Finally Freed Up Space on My Phone Without Deleting Everything

I was always hitting that "storage almost full" message on my phone, drove me nuts. I'd delete photos and apps but still kept filling up again in no time. Anyway, yesterday I finally tried some tips from a random tech blog - cleared cached data, removed old backups, and disabled some apps I never even use (like seriously, who uses half these built-in apps??). Managed to reclaim nearly 8 gigs, felt like a minor miracle honestly. Curious if anyone else had luck with this kinda stuff, or found other tricks that worked better?
