Why is my iPhone overheating also when turned off?

After connecting my self made amp my iPhone restarted and started to overheat really hot. And also after I turn off my device it still keeps overheating less but still overhrating and my AUX port wont work anymore sometimes my phone switches from regular sound output to headphone one. My phone is still able to charge and to be turned on but it overheats so hard. I also tried to disconnect the battery and this worked so the phone stopped overheating but the same second as I connected the battery back to the logic board the processor (I think the black chip under the display connections) started overheating.

Help me I dont know what to do ?

Answer this question I have this problem too

Is this a good question?

Did you drop it? This happened to me after physical damage. I changed the battery and the screen but the iphone would still not work. It got extremely hot when i turned it on (most of the heat from that black chip thing you described). I could plug it into iTunes and get the "stuck in recovery mode" error message, but was unable to bring it back to life. It is possible that you shorted a fuse or something. In that case, it may be time for a new phone as there is not much you can do to fix it :(

Or you could try to take it to a local repair shop and they can do some board-level inspection and repair.

Or the self-made amp could have blown something. Too much power
