Have you tried resetting your phone?
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
Press and hold the Sleep/Wake button until the Apple logo appears.

My iPhone4s turned itself off and will not turn back on unless it is charged at all times. I need help and answers please.

And we would need more info. "will not turn back on unless it is charged at all times." is pretty obvious: the phone will obviously not turn on unless it is charged.
Describe your problem clearly.

My iphone4 turned itself off and will not come back on.

I had been using it for awile, updated, sync. I unhooked it from my PC and 5 min later is was off and will not come on or respond at all. It is pluged into the wall now and still nothing. What do I do?

The Basic Troubleshooting Steps are:
Restart.. Reset.. Restore from Backup.. Restore as New...
Try a Reset of the Phone... You will Not Lose Any Data...
Turn the Phone Off...
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
The Apple logo will Appear and then Disappear...
Usually takes about 10 - 15 Seconds...
Turn the Phone On...

My iphone 4 turned itself off and will not turn back on! Ive tried everything can anybody help me?

Hi,
My iphone was working on Friday night and when I woke up it had turned itself off!
I left it a few days and it worked again for about 30 mins and has turned back off again! Ive checked the water sensors which are fine, held both buttons down together for over a minute, nothing, plugged it into the charger, nothing, and onto itunes which shows a message to say "your iphone is in recover mode". Can anyone suggest anything else I can do as its been 3 days now!!!
Thanks

You can try to press the home button and power button and hold them for around 15-20 seconds. This will perform a soft reset similar to pulling the battery. If that doesn't help you may need to restore it.

Iphone 4 turned itself off and will not turn on

does anyone know of a way to get phone that has turned itself off to come back on?

Charge it, then try to turn it on. If it still shows no sign of life, hold home and power together for 15-20 seconds until it comes to life. If it still doesn't come to life, take it in to the Apple Store and have it looked at.

Wi-Fi turns itself off and will not turn back on

Right, I had to create a new Apple ID just to access the forum, because for some reason the ID I've had since they existed just throws up a "Page Not Found" error when I log in (backsoon/error URL). That was just the most sour and rotten cherry on this cake...
So, I have a Mid-2012 MacBook Pro, updated to 10.9.5. For a very long time my bluetooth has been unavailable. The menubar icon is grey and has the broken bolt through it, the presence pane is missing, and under System Information it finds no hardware. This was annoying but not particularly problematic, as I rarely if ever use bluetooth. I only mention this because I know the BT & Wi-Fi board is the same item.
Of late, however, something much more troubling has started occurring. My Wi-Fi has been giving me the most obnoxious problem I have ever had with a computer. At a seemingly random interval that has rapidly shortened to at most 30 minutes, sometimes as low as a single minute, the Wi-Fi will turn off without me knowing. What I mean is, while the menubar icon will still show full strength, all internet apps lose connection. If I click the icon, the pulldown menu is devoid of all networks (including the one it is supposedly connected to), and does not find any networks after searching. If I turn the Wi-Fi off (as though to cycle it off-on), it will not turn back on. If instead of looking at the menubar pulldown, I go into System Preferences, Wi-Fi is listed as "Off" already and it likewise cannot be turned on.
System Information does still show the actual hardware card as existing, unlike the BT card.
The only two changes since this started occurring (though the BT was gone then as well) were switching from a B/G router to an N router, and the October 25th 2014-005 Security Update. And yes, all our other devices (windows laptop, Yosemite MBP Retina, iPad 1, iPhone 4, 5 & 5S, HP Photosmart which I cannot print to with no wifi) all connect to the Wi-Fi fine.
So far, I have tried:
• Removing all the network-associated .plist files.
• Resetting the PRAM & SMC.
• Creating a new location in System Prefs with only Wi-Fi in it.
• Making Wi-Fi inactive and re-activating it in System Prefs.
• Verified/Repaired Permissions
• I believe I have verified the drive, but I will try again.
I have not yet tried reinstalling the system, or a clean install. The reason for this is the same reason I cannot bring the computer to a genius bar (yes, AppleCare is still active). I cannot be without this computer, I am an engineering student with finals less than a three weeks away, I have projects and homeworks due even across the coming Thanksgiving break. Luckily it waited until this weekend to become truly infuriating, so I may have a chance to try a reinstall and/or clean install.
Any suggestions further would be greatly appreciated. I'm not one to buy into conspiracy theories, but... This basically started happening a week after Yosemite came out (which I cannot yet upgrade to because its Java version breaks MatLab, and the workaround is too kludgy for me to use).

This is just like my problem on my 2011 MacBookPro. It drops the wifi connection repeatedly. Sometimes it will reconnect immediately when prompted , sometimes it takes 10 or 20 attempts to login with the router password, continually reporting "incorrect password' until it suddenly connects with that same password! Sometimes it will then drop that connection within half a minute , sometimes longer. I kept thinking it was a BT internet problem but my iMac, iPad and iPhone all remain connected to the same wifi with no problems. The iMac is also running Yosemite 10.10.1 . I understand this is a known problem. When will Apple release a fix??

My iphone has switched itself off and will not turn on

Help!!!!, My I phone has switched itself off for no apparent reason today and now refuses to switch back on again!, hit has been working fine and is less than a year old.

Reset the iPhone by pressing and holding the sleep/wake button and the home button for 20 seconds (maybe longer) until the Apple logo appears, ignore the red slider. Then turn back on. You won't lose any data doing the reset.

My iPhone 4 evidently turned itself off and will not turn back on.

I had used the phone recently, but when I went back to use it again, it was blank. Like it's dead. It is fully charged, and I had recently gotten the message to upgrade the Operating System. Anyone have a clue what could be happening?

My Nokia C3-01 turned itself off and will not turn...

I use my phone for an alarm in the morning, that was the last time I knew it was on. I put the phone in my bag when leaving for work, got it out once on the train to find no power at all. I have taken the battery out for a while which didn't seem to help, I have tried plugging the charger back in and also liking to my laptop, nothing seems to work.
Rather than driving the 70 miles to the nearest Nokia Care centre, is there anything else I can do?

Hope you left it on charge for about 20-25 minutes before checking if it turns ON ..
Else, sorry but you have to travel the distance..as being an S40 device there is not much a user can do than what is already done ...
