Ok, I am also able to read 449 mA for charging via USB. Just wondering how is the phone able to measure the charging current and not able to measure the discharge current.
For now I am planning to connect an external resistor and measure the discharge current. I think that's the way to only way to get the current values. Thanks for your inputs.
