samsung Galaxy S25, S25 Plus and S25 Ultra highlights the different approaches Samsung is taking with its standard and Ultra models. While the Galaxy S25 is focused on achieving a sleek and portable design, the Galaxy S25 Ultra emphasizes power, performance, and battery life, with a slightly thicker body to support its advanced features.
For users who prioritize aesthetics and portability, the slimmer Galaxy S25 and Galaxy S25 Plus will likely be the ideal choice. Its reduced thickness ensures a sleek, modern design without compromising too much on performance. On the other hand, for those who need a powerhouse device with top-tier camera capabilities, extended battery life, and enhanced performance, the slightly thicker Galaxy S25 Ultra will provide the perfect balance between power and usability.
As more details about the Galaxy S25 series emerge, it will be interesting to see how Samsung continues to innovate in the balance between design and functionality. Regardless of the thickness, both models are expected to deliver the premium experience that Samsung’s flagship phones are known for.
