A leak suggests the Samsung Galaxy S27 Pro and Galaxy S27 Ultra will ship with larger batteries than their predecessors, though they still won’t match the extreme capacities offered by some Chinese flagships.
Revealed capacities for the premium models
– The Galaxy S27 Pro is said to use a battery with an actual capacity of 5,028 mAh, which Samsung could market with a typical capacity figure of around 5,200 mAh.
– The Galaxy S27 Ultra reportedly houses a 5,534 mAh cell, which may be presented by Samsung as a typical battery in the 5,700–5,800 mAh range.
A modest increase over the previous generation
These figures represent an uplift compared with the Galaxy S26 lineup, where the compact model had a 4,300 mAh battery and the Ultra used a 5,000 mAh pack. The increase points to a move toward beefier batteries, but still falls short of some Chinese competitors that occasionally ship batteries north of 7,000 mAh.
Other expected improvements
The leak also claims both high-end S27 models will use Qualcomm’s new Snapdragon 8 Elite Gen 6, include an improved 16 MP front-facing camera with a potentially square-shaped sensor, and debut a new 50 MP telephoto lens. Additionally, the entire S27 range is said to support the Privacy Display feature seen on the previous generation.
What remains to be confirmed
There’s no battery information yet for the Galaxy S27 and S27+. Final capacities, the marketing figures Samsung will use, and the real-world impact on battery life will depend heavily on software optimizations and power-management tuning—details the leak does not provide.
Timing
The Galaxy S27 series is expected to be unveiled in early 2027. Until then, these early leaks offer a preview of Samsung’s priorities for battery life and imaging, while underscoring that the company is not chasing the highest-capacity records set by some rivals.
