Display packing is applied in terminal, as it is shown on figure 3, described information about power display packing comprises the following steps:
Step 301: in the first moment, the system that obtains is run duration, and is started sample rate current.
In the embodiment of the present invention, described terminal may is that the electronic equipments such as mobile phone, panel computer, notebook computer.Described
Electronic equipment has battery, is powered to electronic equipment by battery.As a example by terminal is as mobile phone, mobile phone is provided with electricity
Pond, the electricity of battery is the key factor affecting mobile phone continuation of the journey.In order to ensure the normal use of mobile phone, generally at mobile phone screen
Top shows the electricity of battery, and here, the electricity of battery refers to the electricity of remaining battery.In one embodiment, battery
Electricity can be shown by progress chart target form.In another embodiment, the electricity of battery can also pass through battery
The mode of electricity percentage ratio is shown, such as 90% electricity.
In the embodiment of the present invention, being provided with coulometer in terminal, coulometer, also known as ampere second meter, is programmable digital electricity
Table, uses advanced microprocessor to carry out Based Intelligent Control, to the signal inputted after calculation process, exports current battery charge
Equipment.
