OpenIoT & ELC 2016

Mobile phones have become extremely capable and useful computer systems, but they are only available in one-size-fits-all configurations. The Ara project is changing that, defining a Linux-based platform where consumers may assemble the device they like from just the modular components they need.
Providing this sort of flexibility carries with it challenges in the area of power management. Modular components are separate from the "main" phone, and new ways must be designed to incorporate management of their power into the existing infrastructure.
"How do we do runtime power management of a module?"
"How do we ensure there's enough power to supply to a module added dynamically?"
"How do we handle the presence of multiple batteries to the system?"
These are examples of the new power management challenges we will present in this talk.
