Abstract

The invention discloses an intelligent mobile phone power supply management module, which comprises a PM Daemon module, a PMComponent module and a power supply management chip, wherein the PM Daemon module is connected with the PMComponent module; after receiving an upper layer application, the PM Daemon module controls and schedules the PMComponent module, and at the same time, the PMComponent module provides a hardware control interface for the PM Daemon module; and the PMComponent module is also connected with the power supply management chip to control and manage the power supply management chip. The power supply management module of the invention prolongs standby time and prolongs average standby time by 23 percent, reduces the sleep current of a machine system to 1mA and prolongs the multimedia application and mobile phone call time by 20 percent.

Description

technical field [0001] The invention belongs to embedded mobile terminal equipment, in particular to a smart phone power management module. Background technique [0002] With the development of science and technology, human life is increasingly dependent on technology. Because modern people have a need for portable electrical appliances, portable technology is developing very rapidly. As a common portable electrical appliance, smart phones are used more and more widely. Smart phones have many functions. In addition to the traditional call function, they can also realize computer functions such as playing audio, video files, and surfing the Internet. Today's smart phones It's actually a small computer. However, if a smartphone is only used for calls, its 1000mAh battery can be used for an average of 200 to 300 minutes after being fully charged; if it is used for multimedia-related applications, such as playing videos, the battery can only be used for 120 to 240 minutes. Sma...
