Summary
China 3C certification leaks point to Samsung lifting the Galaxy S27 Ultra to a 5,534mAh cell—likely marketed as 5,700mAh—after six generations of 5,000mAh Ultra batteries.
The Galaxy S27 Pro is also tipped for a 5,087mAh battery, or about 5,200mAh advertised, up sharply from the Galaxy S26's 4,300mAh and unusually large for a compact flagship.
Samsung's move would narrow a gap that widened as Apple raised the iPhone Pro Max to 5,567mAh and Chinese rivals pushed flagship batteries to roughly 7,000-8,000mAh with silicon-carbon technology.
A larger cell plus a more efficient Snapdragon chip should improve runtime, but the rumored capacities still suggest Samsung is prioritizing a cautious catch-up over setting a new battery benchmark.
