How Many Volts In A Cell Phone Battery. Remove your battery from your phone and lay it on a flat surface. So the C of a 2Ah battery is 2AThe amount of current a battery likes to have drawn from it is measured in CThe higher the C the more current you can draw from the battery without exhausting it prematurely.

When a battery is fully charged the capacity is the amount of power it contains. However they have higher energy density compared to Li-Polymer. This is my Galaxy S3 battery used daily for over a year and a half.
Thanks for the A2A Andrei.
Once you hit 34V the battery is dead and at 30V the cutoff circuitry disconnects the battery more on that later. Fast charging a battery isnt just a case of throwing as much voltage and current at a battery as possible. Bear with me here Just like your heart supplies oxygen-rich blood to the rest of your body your smartphones battery pumps nutritious electrical energy to every part of the device keeping it healthy and functioning. Batteries of the same type will often be rated by the amount of current they can output over time.
