The Samsung Galaxy S25 Ultra, released in January 2025, features a 5,000mAh battery, similar to its predecessor, the S24 Ultra. Despite the unchanged battery capacity, improvements in battery life are expected due to the new Qualcomm Snapdragon 8 Elite processor, which is designed for enhanced power efficiency. This chipset reportedly offers a 27% improvement in power efficiency compared to previous models, potentially extending the device's runtime on a single charge[1][4].
In real-world testing, the S25 Ultra has shown promising results. Users have reported that after extensive use, such as watching several episodes of a series like "Squid Game 2," the device retains around 73% of its charge. This indicates that while the battery capacity remains the same, the efficiency gains from the new processor could lead to comparable or slightly improved endurance under typical usage scenarios[3][4].
However, specific battery test results are still emerging. The S24 Ultra had previously set a benchmark with a web browsing endurance of 16 hours and 45 minutes. While it is anticipated that the S25 Ultra will perform similarly or better, definitive test results for this model have not yet been published as of now[2][8].
Overall, while the Galaxy S25 Ultra maintains its predecessor's battery specifications, advancements in processing technology suggest that users may experience enhanced battery performance in everyday use.
