    Hi guys,

    I'm having a strange problem with my iPhone 4. It will shut down every now and then, randomly, for no apparent reason. The only way to turn it back on is to hold down the power button until the Apple logo appears, then wait while it re-boots itself.

    It often happens when I attempt to take a picture or video, but also happens at totally random times.

    The odd thing is that when it starts to happen, it happens a lot -- over and over again, multiple times. It's very annoying. But then it suddenly will work for a day or two or three without incident -- until it starts up again.

    Anyone ever see anything like this before? Any ideas on what might be wrong??

    EDIT: I forgot to mention that the problem seemed to start around the time I updated to iOS 7, but I can't be certain about that. Also, I've never done a jailbreak on my phone, so that's not the problem!

    Thanks! :)

    After researching this online and reading a ton of posts and articles, it appears that the problem MIGHT be a failing battery. I'm not sure if that's true, but it might be worth paying a local iPhone "fix-it" place to install a new battery and see what happens.

    If anyone thinks the problem might be something else, please let me know.

    Thanks again.

    Might be worth doing a hard reset - pressing the power and home buttons till the Apple logo appears and see if that helps. If not, then could be it needs a factory reset and delete all settings if it's not the battery either, could be an app or corruption perhaps causing the problems. I know it's a pain having to re-install everything again but could be worth it if it stops the rebooting and powering off problems.

    Thanks for the reply. I decided to have the battery replaced. So far that seems to have done the trick, but it's a bit too soon to be sure. Fingers crossed. :)

    Well the batteries are rated at around 300-400 charge cycles before they'll start to really go down hill. I replaced mine earlier this year from my iPhone 4. With an application from Cydia I was able to see that it had around 430 charge cycles and at that point was only capable of holding around 1079mAh of electricity even though it was designed to hold 1420mAh.

    Well, my iPhone hasn't shut down since changing the battery so it looks like that was the culprit. If anyone else is having the same problem, try changing the battery.
