Very strange issues with wall charger
Hi,
I have an original wall charger and USB cable from Apple. A few days ago my iPhone 4S stopped charging with this wall charger and cable. If I use the same cable on the computer, it charges. My girlfriends iPhone is charging properly using this cable and wall charger. So the wall charger and cable is definitely ok. I also tried several other cables and wall chargers -> not charging with my iPhone. I checked with an amp-meter, the iPhone only gets 90mA.
Now the strange part:
If I replace the usb cable with a "dumb" cable which only has power lines (without data lines in it), the iPhone charges using my wall charger with 1A.
So the iPhone seems to have a problem with the USB data lines when connected to a wall charger. If the data lines are floating (not connected/shortened/no voltage divider), then it's charging.
Has anyone every had a similar issue? And do you know how to fix it?
PS: I already replaced the dock connector module and did several restores (incl. DFU).
Thanks
