Samsung could implement silicon-carbon batteries in its next-generation Galaxy S26 series. This means we can expect an increase in battery capacity.
In case you are not aware, silicon-carbon batteries offer a lot of improvements over conventional lithium-ion ones. In this technology, silicon is substituted for part of the graphite in a battery’s anode, which increases energy-storing capacity in equal volume. It implies that OEMs can now offer larger battery capacities without expanding the battery’s actual size.
According to a report from FNNews, the Galaxy S26 lineup might feature silicon-carbon batteries. While the exact figures are not revealed yet, the report suggests we could see a battery capacity of 6,000 mAh to 7,000 mAh.
Up until now, Samsung has been offering battery capacity in the range of 4,000 mAh to 5,000 mAh in its Galaxy S series phones. For instance, the current flagship, the Galaxy S25 Ultra, packs a 5,000 mAh battery, which is the same capacity as that of 2020’s Galaxy S20 Ultra battery.
The silicon-carbon batteries in smartphones are still in the early days. That said, Chinese smartphone manufacturers have started implementing this tech, which includes popular brands like Xiaomi, Vivo, iQOO, and OnePlus.
The Galaxy S26 series’s launch is still a year away, and eventually, it will go through several testing phases. The report further says that Samsung has encountered a lifespan issue with the new battery tech, so it is studying various improvement measures.
Throughout the process, Samsung might change its plan completely, so take this information with a grain of salt for now.
