Multiple reports say Samsung’s next Galaxy S27 lineup is expected to feature a significant battery capacity increase, potentially addressing longstanding complaints about limited growth in the Ultra model. Leaks referenced by Digital Trends suggest that the Galaxy S27 Pro could reach about 5,200mAh, while the Galaxy S27 Ultra could move to roughly 5,700mAh or more. 9to5Google similarly reports a long-awaited battery upgrade for the Galaxy S27 Ultra, describing claims that its capacity could be close to 6,000mAh.
Both outlets frame the change as a meaningful shift from recent battery figures, noting that the Ultra’s battery capacity has not substantially increased over multiple generations. The Digital Trends report also points to the use of silicon-carbon technology as part of how Samsung may achieve the higher capacity.
These figures are presented as rumors and leaked specifications rather than confirmed details from Samsung. No release date, pricing, or real-world battery-life performance claims are included in the shared reporting.
