Abstract

A wireless communication device and method adapted for temperature monitoring and warning is disclosed. In its simplest form, it can include: providing (510) 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 (520) if a temperature in proximity to the 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; and entering (540) the warning mode when in the warning operation temperature range. The warning mode can include a notification, banner or the like, to a user, to suggest that at least one active application be shut down.
