I show 35.8% battery usage for today and haven't opened the app at all.
Phone is Samsung Galaxy S24 Ultra
Android v 14
OneUI v 6.1
I very rarely use the Roku app in general. I have 3 devices, Roku Ultra, TCL with Roku, and Roku Stick.
This appears to happen more recently. No Android OS upgrade I'm aware of.
The TCL had not been connected to the internet for a while so I updated its Roku OS a week ago using the TV remote, not the app.
I do not use private listening mode and don't think I've ever used it.
I cleared cache and un-installed and re-installed the Roku App on my Android already.
