How to stop Pandora running in background
My Pandora keeps running in the background on my phone and draining my battery. I have gone into the app and have completely signed out of Pandora to stop it, but when I looks to see what apps are using up my battery, it says Pandora is running in the background. My battery will go from 100% at night to 70% in the morning, when I'm not using my phone at all. Is there any other way to make it stop running in the background besides signing out, because obviously that isn't helping. I have also previously turned off the background app refresh on my phone. Aside from completely uninstalling it, I'm not sure what else to do.
