Leaked firmware information suggests that the upcoming Samsung Galaxy S26 Ultra may come equipped with significantly faster charging capabilities, according to a source familiar with the details. This enhancement would represent a marked improvement over the Galaxy S25 Ultra, which is limited to 45W fast charging. The new insights align with prior speculation that indicated the phone could feature faster charging technology. Initial rumors hinted at support for 65W charging alongside a 5,500mAh battery.
Samsung Galaxy S26 Ultra May Feature Enhanced Charging
In a recent post on X (formerly Twitter), tipster Erencan Yılmaz (@erenylmaz075) revealed that the Galaxy S26 Ultra could potentially support 60W fast charging. This information was uncovered in the firmware details related to an upcoming version of One UI, specifically One UI 8.5. If verified, this suggests that Samsung might be aiming to offset the lack of an increase in battery capacity or perhaps provide a marginally larger battery within the new model.
While earlier reports indicated the possibility of 65W fast charging and a 5,500mAh battery for the Galaxy S26 Ultra, there have been conflicting suggestions that Samsung may opt not to increase battery capacity. Consequently, the introduction of improved charging capabilities could serve as a compensatory measure. As Samsung has yet to officially confirm any specifications, the actual approach the company may take remains uncertain.
The recent leak regarding the One UI 8.5 update, anticipated to be based on Android 16, also hinted that the Galaxy S26 Ultra could be powered by the Qualcomm Snapdragon 8 Elite 2 SoC, expected to be officially announced in September.
The Galaxy S26 Ultra is projected to debut early in the coming year. Speculated features include 16GB of RAM, a 6.9-inch display, and IP68-rated water and dust resistance. Additionally, the device is rumored to house a 200-megapixel ISOCELL HP2 camera sensor, accompanied by a 50-megapixel ultra-wide-angle lens, a 12-megapixel telephoto lens, and a 50-megapixel periscope camera.
