iPhone 4S shuts off at random

Hello,

I have an iPhone 4s that is about 1.5 years old and I recently upgraded to iOS 7. As many pointed out, the new OS has its "quirks" and i'll use that term lightly. While I can deal with most, I am having one major issue that is power-related. My phone will turn off at random, regardless of battery life percentage, network connectivity, productivity, etc.,. Sometimes I will be surfing the web and it will shut off, other times while I'm in the middle of a phone call, or even at rest. It will be powered off for about 45-60 seconds and then will turn back on when I hit the power button. However, if I dont notice it's powered down it will remain off and I will miss calls/appointments/etc.,.

Has anyone come across this issue? Better yet, does anyone have a resolution or advice?

Thank You!

iPhone 4S, iOS 7

Hello jilliebean11,

We've an article that provides some useful tips that can help stabilize your iPhone.

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.
