The Galaxy S25 Ultra ships with a 5,000mAh battery, which is a capacity that Samsung has retained for multiple generations. Unsurprisingly, the lack of change in this area has been the target of severe criticism by the general populace, who invest a large sum to purchase these flagships and those who review those units. Fortunately, a new rumor claims that the company is testing future models that ship without the S Pen to see if it can increase the battery size. For those who still find multiple use cases for the accessory, a tipster claims that the Galaxy S26 Ultra will ship with it.
Other ways that Samsung is potentially increasing the battery size on the Galaxy S26 Ultra while still retaining the S Pen is the removal of a camera and exploring silicon-carbon cells
While the majority of us can agree that seeing the same battery on the Galaxy S25 Ultra has become tiresome, Samsung’s hands are pretty much tied because of the lack of room on the flagship. To overcome this hurdle, @PandaFlashPro mentions on X that the Korean giant is running tests to see if it can increase the capacity on models without holstering the S Pen. The details are scarce at this time, so it is possible that the company has initiated the early testing phase and it could expand its prototypes at a later time.
Samsung can follow the approach Apple took with its iPad Pro, where one side of the tablet can hold the Apple Pencil using strong magnets. Since the Galaxy S Ultra range also sports flat sides, incorporating the same feature should not be a problem. While the Galaxy S26 Ultra is reportedly arriving with the S Pen, Samsung is still exploring how to increase the battery size by reducing the number of cameras at the back. Thankfully, with the upcoming flagship said to feature variable aperture technology, the use of additional sensors could become redundant.
It appears Samsung might be getting rid of the Built-in S-Pen in the Future Ultra to make more room.

Another area that both Samsung and Apple are testing to increase the battery size is switching to silicon-carbon technology, and there was a rumor doing the rounds claiming that this transition could give the Galaxy S26 Ultra the ability to feature a mammoth-sized 7,000mAh cell. By shifting to silicon-carbon batteries, Samsung will not have to eliminate the S Pen in future models, and it will continue shipping its high-end smartphones with bigger capacities. We will continue to monitor the company’s progress and see what decision it comes to, so stay tuned.
