So my phone had about a 50% charge on it. 30 minutes later I grabbed it and it was hot...but I didn't have anything running. Couldn't get the screen to come on so I reset the battery. Still nothing so I put it on the charger and turned it on. After about 30 minutes on the charger it was very hot so I pulled it off and it immediately turned off. Did my battery just fry?

I installed the new software update about 2 weeks ago.
