10 Pro refresh rate

Hello,

I Got the refresh on auto, and show refresh is on. But it ALWAYS stays at 144Hz.

Is there a way to change it for selected apps? Like 30/60 for video players, 90/120 for social media, 60/120/144 for games based on if they are locked FPS.

Its just a waste to run 144Hz when playing a 24/25 FPS video in VLC mediaplayer. Or 144Hz when a game is locked at 60FPS

I mean the battery is great, but so much room for improvement. But would be great to see something added in the system.

Or anyone know a app for non root to do this?
