Reports have been pouring in about the Samsung Galaxy S24 from various sources. Recently, rumors suggested that the Galaxy S24 Ultra might feature a faster GPU than the iPhone 15, but with fewer cameras. The latest report indicates that Samsung is incorporating car tech to improve battery life in the Galaxy S24 Ultra.

Samsung SDI, the department responsible for developing and manufacturing Li-Ion batteries, may plan to integrate a capacity increase technology used in their electric car cells into Galaxy smartphones and tablets. This technology, known as ‘stacking,’ involves tightly stacking battery components such as cathodes and anodes to improve energy density.

The Elec’s report suggests that stacking battery components will enable Galaxy phones to have a higher battery capacity. Samsung could add 10% more capacity to the Galaxy S23 Ultra’s 5,000 mAh battery using this technology. The report alleges that this battery technology could be implemented soon, starting with the release of the Galaxy S24 Ultra next year.

Samsung SDI, the South Korean battery giant, is reportedly planning to apply the stacking method to their batteries to compete with LG Energy, their rival who already uses this technology. Two Korean companies were expected to collaborate with Samsung, but instead, Samsung has entered into a joint venture with two Chinese rivals. Samsung SDI will develop the required equipment for stacking at their plant in Cheonan, South Korea, and the Chinese companies are setting up offices in South Korea for better communication. One of the partners, Shenzhen Yinghe Tech, has already provided the stacking equipment to Samsung SDI after a pilot line test in a factory in Tianjin.
