Samsung is reportedly developing batteries with stacked technology, which could enable its future Galaxy flagships, like the S26 Ultra, to offer a 5,500mAh battery without increasing size. This approach aims to achieve around 10% higher energy density compared to traditional Li-ion batteries.
The tech, developed by Samsung SDI, would allow for larger battery capacities in flagship devices without making them bulkier. Chinese phone manufacturers have already adopted this technology with silicon carbide (SiC) batteries, which offer a similar increase in energy density and no corresponding increase in thickness.
However, it’s worth noting that rumors about Samsung working on stacked batteries have been circulating for years but have yet to materialize. This new development marks a significant advancement in battery technology for the company.
In contrast, Apple has been using stacked batteries in its iPhones since the iPhone 15 series. While this technology is not new, its adoption by other manufacturers like Samsung is significant.
Battery life, however, is not solely determined by battery capacity. Processor optimizations, heat management, and software also play crucial roles in maintaining device performance throughout the day. The Galaxy S24 Ultra demonstrated impressive battery life in our tests, outlasting some of its competitors.
With this new development, Samsung may finally address the criticism surrounding its flagship devices’ battery life. However, it’s unclear whether this technology will be reserved for flagships only, given the high manufacturing costs associated with stacked batteries.
