I do not think it can measure either discharge or charge. The platform probably just guess, if USB connected it will always guess that it is charging 449 even if the current declines when the battery is almost full (CCCV). The same will happen with normal charger. For discharging it will probably be the same, depending on which peripherals that is on the platform is guessing the discharge current but for some reason they are not exposing that value.

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.
