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 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
.
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, 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 .
All signs point to a launch at Samsung's next Galaxy Unpacked event, which is widely rumored to land on July 22, 2026 . The new watches are expected to be announced 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 .
On the design front, Samsung is likely to skip a Classic model this year. The company has traditionally alternated years between releasing a Classic or Pro variant, so the 2026 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 and MIL-STD-810H durability ratings
