I haven't turned anything off and I stream podcasts for hours and hours each day. Maybe your app is a battery hog. I use pocket casts.Agree with this post wholeheartedly. Finally with the settings tuned down just right and 90hz off, I'm getting anywhere between 12-14 hours per day, which is plenty for my every day usage. Since Podcasts and Spotify seem to be the final things taking up so much battery on my Pixel 4, I started to use those apps on my iPad Pro, exclusively, and it has extended the life of my Pixel 4.
My screen on time isn't super high. But I find the battery basically the same as my iPhone X's or my wife's 11 pro in real life use.
