iPhone 7 becomes very hot while playing Spotify

[atta1979]

I have an iPhone 7 with the newest version of ios11 and the last version of your app. My phone always becomes very hot while playing music via Spotify Connect. I already tried to delete and reinstall the app but I still have the same problem. At the moment it is not possible for me to play music for longer time because the accu becomes empty very fast. I hope you can help me.
