As phones become able to do more and are used for more intense operations, their batteries suffer and processor limitations get tight, so operations take longer while the charge lasts for a shorter time. To combat the issue, several engineers present a possible I/O interface with bi-directional dual-band signaling, to improve energy efficiency and increase bandwidth.
