Wanted to share my experience.
I was having problems with bluetooth cutting in-and-out when listening to podcasts or playing music. Things would play fine for a few seconds to a few minutes, there would be a brief-to-multi-second dropout, and then playing would continue. Issues with phone calls were less frequent, but happened on occasion.
I uninstalled greenify, which is a battery saving app, and I haven't had a problem since. More generally, if you are using a battery saver app, consider uninstalling it to see if it solves your problem.
I wanted to share this in case it helps others.
