my 930 got really hot and skype messaging beta was the cause

[LuisMGLopes]

my phone was in my pocket and it got really hot. I unlocked it and tried to understand what happened and in the battery usage I could see that skype messaging beta was using a lot of battery, then it got cooler.
5 minutes later it was really hot again and skype messaging beta was the cause again.

so I uninstalled it and it stopped getting hot while it wasn't doing anything.

any one here had this problem?
thanks
