Samsung SDI is reportedly testing a massive dual-cell silicon-carbon (Si/C) battery with a combined capacity of 20,000mAh, signaling early efforts to dramatically increase battery sizes for future smartphones and portable devices. However, the technology is not yet ready for mass deployment at Samsung. As a result, Samsung is expected to continue using conventional lithium-ion batteries for its near-term flagship devices, including the upcoming Galaxy S26 Ultra, which is still rumored to retain a battery capacity of around 5,000mAh. While the test underscores Samsung SDI’s long-term ambitions in next-generation battery technology, significant engineering hurdles remain before such high-capacity silicon-carbon batteries can safely reach consumer smartphones. Samsung has opened pre-orders in the Philippines for its new Magnet Wireless Battery Pack, a handy accessory made for the Samsung Galaxy S26 series and other Qi2-ready devices.
