The invention discloses a method and a system for indicating the service time of an intelligent phone battery by sensing a system context, belonging to the field of the application software of an embedded type system. The method of the invention comprises the following steps of: collecting and analyzing the electric quantity and time of a battery and the context attribute information of the system; establishing a model for the context attribute of the system and the discharge rate of the battery, and calculating the discharge rate of the battery in various contexts of the system according to the model for the context attribute of the system and the discharge rate of the battery; predicting the rest service time of the battery according to the discharge rate of the battery, and predicting the prolonged or shortened variation of the rest service time of the battery according to the discharge rate of the battery when the user changes the context attribute value of the system. The invention can indicate the rest service time of the battery on an intelligent phone and change the influence of the context attribute value of the system to the rest service time of the battery, so that the indication function of the electric quantity of the intelligent phone battery is more humanized and the prediction of the rest service time of the battery is more accurate; in addition, the invention has good marketing prospect and application value.
Description
technical field [0001] The invention relates to a mobile phone battery, in particular to a method and system for indicating the remaining usage time of a battery of a smart phone for sensing system context, and belongs to the field of embedded system application software. Background technique [0002] With the rapid development of computing power, storage capacity, and multimedia processing capabilities of embedded systems, smart phones can support more and more applications, and their functions are becoming more and more powerful, and they are developing in a diversified and personalized direction. However, the development of battery technology is very slow, and it is difficult to meet the power demand of smartphone devices. A major problem facing smartphones is that limited battery capacity limits the device's lifetime and user experience. In order to solve this problem, on the one hand, people research and develop various methods to reduce energy consumption and improve ...
