Battery testing mainly includes battery capacity, nominal, charge and discharge performance, high and low temperature performance, as well as some anti-overcharge and over-discharge capabilities and the ability to withstand vibration and shock.
The batteries made by regular manufacturers will generally have a higher capacity than the nominal ones, and generally leave room for 10 to 20 mAH .
1. Check the battery capacity with software for testing the battery capacity of your phone.
2. In the case of ensuring that the test process is constant current, select a resistor similar to the resistance of the mobile phone to be connected in series with the ammeter, and then discharge the fully charged (4.2V) battery until the end of 3.7V . Measure the current and record the time. If the recorded current is 200mA , the discharge time is 4 hours. Then the battery capacity is 200X4=800mAh .
3 , handed over to the professional testing department for testing.
