Then then judge this normal vector whether down (step S520) by operating system.Wherein, determining method vector whether down detailed step and previous embodiment is same or similar, so do not repeat them here.
Down the time, will further judge then whether this normal vector state down keeps one first special time (step S530) at the determining method vector.When normal vector is to be in state down and time of keeping when surpassing first special time, just control hand-hold electronic device and enter battery saving mode (step S540); Otherwise, if normal vector promptly departs from direction down before not reaching special time, then hand-hold electronic device can not imported battery saving mode, still keep normal operation pattern (step S550).
What deserves to be mentioned is that present embodiment also is included in after device enters battery saving mode, the step of opening device when the user desires to reuse device.Wherein, after device entered battery saving mode, the control of device was promptly transferred to embedded controller, and the gravity sensor of device still can continue to detect the normal vector on hand-hold electronic device plane at this moment.These detected normal vector data then can be sent to embedded controller, and whether depart from down direction (step S560) by embedded controller analysis and judgement normal vector, when if normal vector departs from down direction, then embedded controller departs from further determining method vector down, and whether the time of direction surpasses second special time (step S570), and when the time that normal vector departs from direction down surpasses second special time, just return back to normal operation pattern (step S580) by embedded controller control hand-hold electronic device.In addition, if the determining method vector does not depart from direction down, or it departs from when the time of direction does not surpass special time down, and then hand-hold electronic device is still kept battery saving mode (step S590).
In sum, the method for managing power supply of hand-hold electronic device of the present invention determines whether entering battery saving mode by the angle of putting that detects hand-hold electronic device, when the face down of hand-hold electronic device, judge that promptly the user wouldn't use, and import battery saving mode in good time to save electric power; Relatively, when downward direction is departed from the front of hand-hold electronic device, then represent the user to desire to reuse device, and device is returned back to the normal operation pattern.More an intuition and a power management approach easily can be provided in view of the above.
