Patent ID: 8477041

Claim:
A wireless communication method, comprising: providing a multi-mode communication device including an unrestricted mode having an unrestricted operation temperature range, a restricted mode having a restricted operation temperature range and a warning mode having a warning operation temperature range; determining if a temperature in proximity to an energy storage device is in at least one of the restricted operation temperature range, the unrestricted operation temperature range and a warning operation temperature range; entering the warning mode when in the warning operation temperature range, wherein the warning mode includes a high temperature alert controlled by a controller; providing a list of temperature reduction measures including at least one of shutting down an application, reducing communication with an application server, shutting down a data communication session, entering a restricted communication state, shutting down a user interface device, reducing a user interface device capability, and reducing a device illumination level; and providing a power target for reducing the temperature in proximity to the energy storage device.
