Supply chain rumors have asserted that a second-generation Apple Watch 2 could offer a few additional hours of battery life while replacing the current models' Glass on Glass (G/G) touchscreen with a thinner and lighter screen based on One Glass Solution (OGS) display technology. These two features—a thinner display assembly and a bigger battery—are allegedly shown in a video posted by Byte, a UK-based retailer that sells Apple-certified accessories.
