748mb of RAM on my phone is currently being used by random crap I didn’t ask for, like Chrome and Messenger (neither of which have been used in years), smart view, DeX, settings suggestions, gallery stories, quallcom.atfwd, visit in (none of which I’ve every actually used in any capacity AFAIK), media storage, downloads manager, game booster, game optimizing service, phone, wifi calling, contacts, contacts storage, blocked number storage, CMHProvider, Mobile Location Protocol, google services framework, and Gmail (none of which I’ve asked to run or are being used by the things I have asked to run).
These aren’t just services either, they’re fully fleged background apps with app entries and everything. And not a one was started by me.
