Samsung Galaxy S26 Ultra Battery Capacity Confirmed: No Change from S25 Ultra

Samsung’s Galaxy S26 Ultra has recently passed certification, confirming a battery capacity of 4,855 mAh. This is the same as the S25 Ultra, which has an advertised typical capacity of 5,000 mAh. While many speculated that the S26 Ultra might receive a battery upgrade, possibly pushing the capacity to 5,500 mAh, those hopes have been dashed.

Despite the rising trend of Chinese flagship phones packing larger batteries – some up to 7,000 mAh – Samsung appears to be sticking with its current approach.

Though the battery capacity isn’t changing, the S26 Ultra could bring some improvement in the charging department. Rumors suggest that Samsung might increase the charging speed to 65W, which would be a significant step up from the 45W charging limit seen in previous models. However, it’s unclear whether this change will be enough to make up for the lack of a larger battery. Other brands have been more aggressive in their battery capacity, but Samsung is focusing on battery efficiency and longer-lasting performance over raw capacity.

One potential reason for Samsung’s decision could be regulatory constraints. In some regions like the US and EU, batteries over 5,000 mAh are classified as “dangerous goods,” making it difficult and expensive to ship. Furthermore, Samsung’s focus on delivering more software updates might play a role in its decision to stick with the 5,000 mAh mark, as larger batteries, particularly silicon-carbon ones, degrade faster. Thus, the company may want to ensure the battery lasts for several years without performance issues.

While some fans are disappointed by the lack of battery improvements, others point out that Samsung’s battery life and charging efficiency still outpace competitors. With its 4,400 mAh battery, the Galaxy Z Fold 7, for example, delivers impressive performance, and Samsung promises a longer lifespan for its batteries compared to some Chinese brands. Despite the industry’s push for larger batteries, Samsung’s more conservative approach may prove beneficial in the long run, ensuring that users get a device that holds up over time.

It’s also worth noting that the S26 Ultra’s battery isn’t the only feature under scrutiny. Many are eager to see if Samsung can maintain its reputation for top-tier performance and reliability, even without embracing the massive battery capacities that other brands are offering.
