Summary

  • 3C listings show Samsung’s Galaxy S27 Ultra at a 5,534mAh rated capacity—typically marketed as 5,700mAh—and the Galaxy S27 Pro at 5,087mAh, or 5,200mAh typical.
  • Those figures validate earlier leaks and mark a notable jump from the Galaxy S26 Ultra’s 5,000mAh battery, pointing to a larger power upgrade in Samsung’s next flagship cycle.
  • Both models had already cleared 60W wired-charging certification, extending the faster charging Samsung introduced on the Galaxy S26 Ultra earlier this year.
  • Silicon-carbon cells are widely expected to enable the higher capacities without thicker batteries, after Samsung already used the technology in the Galaxy Z Fold 8 and Flip 8.
  • An official launch is still expected in early 2027, leaving months for further Galaxy S27 specifications to emerge through certifications and leaks.
