Thread: iPhone randomly shuts off

  1. #1
    Default iPhone randomly shuts off
    My iphone randomly shuts off during the day, It is possible to turn it back on but it is very annoying.

    Since the phone is out of warranty, is there a way to fix it?

    No it's not. It's an iPhone 4 on 5.0.1 with carrier Rogers 11. I think that's the carriers firmware. Baseband is up to date. Non jailbroken.

    Does it feel really hot at times? Could be overheating maybe.

    check what Simon says for the overheating issue, because if it is, nothing you can do to fix it because its on the logic board inside the iphone

    however, what you can do is try to do a RESTORE through itunes because your baseband is up to date so no need to preserve it using a custom firmware

    click the RESTORE option in itunes with your iphone connected and allow it to restore so we can determine if it fixes the issue

    make sure to do a backup in itunes before the restore first

    I think you meant 5.1.1

    5.1 has a tethered jailbreak unless u have a 3gs with old bootrom exploit

    I would try to restore it to see if it may be a software issue, and not hardware.

    If it does not work, and the issue still occur, you may have an issue with one of the hardware components overheating

    there may be an issue with either a bad battery or one of the power chips on the mainboard, which if it is, you cant fix it, you would need to replace the whole mainboard

    the cheaper way is to purchase a new battery, but as mentioned, it is not guarantee that it will fix the issue, I'm just making an assumption

    sorry bud, I wish I could assist more, but it seems like a hardware issue, which is a LOT more difficult to troubleshoot then software

    good luck!
