A charging method for a terminal battery and a mobile terminal

Abstract

The embodiment of the invention provides a terminal battery charging method and a mobile terminal. The method comprises steps: voltage of a rechargeable battery of the mobile terminal is charged to initial cutoff voltage and current of the rechargeable battery is charged to initial cutoff current; and if the charge and discharge cycle number of the rechargeable battery is larger than a preset cycle number threshold and the current state information of the rechargeable battery meets a first preset condition, the rechargeable battery is subjected to supplementary charge, and thus, the voltage ofthe rechargeable battery is charged to preset cutoff voltage and the current of the rechargeable battery is charged to preset cutoff current. In the embodiment of the invention, when the charge and discharge cycle number is judged to meet the preset cycle number threshold, the current state information of the rechargeable battery is judged to meet the first preset condition, the rechargeable battery is subjected to supplementary charge, and on the basis of ensuring the charge speed, insufficient charge caused by polarization of the battery in the later stage of use of the mobile terminal canbe effectively avoided, and the use experience of a user is further improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for charging a terminal battery and a mobile terminal. Background technique [0002] With the popularization of terminal equipment, especially more and more various application scenarios, the battery power consumption is getting faster and faster. Manufacturers can only passively request to increase the energy density of the battery or focus on the improvement of the charging speed to alleviate consumers' concerns about the battery. Anxiety about power consumption. [0003] Whether the existing terminal charging method is low-voltage direct charging, high-voltage charging or half-voltage charging, its essence is conventional constant-current constant-voltage charging or constant-current charging that increases the limit voltage of constant-current charging or simple constant-current charging. [0004] Due to the cost pressure, without increasing the output ...

Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide a terminal battery charging method and a mobile terminal to solve the problem of charging cut-off current due to charging cut-off current The increase of the battery makes the polarization of the battery in the later stage of the cycle increase greatly, resulting in a decrease in the battery charge rate, resulting in a decrease in the use time of the mobile terminal, which affects the user experience.
