What is the minimum current required to charge a smartphone battery?
This would have C = 1500 mA = max charge current. The phone will charge the battery either at C if ample energy is available or at the lower available rate until a predefined battery voltage is reached (usually 4.2V). It will then usually change to a constant voltage mode and the current will decrease with time under battery chemistry control.
amperage
I have always been confused when it came to how much charge does a battery charge. Let''s say, a phone battery: It says 1900 mAh @3.7 v. Now i know it goes up to 4.2v, but those 1900 mAh are available in the 2.5v ( cut off voltage i think) - 4.2v area or the 1900mAh are available in the entire 0v-4.2v, meaning that some of the battery s energy remains unused, right?
