Abstract

An embodiment in the invention discloses a method for determining a charging time. The method includes following steps: acquiring a present electric quantity L and a total electric quantity M of a battery during a charging process; if the present electric quantity L is no more than a preset electric quantity threshold value C, calculating a charging time t1 of a current-constant charging stage of the battery from the present electric quantity L to the electric quantity threshold value C and a charging time t2 of a voltage-constant charging stage of the battery from the electric quantity threshold value C to the total electric quantity M; and determining a required remaining time X for completing a charging process for the battery according to the charging time t1 of the current-constant charging stage and the charging time t2 of the voltage-constant charging stage. The embodiment in the invention also discloses a device for determining the charging time and an electronic device. By means of the method, the device and the electronic device, accuracy of calculation of the charging time of battery can be increased.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for determining charging time, and electronic equipment. Background technique [0002] Due to the requirements of portability and mobility, terminal devices such as mobile phones are usually powered by batteries. After the battery is used for a period of time, the user needs to charge the battery to meet the power supply demand. [0003] In the prior art, the terminal device can monitor the change information of the battery power locally, and the change information includes the current power information, for example: the last time the battery power was 20% of the total power, and the current power is 21% of the total power, then the calculation The charging time for a 1% change in power, and then roughly estimate the remaining time required to charge the battery from the current power to 100% of the total power by an equal ratio method. [0004] The mobile phone ba...
