iphone 4 turns off randomly and unable to turn it on without connecting to charger or PC

Hey Tiffy6996!
I have an article here for you that describes this issue and can help you troubleshoot the issue a little further:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/ts2802
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 LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 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.
Thanks for coming to the Apple Support Communities!
Cheers,
Braden

My iPhone 4 shut off randomly and wont turn back on.

Well I was texting on my iPhone 4 and then when I went to look and see if the person had replied my phone was off! I tried holding the on/off button and nothing happened. Why is it doing this?? I have had it for about a month and idk if the color makes a difference but its white and yes I do have a heavy duty case on it. It has not been dropped in forever too. Thanks

I got it to turn on looking at some other posts.. Press the home and wake button at the same time while plugged in the computer for 10 seconds works

Wife's iPhone keeps shutting off randomly and does it even when on calls, restarts and has a dark line in center of the screen then the apple logo. At times it does it several times or won't power up, and the iPhone4 is only five months old. What do we do

Have an iPhone 4 that is now shutting off randomly including during calls. The iPhone is roughly about five months old. When the iPhone shuts down and tries to restart it usually take two or three times before it stays on, but when it does it sometimes has a dark line down the center and shuts off. Not very happy about the iPhone doing this. The store we had purchased the iPhone 4 from suggested that we contact Apple to see about a replacement, or send it away for service. As you can tell we are not happy at this point since the iPhone is crucial part of our day for work and family. What should we do at this point?

Thanks for the suggestions!
Except I tried all those before I even made this topic lol, but thanks!
I Already popped out the Sim Card & let my phone sit without it for a few minutes then put it back in. Sometimes it will work again & it will say it recognizes the SIM Card but more times then not it still says it cant recognize it! So I have to take it out & reinsert it multiple times.
& I have done a complete restore 2 times & a back up restore 3 times. Nothing seems to be working.
I am planning on going to the Apple Store this week, wish me luck!
But keep the suggestions coming if you have any, I'd appreciate it!

HT4528 My Iphone 4 shut off randomly and it was charged and it wont turn back on. My power button is broken though so I cant restart it. Help?

If it will not power on by doing a reset, take the device to Apple for evaluation and possible replacement.

even tried to hold down the home button + the power button

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.

Iphone 4 shut off randomly and won't come back on

I was out yesterday and I put my Iphone 4 in my pocket, the battery was on %70 and I took it back out to make a phone call and it must have shut it self off, I tried turning it back on and it wouldn't work. I've tried pressing the home and lock button but that doesn't work either, I've plugged it in to my computer and it;s no responce? The phone is cracked, and I've had it over a year.

Plug it into a wall outlet for at least 30 minutes, then try resetting it, again: Press the Sleep/Wake button & Home button at the same time, keep pressing until you see the Apple logo, then release.
If that doesn't work, make an appointment at any Apple store.

My iPhone 5s turns off randomly and won't turn back on

Yesterday my iphone just shut off randomly even after being charged at 100%. I gave it a hard reset three times and it finally turned back on. But today it blanked out again and every time I try to turn it on the apple icon pops up but then disappears. The screen goes black and nothing happens. I've tried the hard reset and that doesn't work, I've even tried holding down all four buttons and it still doesn't work.

Iphone 4 turns off randomly and won't turn back on unless it's plugged in

Iphone 4 turns off randomly and won't turn back on unless it's plugged in.
Has anyone had this problem?
If I leave the phone (thus not doing anything to it) for an extended period of time say 2 hrs. It will have turned off and you can't turn it back on unless you plug it in, but it's got heaps of "Battery" left.
Ever so often it will turn off randomly as well, and can't turn it on again.

If your iPhone is powering off, this is not normal.
Try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup. If no change after doing so, your iPhone has a hardware problem. The iPhone includes a one year warranty.

My iphone shuts off randomly and the button is too sensitive. Like I don't even press the lock button and it shuts off. This happened after the 7.1 update. It's on the iphone 5.

My iphone shuts off randomly and the button is too sensitive. Like I don't even press the lock button and it shuts off. Also when my finger barely rubs over the lock button, it shuts off too. This happened after the 7.1 update. It's on the iphone 5. Someone help me. I just want to fix this. Maybe if it's possible I can disable the lock button.

The lock button does not turn OFF the iPhone. It will give you a screen with the option to turn OFF the iPhone. Possibly the battery is faulty. Make Genius reservation and take iPhone to Apple store for free battery diagnostic testing and evaluation.

My iPod shut off randomly and will no longer turn back on. I plugged it in to charge it, but after several hours it will not turn back on. What should I do?

My iPod turn off randomly. I plugged it in to the charger, and after several hours, it still will not turn on. I even plugged it into my computer and pulled up iTunes, where it showed up on the screen as plugged in, but still it will not turn back on. Any suggestions on what I should do?

- First try resetting the iPOd:
Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears
- Next try restoring the iPod via iTunes, first from backup and if still problem to factory defaults/new iPod.

I have the Iphone 5, and it shuts off randomly and the screen glitches. I have taken it into verizon and had it reset but the problem still continues. Is the only way to fix the problem to get a new phone?

Is the only way to fix the problem to get a new phone? Also, why is it if I do need a new phone I can only get a refurbished one when I am paying insurance every month?

If the issue persists, take the device to Apple for evaluation.

IPhone 6 shutting off randomly

My iPhone 6 shuts off randomly after using the camera or camera apps and during texts. It also needs to be plugged in while it still has 28% battery left. Anyone else? I restored and activated as new without any resolution to the problem. I am being told it's probably "an underlying hardware problem." Not thrilled.

To rule out a software issue, set it up as new device without using the latest backup, explained here:
iOS: How to back up your data and set up your device as a new device
If still problems after that, get it serviced:
