Galaxy Watch 9 & Ultra 2 Leaks: Qualcomm Chip Inside, 10W Charging Stays

No Fast-Charging Breakthrough: 10W Stays

For those hoping to refuel their watch more quickly, the news is stagnant. Recent 3C certification documents from China confirm that both the Galaxy Watch 9 and Galaxy Watch Ultra 2 support 10W wireless charging—identical to the Galaxy Watch 8 and the original Galaxy Watch Ultra . The 3C, or China Compulsory Certificate, is a mandatory safety certification required for electronic products sold in the Chinese market, making these filings a reliable indicator of final hardware specifications.

The filings, which list model numbers SM-L3550 for the Watch 9 and SM-L7150 for the Ultra 2, show no indication of Samsung moving to a faster charging standard this year . This aligns with earlier reports forecasting no significant hardware design changes or improvements in charging capabilities for the new models .

Battery Capacity: Familiar Numbers, New Efficiency

The battery capacities for the Galaxy Watch 9 appear to be a direct carry-over from the previous generation. The 44mm model is widely expected to keep a 435mAh battery . For the smaller 40mm variant, battery certifications point to a capacity of roughly 382mAh .

Batteries for both the Galaxy Watch 9 and Watch Ultra 2 passed through the Indian BIS certification database—the Bureau of Indian Standards is the national standards body that certifies products for the Indian market—confirming that mass production is imminent . While the exact battery size for the Galaxy Watch Ultra 2 has not been widely disclosed, the BIS filing included components with codenames EB-BL345DAY and EB-BL715DAY, tying them to the new watch generation .

Even if the raw milliamp-hour ratings don't impress, real-world usage should see gains. The shift to the more efficient 3nm Snapdragon chip is expected to improve battery life despite the unchanged battery size. One report even suggests a potential efficiency increase of up to 30%, which would deliver extended usage without a physical battery bump .

Launch Timeline and What Else to Expect

All signs point to a launch at Samsung's next Galaxy Unpacked event, which is widely rumored to land on July 22, 2026 . The iconic Unpacked event, where Samsung traditionally unveils its flagship mobile devices, is expected to showcase these watches alongside the Galaxy Z Fold 8 and Z Flip 8, continuing Samsung's tradition of a summer wearable and foldable refresh . Market availability should follow roughly two weeks after the announcement .

A firmware test build for the Galaxy Watch 9 (model SM-L345U) was discovered on Samsung's U.S. servers in late March 2026, a sign that hardware development is essentially complete and Samsung is in the final stage of software optimization before mass production begins .

On the design front, Samsung is likely to skip a Classic model this year. The Classic variant, known for its physical rotating bezel and more traditional watch aesthetic, has historically alternated release years with Pro or Ultra models. For 2026, the lineup is expected to include only the Galaxy Watch 9 in 40mm and 44mm aluminum sizes and the Galaxy Watch Ultra 2 . Both sizes are expected to retain their 5ATM water resistance, meaning they can withstand pressures equivalent to a depth of 50 meters, and MIL-STD-810H durability ratings, a U.S. military standard that certifies resilience against extreme temperatures, shock, and vibration .

Potential pricing remains speculative, but if Samsung holds the line, the entry-level Bluetooth models could start between $349 and $379 .
