The time cycle of the resources occupation rate of system, the setting can be 10 seconds.That is, every 10 seconds, a moment t is recorded, and remember
Record measures the charging current value corresponding with the moment t of gained and the current value of the mobile terminal, forms the charging electricity
Stream file and the electric current file.
S103：By in the test electric current file, test current value corresponding with the moment t subtracts the charging electricity
In stream file, charging current value corresponding with the moment t, the acquisition mobile terminal corresponding with the moment t is practical to disappear
Power consumption flow valuve.
Specifically, the charging time in the charging current file and the testing time in the test electric current file
With according to determination at the time of the computer and mobile terminal progress charging connection.That is, when the computer and the shifting
When dynamic terminal is connected and is started to charge up, start recording charging time and testing time.In this way, the charging current file with it is described
Testing electric current file has unified time parameter standard.Such as：Determine that the mobile terminal is real when charging starts 5 seconds latter
The current value of border consumption, it is only necessary to which the test current value after starting to charge up the computer 5 seconds to the mobile terminal subtracts
Charging current value at this time, you can obtain.
