I want to ask, how to measure the shutdown current, kneel down and ask for details, such as measuring the battery voltage difference divided by the total resistance of the circuit.
What do you mean? I don't understand.
Do you want to test the turn-off current of battery-powered equipment?
Tell you what, I'll give you an example with my mobile phone.
First of all, you should prepare a regulated power supply (the one with current display). If you want high accuracy, you should prepare an ammeter.
The steps are as follows:
1) Adjust the regulated power supply to make the voltage reach 4.2V
2) Take out the battery and try to use the regulated power supply to power the mobile phone.
3) Try to turn it on, and then turn it off after success. At this time, the current seen by the regulated power supply is the value you want.
If the accuracy is improved, connect the ammeter in series with the test path.
