but what i'm saying is that once those numbers go to zero, i can use the device for hours, and there is no drop. it just keeps pulling off the charger, while the battery numbers dont move at all. the result is that it trickle charges the battery while at the same time letting the phone run off the power cable, not the battery.
those zeros that show up are the draw on the battery. negative means its drawing current from the battery, positive means charging into the battery. the zeros that appear once it hits 100% and charger off message appears means that there's no battery drop after that.
