Im testing an iphone 5s along with a 5c.
After hooking the DCPS to the phone via battery terminal on the logic board, and i get the voltage i set it to on vcc main 3.9v. Why dont i see any amperage draw from the board?
This is hooking up the logic board only… when i hook up the logic board through the charge port i get 0.7 ma draw.
Es esta una buena pregunta?

That ia a normal reading
When you turn on the phone then you see the current has it boots up

So i cant read output voltages at Chestnut like 6v0 boost, until i power on the phone? But how will i measure with the multimeter if the logic board is in the housing connected to the power flex?
remove the logic board from housing you can jump the power button connectors on the logic board itself. Another way is to connect an know good charging dock connector and do a promp to boot
