An APK teardown from Samsung’s One UI 8.5 beta build allegedly suggested that the Samsung Galaxy S26 Ultra will come with fast charging upgrades over its predecessor. The upcoming flagship may support 60W fast charging or Super fast charging 3.0. The Galaxy S25 and Galaxy S25 Edge have up to 25W fast charging, while the Galaxy S25+ and Galaxy S25 Ultra, in contrast, offer 45W speeds.
