Samsung might be testing a monster battery while its phones keep using small ones. Leaks suggest Samsung SDI is working on a dual-cell silicon-carbon battery with a total capacity of twenty thousand milliamp hours, a huge jump aimed at catching Chinese rivals using similar tech. This experimental design reportedly has a primary twelve thousand milliamp hour cell and a secondary eight thousand milliamp hour cell, but it's still unstable, with one cell swelling by eighty percent in tests.

Silicon-carbon batteries use a special anode that can hold way more lithium ions than standard graphite, allowing for much higher capacity in a thinner package. This tech explains how some affordable phones already ship with batteries nearing ten thousand milliamp hours. Samsung's flagship Galaxy S phones, like the upcoming S26 Ultra, still stick to around five thousand milliamp hours, drawing criticism for not keeping up.

The new battery is clearly not ready for market, given the severe swelling issue, meaning a launch is not happening soon. For now, Samsung will keep taking heat for its conservative battery sizes while it tries to solve the technical hurdles behind the scenes with its advanced, but problematic, prototype.
