Samsung Galaxy S26 Ultra Prototype: Testing One Less Rear Camera and Introducing Higher Capacity Stacked Battery Over 5,000mAh

Samsung is reportedly conducting thorough testing on its forthcoming flagship model, the Galaxy S26 Ultra. Recent rumors suggest that one of its prototypes features a revised camera setup, opting for three rear cameras instead of the four found on the Galaxy S25 Ultra. In exciting developments, the tech giant is set to reintroduce a sought-after feature that was absent in the current model, all while experimenting with advanced stacked battery technology that promises to exceed the 5, 000mAh capacity benchmark.

Reintroduction of Bluetooth for the S Pen and Enhanced Battery Capacity

According to information shared by the user @Vhsss_God on X, the Galaxy S26 Ultra prototype is testing a compelling configuration, albeit with a notable exclusion in the camera specifications. While specific details regarding which camera has been dropped remain elusive, it appears that this change is being made to facilitate the return of variable aperture technology—previously featured in the Galaxy S9 and S9 Plus. This innovative feature aims to increase the versatility offered by a single sensor, granting Samsung the flexibility needed to streamline the camera setup.

Furthermore, fans who were disappointed by the absence of Bluetooth functionality in the Galaxy S25 Ultra’s S Pen can expect a welcome return; the prototype reportedly includes this feature. A petition advocating for the reintroduction of Bluetooth for the stylus has gained significant traction, surging from 600 signatures to over 8, 700, underscoring the demand for this capability among users.

As of now, the petition stands with 8, 706 verified signatures, highlighting the strong desire for Bluetooth integration in the S Pen. Regarding power, speculation points to the Galaxy S26 Ultra adopting stacked battery technology, with reports claiming current prototypes boasting a battery capacity of 5, 500mAh. Samsung is actively exploring methods to exceed this threshold further, potentially leveraging silicon-carbon batteries to achieve an impressive 7, 000mAh capacity.

While many of Samsung’s competitors have adopted silicon-carbon technology, which greatly enhances battery efficiency, the company had previously considered incorporating stacked batteries in the Galaxy S24 Ultra but ultimately opted against it. A notable increase in battery capacity coupled with the return of Bluetooth support for the S Pen could significantly boost the appeal of the Galaxy S26 Ultra. However, it’s essential to approach these rumors cautiously as more information becomes available.
