Updated July 12 with new chassis design details.

Samsung may have revealed the Galaxy Z Fold6 and Z Flip6 this week at the latest Galaxy Unpacked event. While technically accomplished, these phones are very much the gee-whizz of Samsung’s commercial offerings. The regular flagship Galaxy S Ultra carries that responsibility. Now we know more about the next premium phone, the Galaxy S25 Ultra.

The latest details come courtesy of India’s Bureau of Indian Standards. While it is some six months away from a presumed launch, the government department has certified two batteries destined for the Galaxy S25 Ultra.

Beyond the two part numbers (EB-BS938ABE and EB-BS938ABY), the certification is short on any other details. Samsung has used multiple suppliers in previous years, so it’s likely that, just as it did with the Galaxy S24 Ultra, these two model numbers represent two different suppliers.

Since the first Galaxy Ultra was launched in 2020, each model has sported a 5,000 mAh battery. However, updating the actual technology in the battery’s hardware and the software regulating the power used by the smartphone has allowed the endurance of each model to meet the expected benchmarks.

Samsung is expected to continue using a 5,000 mAh battery in next year’s Ultra handset. no doubt continuing to refine its OneUI software to offer better battery life. With competing handsets offering more capacity, such as the OnePlus 12’s 5,450 mAh or the ROG Phone 8’s 5,400 mAh, there will be many asking if it’s time to increase the battery capacity of the top-tier Galaxy Ultra in its sixth year.

Update: Friday July 12. New details on the design have also been reported by noted leaker Ice Universe. Publishing details on X, they highlight a new design for the internal frame of the upcoming Galaxy S25 Ultra.

The frame will be asymmetrical, with an angular front side and more chamfer on the rear edges. This would offer Samsung a smartphone with more curves at the rear and a more comfortable grip, while the front would have a flatter profile that could push right to the edges and corners, allowing for a larger screen with smaller bezels.

The recently released Galaxy Z Fold6 and Z Flip6 models have seen a more angular and sharper design, especially at the corners. That could easily continue on the Galaxy S25 Ultra screen. Still, with no need to fold the handset, creating a more ergonomic rear would be possible while retaining a similar expanisve design around the display.
