how can i charge the iPhone 6 battery using a dc power supply? if it’s possible then what pins do i connect the wires to and what volt/amps to set? and also is it possible to connect the iPhone to the dc power supply directly? and if so what pins do i connect the wires to and what volt/amps to set? thanks

Nadav, not quite sure why you would even try to attempt this. It could be somewhat disastrous to your battery or even your phone, since I am not sure how you want to do this. Anyhow, you will have to place + from the charger to + on the battery, as well as - to - .Your battery is a 3.8V so anything between 4V to 5V and~1A will work. Watch for over charging since you are taking the battery out of a safe circuitry. This image

from here shows the polarity on the logic board connector. Now you just have to mirror it for your battery connector. Again, not sure why you are planning this and I’d think twice about it:-)

i think it goes like this

Hello recalls that the charger that cell are typically brings direct current (the receive AC and converts it to DC) then any cell phone charger so you can charge, then here should see the amp, usually the cases are to charge 1 or 1.5 amp, it is best not to pass these amp so that the battery is not damaged !! I hope I have helped you, greetings!

apple‘s charger output is 5V 1A, so you can set the output dc for the 5V1A,and then charge the iphone。

To test where the negative and positive cables go use a multimeter to see how much voltage is coming out and if the number is positive the negative cable is on the negative and positive so forth, but if it is a negative number switch the cables to correct the orientation.
