HT201210 why does my phone keeps turning on and off by itself ?

Hi, my phone is been acting weird. My phone keeps turning on and off by itself and it frezzes. What should i do ?

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Why does my phone keep turning on and off repeatedly?

My phone was acting up so I turned it off and when I turned it back on it seemed to start normally but then it started the spinning screen for about 3 minutes, then a second of blue screen and started back up and just keeps doing that. It never properly turns on. I had to hold the home button and power button until it stopped. I did try to do a hard reset but that didn't work either.

Hi, my phone keeps turning on and off and won't charge

Hello Guerlyne18,
If your iPhone is sporadically shutting off and having issues charging I would suggest following the steps in the following article, including restoring and setting up as new.
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.
If necessary, you may need to contact Apple support is the issues continues after restore.
Issue not resolved
My issue is still not resolved. What do I do next?
Contact Apple Support.
Thanks for reaching out,

Try this. It worked for a few users after a drop.
Turn the iPad over and give it a very HARD slap on the back. May take several slaps.

My phone keeps turning on and offf

Hey johneigh1!
A power cycling phone sure can get old really fast so please know I'm ready to find the perfect solution to keep it on until you say otherwise. At this point, I'm very glad to know that you've gone through with some troubleshooting including a master reset but I've got an idea for something else we can try that should help.
Have you tried putting your phone into safe mode http://vz.to/ruJiUa ? This will allow us to isolate the issue to either the device itself or potentially an application. Please try this tactic and let us know how it responds. If all goes well while in safe mode, there may be an app that we'll want to get rid of.

My phone keeps turning on and off..

I have tried connecting it to itunes and it reconizes the phone but still continues to turn off and on every 2 or 3 seconds... anyone have this happen to them?

Have you tried restoring your device with iTunes? Before restoring,make sure to backup everything on your device.
If you do not know how to restore an iPhone, read this:
http://support.apple.com/kb/ht1414
After you restore, if the problem persists, and your phone keeps turning itself off, that means that there is a problem with your iphones logic board or battery. If thats the case, take your phone to an apple store and have them take a look. Hope I helped. Cheers

Attempted to update iOS 6 to iphone 3GS. Install froze, turned phone off, now phone keeps turning on and off.

How the heck do I get this thing to restore?
I was updating the iOS when it froze. Did nothing for hours. So I turned the phone off. When I went to turn it on again, the apple logo showed up and then the phone kept going back and forth between a black screen and the apple logo. Is there anyway to get this thing to respond and go back to iOS 5?

iPhones don't take baths too well. You can do what the other responder suggested and put it in rice for a few days, but this usually doesn't work too well. Here in the US Apple has an out of warranty replacement policy for situations like this. You might want to check on the policy in the UK, but I'm betting it's pretty much the same. Here in the US, they'll give us a replacement phone for the subsidized price we paid when new. For example, a 16GB iP4 costs $199 and we are tied to a two year contract with AT&T. So, when a phone goes for an unplanned swim, Apple will let us purchase a replacement phone for the same price. Good luck.......

HT201263 Phone keeps turning on and off

I tried to reset my iphone to factory reset, I have perform all the troubleshooting and still don't have any results.

Try resetting...
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.

Why does my phone keep popping up messages "This cable or accessory is not certified and may not work reliably with this iphone" when there is no cable connected?

Why does my phone keep popping up messages "This cable or accessory is not certified and may not work reliably with this iphone" when there is no cable connected? This has been happening since IOS7 was installed and has become worse with 7.1. I have reset the phone several times with no change.The phone charges properly & I have never used anything but an Apple Lightning cable.

I already cleaned the port with compressed air before submitting the problem. I since cleaned it with a toothpick and dug out some more lint. this seems to have just about fixed the problem since I have only had the error pop up 3 times since then and i was getting the error constantly before.

Why does my iphone 3gs keep turning on and off

i need help my iphone 3gs keeps turning on and off and it has a charged battery. ive tried multiple chargers but none of them work. and when i conect it to itunes it doesnt even read my device. what can i do?

After forgetting the password for my iPhone, I am trying to restore it through iTunes, however, during the process, the phone keeps turning on and asking for the password, thus canceling the process. Any advice?

Yes, you will still get the prompt.
I meant reset then try the recovery mode restore again.
You can also try DFU Mode.
DFU (Device Firmware Update) Mode is different than Recovery Mode.
DFU Mode is a special mode where the device can still interface with iTunes, yet it does not load the iBoot bootloader.
DFU Mode:
Plug your device into your computer.
Turn off the device.
Hold the Power button for 3 seconds
Hold the Home button without releasing the Power button for 10 seconds
Release the Power Button but keep holding the Home button
Keep holding the Home button until you are alerted by iTunes saying that it has detected a device in Recovery Mode
NOTE: Make sure the device screen is blank and no logos are present. Be patient, it make take several trys.

After the new update, why does my Bluetooth keep turning itself on? I keep turning it off, but it still finds a way to turn itself back on

After the new update, why does my Bluetooth keep turning itself on? I keep turning it off, but it still finds a way to turn itself back on

hi Apfelwurm,
why do you say it's not normal.
it always switches itself on after i update. it just did again, this time for 7.1.2.. i t also will switch on after a restore.
i never use bluetooth and make sure it's not on for any other reason.
it's been noticed by others too.

Why does my phone constantly turn off on its own as if the battery is dead?

why does my phone constantly turn off on its own as if the battery is dead? Its so annoying! Every day once my battery life span is at about 40%, my phone will start shutting down with the dead battery sign once it is down. Then after about 3 minutes i can turn it back on.

Tons of people have this problem with iPhone 4S and 5, whether they are on iOS 6 or 7. You can only hope that one day Apple realizes that this bug (software ? hardware ?) is a *real* pain. So far, they haven't paid attention.
