My iPhone 4S was about to die as I got home, I plugged it in at 1% and it did not charge. It then died a moment later and showed the charge alert screen (http://www.lionandbull.com/wp-content/uploads/2009/10/apple_iphone_will_not_char ge.jpg), I plugged it in with various chargers and it no longer worked.

Failing this, I plugged my phone into my macbook pro and got the alert 'Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled'

I promptly disconnected my phone from the laptop not wanting to cause further damage.

As my phone had been unresponsive for an hour I left it alone for several hours and when I returned and pushed the home screen it showed the charge alert and I plugged it in and it began to charge (I got excited) so I left the room and walked back 20 minutes later expecting some charge and the iPhone was unresponsive again with a blank screen.

I have tried resetting the phone and followed other online tutorials.

It's very important for my business that phone contact is readily available, so any advice?

    Hello ilycharl,


    I would be concerned too if my iPhone was not powering on.  I recommend following the steps below to address an issue like this:

    Will not turn on, will not turn on unless connected to power, or unexpected power off

    1. Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    2. Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    4. After at least 15 minutes, if:
      • The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen HT1650_2.jpg. Then unplug the phone from power. If it immediately turns off, seek service.
      • The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
      • Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    5. If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
      • If the display turns on, go to step 4.
      • If the display remains black, go to next step.
    6. Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
