Samsung to equip Galaxy S26 with silicon-carbon batteries

Samsung is considering enhancing the battery capacity of the Galaxy S26 by altering the battery technology. FNNews suggested that the Korean company may adopt a Silicon-Carbon solution, potentially enabling the phones to achieve a capacity of up to 7,000 mAh.

The new battery technology replaces graphite with silicon in the cathode material, enhancing capacity. Initially, these batteries had higher production costs and insufficient yields, however, with brands like Xiaomi, vivo, and OnePlus launching flagships featuring this tech, Samsung is finally ready to hop on board.

Samsung’s cautious stance on silicon-carbon batteries stems from its production of "far more units" than its Chinese rivals. This reasoning also applies to the 25W and 45W charging rates that the Korean firm has consistently employed over the years.

Samsung is heavily investing in the integration of Si/C batteries in its flagship models for next year, according to FNNews. Issues related to material composition and expansion have been addressed, potentially boosting Apple’s confidence in adopting these thinner batteries for the iPhone 17.

The Samsung Galaxy S25 Ultra was released featuring a 5,000 mAh battery and 45W charging, the very same battery found in the five-year-old Galaxy S20 Ultra. Similarly, the vanilla Galaxy S25 is equipped with a 4,000 mAh battery and supports 25W charging, just like its 2020 sibling.

Only the Galaxy S25+ has been getting incremental upgrades in the battery department, despite the Plus being the least desirable variant in the flagship trio.
