The Galaxy S24 Ultra might become Samsung's first flagship phone to adopt 65W fast charging technology. To achieve this, the company is working on adapting the stacked design from EV (electric vehicle) batteries to work with mobile devices.
A new rumor says that Samsung is in the stages of prototyping stacked batteries for smartphones (via @RGcloudS). Previous reports said the company is gearing up to start production at its Cheonan plant in Seoul, but the latest rumor claims that manufacturing equipment required for producing stacked batteries has not yet arrived at the Cheonan plant.
The rumor also states that Samsung is running a pilot manufacturing run for stacked batteries in China. However, limited quantities might prevent the tech giant from applying the upgraded battery technology to the entire Galaxy S24 lineup.
Stacked batteries might be reserved for top of the line models
Stacked-type smartphone batteries bring several advantages, from higher density to better performance and improved charging. However, rumors say that Samsung might have to reserve this upgrade to its top-tier Galaxy S24 Ultra.
In the best-case scenario, Samsung might have enough stacked batteries in 2024 to power the Galaxy S24+ and the Galaxy S24 Ultra alike. Even then, Samsung will reportedly be hindered by limited supply and may have to restrict the base Galaxy S24 model from using this new technology.
It is possible that the base Galaxy S24 will stick to 25W charging, while the rest of the series, or at least the Galaxy S24 Ultra, will boast 65W charging speeds and higher capacities. Looking further into 2024, it's also possible that the Galaxy Z Flip 6 and Z Fold 6 will use stacked batteries.
For now, Samsung is preparing the Galaxy Z Fold 5 and Z Flip 5 for an unveiling at Galaxy Unpacked on July 26. The Galaxy S24 series will probably be announced early next year.
