Samsung’s upcoming flagship is taking clearer shape once more, as new certification paperwork points to the Galaxy S27 supporting a familiar fast-charging profile. After earlier 3C listings hinted at 25W wired charging, Denmark’s UL Solutions (Demko) certificates have now appeared for several Samsung models associated with the Galaxy S27 lineup, reinforcing those expectations.

The certification details show a rated output of 9V DC and 2.77A, which works out to approximately 24.93W. In practical terms, that means the device is expected to be marketed with 25W wired charging support, the same figure associated with the Galaxy S26.

Wireless charging remains a related point of interest. The Galaxy S26 supports 15W wireless charging, and current expectations suggest the Galaxy S27 will continue with that same wireless charging speed. Battery capacity details have not yet been fully confirmed, leaving open whether the next model will keep the Galaxy S26’s reported 4,300 mAh battery.
