I have an old (but rooted) phone running Android 5.1.1 (Lollipop).
I realized it runs many background processes which I absolutely don't need.
I can stop them manually via Settings > Apps > Background processes
, however I wish to keep them disabled: they slow down the cold-start of the phone which I don't like.
So I'm looking for a way to not just disable but completely ban certain processes (i.e. ban them from starting).
How can I do this on these old versions of Android? Unfortunately Google is quite blurry and noisy for these search terms.
init
services, system apps, or user apps? See details here. How do you know they are not needed?pm uninstall
command.
