Us we knew battery consumption has become a very common problem in today’s cell phones and smartphones. It’s easy to test voltage on any phone battery with the help of the analog and digital multimeter. in electronics, the symbol V is the unit of voltage. The method of checking a phone battery is the same for all brands and models Micromax mobile, iPod classic, iPhone, Sony Xperia, Huawei Smartphone, HTC new phone, Motorola, Lenovo, LG, ZTE Nubia, BlackBerry, Nokia 6, etc.
Guide To Check Battery with the Digital Multimeter

| How do you test a phone battery |
Carefully remove the battery from the phone. you can read battery voltage on the label of the battery. Most feature phones and smartphone batteries are 3.7V or 3.8Volts. Now find the digital multimeter DC Volt setting on the meter measurement scale. It may be indicated with DCV. In DCV (DC Voltage) there will be many settings like 2V, 20V, 200V, 1000V. Keep the setting on 10V or 20V in a multimeter. Now follow the picture below to touch the probe of the multimeter on the terminal of the battery.

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.

You can see in the picture a plus and minus point you can place the black probe and the red probe here, which basically can be connected to a phone battery and boost the battery.
