Processor overheating after battery and screen replacement.

Hey, today I tried to change my battery of my iPhone 6.

Old battery removal and putting the new one in was quite smooth. To change the battery easier, I removed all four screen cables and also speaker module.

After I put it all back together, noticed that after ~10 sec. after startup, processor gets really hot. I can feel it even from the back of the phone. After I did a little research about the problem, found out that it may be the front camera cable. But the camera and front speaker works well.

Any ideas what can cause this problem?

It could be your battery too. Batteries that do not discharge properly can cause overheating. I would try to put the old battery in as a test.

Ok, try disconnecting your camera cable and booting it up.

Does not change anything.

It heats even when the screen is fully disconnected.

There must be something else wrong at the board level. My suggestion would be to send it a person or company that does board level repair and diagnostics to see what the issue is.

I’m using the phone right now. Noticed that the proximity sensor is not working at all, but the front camera and light sensor both work well. And phone heats just when the screen is in use.

So maybe I just damaged that cable of the screen and now proximity sensor shorts the processor with low current?
