Samsung launched the world’s first solar-powered phone at the Mobile World Congress technology event.
The phone is designed to resemble the shape of a shiny pebble, and uses a small solar panel to provide power. Samsung said it underlined the Korean company's commitment to environmental stability.
A full solar charge of around 10 to 14 hours will provide enough power for around four hours of talk time. The handset can still be charged normally using a conventional plug, with the solar panels used to top up the battery during use.
"This phone demonstrates our small but meaningful commitments for the future and our environment," said JK Shin, an executive vice president at Samsung.
