I received my PinePhone and was super happy.  Then I went to charge it up and it gets super hot.  Not warm, but hot.  This is just within a couple of minutes or so.  I have never charged it all the way or even put my sim card in as I don't know if it can be used getting so incredibility hot.
Any help would be greatly appreciated.  I don't know it I need to send back for an exchange or there is a reason for this intense heating up.  Thankyou
	
	
	
	
	
 
 
	
	
		updating your system should resolve it. most distros use megi's kernel, which limits both the capacity that they will charge to, and I believe the charging voltage, but don't quote me on that.
at any rate, the kernel addresses heating issues with the default batteries
	
	
	
	
	
 
 
	
	
		I am assuming Manjaro, so in terminal type:
sudo pacman -Syu
	
	
	
	
	
 
 
	
	
		Well, when I put in the password it definitely started to do the upgrade.  Then it came up with the following:
error: failed to update core (unable to lock database)
error: failed to update extra (unable to lock database)
error: failed to update community (unable to lock database)
error: failed to synchronize all databases
Then it started to buzz.  I mean it almost sounded like a toy airplane buzz sound or something.  I thought that was strange so I turned it off and waited a couple of minutes.  No more buzzing.  I tried the update again and this time no buzz, but it said all the above again.  
I really appreciate all your help.  Looks like i need more help please.  Thank you.
