According to a reliable source called RcloudS, it seems that the next versions of Samsung’s smartphones, the Galaxy S24 Ultra and Galaxy S24+, could have a significant improvement in their fast charging capabilities. Currently, these devices support fast charging up to 45W, but the tipster suggests that this could increase by 45% to 65W.
This enhancement would be achieved by using stacked batteries, a new technology that improves performance and charging speed. To manage the potential increase in heat generated by stacked batteries, Samsung plans to incorporate a cooling gel.
Stacked batteries are considered safer than single Lithium-ion batteries, despite the fact that they may get hotter due to lower heat dissipation. Samsung is currently testing these batteries in prototype models, but the necessary equipment to implement them has not yet arrived at the company’s Cheonan factory.
However, there might be a limitation in the availability of stacked batteries, and as a result, the base model of the Galaxy S24 series may not be equipped with them. Consequently, the lower-end variant would still offer fast charging speeds of up to 25W, while the higher-end models, the Galaxy S24 Ultra and Galaxy S24+, would provide the improved 65W fast charging. In the future, Samsung may also consider implementing stacked batteries in other models such as the Galaxy Z Fold 6 and the Galaxy Z Flip 6.
Interestingly, it appears that Apple is also planning to adopt stacked batteries for their upcoming iPhone 15 lineup. This suggests that stacked batteries could become a trend in the mobile industry, offering users faster charging speeds and enhanced performance.
