Frequently asked questions
Q. The Wireless power sharing feature is not working on the Galaxy Watch7 / Galaxy Watch Ultra.
A. The Galaxy Watch7 / Galaxy Watch Ultra has a new rear sensor design to improve sensor accuracy over previous models. As a result, it is possible to assess health-related data points that were not previously supported as well as take more reliable measurements during prolonged or specialized exercises.
However, the new sensor design required changing the shape of the back glass. The alteration increased the distance between the internal wireless charging coil of your Watch and the wireless charger, so the Wireless power sharing feature available on the previous model is no longer supported.
We appreciate your understanding.
