Samsung is preparing to increase the charging speed of its flagship Galaxy S series, with leaked software details pointing to a potential 60W capability for the Galaxy S26 Ultra expected in early 2026. the move signals continued competition in the smartphone market to reduce charging times, a key factor for many consumers. While Samsung has historically favored the universal USB Power Delivery standard, its pace of adoption trails some competitors who utilize proprietary fast-charging technologies offering significantly higher wattage. This update comes as battery technology and power management become increasingly central to smartphone innovation.
Samsung is reportedly planning to significantly increase charging speeds in its upcoming Galaxy S26 Ultra, slated for release in 2026. The move comes as smartphone manufacturers continue to push the boundaries of power delivery, aiming to minimize downtime for users.
Details surrounding the new charging capabilities began to surface through leaked software files. Specifically, the One UI 8.5 interface includes references to “Super Fast Charging 3.0,” which is expected to deliver up to 60W of power.
Tech enthusiasts have been dissecting the firmware files for One UI 8.5, uncovering hints of forthcoming features. Android Authority identified text strings within the files that confirm the presence of “Super Fast Charging 3.0.” While the exact wattage isn’t explicitly stated, the evidence strongly suggests a 60W charging speed, aligning with previous leaks.
Despite the “Super Fast Charging 3.0” branding, Samsung’s potential 60W offering lags behind some competitors. Companies like Honor, with its Magic 8 Pro, and OnePlus, with the OnePlus 15, already offer devices capable of 120W fast charging – double the speed anticipated for the Galaxy S26 Ultra.
Samsung first introduced fast charging with the Galaxy S6 series in 2015, initially at 15W. The company then increased this to 45W with the 2020 Galaxy S20 Ultra, before briefly reducing it to 25W with the Galaxy S21 Ultra. Samsung returned to 45W charging with the 2022 Galaxy S22 Ultra, and now appears poised to upgrade to 60W with the Galaxy S26 Ultra in early 2026.
While many Chinese smartphone manufacturers offer charging speeds ranging from 80W to 240W, they typically rely on proprietary charging protocols to achieve these rates. Apple, Google, and Samsung, however, adhere to the USB Power Delivery (PD) standard for fast wired charging, simplifying compatibility with a wider range of chargers.
The adoption of USB Power Delivery ensures consumers can easily find compatible charging accessories, a benefit that prioritizes convenience alongside speed. This approach reflects a broader industry trend towards standardized charging solutions.
