Method for displaying residual battery electricity quantity of mobile terminal

Abstract

The invention discloses a method for displaying the residual battery electricity quantity of a mobile terminal, which comprises the steps of detecting the electricity quantity, comparing the electricity quantity and updating and displaying an electricity-quantity value, wherein the electricity quantity is continuously detected, and when the currently-calculated residual battery electricity-quantity value is continuously greater than or smaller than the currently-displayed electricity-quantity value for certain times, the currently-displayed electricity-quantity value is then updated. In the invention, by utilizing two charging and standby voltage-electricity-quantity curves and combining the comparison of the currently-calculated electricity-quantity value with the currently-displayed electricity-quantity value for many times, the currently-displayed electricity-quantity value is updated step by step, the problem of electricity-quantity jumping is solved, and the electricity quantity can be accurately displayed.

Description

technical field [0001] The invention relates to the display field of remaining power of a rechargeable battery of a mobile terminal, in particular to a calculation method for calculating the remaining power of a rechargeable battery through battery voltage. Background technique [0002] With the development of modern technology, portable devices such as mobile phones, PADs, and notebooks can be seen everywhere. Portable products provide more and more functions, and people need to accurately monitor battery power in order to manage power reasonably. [0003] With the help of battery power detection technology, the battery life of mobile devices can be accurately measured. It is not uncommon in mobile terminals and notebook computers. [0004] Currently, most handheld devices estimate the corresponding remaining battery power by measuring the battery voltage. The corresponding relationship between the system battery voltage and capacity is obtained to obtain the grid bench...

Problems solved by technology

This way of displaying the battery level is too rough, and the display is often inaccurate, especially for batteries that have been used for a long time, the grid display is full, but it cannot be used for enough time. To meet the user's precise monitoring requirements for power, users need to know the percentage of remaining power more accurately

[0005] Moreover, after the battery is loaded, the battery voltage will also fluctuate as the load changes. If the displayed power value is completely converted according to the voltage value, there will be large fluctuations in the power value, which will affect the user's monitoring of the battery power.
