Samsung's next phones will use a different kind of battery
Since the new flagship from the South Korean company has the same 5,000 mAh battery with 45W fast charging as its predecessor, the Galaxy S24 Ultra, we think the Samsung Galaxy S25 Ultra has stopped growing primarily because of its autonomy.
Since Samsung is planning a significant new feature for the upcoming Galaxy S26 that will address this issue, it appears that the company has taken user complaints into consideration. In fact, Samsung will not only increase the battery capacity of the Galaxy S26 but will also use more modern technology.
As 9to5Google revealed, the Korean site FNNews.com recently published a report claiming that the new Samsung Galaxy S26 will feature “massive” silicon-carbon batteries, which will have a capacity of between 6,000 and 7,000 mAh.
As we mentioned a few weeks ago, renowned leaker Jukanlosreve wrote on X that future Samsung Galaxy S26 phones will switch from traditional lithium-ion batteries to these new ones. This is not the first time we have heard rumors that the Galaxy S26 phone will use cutting-edge silicon and carbon batteries.
The main advantages of silicon-carbon batteries over lithium-ion batteries are that they have a lower risk of overheating, are more environmentally friendly, and, most importantly, are denser and pack more energy into the same amount of space.
This way, the batteries of the new Samsung Galaxy S26 will have a larger capacity without causing the smartphone to become larger, and in addition, they will also be more efficient than current lithium-ion batteries thanks to the silicon carbon cells.
