Samsung is looking into silicon-carbon batteries for future phones, perhaps meaning a big upgrade for the Galaxy S26 series next year.

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.

Samsung is reportedly considering a shift to next-gen silicon carbide batteries, and might ship units as large as 7,000 mAh capacity on the Galaxy S26 series.
