  • Samsung is working on stacked battery tech that could enable longer-lasting batteries.
  • The tech will apparently improve energy density by over 10%.
  • The Korean brand will purportedly use this tech in phones, tablets, laptops, and more.

Samsung’s Galaxy S23 phones all have wildly different battery capacities, ranging from the small 3,900mAh battery in the Galaxy S23 to the 5,000mAh pack in the S23 Ultra. However, it looks like the company is preparing new tech that could deliver better battery life across the board.

Korean publication The Elec reports that Samsung SDI is working with two Chinese companies to develop equipment for creating stacked battery designs.
