The Galaxy S25 Ultra’s battery has been retained at 5,000mAh, a figure that has not budged an inch for several generations, indicating that nothing can change unless Samsung transitions from lithium-polymer batteries to improved technology. As it so happens, the Korean conglomerate is reportedly reviewing a plan that will allow it to incorporate silicon-carbon cells into its upcoming Galaxy S26 series. This move, assuming the company follows it, will enable it to cross the 5,000mAh capacity threshold and enter the mammoth-sized 7,000mAh range, resulting in a record ‘screen on’ time.
The biggest hurdle that reportedly concerns Samsung is product stability issues that can arise if it employs silicon-carbon batteries in the Galaxy S26 lineup
Both Apple and Samsung have previously been reported to switch to silicon-carbon batteries, a move that will not compromise the thickness of smartphones but will guarantee bigger-sized cells. There is no word on when Apple will introduce the first iPhone with this technology, but Fnnews believes that the Galaxy S26 family will be the first to debut this massive internal change. The report that was spotted by @Jukanlosreve states that Samsung could cram in batteries in the 6,000mAh to 7,000mAh range.
However, it is understandable that the company would have some apprehension in gravitating to silicon-carbon technology. While a host of Chinese smartphone makers have happily embraced this change, the report mentions that Samsung has been conservative about this approach as it produces more devices than any other OEM in the world that takes advantage of Google’s Android platform. This reason alone can increase the risk of stability issues, potentially turning into another Galaxy Note 7 catastrophe, with Samsung having to deal with yet another PR nightmare.
This conservative stance might also explain why Samsung is hesitant to introduce fast charging technologies for its smartphones, with its Galaxy S25 family still limited to up to 45W. There is no question that supplying a higher wattage can adversely affect battery health, so we will not criticize Samsung for wanting to boost the longevity of its devices. However, we do hope that the company kicks off mass production of silicon-carbon batteries, as it will allow the Korean firm to remain competitive with other players and perhaps even pressure Apple to switch to this technology.
