Handhold electronic device and power supply management method

Abstract

The invention discloses a method for managing electrical power source of an hand-held type electron device which detects normal vector of the hand-held electron device plane by using a G-sensor and judges whether the normal vector being downwards, when the normal vector is downwards, the hand-held electron device is controlled to enter a power saving mode. In the power saving mode, the G-sensor still detects normal vector continuously, when normal vector deviates downward direction, the hand-held electron device is controlled to recover to normal operating mode. So, the hand-held electron device is controlled to enter power saving mode suitably by putting state of the device without intricacy program such as selecting operating, and the electrical power source management approach more intuitive and convenient.

Description

technical field [0001] The present invention relates to a power management method, and in particular to a power management method using a gravity sensor. Background technique [0002] With the rapid development of technology, the functions provided by handheld electronic devices such as mobile phones, personal digital assistants, and notebook computers are also becoming more and more diversified. E-mail has also become one of the indispensable functions of current handheld electronic devices. Various functions can not only bring convenience to people's life, but also can be used as a tool for daily leisure and entertainment, which also makes handheld electronic devices one of the most popular high-tech electronic products nowadays. [0003] Most of the handheld electronic devices are used outdoors, and when the external power supply cannot be connected, the electric power of the entire handheld electronic device can only be supplied by the battery installed in it. It can b...

Problems solved by technology

[0004] However, as far as the power-saving function of the current handheld electronic device is concerned, it is necessary to rely on the user to set a preset period of time. will enter power saving mode

This method needs to be maintained for a period of time before entering the power saving mode, which still consumes a lot of power

In addition, in addition to the above-mentioned way of preset time, when the user stops using the handheld electronic device, he can manually search and enter the power-saving mode through layer-by-layer menu selection. However, this manual method not only A waste of time, relatively complex actions often make users feel troublesome and unwilling to perform them, and in the end there is still no way to achieve the effect of saving power
