Samsung's upcoming Galaxy Watch9 and Galaxy Watch Ultra 2 have received 3C certification, confirming their charging capabilities and battery details. Both smartwatches will support 10W charging, matching the speeds of their previous models. This certification comes as Samsung prepares to launch its next generation of wearables.

Key Highlights

• Samsung Galaxy Watch9 and Watch Ultra 2 certified with 10W charging support.
• Galaxy Watch Ultra 2 features a 784 mAh rated battery, possibly marketed as 800 mAh.
• Galaxy Watch9 40mm and 44mm models offer 382 mAh and 435 mAh batteries respectively.

Charging and Battery Specifications

The 3C certification documents show that Samsung will not increase charging speeds for the Galaxy Watch9 or the Galaxy Watch Ultra 2. Both devices will continue to offer 10W charging, the same as their predecessors. This means users should expect similar charging times as before.

However, Samsung plans to improve battery capacity in its new models. The Galaxy Watch Ultra 2 will feature a battery with a rated capacity of 784 mAh. Samsung may advertise this as an 800 mAh typical capacity. This marks a significant increase over the previous Ultra model, potentially offering longer usage between charges.

The Galaxy Watch9 will also see battery upgrades. The 40mm version is expected to have a rated capacity of 382 mAh, which could be marketed as a 400 mAh typical capacity. The 44mm variant is reported to include a 435 mAh battery, maintaining the same capacity as its predecessor.

Upcoming Launch and Model Variants

Samsung is expected to unveil the Galaxy Watch9 series and the Galaxy Watch Ultra 2 alongside other devices. The launch event may also feature the Galaxy Z Flip8, Galaxy Z Fold8, and Galaxy Z Fold8 Ultra. In addition to the standard models, Samsung is rumored to introduce the Galaxy Watch9 Classic, expanding its smartwatch lineup.

These new wearables aim to offer users improved battery life without changes to charging speeds. The larger batteries in the Ultra 2 and Watch9 models could provide extended usage, appealing to users who prioritize long-lasting performance.

Market Context and Expectations

Samsung continues to compete in the smartwatch market by focusing on battery improvements and consistent charging speeds. The company’s decision to maintain 10W charging may reflect a balance between device safety and user convenience. Larger batteries in the new models could help Samsung address user demand for longer battery life in daily use.

Official details, including pricing and availability, are expected during Samsung’s upcoming product launch event. The new Galaxy Watch9 series and Galaxy Watch Ultra 2 are likely to be key highlights of the event, alongside the latest foldable smartphones.
