I would be concerned too if my iPhone was not charging. Thank you for providing all the information with the steps you have tried. I found an article with a few more steps that might help with charging issues. You can skip any steps you have already taken:
Will not turn on, will not turn on unless connected to power, or unexpected power off
- 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.
- Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
- Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
- 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 . 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.
- 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.
- 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.
- If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

hey i have the same problem, but not the egsact. well this is the story, when i was leaving out my house i realised it was raining so i put my phone in my pocket, and then when i came back home it was wet and when the battary went it wouldnt turn on, so when i charged it, i soaked it in rice for 24 hours and i took it out when the next day it wouldnt turn on, and the most worse part is my iphone is cracked and my top button wont work, what shall i do?
in case of ios 7 u should charge ur phone in off mode. 1st u have to switch off ur phone. As your phone started to switch off at that instant put it on charge (once your phone switches off completely then it will be switched on upon connecting to charger and will fail to charge thats why you should connect charger at the time when your phone is switching off). wait about 2-3 hours then disconnect charger and switch it on, it will be 100% charged.
It sounds like your docking connector may be defective, preventing your phone from pulling a charge.
I had the same problem. Symptoms: Black screen except when I pressed the sleep button, at which time I would see the red battery / lightening bolt icon. It would flash 3 times and then the screen would go blank. I tried the wall outlet, the USB connection to the computer, different cables, etc.
The Genius Bar used their multimeter to tell me the phone wasn't working and then offered to sell me a new phone for $149. I went to a non-Apple repair shop where they diagnosed the problem as tarnished pins in the docking connector and fixed it in 30 minutes for $49.
