Samsung has filed a patent for a smartwatch powered directly by solar energy, thanks to tiny solar panels inserted into its strap. Does that mean the forthcoming Galaxy Watch 5 could be equipped with this new technology? In any case, it seems that Samsung is exploring the possibility.

Could one version of the Samsung Galaxy Watch 5 – which is not expected until summer 2022 – be set to land with solar cells, potentially boosting its battery life tenfold, especially in good weather? Indeed, the South Korean manufacturer filed a patent with the US Patent and Trademark Office (USPTO) in 2019, which was completed and published only recently. It has just been brought to light by Dutch site LetsGoDigital.
