Ahead of a rumoured Samsung Unpacked event on 22 July, certification filings have pointed to one area where the Galaxy Watch 9 series may not advance on its predecessor, with neither of the two expected models set to offer faster wireless charging than the Watch8.
Two devices carrying model codes SM-L3550 and SM-L7150 have surfaced in China’s 3C certification database, as reported by SammyGuru, with both listed as supporting 10W charging, the same ceiling that applied to the Galaxy Watch 8 and Galaxy Watch 8 Ultra when Samsung launched those devices.
The 10W cap is a notable sticking point given that charging speed has become an increasingly competitive metric in the premium smartwatch segment, where rivals have pushed faster replenishment as a differentiator for users who wear their devices overnight for sleep tracking.
That focus on health monitoring looks set to continue across the Watch9 lineup, with both models expected to ship alongside an updated version of the Samsung Health app that restructures the user interface into five dedicated sections covering activity, mindfulness, nutrition, sleep, and vitals.
The revamped app introduces a Vitals section that tracks overnight bio-signals including blood oxygen levels, heart rate, and skin temperature, cross-referencing those readings against a user’s established resting baseline to flag meaningful deviations rather than surface raw data in isolation.
The 10W charging figure does carry a caveat worth noting: 3C certification records what a device supports at the point of submission, and Samsung has occasionally introduced charging refinements between certification and final retail hardware, so the filed specification does not guarantee the shipping product will be identical.
Beyond overnight monitoring, the updated Samsung Health app adds a Daily Cardio Load feature that quantifies cardiovascular strain across workout sessions, a Heart Health Score derived from body composition data, and a Hearing Health function that logs ambient noise exposure over time.
Full hardware specifications for the SM-L3550 and SM-L7150 remain unconfirmed ahead of the July event, though Samsung has not yet announced a formal date for any Galaxy Unpacked presentation this summer.
