Good news, you're likely wrong :)
Don't project the current draw when on the charger to when on the battery.
It's very normal for the charger portion of a PMIC to be extremely
in-efficient. I typically see less than 50% efficiency on chargers. The
power system will be optimized for running off the battery, but charger
power is usually seen as a free an infinite resource for the phone. It's not
worth the cost and area to optimize the power usage from the charger, so
it's almost never done.
