Iphone turned off and wont turn back on

Just got a new iphone 4 a week ago and tonight while downloading an app, it turned off, with 3/4 the battery life, and wont turn back on?

Try resetting it (hold the on/off and home buttons for 10-20 seconds or longer until you see the Apple logo, ignoring the off slider that appears first, release and wait for the phone to restart).  If it still won't turn off you may have to put it in recovery mode and restore it as described here:  http://support.apple.com/kb/HT1808.

  • My ipod has just turned off and wont come back on

    my ipod has just turned off and wont come back on but i know it had a good amount of battery left and if i plug it into my computer or docking station nothing happens please help...

    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 another cable                     
    - 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.

  • Iphone 4 just turned off and wont come back on

    Was on the phone in my car on the handsfree, then all of a sudden got disconnected. looked at my iphone 4 and it switched off. got home and tried charging it up and nothing happened, then tried plugging it into my pc to do a restore or see if i get any life and nothing !
    got no phone now and because you have to have a micro sim you have to de activate your regular size sim. so now got no sim to put into a normal phone.
    please help someone ! aaaaahhhh !!

    Hey guys,
    I was with my friend who had the same problem with his iPhone 4 today and as I was researching the problem I tried all the tricks and nothing seemed to work.
    Until I came across some info that suggested the problem was with a proximity sensor.
    Basically his phone was on(when someone called it would ring on their end instead of going straight to voicemail), but not respond tto touch or anything.
    So I held the power button and slid my finger across the screen as if to "switch" it off even though the screen was blank and waited before holding the button again to turn it back on.
    Once I did this it booted back up as if nothing happened.
    Hope this is the same problem, good luck.

  • My iphone shut off and wont turn back on

    My iphone shut off on it's own and will not turn back on. It is only a few weeks old and has not suffered any trauma. Is there a way to reboot it?

    Press and hold both the Home Button and Sleep/Wake Button together for a minimum 30 seconds or until the Apple symbol appears.

  • HT1688 my iphone just completey shut off, and wont come back on, even when connected to the charger

    my iphone completely turned off and will not come back on, even when connected to the charger. how can i turn it back on?

    Hello ozzy9294,
    Thanks for using Apple Support Communities.
    For more information on this, take a look at:
    iPhone: Hardware troubleshooting
    http://support.apple.com/kb/TS2802
    Display has no backlight or dark screen
    Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
    Try turning iPhone off and then on again.
    While connected to the iPhone charger, try to reset the iPhone.
    If the low-battery screen appears, charge the iPhone.
    Best of luck,
    Mario

  • IPhone 4S switched itself off and wont come back on. Please help?

    Hi,
    My iPhone 4S has started switching itself off randomly over the last week but would then switch itself back on several minutes later by itself. However, last night it switched itself off and no matter what ive tried it wont come back on. Ive tried the home+power button, connected to itunes and not, connected to itunes with the home button pressed. I rang the Geek Squad as I have insurance and they could suggest anything more. Im loathed to take it back to the shop as all the sales assistant will do is send it off, give me a rubbish temporary phone/brick and it will take ages to come back. I would be grateful if anyone can help please?

    Hi, my phone eventually came back to life of its own accord the next day but with virtually no battery life even though I'd given it a full charge. After it came back on I plugged it in to be recharged but the back became very warm whilst the power drained quicker than usual after I unplugged it.
    I took it to the Apple store later that day and thankfully the phone switched itself off again right in front of one of the Genius assistants. He couldn't diagnose the problem and so gave me a brand new handset straight away. Credit to Apple there and I'm so glad I didn't take it back to the car phone warehouse where I bought it from. They would have sent it away for tests for weeks.
    I've had no problems with my new handset to date.

  • Iphone shut off and wont start

    My iphone 4 suddenly shut off and wouldn't restart, i have looked on the internet and tried charging from mains, computer, pressing the home and top button together for 10 seconds to one minuite and holding the home button whilst connecting to itunes. My computer will not recognise my phone to itunes as it will not even come up and it is definately not the computer. I have re installed itunes also. When i connect to the computer it will flash with the silver apple frequently but that is all. i did not buy m phon from apple so could i still go and have them look at it? Please help

    Thankyou but it is definately not the adapter as my family are charging their apple devices on their and it s perfectly fine. I have since taken my phone to a repair shop involved with apple and they say should end my phone into apple and pay for a replacement, how can i do this?

  • My down arrow button fell off and wont' go back on

    My MBP is about a month old, and today the down arrow popped off, and won't seem to stay on.
    It made me realize that with the new design, the keyboard can't really be replaced, should I go to the Genius Bar, does anybody know what they might do to fix this?

    Hi jperkinski,
    Speaking from personal experience, many of the Genius Bars have "spare keys" laying around from old keyboard assemblies and top cases. I know I've had my MacBook keys replaced once or twice and in both cases the Mac Genius was able to get me a new keycap and the little plastic scissor that sits underneath it.
    Definitely head down to your nearest Genius Bar (make sure to make an appointment) and see if they can assist.

  • Iphone went off and wont turn back on

    Hi chlo267!
    Try using the steps in the following article to troubleshoot this issue with your iPhone:
    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 being a part of the Apple Support Communities!
    Cheers,
    Braden

  • My iphone shut off and wont turn back on, what should i do

    i need help ASAP

    You may have to try to force it into restore mode. See this support document. http://support.apple.com/kb/HT1808. You may have to do this more than once. If this doesn't work, then you will need to make an appointment with the Genius Bar to have the hardware evaluated.

  • My iMessage was turned off and wont go back on

    I went to Aruba from the US and I turned off my iMessage and what I was trying to do didn't work. I'm trying to turn it back on but when i click to turn it on under it is saying "Waiting for activation..." then under that is saying to "Use Your Apple ID for iMessage" and I'm trying to sign in with my information but when I plug it in it's saying "iMessage Activation - Could not sign in. Please check your network connection and try again". All my information is correct and even after that I was plugging in any password I could think of. Nothing is working.

    Hi,
    Try resetting your iPod:  Press/hold the home and sleep/wake buttons until the Apple logo appears. 
    If that doesn't work, connect your iPod to iTunes and you will have to restore it:  http://support.apple.com/kb/HT1414. 
    Hope this helps!
