Samsung’s Galaxy Note10+ was the company’s first device to enable 45W wired charging in 2019; since then, it hasn’t advanced one millimeter. In Samsung’s lineup, 45W is still rather uncommon. The introduction of stacked batteries, a technology adapted from EVs, could signal the beginning of a revolution in the status quo.
The stacked battery will be present in the Galaxy S24 Ultra and potentially the S24+, according to @RGCloudS. Depending on the supply chain, Samsung is now only conducting testing using batteries produced at a Chinese facility because the Cheonan factory is still awaiting the arrival of manufacturing equipment.
Faster charging is one benefit of stacking batteries; the S24 Ultra can charge at up to 65W (up from 45W for the 2023 model). According to reports, the S24 Ultra and S24+ batteries both feature 5,000mAh capacities, but the Ultra will supposedly include additional cooling, enabling it to charge at a faster rate.
The little Galaxy S24 might not be able to be upgraded as well; it might remain at 25W for yet another year. However, after the stacked battery technology has proven itself (and supply restrictions have been removed), it may also be employed in next Galaxy Z Flip6 and Z Fold6 models. By the way, all iPhone 15 models are anticipated to feature stacked batteries from Apple.
