Remember, Keep probes touched until you see a stable reading on the reading scale of the meter. If the reading scale on the meter shows more than 3.70 then the battery is fully charged. And if it is less than 3.70 you will have to charge the battery with a charger. after charging for a long time with the phone original charger, if the battery still showing the same volt on the meter, then the battery is faulty. your phone will not switch on. You will need to buy a new battery because it is not repairable.
Note: If the battery is drained and showing 0 voltage or say less than 2.9, you can repair it with the battery booster.
