One drawback of Samsung devices compared to Chinese-made devices is its charging system which is not very fast. The Galaxy S23 Ultra for example only charges at a maximum output of 45W. A report from The Elec now says this issue may be resolved after Samsung SDI develops a new battery that can not only be charged faster but also has a larger capacity.
Through stacked battery technology, Samsung SDI's new battery capacity can be increased by up to 10%. It will also allow for faster charging. Samsung SDI already uses this technology in their car batteries but not in smart device batteries. The Galaxy Note 7 exploding battery incident in 2016 caused Samsung to be more careful to prevent the same incident from happening again.
The batteries used now are of the coiled type and one of the issues that exists is that they will bubble after a few years. More interesting in The Elec report is that Samsung SDI is working with two Chinese companies to produce these stacked batteries. Rumors about Samsung's stacked battery have been heard since the beginning of this year. It is most likely that it will be used on the Galaxy Z Fold5 and Z Flip5 series that will be launched on July 26.
