Q: Iphone 4 Turned off and wont turn on

Worked immediately!!!! thanks =D

My iPhone 4S was off and I couldn't turn it on again, I was really worried about it. Was all black screen and I tried many times home + power button but nothing happened. Thanks to this support page I connected the mobile phone to my MBA and then pressed again the two buttons and it worked again! I'm very pleased, cheers.

it scared the **** out of me, as it was my first iphone, i was sure of no liquid damage... one minute before i was checking notification and then i kept it in my pocket and after some some i took it out and it went black... nothing worked.... tried everything

charging, recovery... etc

so what i did was

HOLD THE POWER BUTTON + HOLD THE HOME BUTTON

CONNECT THE USB TO IPHONE (to iphone first)
AND THEN CONNECT TO PC..

Hopefully the apple logo will appear...

Dude.. that was scary

I have an iphone 4 which goes off and wouldn't turn back on unless I plug it and let it be there. The battery shows good percentage. I did a complete restore just getting my contacts and calendar from icloud. Then it did it again after the reset. Any suggestion is welcome.

What if the phone keeps turning off after a recovery erasing everything with itunes?

You have a hardware problem, maybe a bad battery.

Last night it actually showed the dead battery icon when I plugged it and when it came back on it shoed 95% battery.

Hi,

I too have the same problem with a twist, My home button isnt working.

How do I reset ?

Unfortunately, you don't. You need both buttons working. So the only solution is to get it fixed.

you need to have those button working in order to do this..

Thanks a million for your advice. My phone went off and i got so so scared but after reading yor post, I pressed both the home and sleep button and wala

Im so thankful that i read ur post regarding this problem.My phone had the same problem and i just did what i just read here in the discussion.I pressed the home and sleep button for 18seconds..and there the apple sign appeared and finally turned on...Amazing!!!!!thnx guyz!!! :-)

Hi!
Since you have been so helpful for everyone I thought I would give you a try
My phone randomly turned off about 4 hours ago and I have tried the reset and also wall charge/usb to computer and its still not turning on.

It isn't water damaged and it also isnt a faulty battery because I removed it and tried it in another iphone.
Do you have any suggestions or is it looking bad
Thank-you in advance!

Well, since the battery is not user serviceable I would guess that you damaged something in removing it. But if NOTHING happens when you hold both buttons for up to 30 seconds then the phone is dead. If it is just a software problem holding both buttons will result in SOMETHING happening, even if it doesn't actually come back to life.

Thank you!!! I tried everything else I'd read on this thread and nothing worked until I followed your exact directions, shivendramohannn.Dude... that was scary. Eep!
