Kyocera Solar Phone First Look

The Kyocera rep we spoke to on the show floor in Barcelona couldn't be any more specific than that, but he did say the tech is almost ready to go, and much closer to officially launching than it was in 2015. It uses a 0.55 mm-thin pane that sits between the display and its touchscreen layer, giving you a battery charge that equates to 1 minute of talk time for every 3 minutes of direct sunlight – that's an 8x efficiency improvement from the demo model Kyocera brought to MWC last year.
