IPhone 4 keeps turning off randomly.

Ever since I updated to iOS 5, my iPhone keeps turning off at random times. At first, it didn't happen too often, and I would be able to turn my phone back on without any problems. Now, it shuts off quite often to the point where I can barely use it. And very time I'd try to turn it back on, the Apple logo would appear like it's starting up normally and right when it's about to actually turn back on, it just shuts back off. The only time it's able to turn back on is if I plug it in. Any help/fixes to this problem? I tried doing hard resets, tried setting up the phone as new, deleted apps, etc...nothing has worked. Is anyone having the same problem??

Hi ManiPictures,
If your iPhone shuts down unexpectedly during use, I would suggest that you troubleshoot using the steps in this article -
If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support
As your iPhone's operating system is already up to date with iOS 8.1.1, follow the last instruction -
If you still see this issue after updating, contact Apple Support.
Thanks for using Apple Support Communities.

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 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.

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 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.

Hey MetalGuy75,

IPhone 4 turns off randomly and refused to turn on until 10 mins or so...

My iPhone 4 originally AT&T smart phone, is what I use on T-mobile as of right now. I have had it for just about two years now and I think it's coming to its last few days. It turns off randomly throughout the day and does not turn on right away when I push either other of the button (simultaneously or one at a time), until about 5-10+ minutes or so. It is very frustrating and I really do love apple products but I don't know, something is telling me to switch to android unless a miracle happens.
Thanks in advanced.

IPhone 4 turns off randomly, and doesn't start up unless its on the charger. Hard resetting it when its turned off doesn't turn it on either.

My iPhone 4 is running iOS 4.3.4 and it suddenly turns off randomly, usually when the batery is around 85% or so. When I try to turn it on the normal way or hard resetting it, it doesn't turn on. It only turns on when its connected to a charger, and the time and date resets to 7.30am, January 1st 1970. I have no idea why is this happening and how do I resolve this issue? I really don't want to go get it replaced as its too much of a hassle and Im leaving to another country in 2 days time..

It also starts charging at 70% or so when it turns on..

My iPhone 3gs turns off randomly (applecare sent it back as it was!)

Hi, had my iPhone 3Gs 32GB Black since about August 2009. From the outset it has turned off randomly ever few days or so, usually when I am in the middle of a call. I tried resetting the phone. Removing all the apps. etc. etc. but no luck.I stuck with it thinking that the problem would go away or that some future software update would fix the issue but also no luck.
So I took it into Movistar (the dealer for the phone here in Spain) a couple of weeks ago and they duly sent it off to Applecare for repair. Apparently you cannot do that yourself, it has to go through the store.
Anyway, got the phone back today with a really shoddy looking photocopy from AppleCare Service in Cork (Ireleand) saying that " their technicians could not find any problem with the phone..." blah blah blah. and that the problem should fixed by reset!
So what do I do now. I know that if they have not actually found the fault then the issue will persists. The Movistar sales woman said to just bring it back in that case and they would send it off to Apple again (for another two weeks...).
Is there any way I can contact Apple CAre direct about this? Anyone got any suggestions?
Cheers,
Tony

Thanks, but no Apple stores in Spain. Have to go through telco. Movistar. Will just send it back again for repair... see if they can fix it this time or give me a replacement.

IPhone 3G turns off randomly

Ok, firstly I know this topic has been coming up on the forum, but I haven't found any of the threads helpful or offering a clear solution so far.
I had my iPhone for 5 months and during that period I haven't installed any apps on it. Everything worked fine, no problems at all. Just recently I installed apps for the first time and it was fine for a while (2 weeks or so) but then it started turning off randomly. I can only hold in the sleep button until the apple logo comes up and it turns on again.
I figured it had something to to with the apps so I did a reset and only kept apps that 'seemed' to me safe to have (Facebook, Wordpress and Skype). But the problem still remains.
So here is my question, has anybody found a soild solution to this? Should I consider returning it? Can it be a hardware issue?
Thanks in advance for any help

You're welcome.
Does that mean that every time I add applications and this 'turning off' happens, I can't have any apps on my iPhone? (sadly that would defeat the purppose of haveing an iPhone to a large degree)
No. If this happens every time you add applications, there is something wrong with your iPhone. I suggested removing all 3rd party applications to see if the same occurs without any 3rd party applications installed. I ended my previous post with the following:
*I don't believe this will make any difference. _If an iPhone reset, a restoring the iPhone with iTunes from your iPhone's backup, and restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup does not resolve it, then your iPhone has a hardware issue._*

My iPhone 4 turns off randomly not completely turn off

Pls help my iPhone 4 turns off randomly

Clean iPhone charging port with clean dry toothbrush. See if better. If not and there is warranty or AppleCare make Genius reservation and take to Apple for resolution. If no Coverage, clean again with toothbrush and some Isopropyll Alcohol. See if better. If not you may need charging port assembly and/or battery replacement.

IPhone keep turning off my email notification

I've about 10 mailbox configured and iPhone are turning some banners alert, lock screen, etc for the notification off for random mailbox at random time. I turn them on and it happens over and over again. It might be iOS to fight annoying email notification but I've got important email comings in.

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!
