Hey there GalaxyIdo!
If you go into Device Care, go to the 3-dot menu and select Automation, you should be able to turn on Adaptive Battery Saving. If you do that, your phone will automatically turn on Battery Saver if it reckons your phone will run out of charge before you charge it again. It's pretty smart. You can also tell it not to turn off 5G and stuff.
