Abstract
A method for efficient battery use begins by monitoring at least one output of the handheld device for an overload condition. The processing continues by monitoring a system voltage produced by a DC-to-DC converter for a system low voltage condition. The process continues by monitoring voltage of the battery for a battery low voltage condition. The processing then continues by enabling one of a plurality of fail-safe algorithms based on when one or more of the overload condition, the system low voltage condition, and/or the battery low voltage condition are detected.

31. An integrated circuit for use by a multifunction handheld device, the integrated circuit comprises:
-
a processing module;
a memory, operably coupled to the processing module, for storing a plurality of digitally formatted files, and that stores operational instructions that cause the processing module to;
receive a first digitally formatted file of the plurality of digitally formatted files from a host device when coupled to the host device via a host interface and store the first digitally formatted file in the memory, wherein the handheld device is powered by the host device when coupled to the host device via the host interface;
generate a second digitally formatted file of the plurality of digitally formatted files by digitally recording a voice sample and store the second digitally formatted file in the memory;
playback a selected one of the plurality of digitally formatted files, the playback including the generation of an audio output;
monitoring for a low voltage condition produced by a low battery voltage;
when the low voltage condition is detected, enabling a first fail safe algorithm to;
disable the audio output;
store settings corresponding to the selected one of the plurality of digitally formatted audio files; and
shutdown the multifunction handheld device;
wherein, when the battery is replaced and the handheld device is reactivated, the memory further stores operationally instructions that enable the playback of the selected one of the plurality of digitally formatted files to resume where the playback left off. - View Dependent Claims (32, 33, 34, 35)

45. A method for use in a multifunction handheld device, the method comprises:
-
receiving a first plurality of digitally formatted files from a host device when coupled to the host device via a host interface;
playing a selected one of the first plurality of digitally formatted files, the playing including generating an audio output;
monitoring for a low voltage condition produced by a low battery voltage;
when the low voltage condition is detected, enabling a first fail safe algorithm to;
disable the audio output;
store an audio setting corresponding to the playing of the audio output; and
shutdown the multifunction handheld device. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53)
