Electricity-saving system and method for mobile phones

Abstract

The invention provides a mobile phone energy-conservation method which comprises the following steps: a standard brightness scope of the environment is set, and the set standard brightness scope of the environment comprises a minimum value and a maximum value; a camera is turned on; environmental brightness is measured by the camera; whether the measured environmental brightness is smaller than the minimum value of the standard brightness scope of the environment is determined; when the measured environmental brightness is smaller than the minimum value of the standard brightness scope of the environment, the keyboard light is turned on and the brightness of the liquid crystal module is reduced; when the measured environmental brightness is not smaller than the minimum value of the standard brightness scope of the environment, the keyboard light is turned off; whether the measured environmental brightness is larger than the maximum value of the standard brightness scope of the environment is determined; and when the measured environmental brightness is larger than the maximum value of the standard brightness scope of the environment, the brightness of the liquid crystal module is increased. The invention also provides a mobile phone energy-conservation system. The utilization of the method and the system can realize the automatic adjustment of the brightness of the LCM (liquid crystal module) to save power for a mobile phone.

Description

technical field

[0001] The invention relates to a power saving system and method for a handheld electronic device, in particular to a power saving system and method for a mobile phone. Background technique

[0002] Mobile phones have brought a lot of convenience to people's life and work communication. With the continuous development and progress of society and technology, mobile phones have also developed from traditional 1G (analog mobile phones) to 2G (GSM mobile phones, CDMA mobile phones and PHS), and from 2G to 3G. Simultaneously, along with the diversification of people's demand, the mobile phone of many different functions also appeared on the market, as: camera mobile phone, handwriting mobile phone and intelligent mobile phone etc. However, unlike the rapid development of mobile phones, the standby time of mobile phones has always been a bottleneck in the rapid development of mobile phones. The general standby time is only two or three days, which is obviously not...
