Android apps running in background (and on boot)

Various apps that I rarely use seem to start on boot and run in the background.

I know Android is quite efficient at allocating memory and that background apps use few system resources, but...

If I only use the app once a month, then every single time I boot my phone, all these apps have to load even though I won't use them. It seems very inefficient, and must drain the battery significantly during boot.

Is there some way I can stop these kinds of apps from starting at boot and loading themselves into memory at all until I manually run them? My phone is rooted if that helps.

Thanks in advance for any tips! :)

    In the new phones you can sleep apps and have more control etc. via the battery section in settings.
    In older ones you may need to put it into developer mode and stop the apps from within there.
    I've never done this by the way and on my S8+ I don't need to, so I'd Google developer mode a bit before starting.

    All that said, you will be doing this for ever more as they will all probably restart on their own quite quickly.
    My phone indicates that they use very little power on startup, so choice is yours....
    Good luck.:)

    It'll make very little difference to your battery, certainly nothing close to (for instance) keep restarting your phone.

    If you run LineageOS, you can do this in the Privacy Guard.

    Ah -- I am running LineageOS.

    Thanks. I'll have a play with those settings. :)

    I've a rooted phone and use Titanium Backup Pro to freeze annoying apps. This effectively kills then uninstalls an app with a couple of clicks. Apps can be defrosted when needed but unlike an uninstall/reinstall, all the app settings are preserved. Works on system apps too.

    TBPro is a very powerful tool.

    OP, Why are you rebooting your phone so much?

    Cheers -- I'll have a look.

    Am I? How much is too much?

    As I see it, there is no reason whatsoever for a random, user-installed, non-system app to run on every boot and load itself into RAM. It's a waste of resources; a crazy idea.

    Why not have apps load themselves into memory on first use?

    I reboot my phone every month or so, so apps starting up isn't exactly using much power!

    To be fair, he's using an old phone that, presumably, doesn't manage power all that well.

    I can go months without rebooting so I wouldn't actually notice apps being loaded on boot, because it last happened months ago. If you are noticing that you are rebooting more often. You shouldn't need to reboot very often so I was wondering what issues were causing you to require rebooting.
