Samsung is preparing for the anticipated launch of its next-generation Galaxy Watches, which are expected to debut alongside new folding smartphones. A London event on July 22 is rumored for the official unveiling.
While Samsung has not yet confirmed the specific number of smartwatches it plans to introduce, charging speeds for two distinct models have recently surfaced. These details come from their appearance in 3C certification filings.
The two Samsung smartwatches, identified by model codes SM-L3550 and SM-L7150, were listed in the 3C database. Both entries clearly indicate support for 10W charging.
The SM-L3550 is widely believed to be the upcoming Galaxy Watch9, according to industry speculation. Meanwhile, the SM-L7150 is likely the successor, the Galaxy Watch Ultra 2.
