How to stop apps from auto-loading at startup?

[LSMFT]

OS = Nokia 3.1 Android 8.1 Oreo branded "Android One".
I can't find any function in my phone to disallow some apps from auto-loading at phone boot startup. I'm want to control which apps load at startup because some are infrequently used but are always running in the background using resources. Is such a thing built into stock Android, or do I need another app for that function? If another app is needed, any suggestions? Thanks.

Are you having performance issues with your phone? Laggy screens, slow page loads, or quickly draining battery? It might be better to address the cause of those issues specifically rather than the old "Windows approach". Android by design is going to try and pre-cache as much as it can so that the device performs BETTER, so whatever you prevent from starting will only make your phone feel slower should you ever use those apps, however infrequently. And the memory space will be used for something else. In the 'nix world, empty memory is wasted memory.

... always running in the background using resources.

Are you sure these are resources you don't need? A lot of services are shared between apps and if you close one down, it might start it someplace else. Usually the most efficient method of optimizing your device is to let Android do it without intervention.

If you are having issues and you determine it's from a specific app that you want to continue using, you might try Greenify. I've personally never used it, but it does get some good recommendations from others.

Really you'd need root to override such behaviour. But you should understand the implications of that before rushing into it, as well as working out whether you would be addressing a real problem or just a perception.
