Samsung is once again pushing the limits in flagship smartphone design with its upcoming Galaxy S26 Edge, following the sleek lines of its predecessor, the Galaxy S25 Edge. This new model promises to bring not only a larger battery but also a sleeker profile, addressing some of the trade-offs associated with ultra-slim devices. Thanks to insights from industry insiders, we have exciting details about the innovations on the horizon for this popular smartphone series.
Will the Galaxy S26 Edge Transition to Silicon-Carbon Battery Technology?
Currently, the Galaxy S25 Edge boasts an impressive thickness of just 5.8mm. According to the prominent leakster @UniverseIce, the Galaxy S26 Edge is set to take this a step further with an even slimmer design. While exact dimensions remain undisclosed, we anticipate more details to emerge soon, especially concerning the device’s significantly larger battery.
Samsung’s engineering team is reportedly exploring new battery materials that enhance capacity without increasing thickness. However, it remains unconfirmed whether these developments will include a shift to silicon-carbon battery technology, which has become popular among many of Samsung’s competitors in the Chinese smartphone market. Silicon-carbon batteries offer superior capacity while maintaining a slim profile, ultimately leading to longer battery life.
Confirmed: The Galaxy S26 Edge will be thinner than the S25 Edge and have a larger battery thanks to new battery material technology.

Previously, Samsung was reported to be investigating silicon-carbon technology, but there have been no recent updates on its progress. When asked about the omission of this technology in the Galaxy S25 Edge, a company executive noted that advanced AI features enhance the efficiency of the current flagship. Nevertheless, they acknowledged the pursuit of other viable technologies to push the envelope further.
The Galaxy S25 Edge features a 3, 900mAh battery, which, coupled with its sleek design, limits the inclusion of multiple rear cameras—resulting in only two sensors rather than three. As we look forward to the Galaxy S26 Edge, the potential for additional rear cameras hinges on Samsung’s ability to innovate further, allowing for both enhanced battery capacity and additional features that can significantly improve user experience.
