Abstract

The embodiment of the invention discloses a power supply device and method for a terminal, relating to the technical field of communication and aiming at enhancing use experience of users for terminals. The power supply device comprises a detection unit, a voltage boost unit, a voltage acquisition unit and a battery unit, wherein the detection unit is used for detecting whether the voltage of the battery unit is lower than a preset working voltage; the voltage boost unit is used for booting the voltage of the battery unit and transmitting the boosted voltage to the voltage acquisition unit when the detection unit detects that the voltage of the battery unit is lower than the preset working voltage; and the voltage acquisition unit is used for regulating the voltage sourced from the voltage boost unit so as to acquire the power supply voltage of the terminal. The embodiment of the invention is mainly used in various terminals.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a terminal power supply device and method. Background technique [0002] At present, with the development of communication technology, mobile phones have become the most common mobile communication tools, bringing great convenience to people's lives. Generally, most mobile phones use lithium-ion batteries. In order to ensure the normal use of the mobile phone, when the voltage of the lithium-ion battery is lower than 3.5v, the mobile phone will send out a low battery alarm; when the voltage of the lithium-ion battery is lower than 3.3v, the mobile phone will automatically shut down. [0003] When the mobile phone is automatically shut down and the external charging device cannot be used to charge the mobile phone, it will bring a lot of inconvenience to people who are in urgent need of communicating with the outside world, thereby reducing people's experienc...
