I want to make charger for the IPhone to display the battery status on digital voltmeter how much percent or volt battery charge.
I already made 12v, 9v, 4.5v power input to charge the iPhone.
I can see the voltage input from the input power and amperage of the charger on the voltmeter, amperage digital display but how to monitor the actual iPhone battery status?
I know that I can just watch the screen of the iPhone to check the battery status but I would like to try to make the above possible too.
If you know how, then please reply with schematic.
Thanks.

You can't, except by using the iphone's own battery status notification.

 

I think we already covered this thoroughly in the previous thread, noted by spinnaker in post #2.
