Managing energy usage in mobile devices
First Claim
1. A method of managing power in a battery powered mobile device, comprising:
- measuring, with a battery monitoring circuit, one or more parameters indicative of a current state of a battery;
determining, with a processor, the current state of the battery by receiving data representing the measured one or more parameters;
calculating, with the processor, a battery power factor as a function of the received data;
comparing, with the processor, the battery power factor to a threshold;
when the battery power factor exceeds the threshold, identifying, with the processor, a system or process within the mobile device whose power consumption can be reduced; and
altering or disabling, with the processor, the identified system or process to reduce power consumption.

Abstract
A battery powered mobile device has battery monitoring circuit that measures one or more parameters indicative of a current state of the battery. A plurality of operational systems and processes form a part of the mobile device. A programmed processor is programmed to carry out a process that includes: determining a current state of the battery by receiving data representing the one or more parameters from the battery monitoring circuit indicative of the current state of the battery; calculating a battery power factor as a function of the parameter; comparing the battery power factor to a threshold; when the battery power factor exceeds the threshold, identifying a system or process within the mobile device whose power consumption can be reduced; and reducing the power consumption by altering or disabling the identified system or process.

19. A battery powered mobile device, comprising:
-
a battery; a battery monitoring circuit that measures battery temperature, battery terminal voltage and battery current draw as an indication of a current state of the battery; a plurality of operational systems and processes forming a part of the mobile device; a stored priority table that tabulates an assigned priority of the plurality of systems or processes that can be converted to a lower power consumption state; a programmed processor programmed to carry out a process comprising; determining a current state of the battery by receiving data representing the battery temperature, battery terminal voltage, and battery current draw; calculating a battery power factor by assigning a value to the current state of the battery temperature as T, assigning a value to the terminal voltage as V, assigning a value to the current draw as I, and computing the battery power factor as the sum of T, V and I; comparing the battery power factor to a threshold; when the battery power factor exceeds the threshold, identifying a system or process within the mobile device whose power consumption can be reduced by reference to the priority table and selecting a lowest priority system or process that can be converted to a lower power consumption state; and altering or disabling the identified system or process to reduce power consumption. - View Dependent Claims (20)
