My iPhone 4 is turning itself off after 40% battery life is surpassed.

Although I still have about 40% charge on the battery, the iPhone just turns itself off, like it has no battery life at all but when i plug it into the charger, it starts up again automatically and shows that I still have about 40-45% battery life available. What is going on? How do I try to recalibrate it if I can never get it to 0% battery life? Please help.

Same case here, but mine is Iphone 3GS having 40-50% battery then a little moment boom, it shut itself off. How to fix this someone help.

My iphone 5 turns itself off even with full charge

My iPhone 5 turns itself off even with a full charge. Any help would be appreciated.

That's a very strange issue, but at the moment it could be software or hardware - the only way to find out is by restoring the iPhone.
http://support.apple.com/kb/HT4137 has all the information you need to backup and restore the iPhone.
If it's a software issue, it'll be completely fixed by restoring the iPhone!
If it's hardware, the same thing will still happen even after restoring, and you'll want to get the iPhone serviced.

Why does my iPhone 4 turn itself off and is very difficult to restart

My iPhone 4 is less than a year old but has developed the habit of turning itself off after a few hours of un-use and is extremely difficult to turn on again. It seems the only way to restart it is to hold the on/off and sleep/awaken buttons on simultaneously for many seconds. Very frustrating AND I sometimes miss important calls - help please!

Do you have a case on it that might be pressing your power on button or might press your power on button inadvertently when you touch it.

HT1296 Since I downloaded iOS 7, my iPhone is constantly turning itself off and the battery useage is twice what it used to be. I want iOS 6 back! How do I uninstall iOS 7?

I downloaded iOS 7.0.2, and now my iPhone 5 keeps turning itself off and the battery useage is twice what it was. I want iOS 6 back! How do I uninstall iOS 7?>

So, after it charged and was still plugged in, I deleted the Exchange account and then reset it holding down the sleep wake buttons until the apple logo appeared. I also changed the limit on my emails to 3 days instead of 1 week. It turned on, so I turned it off and let it charge overnight. This morning, it stayed on for 3 whole hours and then shut itself off again. I had to try 5 times to get it to come back on. Now, a message appeared that Exchange cannot verify a server, I can't see the full name of the server anymore, but it is *.hotmail.com GlobalSign Root CA from Microsoft. So I'm selecting Accept to see what happens. I'm very discouraged, I need my phone to be reliable for my work. It was reliable for 11 months without one problem, and now since I downloaded iOS 7, it hasn't been on for one full day since.

Thanks for your help. I tried plugging it in but nothing happened, I actually still had battery power left. I was able to solve my problem by holding down the power and home buttons, which reset the phone and got it started again.
Thanks for trying

Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.

IPhone 5C - Turned itself off and won't come back on.

I have owned this phone since the day it came out (20th September) and it was fine up until a few weeks ago. It decided - frequently - to reboot itself, lines would appear on my screen and the brightness would decrease until the phone turned itself off. Soon the apple logo would appear and everything would be fine. I noticed that it would do this while I was on it while it was charging or when a lot of apps were open. I avoided doing these things, but it still would happen. Sometimes it would do it and the apple logo would not appear - I learned of the holding down the home and sleep/wake button at the same time hack, and would do that to get it back on. As time went on the problem would persist, sometimes it would take a few attempts to get the phone back on - I removed some recent apps and the phone was fine for about a week.
Last Friday the phone did it again, so I decided to factory reset/restore through iTunes and then restore my backup. For a couple of days the phone was fine, up until last night where the phone switched off - thinking this was like all the other times I did what I'd usually do. But nothing, I've left it to charge, I've attempted to restore it. When I go to restore it the apple logo appears and the process bar appears, however iTunes turns around and says that it cannot restore the phone.
I went onto here to try and attempt to have it sent back for service, I put in my IMEI number, and it said that I need to turn "Find my iPhone" off, I did that and now it says that it's still on, when it isn't!
Does anyone know what I can do? Or shall I just ring them and figure out how to send it back through that?

This happened to me yesterday. This probably isn't any use to you now, but for others with this question. This morning I took the back off of my phone, and I took the battery out and plugged it in to my laptop. It immediately lit up. We put the battery back in and restored it and it works better than ever. Not sure if this will work for all, but it worked for me!

My iphone randomly turned itself off

My iphone 4 randomly turned itself off and will not turn back on!!! the battery charge was high! so no reason to die! also my iphone will not charge using iphone4 charger or usb on computer!!! have tried holding home button 4 ages and power button and also both at the same time and nothing will work!!! PLEASE HELP..!!!

Try holding down both the power and home button for about 15 seconds. If that doesn't work try plugging it in and doing that it happened to me once and that fixed it.
