Return step 101.
In step 107, whether terminal judges battery is discharged to shutdown voltage.It is noted that being carried in this step
The shutdown voltage for arriving, be terminal preset a magnitude of voltage, for prompt terminal battery voltage have descended to battery should not be again
Continue the position (will shut down in the short time) of electric discharge.
If battery has been discharged to shutdown voltage, step 108 is entered；This is returned if battery is not also discharged to shutdown voltage
Step.
In step 108, whether the show value of terminal judges current battery charge is more than 0%, if current battery charge
Show value is more than 0%, then enter step 109.
In step 109, terminal deducts the second preset value on the show value of current battery charge every the default M seconds,
Until the show value of current battery charge reduces to 0%.
Similar with charging process, in order to slow down the charging and discharging curve of battery, in present embodiment, the second preset value and M
Ratio be less than or equal to 0.0001, wherein, M be more than 0.
In this step, the default M seconds are total discharge time/100, and the second preset value is 1%.It is worth mentioning
Be, as the total capacity of battery can become less and less with the use of battery, therefore, when detect battery fully charged after, eventually
