Galaxy S26 Edge Expected to Have Larger Battery Capacity, Exceeding 4,200mAh Amid Conflicting Specification Reports

Samsung has made remarkable advancements with the Galaxy S25 Edge, achieving a sleek thickness of only 5.84mm. However, this design comes with certain trade-offs, one notable compromise being the device’s reduced battery capacity of 3, 900mAh. The motivation behind this model, whether to test the waters for market acceptance or another reason, remains open to speculation. Nevertheless, anticipation is building for its successor, the Galaxy S26 Edge, expected to debut next year with significant enhancements, particularly in battery performance. Recent reports suggest that this new iteration may feature a larger battery than previously indicated, adding another layer of intrigue to the specifications.

Rumored Specifications: Galaxy S26 Edge to Feature a 4, 400mAh Battery

According to the well-known tipster, Ice Universe—now operating under the name PhoneArt—the anticipated Galaxy S26 Edge may come equipped with a 4, 400mAh battery. This update conflicts with earlier reports that suggested the device would have a 4, 200mAh capacity, while the base model, now referred to as the Galaxy S26 Pro, was expected to have a 4, 300mAh battery. PhoneArt mentioned the need to verify this information with their sources, highlighting the possibility that Samsung could be testing various prototypes for the Galaxy S26 Edge.

Prior to the launch of the Galaxy S25 Edge, there were rumors of two prototypes under consideration; one of which was 6.4mm thick and featured a triple-camera setup. Ultimately, Samsung opted for the ultra-slim design we see now, finalizing the dual-camera configuration of the Galaxy S25 Edge. With the upcoming Galaxy S26 Edge, it is plausible that a variant may include the larger 4, 400mAh battery, while still achieving a thinner design through innovative internal component arrangement.

The battery information I got for the S26 Edge is 4400mAh. There seems to be some conflict here, I will double-check the information.

In addition to a larger battery, PhoneArt has suggested that the Galaxy S26 Edge will also be slimmer than its predecessor, thanks to Samsung’s potential use of advanced materials to enhance battery capacity. However, it remains unclear whether the tech giant has adopted silicon-carbon technologies, as inferred from the current capacities observed in other Galaxy S26 models.
