Samsung Galaxy S27 Pro and S27 Ultra battery and charging specs surface via China certification
Key points
- Samsung Galaxy S27 Pro and S27 Ultra have been certified for sale in China by the 3C regulatory body.
- Both phones support 60W wired charging, unchanged from the Galaxy S26 Ultra.
- The S27 Ultra's battery is rated at 5,534 mAh in the 3C filing, which would likely be advertised as 5,700 mAh.
- A 5,700 mAh capacity would be 700 mAh larger than the S26 Ultra and would make it Samsung's largest battery in a non-folding phone.
Summary
(AI)
The specs emerged from a 3C certification filing in China on September 18, 2026, not from Samsung directly. The 60W wired charging figure is confirmed by the filing and matches the current S26 Ultra. The 5,700 mAh advertised capacity is an inference: the certified battery cell is rated 5,534 mAh, and the higher figure is the expected marketed number based on how Samsung has previously rounded cell ratings.
Samsung has not announced the S27 series. The phones are expected to launch in 2027.
