For the Galaxy S26, Samsung could revolutionize the battery of its smartphones
The Samsung Galaxy S25s are about to be presented by Samsunghere for just a few daysduring a Galaxy Unpacked which no longer really has any secrets: for months, even years, leaks of all kinds have allowed us to get a good idea of the technical characteristics, the design or even some of the functionalities planned by the South Korean giant for its new range of premium smartphones. And while the S25s have still not been officially presented, we are already starting to talk about the range that will arrive next year: the Galaxy S26.
Silicon-carbon batteries?
A recognized leaker, Jukanlosreverelays a rumor (which he attributes to another leaker: Ice Universe) on X, claiming that Samsung plans to use a silicon-carbon battery in the Galaxy S26. This could represent a major breakthrough, which does not happen alone: yesterday, Thursday January 16, the Korean publication The Elec was able to announce that Samsung was showing particular interest in innovative battery design techniques, by increasing their capacity thanks to to stacked electrodes. This is a solution already used by various firms dedicated to the construction of batteries for electric vehicles in particular.
For the moment, it is impossible to determine whether Samsung intends to combine silicon-carbon technology and stacked electrode construction, but one thing is certain: the firm is currently working to enable the use of much smaller batteries that would not lose in overall autonomy. These rumors are all the more interesting since the latest rumors reporta particularly disappointing autonomy for its next thin model : the Samsung Galaxy S25 Slim, which should be revealed very soon. Such technology could in fact make it possible to overcome these finesse defects without having to deal with the usual disadvantages.
