A report from Korean-language website FNNews claims that Samsung is considering a move to silicon-carbon batteries for its next-generation Galaxy phones, which could see battery capacities leap from 4,000mAh and 5,000mAh to 6,000mAh and 7,000mAh.

Samsung is said to be adding battery-extending technology to the Galaxy S26 smartphone range, though it should arguably have been present in the Galaxy S25 already. South Korean outlet Fnnews has issued a fresh report claiming that Samsung is pondering the use of silicon-carbon (Si-C) battery technology in next year’s Galaxy S26 family.

More evidence of the Samsung Galaxy S26 getting a major battery upgrade has surfaced, which may make anyone considering picking up a new Galaxy S25 to wait for next year's model.
