I have an iPhone 3GS (out of warranty, of course) and over the past few months the phone will turn off randomly, regardless of how much charge the battery has. I dealt with it until yesterday, when the phone turned off repeatedly. It stays on when it is plugged in.

I've done a full Restore (in both Recovery and DFU modes)... didn't matter. I did another full Restore yesterday, didn't install any apps, and kept the phone in Airplane mode all day. It didn't turn off at all. Today, I turned off Airplane mode and also turned off Cellular Data, and it stayed on. I installed some apps, and the phone still worked fine. I was able to run the battery to 0%.

I did another full charge, then unplugged the phone. As soon as I turn on Cellular Data, the phone turns off after a few seconds. It will restart when I hold the power button, but if I do anything on the phone, it will turn off again.

Any suggestions? Thanks in advance.

    If no change after restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup, your iPhone has a hardware problem.

    My phone 3gs is almost two years old and started turning itself off in December. My son's phone also a 3gs is a year old and has the same issue. Several friends have the same issue and it seems to have something to do with an update in November/December 2010. Please can someone tell us what to do in plain English.

    It's probably a bad battery.

    I have the exact same problem with my iphone.  I can't imagine its a battery issue, if i can confirm that with Cellular Data set to Off, the phone works perfectly fine.  If i turn Cellar Data to On, and the phone will immediately shutdown.

     

    I am also not able to start the phone unless i plug in the phone to a power supply.

     

    I noticed that the last post was in January 2012, but I don't see any correction to the issue except that its a battery, which is too easy of a response, and based on my testing not valid, since the original post states they can run the device without Cellular Data On.

     

    Mine was shutting down with 90% battery life, when I turn off Cellular, it will run to under 10% battery.

    Same thing with my iPhone 3gs running on iOS 6. Any progress so far as it started last week doing all the aforementioned things?
