Problems solved by technology

When the power consumption of the terminal system is relatively large, the voltage division of the internal resistance of the battery will be relatively large, so that the external power supply voltage of the battery will be relatively small, and the power management circuit of the terminal generally has a minimum operating voltage. When the external power supply voltage is lower than the minimum working voltage, the terminal system will directly power off
[0003] At present, the existing technology mainly prevents the terminal from power-down by prohibiting the opening of high-power consumption applications or setting the power-saving mode when the terminal power is relatively low. Reducing the power consumption of the terminal does not effectively prevent the terminal system from powering down

Abstract

Embodiments of the invention disclose a terminal power failure prevention method and a terminal. The method comprises the following steps of: obtaining a current value of the terminal and an output voltage value of a terminal battery in real time; and if the current value is not smaller than a preset current threshold value or the output voltage value is smaller than a preset voltage threshold value, adjusting a CPU running state of the terminal so as to control the terminal to enter an anti- power failure mode. According to the method disclosed by the embodiments of the invention, the current value of the terminal and the output voltage value of the terminal battery are obtained, the current value and the output voltage values are compared with the preset threshold values, and the CPU running state of the terminal is adjusted when the current value is smaller than the preset current threshold value or the output voltage value is smaller than the preset voltage threshold value, so as to control the terminal to enter the anti-power failure mode, so that the terminal is effectively prevented from power failure when the battery voltage is relatively low.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for preventing a terminal from power-down and a terminal. Background technique [0002] With the enhancement of the performance of the terminal processor, the power consumption of the terminal battery is also increasing. For example, the mainstream Qualcomm 8976 platform in the existing market has a single A72 processor with a full load power consumption of 2000mw, and the power consumption of four A72 It is possible to reach 8000mw. In addition, the terminal battery has internal resistance, and the size of the internal resistance has a certain relationship with the battery voltage. The greater the internal resistance, the lower the battery voltage. When the power consumption of the terminal system is relatively large, the voltage division of the internal resistance of the battery will be relatively large, so that the external power supply voltage of the battery wil...
