But the actual situation is that the power consumption units in the mobile terminal, whether it is the radio frequency part, including power amplifier, receiving unit, transmitting unit, etc., or the baseband part, including CPU, storage unit, LCM, etc., are basically based on power (W) To evaluate energy consumption, power P=current I×voltage U. From the discharge voltage curve of the battery, it can be seen that the voltage of the battery changes during the discharge process, especially when the battery is fully charged and the power is very small. It is very fast, so the current industry's current-based battery percentage display is flawed, and it also misleads consumers to some extent

The invention discloses an energy based electric quantity display method and device. The energy based electric quantity display method comprises the steps of fitting a battery discharge curve into a battery voltage curve combined by multiple segments of a straight line; acquiring the electric quantity and voltage at endpoints of each segment of the straight line; and calculating the energy percentage of discharge at any point according to the corresponding electric quantity and voltage at the endpoints of each segment of the straight line so as to display. According to the method, the stored energy and the service time of a battery at present can be reflected visually and accurately, and the user experience is enhanced.
Description
technical field [0001] The invention relates to the technical field of battery discharge, in particular to an energy-based power display method and device. Background technique [0002] At present, the power display of mobile terminals in the industry is basically based on the percentage display of the accumulated power of the current, so the unit is also the unit of milliampere-hour (mAh). Under certain usage conditions, users simply think that: every 1% The battery usage time is basically the same. But the actual situation is that the power consumption units in the mobile terminal, whether it is the radio frequency part, including power amplifier, receiving unit, transmitting unit, etc., or the baseband part, including CPU, storage unit, LCM, etc., are basically based on power (W) To evaluate energy consumption, power P=current I×voltage U. From the discharge voltage curve of the battery, it can be seen that the voltage of the battery changes during the discharge process,...
