Home button is overheating

One night when I checked the phone, the home button was burning like none before and slowly i started to feel unusual warm from whole iphone 6 plus but no temperature warming sign at time.

I immediately switch it off for good. About half hour later. I turn it on again. Everything seem to be normal, however it only last for 15mins. And home button is getting hot again. Now, touch id function is not functioning even after data factory reset.

After few experiment, I find pattern of issue.

  • when lock screen, home button will get overheat in 15 mins.
  • when playing phone, there is no unusual warm after first occurrence.
  • when I plug cable in USB, iphone work surprisingly normal no heat at all. But when I plug cable in socket, home button is getting hot.

Solution I tried:

  • data factory reset

Can anyone help to explain what could be cause of issue? or way to diagnose issue? I asked authorized apple repair center, they asked me to replace entire home screen despite that only home button have heat issue.

Is it plugged in? It could get hot near the lightning port when charging. Do you have any battery saver apps installed or similar?
