Abstract

The invention provides a method and device for displaying the electricity amount of a battery and an electronic device. The method includes the steps that an initial voltage value and an initial electricity amount value of the battery are obtained; after the battery is charged or discharged for preset time, the current voltage value and the current electricity amount value of the battery in the current state are obtained; if the current voltage value meets a first preset condition compared with the initial voltage value, and the current electricity amount value meets a second preset condition compared with the initial electricity amount value, the current voltage value and the current electricity amount value are displayed. According to correspondence relations between changes of the voltage and electricity amount of the battery in the processes of charging and discharging the battery, the electricity amount of the battery is obtained; under the condition that an electricity meter chip and other hardware circuits are not additionally arranged, the electricity amount of the battery is accurately calculated, the precious arrangement space for circuit boards inside terminal equipment is saved, furthermore, the cost is lowered, the freedom degree of hardware designing is increased, and product competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device and electronic equipment for displaying battery power. Background technique [0002] Smart terminal devices represented by mobile phones have become more and more popular. During the process of using them, users have also proposed more improvements in terms of industrial design, user interface design, application friendliness, operating system security and procedures, multimedia, and battery life. high demands. [0003] In terms of battery life, on the one hand, we need to reduce power consumption and improve battery life; on the other hand, we also need to accurately report the current battery life and time to users, so as to help users understand battery life in a timely and accurate manner. The power calculation is usually implemented using a fuel gauge chip. The basic principle is to obtain the battery power through voltage acquisition (VADC) and current ...
