First Claim
1. A method of operation of a portable communication device, the portable communication device receiving power from an accompanying power source and supporting operation of a projector, the projector being operable to project images onto a user-selected display surface spaced a distance from the portable communication device, the method comprising:
- receiving an input indicating a request to use the projector to perform a projection task, the projection task including projecting at least one image from a stored image file onto the user-selected display surface;
responsive to the request, retrieving content metadata for the stored image file;
determining, based at least on the content metadata, whether the power source has sufficient power remaining to enable the projector to complete the projection task;
in the event that the power source is determined to not have sufficient power remaining to enable the projector to complete the projection task, modifying at least one of parameters associated with the projection task and functionality of the portable communication device to increase a likelihood that the power source will be able to supply sufficient power to the projector to complete the projection task;
determining whether modifying at least one of parameters associated with the projection task and functionality of the portable communication device will enable the power source to supply sufficient power to the projector to complete the projection task; and
in the event that modifying at least one of parameters associated with the projection task and functionality of the portable communication device will not enable the power source to supply sufficient power to the projector to complete the projection task, searching for another portable communication device to which to communicate the stored image file for projected display.

Abstract
A portable electronic device implements power management to accommodate operation of a projector from the device'"'"'s power source. The portable device includes a power source, a memory, a user interface, and a processor. The memory stores an image file and associated content metadata. The user interface receives a request to use the projector to perform a projection task, wherein the task includes projecting images from the image file onto a display surface. The processor is operable to: (i) retrieve the content metadata from the memory responsive to the request; (ii) project, based at least on the content metadata, whether the power source has sufficient power remaining for the projector to complete the task; and (iii) if there is not sufficient power remaining, modify parameters associated with the task and/or functionality of the portable device in an attempt to enable the power source to supply sufficient power to the projector.
