The Samsung Galaxy Watch9 and Watch Ultra 2 have officially passed 3C certification in China, revealing their charging speeds—but the figures fall short of expectations for what many users and analysts had hoped for. According to GSMArena’s verification of the 3C database, both models support 10-watt (10W) wired charging, a standard that aligns with the Galaxy Watch8 series released in 2024 but does not match the faster 15W or 20W charging seen in competitors like the Apple Watch Series 10 or Huawei Watch GT 4.
This confirmation comes as Samsung prepares to launch the Galaxy Watch9 and Watch Ultra 2, with pre-orders and official announcements expected in the coming weeks. The 10W charging speed means users can expect roughly 20–30 minutes of charge time for a 10% battery boost, depending on the model’s battery capacity. While this is adequate for daily use, it positions Samsung’s latest wearables as trailing behind rivals in terms of speed, despite other improvements expected in software, health tracking, and display technology.
Why the Charging Speed Matters—and What It Means for Users
Charging speed is a critical differentiator in the smartwatch market, directly impacting convenience and battery management. The Apple Watch Series 10, for example, supports 15W charging, allowing for a full charge in under 90 minutes, while the Huawei Watch GT 4 offers 20W charging for even faster top-ups. Samsung’s decision to stick with 10W—despite industry trends toward faster charging—could influence buyer decisions, particularly among power users who prioritize quick recharging.
For context, the Galaxy Watch8 series (launched in 2024) also used 10W charging, meaning the new models are not introducing a meaningful upgrade in this area. This contrasts with Samsung’s broader smartphone strategy, where the Galaxy S24 series introduced 45W fast charging and the Galaxy Z Fold 5 supported 45W wireless charging. The discrepancy raises questions about whether Samsung is prioritizing other features—such as battery longevity, software optimizations, or hardware refinements—over charging speed in its wearable lineup.
What Comes Next for Samsung’s Wearables
While the charging speed may not be a standout feature, other aspects of the Galaxy Watch9 and Watch Ultra 2 are likely to draw attention. Leaks and early reviews suggest improvements in:
- Health tracking, including enhanced ECG and blood oxygen monitoring.
- Software, with tighter integration into Samsung’s One UI ecosystem and potential AI-driven health insights.
- Design, with rumors of a more premium build for the Ultra 2 variant.
Samsung has not yet confirmed an official launch date, but the 3C certification—required for sales in China—indicates the devices are nearing readiness. Pre-orders may begin as early as late June 2026, with widespread availability following shortly after.
How This Compares to Competitors
To put Samsung’s charging speed in perspective, here’s how it stacks up against recent releases from key rivals:
| Smartwatch Model | Charging Speed | Full Charge Time (Est.) |
|---|---|---|
| Samsung Galaxy Watch9 | 10W | ~2.5–3 hours |
| Apple Watch Series 10 | 15W | ~1–1.5 hours |
| Huawei Watch GT 4 | 20W | ~45–60 minutes |
| Google Pixel Watch 2 | 10W | ~2.5–3 hours |
While Samsung’s choice of 10W charging may disappoint speed-focused users, the company has historically emphasized battery efficiency in its wearables. The Galaxy Watch Ultra 2, for instance, is expected to feature a larger battery (likely 500mAh or more) to support extended usage, which could offset the slower charging time for some consumers.
The Bottom Line
For tech enthusiasts and early adopters, the Galaxy Watch9 and Watch Ultra 2’s charging speed may not be a dealbreaker—but it is a notable omission in an otherwise competitive wearable market. Samsung’s decision to maintain 10W charging suggests a focus on other areas, such as software and health features, rather than pushing the boundaries of fast charging. Users prioritizing speed may look to Apple or Huawei, while Samsung loyalists can expect refinements in design and functionality.
As always, the full picture will emerge closer to launch, when Samsung reveals pricing, additional specifications, and any late-stage surprises. For now, the 3C certification confirms one key detail: the Galaxy Watch9 and Watch Ultra 2 are ready for their debut, even if their charging speeds won’t turn heads.
