Help! iPhone freezing, not responding, and turning itself on and off randomly.

Question

Over the last few days, my iPhone has been going crazy.  It all started when I turned on my phone one morning, and the ringer did not work.  It told me that headphones were in when I tried to turn the volume up.  Later in the day, I plugged my iPhone into my iHome.  It then "died" and would not turn on.  I tried everything (hard reboot, dfu mode, plugging in wall and computer, etc.) and nothing would turn it on.  The next day, I tried to turn it on, and to my surprise, it loaded the "low battery" icon.  i plugged it in, and it turned on.  It then randomly shut off ten minutes later.  It would not turn on, but it allowed me to put it into dfu mode.  I downloaded the os and attempted to restore the iPhone.  It shut itself off several times and took many attempts until I finally got it restored.  Now, it has been turning itself on and off.  I got it to turn on, and I used it until it froze.  It shut itself off and reboot.  It has continued to do this over and over again.  I am concerned because my iPhone is out of warranty, and I live far away from anywhere where I can get it fixed.  I have no idea what happened to my phone as I did not drop it or expose it to water.  Is there any way to fix this?  Is there a way to find what part may be broken?  If not, what is the cheapest and fastest method of fixing this and is anyone else having the same problems?  My phone is currently unusable because I can not turn it on (it only turns on randomly) and it freezes and shuts off a few minutes after it turns on.

Answer 1

Does it power back on by itself straight after turning off? If so I would probably suggest that either the charging port is faulty or maybe it is partially blocked with debris causing a possible short circuit across the pins. Try giving it a clean out first with something none metallic and might just do the trick.
