Abstract: This document describes systems and techniques directed at internal hardware configurations for foldable devices. In aspects, a foldable electronic device includes a housing, defining an internal cavity within which a battery is disposed, and one or more displays that are fixed to the housing, forming at least one internal cavity. The foldable electronic device further includes one or more battery cell tabs that are arranged in an unfolded configuration and extend from the battery to a power control module positioned underneath a display control module that is mounted to the display. Through such a configuration, an internal volume within the internal cavity can be more-efficiently occupied by increasing a battery capacity or reducing a dimensional profile of the foldable electronic device.
