Did I fry my cellphone?

I have a blu android. I mistakingly left it with an app on that prevented it from sleeping while I was asleep. It was plugged in so it didn’t drain the battery.

It was hot to the touch when I awoke and tried to restart when I tried closing the app. It didn’t. Just stopped at the startup screen. I removed the battery set it aside. Let it cool then an hour or so later tried to power up my phone. I get no further then the startup screen.

Is there a way to trouble this?
