What the 3C Certification Reveals About Samsung’s Next Watches
Samsung Galaxy Watch 9 charging specifications and Watch Ultra 2 specs refer to the officially certified power and charging capabilities recorded in regulatory listings, which confirm how quickly these upcoming smartwatches can refill their batteries and what chargers they are designed to work with before Samsung’s formal launch announcements. Two unreleased Samsung wearables with model numbers SM-L3550 and SM-L7150 have appeared on China’s 3C certification database, a mandatory checkpoint for electronic devices that lists charging wattage and supported adapters. While 3C filings do not confirm product names, prior reports link SM-L3550 to the Galaxy Watch 9 and SM-L7150 to the Galaxy Watch Ultra 2, giving an early look at their charging behavior. These listings matter because they set expectations for smartwatch charging speed and hint at whether Samsung plans an aggressive hardware upgrade or a more incremental update this generation.
Same 10W Charging as Galaxy Watch 8 and Watch Ultra
The most direct takeaway from the 3C certification wearables listing is that both upcoming watches support 10W charging. According to GSMArena, the SM-L3550 and SM-L7150 entries show “support for 10W charging,” matching the Galaxy Watch 8 and Galaxy Watch Ultra before them. The Tech Outlook notes that these new models are again paired with Samsung’s EP-T1510 travel charger, the same adapter referenced for the previous generation. That combination strongly suggests there is no headline-grabbing jump in raw charging wattage this cycle. For users, this likely means Galaxy Watch 9 charging times will feel similar to the Watch 8, and Watch Ultra 2 specs in the charging department will track closely with the first Watch Ultra, rather than chasing the fastest charging speeds seen on some rival wearables.
What This Means for Battery Life and Daily Use
With smartwatch charging speed apparently locked at 10W again, any meaningful improvement in day-to-day experience will need to come from efficiency gains or larger batteries, not from faster power delivery alone. GSMArena points out that the Galaxy Watch 8 and Galaxy Watch Ultra had the same charging speed, adding that “here’s hoping the Watch9 and Watch Ultra 2 will at least offer better battery endurance.” Even without faster charging, Samsung could extend usable time per charge through a more efficient chipset, refined display settings, or software optimizations in the new Samsung Health experience. If battery capacity grows while keeping 10W charging, top-up sessions might be slightly longer, but users could charge less often. For most people, overnight charging habits would remain unchanged, while quick top-ups before workouts might feel familiar compared with current models.
Launch Timing, Classic Model, and What to Watch Next
These 3C listings arrive as Samsung prepares its next Galaxy Unpacked event, currently rumored for July 22, where new folding smartphones and wearables are expected. Both sources suggest the Galaxy Watch 9 and Watch Ultra 2 will debut alongside the foldables, with The Tech Outlook also mentioning a possible Galaxy Watch 9 Classic that is “expected to be introduced” with the same 10W charging support. While Samsung has not confirmed model names or full Watch Ultra 2 specs, it has publicly said that multiple new Galaxy Watches are coming with fresh health features tied to an updated Samsung Health app. With charging details now largely settled by certification, the remaining open questions focus on battery capacities, processor efficiency, health sensors, and software features that could make these watches feel like a clear upgrade despite the unchanged charging wattage.
