Trouble phone gets extremely hot

I generally carry my phone in a shirt pocket and since I got the Z-10 it has heated up about five times.  I turn the phone off and restart and then it runs normally for some time.  I can not see any pattern to when it heats up, but when it does it is hot.  I am looking for a simple answer.  It still charges well.

Re: Trouble phone gets extremely hot

The heat is caused by one of two issues, normally.


  1. Heavy data transfer (such as when syncing email/contacts/etc) after an OS upgrade, playing streaming videos and when you're having high processor usage (several working apps open at one time.
  2. Charging at times can cause some heat.


Mine showed at 122f one time. I took the back cover off and placed it in front a fan, then temp dropped quickly.

You can also simply remove the battery... no need to turn it off first.

You can also place it in a fridge for a few minutes.

Re: Trouble phone gets extremely hot

What happens if you put the phone in airplane mode for an hour?  Often the phone will get warm in poor coverage (cellular? wifi?).


For starters..

  • turn off NFC and hotspot if it's not used
  • turn off bluetooth if it's not being used
  • turn off wifi when not used to avoid wifi scanning
  • turn off cellular when it's not used (bedtime? meetings?)
  • consider HSPA instead of LTE
