Huge battery drain

Here's an interesting little twist, maybe you already knew, but I assumed YT Music would be the same as YT. YT is pre-installed and not able to be uninstalled. Music is completely removable. So I did. Now both apps have been as uninstalled as they get, having their caches and data both cleared, and updated to the latest version. So now we/I wait.
