Iphone 4s suddenly stops charging via usb port?

One moment my phone would charge normally on my net book via usb please help!

Hm, is the iPhone still recognised in iTunes?

Also, have you tried using a different USB cord? Or plugging into a different port?

There's also a discussion on the apl forums about this issue: https://discussions.apple.com/...0&tstart=0

Hope this helps.

  • Why port forwarding on port 80? I have a foscam home security camera and it needs port forwarding on port 80 if I want to use my iphone to view it from outside. Surely enough, it works as soon as I open that port. But isn't port 80 open by default? Else how could I view http websites in the first place. I don't get it. It's already open so why open it again?
  • Regardimg charging iphone through laptop via USB cable? This is my issue. When I start my laptop (running Windows Vista), when I plug in my iPhone through USB, I can charge it and access it through iTunes as it should be but as soon as I unplug it, when I replug it the laptop doesn't recognize it and it won't charge at all. When I access device manager, I see a little triangle with an exclamation mark saying error code 10. Any idea how I can fix this issue?
  • Iphone stops charging as soon as it turns on? I've been having issues with my iPhone 4 (iOS7) lately. When it runs out of battery, I plug it into charge, and as soon as it turns on, it stops charging. As soon as it gets to around 4%, it just starts going down again, even when it is still plugged in.
