Samsung may finally move away from the 5,000mAh battery capacity that has remained a fixture of its Ultra-series flagships for years. Leaked certification information suggests the upcoming Galaxy S27 Ultra could carry a rated 5,534mAh battery, while the Galaxy S27 Pro is reportedly set to feature a 5,087mAh cell.
Using Samsung’s usual method of presenting advertised battery capacity above the rated figure, the Galaxy S27 Ultra could be promoted with a 5,700mAh battery. That would mark a substantial increase over the 5,000mAh battery used in the Galaxy S26 Ultra.
