The new Galaxy Watch 7 and Watch Ultra feature faster charging and an improved sensor rack. But that forces it to remove a very useful feature.
The Galaxy Watch 7 and the Watch Ultra were launched earlier this week with upgraded internals and a new BioActive Sensor. While the improved sensor is claimed to be more efficient than before, it forced Samsung to remove a key feature previously unique to the Galaxy Watch lineup.
Older Samsung Galaxy Watch models — including the Galaxy Watch 6 — could be charged when placed on the back of a Samsung phone that supports wireless charging. This functionality relies on “Wireless power sharing,” commonly known as reverse wireless charging, which allows Samsung phones to add battery life to accessories such as earbuds and select Galaxy Watches through wireless charging.
Several past generations of Samsung flagships, including the newly announced Galaxy Z Flip 6 and Fold 6, have supported reverse charging. The maximum output is limited to only 4.
