    Hi everyone,
    I'm afraid I've killed my iphone. I plugged it into a USB car charger where the polarity has been accidentally inverted ( positive into negative, negative into positive)
    The phone switched off instantly and doesn't turn on again, even plugged up.
    It seems that I 've blew something up inside. What could it be? And would the be replaceable ???
    Thanks in advance for your opinions..
    Pierre.

    I usually don't recommend doing this, but I would go to the Apple Store and play dumb.

    Not sure. I would still try to go to the Apple store and see what they say.

    What was inverted? The ground and 12V lines coming off your car battery? Or the ground and 5V lines coming off the charger? If the former, then your iPhone is definitely the least of your problems. If the latter, it's likely that your car charger is now broken and you've blown the charging circuit on the phone. If you're out of warranty, I'd say it's time for a new phone. Good luck!

    Edit: What makes you say the ground and voltage lines were inverted? Did you test with a multimeter? And how did the voltage and ground lines become inverted? I'd say that's not an easy thing to do.

    What was inverted? The car battery or how did they get switched?

    Thank you for your time and support guys! Really appreciate it.
    I leave on a boat and have t'is female car charger with 2 connectors to wire it, one is marked + and the other - . Like a dumb I wired the 12v positive to the ground and vice versa. Then plugged my male usb car charger, then plugged my phone, then the phone blacked out. Also smelled burn from the inside of the charging hole of the phone. Are you sure I can't replace this burnt charging part inside the phone?

    The charging circuit on the phone is part of the logic board. So either replace the logic board for $$$ or replace the phone for $$$. I'd say a new phone is more cost effective. Also, good quality car chargers have circuits in place to prevent damage from reversed polarization of the voltage and ground. I'm guessing you had a cheap ebay charger?

    I always like to make sure my iPhone seams are alive too.
