Yesterday (December 1), Android Authority published a teardown of the firmware for One UI 8.5 and discovered a new string: “Super fast wireless charging,” directly confirming that Samsung is preparing to upgrade its wireless-charging technology.
In the current One UI 8 code, Samsung’s strings for wireless charging are limited to two states: “Wireless charging” (for 5–10 W wireless) and “Fast wireless charging” (for 15 W wireless).
But in One UI 8.5, a third string has been added:
This explicitly points to a “super‑fast wireless charging” mode, echoing previously leaked wired‑charging branding (e.g., “Super Fast Charging 3.0”).
When combined with earlier supply‑chain rumors, the report suggests that on the upcoming Galaxy S26 Ultra, wireless charging power could reach 25 W — and that the standard Galaxy S26 / Galaxy S26 Plus might also see a bump from the long‑stagnant 15 W to around 20 W.
At the same time, S26 Ultra is rumored to support as much as 60 W via PPS wired charging — meaning if everything lands, Samsung’s next‑gen flagships could see roughly a 40% improvement in overall charging efficiency, significantly reducing users’ battery anxiety.
Given Samsung’s historically conservative charging strategy — since the 2020 Galaxy S20 series, its flagships’ wireless speeds have been stuck at 15 W, while many Android competitors already pushed proprietary wireless charging to 50 W or even 80 W — this One UI 8.5 code leak is widely considered a strong signal that Samsung finally plans to make up for a five‑year charging‑tech lag.
In short: the discovery of a “Super fast wireless charging” string in One UI 8.5 — combined with rumors of 25 W / 20 W wireless and 60 W wired charging for the S26 series — suggests Samsung may soon substantially upgrade the charging experience of its flagship phones.
