Recent whispers from South Korea suggest that the Galaxy S26 series could feature revolutionary Si/C batteries with an impressive 7,000 mAh capacity. But a reliable tipster has confidently shot down these rumors, stating that the Galaxy S26 Ultra won’t even come close to 6,000 mAh.
The tipster said they would delete their X (formerly Twitter) account if the S26 Ultra had a 7,000 mAh or even a 6,000 mAh battery. Citing five sources, the tipster mentioned that Samsung’s test lab only has a battery with a maximum capacity of 5,550 mAh, with the actual capacity being around 5,396 mAh.
It’s important to note that the tipster did not specify whether they referred to Si/C batteries or the Li-Ion batteries currently used in the Galaxy S25 lineup. With the Samsung Galaxy S26 series launch about a year away, it’s best to wait for more information from multiple sources. We’ll undoubtedly hear more about the S26 series in the coming months as details emerge.
