The Galaxy S25 series, which includes the S25, S25 Plus, and S25 Ultra, maintains battery capacities identical to their predecessors, the S24 models. Specifically, the S25 has a 4,000 mAh battery, the S25 Plus has 4,900 mAh, and the S25 Ultra features a 5,000 mAh battery[1][6][8]. Despite these unchanged capacities, improvements in battery life are anticipated due to the introduction of the Snapdragon 8 Elite processor, which boasts enhanced power efficiencyâreportedly up to 44% better for CPU performance and 40% for GPU performance compared to the Snapdragon 8 Gen 3 used in the S24 series[1][9].
Initial tests indicate that the Galaxy S25 Ultra can achieve a charge from 0% to 70% in about 30 minutes and reach full charge in approximately 57 minutes with its 45W charging capability[2]. This is an improvement over the S24 Ultra's performance, which achieved around a 60% charge in the same timeframe[2][5]. Battery drain tests have also shown promising results; for example, the S25 Ultra lasted about seven hours and five minutes under heavy usage conditions, placing it competitively among other recent flagship models[2].
While the charging speeds remain unchanged at 25W for the standard model and 45W for the Plus and Ultra models, Samsung has not introduced any new wireless charging capabilities beyond what was available in previous iterations[1][6]. However, users can now access detailed battery health information directly within the settings of their devices, a feature not present in earlier models[3][4].
In summary, while the Galaxy S25 series does not offer larger batteries than its predecessors, advancements in processing efficiency and software optimizations are expected to enhance overall battery life compared to previous models.
