Samsung could be testing massive batteries for the Galaxy S27 Ultra

Samsung is reportedly testing five prototypes of the Galaxy S27 Ultra, each with varying battery capacities. Leaker Kro claims the devices being tested range from 5,700mAh to 6,000mAh. If the final model adopts the higher end capacity, it would represent a significant leap over the 5,000mAh batteries used in previous generations of the Ultra.

Samsung is also reportedly exploring the use of silicon-carbon technology for its next generation of phones, which may allow for even more energy to be packed into a smaller space. However, achieving a 6,000mAh capacity may require some controversial compromises, such as removing the built-in S Pen, which could be a major decision for Samsung Ultra fans.

Despite the possibility of a more powerful battery, the most realistic prototype capacity appears to be within the 5,700mAh to 6,000mAh range. Meanwhile, Apple is reportedly preparing to bring Apple Intelligence features to its Apple TV and HomePod devices, as hinted by a new "Apple Intelligence Report" menu in the latest iOS 27 beta.
