Problems solved by technology

[0004] However, using the above method to measure the battery power of a mobile phone, under the same power condition, the power actually measured by the mobile phone at different stages of realizing various functions (that is, various application scenarios) is different from the power measured by the mobile phone in the standby state. This will cause users to misjudge the power of the mobile phone and affect the actual usage time of the mobile phone battery.

Abstract

The invention discloses a method and a device for measuring the electric quantity of a mobile phone battery. The method comprises the following steps of: measuring the voltages of the battery in real time at one stage of an application scene; compensating the voltage measured in real time by using a voltage compensation value corresponding to the stage; and determining the electric quantity of the battery according to the compensated voltage. By adopting the invention, the effect of accurately measuring the electric quantity of the mobile phone battery is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for measuring battery power of a mobile phone. Background technique [0002] With the rapid development of communication technology, mobile phones have gradually developed into comprehensive electronic products integrating various functions such as calling, playing music, video, taking pictures, videographing and surfing the Internet. At present, most mobile phones use lithium-ion batteries for power supply, and the increase in mobile phone functions makes the output current situation in various application scenarios more and more complicated. When the mobile phone is operating with a large current, the battery voltage will change with the fluctuation of the output current. The general rule is: the output current is large, the output voltage is low, and the output current is low, the output voltage is slightly higher. [0003] In the related art, the method of mea...
