Samsung might opt for a silicon-carbon (Si/C) battery within its next-gen flagships, including the Galaxy S27 Ultra. Even so, the South Korean tech behemoth is apparently playing it very safe and refusing to go wild with 10,000mAh-like battery capacities for its Galaxy S27 series. While this tidbit might disappoint some, given the fact that 6,000mAh+ battery capacities are increasingly becoming the norm with Chinese smartphones, we contend that the rumored 5,800mAh battery for the Galaxy S27 Ultra will be more than enough, courtesy of two key innovations.

Samsung refused to jump onto the silicon-carbon (Si/C) battery bandwagon until the technology was truly ready for mass adoption, taking a morally upright stand that cost it dearly, especially in China, where local players have been happy to run with battery capacities as high as 10,000mAh. Now, however, one tipster believes Samsung has cracked the silicon-carbon battery longevity code, and that the Galaxy S27 will "most likely" ship with such a battery, replete with a much higher capacity than the 5,000mAh level that seems to have become a norm for the South Korean tech giant lately. Samsung is going all […]

Samsung has remained very conservative in its experimentation in the smartphone battery department ever since the Note 7 fiasco back in 2016. However, this reluctance is now costing the South Korean behemoth dearly as Chinese OEMs increasingly take the initiative with monster silicon-carbon (Si/C) batteries. Against this relatively challenging backdrop, we reported towards the end of 2025 that Samsung had commenced and then abandoned its testing of a mammoth 20,000mAh silicon-carbon battery. Well, now we know a lot more about those failed tests as well as Samsung's ongoing testing of a smaller 18,000mAh battery, courtesy of a few leaked documents. Samsung's […]

For the past six years, Samsung has retained the battery capacity of its Galaxy S lineup at 5,000mAh, meaning that users would only experience minor increments in runtimes regardless of which company flagship they purchased. Fortunately, this practice could be a thing of the past, as a rumor claims that the Korean giant is finally jumping onto the silicon-carbon bandwagon like a multitude of Chinese smartphone makers. As for why silicon-carbon batteries didn’t debut with the Galaxy S26 series, Samsung’s executive says these cells have to pass ‘very rigorous validation standards.’ The advantages of silicon-carbon technology are apparent, which is […]
