Galaxy S25 Edge doesn’t get a silicon-carbon battery
By ForGeeks The company has eschewed third-party suppliers in favor of in-house production.
The Samsung Galaxy S25 Edge smartphone, recently introduced in the S25 lineup, features a battery with a capacity of 3900 mAh manufactured exclusively by Samsung SDI. This was reported by TheElec citing internal sources in the supply chain.
Unlike the other models in the series – Galaxy S25, S25+ and S25 Ultra – which used batteries from two suppliers (Samsung SDI and China’s ATL), in the case of the Galaxy S25 Edge, Samsung has decided to use only one source. Previously, the company also purchased batteries from BYD and LG Energy, but in this model it relied on in-house production.
The decision likely stems from a desire to control battery reliability, quality and safety, especially in a device with a thin body. At the same time, the Galaxy S25 Edge did not get a battery based on a silicon-carbon anode -a technology that Chinese manufacturers have begun to adopt. Such cells provide 10-15% more capacity 10-15% more for the same volume.
Samsung, according to TheElec, is betting on the development of its own SUS CAN technology. It should provide higher energy density and solve the problem of bloated batteries previously seen in the company’s devices. The first smartphones with such batteries are expected in the Galaxy S26 series in early 2026, as well as future flexible models that will be released in the second half of next year.
