Power saving method for handheld mobile electronic device and device using the same

摘要

The present disclosure proposes a power saving technique to be used by a handheld mobile electronic device. In particular, the handheld mobile electronic device would execute functions including determining a tilting angle of the handheld mobile electronic device above and relative to a level surface by using a sensor, determining whether the tilting angle exceeds a first angle threshold and falls below a second angle threshold, using a first counting threshold when the tilting angle is above the first angle threshold and is below the second angle threshold, using a second counting threshold which is less than the first counting threshold when the tilting angle falls below the first angle threshold or exceeds the second angle threshold, and darkening a touch screen of the handheld mobile electronic device when the handheld mobile electronic does not receive an input within the first counting threshold or the second counting threshold.

1. A power saving method to be used by a handheld mobile electronic device with a touch screen comprising:
determining whether any touch input is received within a second counting threshold; in response to not receiving any touch input within the second counting threshold:
determining a tilting angle of the handheld mobile electronic device above and relative to a level surface by using a sensor;determining whether the tilting angle exceeds a first angle threshold and falls below a second angle threshold;using a first counting threshold and entering a reading mode when the tilting angle is above the first angle threshold and is below the second angle threshold, wherein in the reading mode, the handheld mobile electronic device does not darken or turn off the touch screen;using the second counting threshold which is less than the first counting threshold when the tilting angle falls below the first angle threshold or exceeds the second angle threshold;darkening the touch screen of the handheld mobile electronic device in response to the handheld mobile electronic using the first counting threshold but does not receive any touch input within the first counting threshold; anddarkening the touch screen of the handheld mobile electronic device in response to the handheld mobile device using the second counting threshold but does not receiving any touch input within the second counting threshold; and using the first counting threshold when the handheld mobile electronic device is in a landscape orientation or in a right side up portrait orientation such that an speaker which is native to the handheld mobile electronic device is situated higher than a microphone which is native to the handheld mobile electronic device.
