Galaxy Watch 9 and Watch Ultra 2 3C Certification Confirms 10W Charging

Samsung's Galaxy Watch 9 and Watch Ultra 2 have cleared China's 3C database, with both devices appearing in an official regulatory filing issued June 3. The Galaxy Watch 9 and Watch Ultra 2 3C certification confirms the first concrete hardware spec for either device: 10W charging at 5V/2A, matching their predecessors exactly. Android Police and Android Authority both covered the filings this week under model numbers SM-L3550 and SM-L7150.

A July 22 Galaxy Unpacked event has been reported by Android Authority and SammyGuru, where the watches are expected alongside Samsung's next foldables. Samsung has not confirmed that date.

From IMEI to 3C: two different steps in the same pipeline

Four months ago, the Galaxy Watch 9 and Watch Ultra 2 first appeared in the GSMA IMEI database. Wareable described that appearance as the first concrete evidence these devices existed, noting that IMEI records have historically been reliable indicators of product roadmaps but never capture the full story, since they're just basic filings.

The 3C database entry is a different kind of record. Where the IMEI registration established that Samsung was preparing these devices, the 3C listing confirms a power specification, which is how the 10W charging figure surfaced. The progression from IMEI in February to 3C in June represents genuine movement through the development pipeline, not just a restatement of the same information.

Wareable noted in February that such certifications have typically appeared four to six months before retail launch, consistent with Samsung's previous July reveals. That pattern is what gives the current filing its weight, even if it doesn't lock in a specific date.

What the Galaxy Watch 9 and Watch Ultra 2 3C certification actually confirms

One spec, cleanly: both watches are listed with 10W charging support at 5V/2A, matching their predecessors, according to Android Police and confirmed independently by SammyGuru. Chipset details, sensors, display specs, and health features don't appear in these filings.

A separate earlier leak, flagged by Android Police, indicated the Galaxy Watch 9 may carry a 435mAh battery, the same capacity as the Galaxy Watch 8. That's a leak, not a certified specification, and carries correspondingly less certainty. Battery capacity for the Watch Ultra 2 remains unknown, Android Police notes.

Two early data points from separate sources, both pointing toward unchanged energy specs, is a pattern worth tracking even if neither is definitive. For Galaxy Watch 8 owners weighing an upgrade, the confirmed picture so far doesn't include faster charging or a larger battery in the standard model.

One caveat applies. Power input specs say nothing about software efficiency or battery management improvements. Samsung could still deliver better real-world runtime through optimization, and no regulatory filing would surface that. The 3C data rules out a charging speed increase; it says nothing about how long the watch will actually last on a charge.

Codenames suggest a broader lineup, but no filings to back it up

The regulatory record covers two models. A Wear OS APK teardown published by Android Authority in late May found codenames that appear to map to three: "Fresh 9," "Wise 9," and "Project V2," following the same naming convention Samsung used for last year's lineup. The Watch 8 was developed under "Fresh 8," the Watch 8 Classic under "Wise 8," and the Watch Ultra went by "Project X2," according to Android Authority. The "Wise 9" label suggests a Watch 9 Classic may be in development, though none of the filings reported so far include such a model.

These codenames appeared in a Google Wear OS app, not a Samsung app. Android Authority noted that detail as an interesting consideration, since it means Google may already be preparing its software for the lineup. Whether that reflects production readiness or a placeholder in the codebase is something the teardown can't answer.

The same teardown flagged a code reference that could point to raise-to-talk functionality expanding beyond the Pixel Watch. The existing RttSettingsManagerPixelWatch setting in Google code has been joined by a new RttSettingsManager3pWearOs entry, where "3p" could mean "third party," Android Authority noted. Raise-to-talk has remained a Pixel Watch exclusive since debuting with the Pixel Watch 4. Whether it reaches Samsung hardware is still speculative.

Android Authority explicitly cautions that features found in APK teardowns frequently don't make it to public releases. Both the Classic codename and the raise-to-talk reference belong in the plausible category, not the probable one.

What would actually change the picture before launch

The regulatory trail confirms two models exist and have cleared power compliance testing for the Chinese market. It does not confirm lineup breadth, software features, or any spec outside of electrical input. The broader picture of what the Galaxy Watch 9 family will include is still being assembled from fragments across different source types.

Three developments would sharpen that picture considerably. A Watch 9 Classic appearing in a regulatory database would confirm the broader lineup the codename evidence hints at. An official Unpacked date from Samsung would settle the timing question that Android Authority and SammyGuru are currently reporting as a rumor. And a leak surfacing chipset, sensor, or health feature details would fill the gap that a power compliance filing structurally cannot.

The open question heading into summer isn't whether these watches are coming. It's whether Samsung has assembled a meaningful upgrade story beyond what the available evidence can show, and that answer is still waiting on details that no certification database will ever contain.
