Previous details from China's 3C certification database allegedly indicated that the Samsung Galaxy S27 Ultra could feature a 5,534mAh battery unit, which is likely to be marketed as 5,700mAh. The Galaxy S27 Pro is tipped to feature a 5,087mAh-rated battery, which is expected to be translated to 5,200mAh. Both models are expected to support 60W wired charging.

If this rumour turns out to be correct, the Galaxy S27 Ultra could offer a larger battery than the 5,000mAh unit found in the Galaxy S26 Ultra. The Galaxy S26 has a 4,300mAh battery, while the Galaxy S26+ has a 4,900mAh unit.

The certified battery samples found in the Safety Korea database could be prototypes and differ from the components used in final retail devices. Therefore, these details are recommended to be considered with a pinch of salt.
