Galaxy S27 Pro and Ultra tipped for bigger batteries
A Chinese certification listing suggests the Galaxy S27 Pro could use a 5,200mAh battery and the Galaxy S27 Ultra a 5,700mAh cell, both with 60W wired charging. A separate leak indicates 12GB of RAM across most models, with 16GB reserved for the 1TB Ultra, plus faster UFS 5.1 storage and LPDDR6 memory. Because memory prices are high, the series may cost more than previous generations.
The 3C listing points to a 5,200mAh cell in the Galaxy S27 Pro and a 5,700mAh cell in the Galaxy S27 Ultra. Both are said to support 60W wired charging. The Ultra's capacity would be about 14% higher than the 5,000mAh Galaxy S26 Ultra, while the smaller Pro could still exceed the S26 Ultra's battery.
A separate Naver leak suggests 12GB RAM for most S27 variants, with 16GB limited to the 1TB Ultra. The Pro and Ultra are also tipped for UFS 5.1 storage and LPDDR6 memory. With memory prices elevated, the lineup may cost more than earlier generations.
Larger batteries and faster memory could appeal to frequent travelers, commuters, and mobile gamers who rely on phones for navigation, work, and entertainment. Longer runtime may reduce midday charging anxiety, while higher possible prices could make upgrades less accessible for budget-conscious buyers. The shift may also pressure rivals to prioritize battery life and efficiency, though real-world gains will depend on software and chip power demands.
