Testing of Mobile Phone Battery Voltage

 

A  working battery voltage is approx. 3.7 volts DC,  below this voltage range the phone will not be power on. Checking the battery voltage by a digital multi-meter is so easy, just set  it to a DC range 20 volts then attach the both test probes to each corresponding polarity, Red probe to positive terminal, then black probe to negative battery terminal. Check the maximum battery voltage reading  3.7 volts. A battery voltage lower than 3.7 volts can power on the handsets but it shows Battery Low on a screen. A battery voltage lower than 2 to zero volts will hardly charge the phone and won't power up the phone.
