Abstract

The invention discloses a mobile communication terminal and a double-battery charge and power supply switching method thereof. The main board of the terminal is provided with two battery interfaces and a charge and power supply circuit connected with the two battery interfaces. After the start-up of the terminal, the switching method comprises the following steps that: S1, a battery A supplies power, a battery B is idle and the voltages of the two batteries are recorded; S2, when the voltage of the battery A fails to meet power supply conditions, whether a charger is plugged in is judged; S3,when the charger is plugged in, the battery A supplies power while being charged, and the battery B is still keep idle; S4, when the battery A is fully charged and the battery B is undercharged, the battery A supplies power and the battery B is charged; and S5, when both the batteries are fully charged, the step S1 is returned to. The mobile communication terminal uses double batteries for charge and power supply, thereby meeting requirements on large capacity of mobile phone batteries. In addition, immediate switching is performed to allow another battery to supply power to ensure the continuity of the power supply of a mobile phone in case of accidents, for example, a battery is removed and software receives interruption sent by the system.

Description

technical field [0001] The invention relates to the communication field, in particular to a mobile communication terminal and a method for switching between charging and supplying power from double batteries. Background technique [0002] The functions of current mobile communication terminals (such as mobile phones) are increasingly extensive. Many multimedia technologies such as ringtones, MP3, cameras, and FM frequency modulation have been applied to most mobile phone products, and the addition of various additional functions has become an inevitable trend. And various functions and additional devices must increase the demand for the battery capacity of the mobile phone, but most of the mobile phones in the prior art are powered by a single battery, so it is difficult to solve the problem of large demand for the battery capacity of the mobile phone. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the mobile phone ba...
