power button seems stuck, headp jack assembly replacement did not fix
I had an iPhone with a power button that seemed stuck. It constantly rebooted. Only when connected to iTunes it stayed on. The power button is physically not damaged or stuck. But when holding down the home button it restarts. So I concluded that I needed to replace the headphone jack assembly, because that is where the actual switch is.
So I did, new headphone jack assembly, but the problem remains.
To be sure, I can press the power button, and I feel it click. There is no physical damage on the phone.
Anybody an idea what I might have to replace next? The power button itself doesn't seem to have any electronics, so I guess replacing that does not do anything?
this actually sounds like a battery problem, when the battery is dying it doesn't have enough power to boot fully hence the boot cycle. when you plug the phone in then the current is being drained from the computer source and not the battery hence why you can use the phone.
Try changing the battery , by my reckoning this would be about 2-3 years old so at the end of it's life anyway.
