Abstract
Embodiments of the present invention provide methods and apparatuses for reducing power consumption for a mobile electronic device in order to extend battery life. In an embodiment, the mobile electronic device monitors a power level of the battery in the mobile electronic device, determines that the power level of the battery reaches a predetermined threshold, and based upon the determination, terminates a first launcher currently running on the mobile electronic device and activates a second launcher on the mobile electronic device. By activating the second launcher which has power saving features, the power consumption of the mobile electronic device is reduced and thus the battery life is extended while preserving the basic functions of the mobile device.
Claims22
A method performed by a mobile electronic device for power saving, the method comprising:
- activating a first launcher in a normal operating mode of the mobile electronic device to present a first set of application icons on a screen of the mobile electronic device;
- monitoring a power level of a battery powering the mobile electronic device;
- determining that the power level of the battery has reached a battery power level threshold;
- and
- based upon the determining, activating a second launcher different from the first launcher, wherein the first launcher and the second launcher are software programs that present links on the screen of the mobile electronic device for starting other software programs installed in the mobile electronic device, wherein the second launcher presents a second set of application icons on the screen of the mobile electronic device, and the application icons are for activating corresponding applications, wherein the second set contains fewer application icons as compared to the first set, and the second set includes a voice communication icon corresponding to a voice communication function and a text messaging icon corresponding to a text messaging function;
- disabling one or more applications on the mobile electronic device;
- disabling at least one of graphical or text notification on the screen of the mobile electronic device, wherein notifications for battery level, signal strength and clock remain on the screen;
- and displaying the voice communication icon and the text messaging icon, without displaying respective application icons for the disabled one or more applications on the screen of the mobile electronic device.
A mobile electronic device, comprising:
- a screen for displaying graphic information;
- a processor;
- and
- a memory coupled to the processor and storing programming for execution by the processor, wherein the processor being configured to execute the programming to perform operations of:
- activating a first launcher in a normal operating mode of the mobile electronic device to present a first set of application icons on a screen of the mobile electronic device;
- monitoring a power level of a battery powering the mobile electronic device;
- determining that the power level of the battery has reached a battery power level threshold;
- and
- based upon the determining, activating a second launcher different from the first launcher, wherein the first launcher and the second launcher are software programs that present links on the screen of the mobile electronic device for starting other software programs installed in the mobile electronic device, the second launcher presents a second set of application icons on the screen of the mobile electronic device, and the application icons are for activating corresponding applications, wherein the second set contains fewer application icons as compared to the first set, the second set includes a voice communication icon corresponding to a voice communication function and a text messaging icon corresponding to a text messaging function;
- disabling one or more applications on the mobile electronic device;
- disabling at least one of graphical or text notification on the screen of the mobile electronic device, wherein notifications for battery level, signal strength and clock remain on the screen;
- and displaying the voice communication icon and the text messaging icon, without displaying respective application icons for the disabled one or more applications on the screen of the mobile electronic device.
